Shikama Dōji

Shikama Dōji (四鎌童子) is a manifestation-type demon in Seraph of the End who formed a contract with Shinoa Hīragi. Becoming her Cursed Gear scythe, the weapon was used to fight against vampires both by physically slicing into them and by its ability to generate and fire a manifested form at targets. Shikama Dōji himself would react to Shinoa's developing emotions and act to possess her.

Historically, Shikama Dōji has possessed every head of the Hīragi Family. Concurrently possessing Tenri Hīragi while occupying Shinoa's weapon, he would also seek out Kureto Hīragi to try and possess him. Expressing familiarity with Kureto's demon, Raimeiki, he would act further of his own accord in approaching Asuramaru and Yūichirō Hyakuya, where Shikama Dōji also appears to know them. Given the opportunity, Shikama Dōji would succeed in possessing Shinoa.

It would further transpire that Shikama Dōji was active during the dark ages of Greece. Going by the name Sika Madu (シカ・マドゥ), he would claim to have been the first vampire. Referred to as the First, having turned Rigr Stafford and Urd Geales into second progenitors, Sika Madu was also experimenting on a past Yu, and changed Ashera Tepes into a vampire and then a demon. A scheme to prepare for a future catastrophe involved his son, Mikaela, and other demons including Kiseki-o with Gekkouin, also Byakkomaru and Noya Hienma.

Vampire
In the past as a vampire, Sika Madu's appearance was initially unknown as he wore a flowing cloak with a hood that covered his face. It is recollected that Sika Madu appeared as a slim, androgynous person with dainty features. He had long straight, silver colored and waist-length hair. This was tied up in a braid and worn over the front of his body on the left. His fringe was at a length where sections appeared over his eyes, and on the sides of his face Sika Madu's hair reached near his shoulders. In this state, Sika Madu would also have three pairs of white feathered, seraph like wings which could materialize.

He wore clothing that was in keeping with the time period of ancient Greece. A hooded shawl like garment was embroidered with a leaf like motive. This was worn over a relatively light colored, short-sleeved top which formed part of a tunic with the length down to his feet. Other clothing options included a long white robe which had deep blue colored sections. Jewellery worn included two necklaces, and a long cuff bracelet around each wrist.

Demon
Being a demon, Shikama Dōji's true form is a slim androgynous person with horns, who appears to be around twenty-five or twenty-six years old, and Shinoa herself could not tell if the demon is a male or female. Shikama Dōji has his hair untied which falls across his back and has two curled strands that flow down to his front. On his head, Shikama Doji has two white wings curved around the top of his head and two smaller wings hanging behind his ears. Being a former vampire, he has pointed ears visible, and fangs. Unlike vampires and demons who have characteristically red eyes, Shikama Dōji's are golden.

Bearing an angelic appearance, Shikama's seraph like features include three pairs of white feathered wings protruding from his back. His elegant clothing involves a drapery style, off-the-shoulder dress with flowing long sleeves that are attached to the dress with shoulder straps. Tied around his waist is a dress piece, and he is barefoot. Although having traits of three distinct entities in his past and current state of being, Shikama Dōji tells Shinoa that he is not actually a demon.

Weapon manifestation
Shikama Dōji manifests as a dark, smoky amorphous essence with a wide "mouth," jagged fangs, and a pair of jagged horns that curve back behind his head. This "mouth" contains an eye-like glowing orb.

Possession
Upon successfully possessing his wielder Shinoa Hīragi and gaining control of her physical body, the only difference between them is that Shinoa's eyes become a pale yellow with thinner irises and pupils. Shikama Dōji's angelic wings can also form where they can still be used for himself and the body he is in to fly.

Vampire
Initially during his time as the First Progenitor, Shikama Dōji's personality was known through other's accounts of it. According to Saitō, Sika Madu eventually disregarded everyone in the vampire race, except for Ashera Tepes. Where he was involved with turning others into vampires and demons, Sika Madu would leave most of them, in favor of a specific few.

Before that time, Sika Madu was more involved in others around him. Always smiling, Sika Madu was kind and heartwarming towards Ashera upon meeting him for the first time, and treated Yu gentle and kind as well. Asking if they were hungry, Sika Madu took measures to feed them. Patient as they eat, Sika Madu made observations that Ashera held his spoon well, and had acquired the knowledge of his noble heritage. Speaking casually to Yu in discussing his height, Sika Madu was mild-mannered in his speaking. From Yu's response of what he does, Sika Madu allowed him to act freely and essentially play all day.

Willing to buy children as slaves, on more than one occasion was an instance of a dark underside to his otherwise pleasant demeanour. When it became apparent that Sika Madu was fine with a murderous seraph Yu in the room, he was also calm in requesting that Ashera leave. Swiftly intervening to seize Yu as he attacked, Sika Madu remained in control of what would have been a tense situation. Largely unfazed that Ashera had been mortally attacked, Sika Madu also took to the air at night where there was a chance people could be watching, and unemotionally cut seraph Yu's head off. Regarding the dying Ashera as a figure of curiosity when he survived, Sika Madu spent more time on analyzing what his next course of action should be. Freely admitting that he had been murdering experiments for hundreds of years, Sika Madu viewed them nothing but guinea pigs.

In focusing on tweaking with living beings, Sika Madu planned for the very long term. Wondering whether it would be a mistake to use his own blood or Yu's blood to change Ashera was weighed up in his mind. Aware that the restricted chamber where Mikaela was kept had been accessed, Sika Madu was not angered but turned to the matter the circumstances around it. Surrounded by his chosen disciples, Sika Madu spoke with purpose at desiring to prevent a future catastrophe and gave them the option to pull out. Not motivated by seeking glory, where success would likely not even be recognized, Sika Madu exercised a calm methodological patience in many of his actions.

Demon
Within cursed gear that Shinoa was using, Shikama Dōji appears to be very quiet and only shares his emotions with her. According to Shinoa, he talks within her heart, and the two seem to get along as he is addressed as "Shi-chan" in the Japanese version, and "Shi" in English. Unlike other demons, who forget their past lives as vampires when they transform, Shikama Dōji retains all of his memories.

An inquisitive personality becomes increasingly clearer after Shikama Dōji insists Shinoa will be consumed with either lust or love for Yu. In sharing his affirmations, Shikama Dōji repeatedly tells her she is much stronger than her sister ever was.

Using some extraordinary methods in trying to get what he would like, Shikama Dōji mentions it upfront but seems convinced he has some leverage in gaining it. Appearing as a scythe before Shinoa, he was afraid if she did not open her heart to him then Shikama Dōji would not be able to show her his true form anymore. With no interest from Shinoa whatsoever in seeing him, Shikama Dōji said bluntly for Shinoa to open her heart to him. Honest to a degree, Shikama Dōji shared he would not possess Shinoa as he was much too busy trying to possess someone else. Concerned that the walls around Shinoa's heart were very tall, Shikama Dōji requested that she lower them, just a little will do. In exchange, Shikama Dōji said Shinoa would get to see a few of his memories. With such fundamentally inadequate offerings failing to entice Shinoa to open herself up for possession, Shikama Dōji moved to something practical given current circumstances.

While Shikama Dōji was working to possess Kureto he offered memories that would be able to save him, then deemed Shinoa callous for not being interested. Bringing Mika into the conversation, Shikama Dōji said for Shinoa to accept him into her heart and she may discover a way to turn him back into a human. Recognizing the meaning behind such actions, Shikama Dōji spoke how he wondered what kind of look would be on Yu's face if Shinoa could do that. Honing in on what else could induce feelings in Shinoa, he mentions returning Yu's humanity to him. Still resolutely fixed on having Shinoa lower her walls, Shikama Dōji said if she did so he would tell her what he really is.

Toward people other than Shinoa, he appears serene with a smile most of the time. This remains the case even with weapons and threats of violence around him. With Kureto voicing an intent to kill him, Shikama Dōji replied he would be extremely grateful if he could do so having tried for some time. Not taking matters seriously is also shown when is stabbed through the chest with cursed gear where his reaction is to greet Raimeiki, the demon weapon being driven into him After leaving Kureto's body and possessing Shinoa completely he was quite happy with the situation.

With Shinoa as his vessel, Shikama Dōji monitors a situation before acting in response to stimuli. Not acting until he has to, when Shinoa as his host came under attack from Ferid he defended her by slicing him apart. With Crowley nearby, a vicious onslaught was launched at him too. While he was open to dialogue, it ended with the First presenting his defeated attacker to others. Pleased to show what he had done while holding the chopped in half upper torso of Ferid, the First was also keen to hear of any plots transpiring and was very eager to join in by way of drawing his scythes to attack.

Approaching Saitō, he partook in small talk on how long it had been. Watching Saitō's plan unfold, Shikama Dōji enthusiastically wondered what was going on. Hearing he was being captured, Shikama Dōji dismissed such a plan due to Saitō's lack of power. Turning to a nearby seraph but finding their arm restrained, the First in Shinoa's body responded by striking off Saitō's head. Whether it was naivety or an unrestrained desire to remove a foe's head as swiftly as possible, Shikama Dōji believed Saitō's claims that cutting a chain would kill him. With many chains springing out, the First responded by evading the weapons and gaining some distance between them.

Surprise is shown when unexpected happenings occur, and Shikama Dōji appears unsettled by them. Stunned that his communications to Ashera could be heard by Shinoa, he was willing to leave her and Mahiru having deemed them dangerous for not acting in accordance to what he anticipated. In preserving his plans, Shikama Dōji does not mind being sealed to prevent damage to his vessel. Feeling weary, he will contact allies to act on his behalf. In enacting plans, Shikama Dōji will manipulate and work with others.

History
A long time ago, the First Progenitor, known as "Sika Madu", sired the vampires of the Progenitor Council and created the laws for the vampire race. In his vampire life, Sika is with Yu as a child and buys Ashera Tepes with the promise that he will keep the boy safe. Active during the dark ages of Greece from an unlocked memory from Asuramaru, it is recalled that Sika Madu brought Yu with him to a Slave Dealer where he purchased Ashera. Tasking Yu to kindly take off the chains of the imprisoned boy, Sika Madu answers Yu that is a good question when asked if he was bought. Sika Madu tells them all to be on their way.

Leaving, he walks though a market area followed by Yu and Ashera. Turning and smiling he asked Ashera if he was hungry as his stomach was growling. Hearing Yu announce that he is hungry, Sika Madu raises that he ate not too long ago, that Yu told him he had eaten too much and felt like he would pop. Wondering if Yu is hitting a growth spurt, Sika Madu considers his response this time that he will get to be big like him to be rather cute, but cannot the say how big will Yu get. His reaction to Yu's insistence that he is hungry is to laugh and tell Ashera that they are having lunch, so to come with him.

Watching them eat, smiling as he does so, Sika Madu questioned if it was good. Not acknowledging Ashera spill some food, Sika Madu remarked that he holds his spoon nicely, he had heard Ashera used to be nobility. Cheerfully telling him not to get so glum, Sika Madu had bought Ashera not to mistreat him terribly or anything but rather to be a house boy. Sika Madu comments that here they go again when Yu declares that he is going to pop, and mentions that he thinks overeating is actually bad for one's health when asked if he thought Yu had gotten bigger, though he did not believe Yu has gotten smaller. Turning his attention to Ashera to wonder if he had finished eating, Sika Madu mimicked his wording in asking Yu if he had his fill. He has, so Sika Madu decided for them to head home.

Leading the way, Sika Madu did not show any reaction to Ashera discussing as to whether Yu is his slave, neither when asked if he summons Yu to his chamber or what he is using many child slaves for.

Later in the evening, Sika Madu is present in a room where Ashera witnessed Yu turning into a seraph. Despite the drastic change, Sika Madu gently instructed Yu to calm himself, he should be able to stop. Mentioning how he made an adjustment so that he could, Sika Madu guided Yu to take a deep breath, calm himself and stop this. Apologizing to Ashera and stating his timing was not the best, Sika Madu simply advised him to step outside slowly and close the door. Remaining composed, Sika Madu told Ashera to never mind what this is, Yu is not terribly fond of humans at the moment and to hurry up and step outside. He did state dammit when Yu advanced towards Ashera, where Sika Madu intervened to clutch Yu by the neck. Stopping Yu's lunge at Ashera, again he instructed Yu to calm himself. With Yu voicing a desire to kill all humans, Sika Madu held his arm as he instructed Ashera to quickly step outside. Sika Madu appeared unsure of what to make of Yu cutting off his own arm to get to Ashera. Although Yu succeeded in his goal of murdering Ashera and had taken off into the night sky with him, Sika Madu also possessed six seraph wings where in the air behind Yu he instantly decapitated him. Commenting only that it was another failure, and he must start over from the beginning yet again, Sika Madu watched them plummet to the ground.

Floating downwards he considered to himself that it will not do to leave the bodies here. Surprised to find that Ashera was still alive, Sika Madu wondered aloud how, with Ashera's heart crushed and his entire skeleton broken, humans do not have anything close to that kind of resistance. Moving his fingers to Ashera's face, Sika Madu uttered that pain is proof that he lives. Sika Madu could see that before Ashera died, some of Yu's blood dripped into his mouth, and that is was compatible. Finding it interesting, Sika Madu noted it seems today is the day. For six hundred years now he has continued his experiments, trying over and over, killing hundreds of thousands of human guinea pigs, but now has finally found one that is compatible.

With his wings outstretched, Sika Madu observes that Ashera has not the strength to regenerate on his own. Contemplating for a moment, he considered having Ashera drink his blood. Continuing to speak to himself, Sika Madu wondered if that is the correct answer, or is it unwise. Tossing Ashera to the ground, Sika Madu concluded that he really rather not make a mistake here. A poor choice might mean six hundred more years before he can find another one.

Picking up Yu's separated unconscious head, Sika Madu asked Ashera what does he think, whether he wants his own or Yu's blood. Either way he says Ashera will never again be able to die. Phrasing the question in a different manner, Sika Madu questioned whether Ashera had a reason to live on, if there is anything he feels he must do. Getting his answer from Ashera's eyes, he deemed it good that his eyes said that he wished to live. Guessing that he will allow him to do so, in exchange he would have Ashera be of use to him. Sika Madu held Yu's head over Ashera and allowed the blood to drip into his mouth. Intently observing that it did not kill him and Ashera is indeed compatible, Sika Madu noted that he will have to look deeper into his bloodline.

Not waiting for Ashera to regain consciousness, instead Sika Madu awaits in a large room filled with cylinder glass tanks with a black substance inside. He is beside Yu, whose head is reattached to his body with a levitating black matter floating above him. Sika Madu greets Ashera by way of registering that he is finally awake. When the dark substance extends tendrils around Yu’s head, Sika Madu casually answers Ashera's question that this place is hell. It is where poor sinners who have lost their way gather, desperately seeking to return to the light, what else could it be. He then suggests if asking the question is the one Ashera wants to ask, or whether there was something he needed to do so badly he just had to live. Sika Madu ends by pointing out that Ashera has the power to do it now.

On a veranda, Sika Madu disregards Ashera stating that he accidentally killed Yu and comments on the sun shining with its blinding light. He also does not like the sun, not since he was blamed for crimes and turned into this. Stating that the undisclosed "they" even killed his beloved child, Sika Madu mentions making his own. Finding the deceased Yu irrelevant, Sika Madu was aware that the three of them, Ashera, along with Krul and Noya Hienma, went into that room. Even when he said not to, they did anyway and Sika Madu raised whether they saw him. The corpse of Michaela kept there is Sika Madu's deceased son.

Time passed before Sika Madu decided to leave the vampire race for a distant land. With Urd Geales and Rígr Stafford as witnesses, Sika Madu ignored the devastated pleas of Krul as he convinced Ashera to accompany him to an island some call the 'Land of the Rising Sun' and become a demon "for their future." Before the two departed, Sika Madu bestows Ashera's new demon name that would fit the language of the island: Asuramaru.

In one interaction, Sika Madu was surrounded by demons Asuramaru, with Kiseki-o, and Gekkouin, along with Raimeiki and Byakkomaru. Declaring them the chosen apostles, Sika Madu requested their help to save the world from the catastrophe that loomed in the far future. Opting out was possible for there would be no glory or reward to be gained before Sika Madu asked the demons if they are determined.

At some unknown point in time, Sika Madu with his apostles were gathered in a room along with Noya as a demon as well. Holding a young Yu who is unconscious, Sika Madu stood near the clear casket containing the body of Mikaela, as black suns were floating above them.

During his thousand-year disappearance, the First Progenitor soon became a demon himself known as Shikama Dōji. As this, he would possess every head of the Hīragi Clan for generations. While possessing the current head of the family, Tenri Hīragi, he became present in Shinoa Hīragi's body at birth as the result of an experimentation using Tenri's sperm to impregnate a demon-possessed woman. As Shinoa grew older, so did the demon's influence. Consequently, Shikama Dōji was extracted from Shinoa by her older sister, Mahiru Hīragi when the former was very young. Taken into Mahiru, it quickened her transformation into a demon. Shikama Dōji was sealed into a scythe and was used at twice by Mahiru until the demon requested to be returned to Shinoa. As a weapon he was given to Guren to give to Shinoa. While possessing Shinoa and Mahiru, he was also simultaneously possessing the Head of the Hīragi Clan.

Events of 2012
On December 2nd, 2012, Shikama Dōji appears as a black scythe when summoned by Mahiru in Sanguinem where the demon cuts the bindings holding her to the cross. Later that day, Shikama Dōji is used by a vampire Mahiru to greatly increase her strength in her attack on Saitō. On December 10th, Shikama Dōji is given by Mahiru to Guren for him to deliver to Shinoa. With this carried out on December 23rd, his influence causes Shinoa to lose consciousness.

Shikama Dōji reunites with Shinoa of his own will because they were together from birth. With Shikama Dōji, Shinoa will be able to survive the apocalypse. Since Shinoa can completely close off her heart from the demon far better than Mahiru ever could, Shikama Dōji tells her she is the perfect result of the experiment she was born from, and may contact any number of demons without fear of losing control. Remarking that Shinoa currently has little desire, Shikama Dōji adds she will meet someone who will make her feel it in eight years. After Shinoa wakes up after ten hours of sleep, Shikama Dōji is manifested to protect Norito Goshi from their assailants.

Events of 2020
Eight years after the apocalypse, Shikama Dōji first appears as a manifestation when Shinoa displays her Cursed Gear to Yu. Henceforth he would continue to serve as Shinoa's weapon for her campaigns against vampires who had assumed control of the world, and when Shinoa Squad defects from the Japanese Imperial Demon Army.

Osaka Arc
After Kureto Hīragi kills Tenri Hīragi, it is revealed that Shikama Dōji has been possessing Tenri and every previous head of the Hīragi Family far before he came to possess Shinoa. Approaching as a shadow, Shikama materialized in his true form on the side of a building and declares Kureto the king of mankind. Asking what Tenri said about him, upon hearing that he was described as an old god, Shikama laughs and comments that God was more twisted than himself.

Upon being stabbed by Raimeiki, he greets the demon blade like an old friend before being slammed into a building. When Kureto tries to kill Shikama with Abaddon, Shikama commands the monster to cease its fire, and Abaddon stops. Shikama Doji reveals that he is the reason for the Seraph of the End experiment, and even those will not be able to kill him. Suddenly placing his hands into Kureto in beginning to possess him, Shikama Doji introduces himself as the first vampire.

Where Raimeiki is able to immediately halt Shikama's access to Kureto's heart, the angelic demon is stronger and was about to break through the thunder demon's guard, before being temporarily sealed off as Raimeiki gained more strength from Kureto's greed.

Some time later, Shikama Dōji speaks with Shinoa about her desire to be loved, especially by Yu. He added that Shinoa is much stronger than Mahiru. In attempting to open the door of Shinoa's mind to release her desires, he is immediately stopped by Shinoa herself. Shikama Doji is then wrapped up tightly in chains.

Shibuya Arc
After they arrive at Shibuya, where Guren, with Shinya Hīragi and Shinoa the only ones permitted to enter and meet Kureto, the First has possessed the lieutenant general. Staring at everyone in the room, Shikama Dōji has a smile on his face. When Kureto was attacking Guren, he is seen by Mahiru-no-Yo to be floating behind Kureto, and described to Guren as an unbelievably powerful monster.

Manifesting into his scythe form willingly, he awaits Shinoa inside his realm. Not showing himself, a noise indicates to Shinoa where he is. Appearing in his scythe form instead of his actual appearance behind her, Shikama Dōji tells her he will not be able to show his true appearance anymore unless she opens her heart to him. With this refused as he would possess her, Shikama Dōji explains that he is too busy possessing someone else.

Tempting Shinoa to lower her barriers against him and she should be fine no matter, Shikama Dōji even proposes to share some of his memories, ones that might save Kureto. With Shinoa remembering the value of her life, Shikama raises the prospect of turning Mika back to human, and further suggests a way to return Yu's humanity to him to pique Shinoa's interest. As Shinoa's heart starts to pound louder, Shikama Dōji continues that the demon and angel in Yu will eventually erode away his mind. When Shinoa tells him to stop where he is addressed as a demon, Shikama Dōji says he is not a demon and will reveal what he is if she lowers her walls.

Stating that Shinoa truly wants to save Yu, then declaring that he will eventually possess her instead of Kureto, the First affirms that there has never been a vessel of her caliber in all the generations he has possessed the Hīragi Family.. After Kureto was handcuffed, Shikama Dōji's shadow moves from him to follow Yu where he begins talking to Asuramaru in his sword form. Whispering to him as Ashera, when Shikama Dōji enters Asuramaru's mind, he greets the purple haired demon with his original name, Ashera Tepes. With his identity asked for, Shikama Dōji responds by telling Asuramaru that it is time to remember him. When Asuramaru demands that he leave, Shikama Dōji declines, then comes under attack from him.

Noticing and commenting about the current weapon that he is using, Shikama Dōji states he is glad that Asuramaru is doing well, as he summons numerous scythes. When Asuramaru fails to strike him, Shikama Dōji finds himself assailed by swords appearing through the now warped space around his head.

Vanishing, then reappearing closer to Asuramaru to hold him in place, Shikama Dōji tells him it is time to remember who he was, and what was done to him. As Shikama Dōji uses his fangs to bite him, he will not allow Asuramaru to borrow Yu's greed so forms a barrier around them. When Yu arrives, Shikama Dōji's physical hold over Asuramaru ends when he is summoned as a sword to Yu. After Asuramaru returns to demon form manifested, Shikama Dōji comments that watching them side-by-side together brings back memories before adding it has been a long time since he last saw Yu. Engaging in conversation with Yu and Asuramaru, he enquires if they are doing well since he has not seen them for a long time. Evident that Yu does not know him, Shikama Dōji explains neither of them have any memories of their past selves. Tempting Yu with information about his past existence, Shikama Dōji's voice possessing a spellbinding effect results in Yu falling into his desires.

Subduing him, the First moves to bite Yu. Speaking that Yu left open his heart because all he wants is to be loved, Shikama Dōji responds to Asuramaru's interjection by directing him to wait and he will take him as well. Where Yu regained his sense of self and just pretended to fall under his control, Shikama Dōji is surprised to be struck. Remarking that Yu is supposed to be another empty vessel, the First is fought by the two of them where Shikama Dōji is seemingly killed. As he disappears into thin air, his remains are carefully disposed of.

Soon after, Shikama Dōji suddenly appears unharmed, alive, and well. Where Yu and Asuramaru have dropped their guard, he tells both they are getting along well, much to his happiness. Promptly shoving his hand into Yu and Asuramaru's chests, Shikama Dōji states he has to kill the two of them now, as curse marks begin covering their faces.

With Shinoa managing to enter Yu's mind by opening a pair of doors, Shikama Dōji is wounded after her scythe is thrown into him. Commenting that this is the first real damage he has taken today, Shikama Dōji compliments her skills. Shikama Dōji tells Yu that Shinoa is in love with him, and that is the reason she came to rescue him, even knowing that it is the one thing she absolutely should not do. After sixteen years she has finally lowered the inner walls of her heart thus Shikama Dōji bids farewell to both Yu and Asuramaru, his goal for today is complete. Appearing behind Shinoa, he grabs her by the neck. After Shinoa struggles, with encouragement from Yu bolstering her resistance, Shikama Dōji is amused. Its use limited, a door opens underneath Shikama Doji and he takes Shinoa with him where the door closes behind.

Shikama Dōji is fully awakened, and now possessing Shinoa's body. When Ferid attacks Shinoa to prevent her from becoming a vampire, a scythe manifests and chains sprout from the scythe form, which cuts Ferid's abdomen bisecting him. They also cut off his left arm, with which he wields his sword. After Crowley grabs Ferid's head and throws him against the wall, the weapons start to attack Crowley until his head is slashed off.

When Ferid starts questioning Shinoa if she is the First Progenitor, the First in her body answers what if they were. Questioned what the point of of this destroyed world, the endless, meaningless, human wars, then why vampire bodies will not die, even after substantial damage, Shikama Dōji is blamed for giving this 'Curse' to vampires. The First asks Ferid what would he do if he knew this information, then states that he is not the one who made him immortal. Gripping what remains of Ferid, the First steps out as Shinoa before Guren and Shinya, along with Kureto and Mika as well. Under the impression that there is plotting afoot, the First would like to join in. Deciding to fight the group, multiple scythes are summoned above them.

Sika Madu is remembered from his time during the dark ages of Greece, that at that time he has already been active for six hundred years. Buying Ashera as a slave, his experiments resulted in transforming him using Yu's blood. Sika Madu also possessed six wings in Asuramaru's memory of him.

Back in the present day, the scythes that Shikama Dōji generated shower down on Guren and Kureto. As reports arrive that the Hyakuya Sect have arrived, the First aware that Rigr is behind this movement. Ceasing their attack, the First smashes their way out the window with Shinoa's body. Arriving where Mirai Kimizuki is being held activated as the Seraph of the End, the First politely returns Saitō's greeting and adds it has been some time. Ignoring Mirai in between them, and Kimizuki nearby, the First warmly asks Saitō how many years it has been, and whether he has been well. Not reacting to Saitō's chains being deployed, or the sudden arrival of Basteya Irclu with another Hyakuya Sect soldier appearing, the First is instead joyfully intrigued what they are all doing at hearing that the unification spell is ready.

Deeming the plot to restrain them as funny, the First regards the opposition as weaklings and asks if they can really do that. They pay attention to Basteya and their accomplice beginning the ritual using spell tags. With Saitō using the chains to stab into his own army, the First deduces that he is absorbing their life energy, and wonders how much more powerful that could make him. Brushing off Saitō's desire to test it on them, the First remarks how dull this is before announcing they will be on their way now. Reaching towards Mirai, the First has their arm wrapped tight with one of Saitō's chains. They free themselves by cutting Saitō's head off with a sweep of their hand.

With Kimizuki taking Mirai away at Saitō's suggestion, Shikama Dōji claims if he joins up with his group he will wind up as his guinea pig instead of theirs. They then address the matter of Saitō's head which is now floating in the air, connected to his body by a chain. Enquiring what happened to his head, the First does not recall constructing Saitō like that. Asking if they cut the chain would Saitō die, the instant the First hears that this is the case, they do not hesitate to sever the neck chain. The result of this action is not the death of Saitō, but an abundance of chains bursting out in all directions which the First runs to avoid. Annoyed, the First says that Saitō did not die at all and lied to them. Smashing their way through a window, outside, Shinoa's body produces Shikama Dōji's angelic wings to fly themselves in the air. Where the chains are advancing outwards from the building, the First is confronted with chimera like beasts unleashed by Saitō. Noting they seem dangerous, the First feels it looks almost like a beast of the apocalypse

Having their angelic like wings complimented, the First answers it is ironic having these wings despite losing the sun forever and falling into darkness, all because of a simple taboo. They start summoning ethereal scythes around their angelic wings, before disconcertingly announcing that if Saitō keeps interrupting them like this, then they will punish him. Asked by Saitō if they finally manage to see him, the First can present a smile. With Saitō directing his chains and his beasts to stab the First, they respond with their scythe, ordering the ones summoned to slice Saitō to bits. The collision between the two powers causes multiple, and massive explosions around the area. Remaining calm, the First's scythes clash with Saitō's chains despite some drawing close to their head. An attack emitted from the battle forms a thin release that has the strength to fire entirely through nearby buildings. Shikama Dōji notices that something has happened, sensing Noya's awakening, and questions Saitō if it is his doing. The battle continues and aware that something happened, Shikama Dōji questions Saitō out of curiosity as to whether he arranged that. The First knows Saitō would not challenge him without a trump card or three, even two-thousand years ago he was not that foolish. The First's power is felt to be stronger by Saitō. Preparing to launch an enormous scythe, the First has no intention of allowing Saitō to use that trump card, whatever it is and affirms that they are done now. Observing Guren's arrival, they ask Saitō if this demon is his trump card. Voicing the intent to kill Guren, scythes are directed at him before the First appears taken aback at seeing them halted by Mahiru and Noya. They are further surprised at noticing a sinful key in Guren's possession when he tosses it to Saitō but is confident that one key is not enough. Interrupted by Saitō who claims that according to his calculations, considering that the First has yet to manifest his real body, three evil keys should be enough to seal him, the First adamantly states it is not nearly enough. All the while blocking an attack from Guren, the First is sure that he cannot hit him with that with what little speed Guren has. The first is then suddenly no longer under attack from Guren as he and his demons are betrayed by Saitō. After Saitō has been dealt with after Ferid's intervention with Jigenso, the First sees Guren, Mahiru and Noya acquiring a sinful key each and is surrounded with a sinister power entrapping Shinoa. Even with the power emitted from the sinful keys, the First is confident they could certainly resist this if they chose to, but that would break Shinoa as his vessel. Conceding, he allows Guren and the others to seal him for the time being. As Guren suggests how about he make it an eternity, Shikama Dōji delivers a final laugh.

Visualized, Shinoa considers that the demon army is Shikama Dōji's creation as she contemplates who they can side with. With Shinoa's scythe activated, it is the cursed gear manifestation, addressed as "Shi" who appears. Obeying Shinoa's order to grab a wall, Shi remains connected to the physical weapon and ends up pulling Shinoa out of the moving vehicle

Post-Shibuya Arc
The historical time in the dark ages of Greece where Sika Madu was approached by Ashera with a deceased Yu is recollected. He was aware they had entered his forbidden room, and discussed the sun. Sika Madu commented undisclosed they also killed his beloved child, Mikaela. The First is referred to as Master Sika Madu by Gekkouin who is working with Kiseki-o and Asuramaru in opening a pathway to help contain The King in his own world of desires. Later he is mentioned by Mahiru that Shikama Dōji will be able to locate Mika much more easily and he will go and capture him right away if the curse-amplifying drug they injected into Mika should wear off. In a flashback eight years ago in Sanguinem, he is discussed by Mahiru concerning how she had the first cells implanted into her body, where the Shikama Dōji scythe was manifested. That Sika Madu is using Ashera to this very day was discussed. Shikama Dōji was suppressed by Mahiru injecting a needle into herself so he could not hear the deal she brokered with Krul.

In the present, when Krul attacks Shinoa, her hand is blocked by a barrier and Shinoa now has six large wings, as the First has regained control of her body and was eagerly awaiting what Krul could tell him. Speaking through Shinoa, the First informs Krul that wasn't nice. With Krul proclaiming that he is their true enemy to Kimizuki, and Mitsuba, with Yoichi, then that he want to use Mahiru's sister, and Mikaela as his experiments, the First silences her with a hand. Speaking to the others that Mikaela is his precious son, they are trying to save him, they add that he is their only true ally the squad has.

Suddenly dropping to his knees, the First finds out that his consciousness is fading. When he learns that Guren and Mahiru plans to turn Mika into a cursed gear, the First is steady as he telepathically contacts Ashera. Alerting him that the humans are headed 'there', the First directs him to capture Mikaela's soul before the humans do.

Appearing fatigued in his sphere with a chained Shinoa held above, the First sees her break free. On if this is something he did not anticipate, the First does not reply back. Hearing that Shinoa will keep her heart half closed and possess him, as Shinoa conjures her scythe, Shikama Dōji does the same and fires three of them towards her. These are deflected and Shikama Dōji is surprised that again Shinoa is stronger than anticipated. Responding that she was not this powerful before, he questions if whether she was hiding her strength. Questioned if he is not sure that all of humanity was underestimated, Shikama Dōji is then is stabbed through the chest by Shinoa's scythe.

With Shinoa intending to suppress him to confine and bind him, Shikama resorts to contact Ashera in his mind, yet the communication to capture Mikaela's soul before the humans do is heard by Shinoa. Shocked that she can hear his thoughts, Shikama Dōji is asked if this Ashera is Asuramaru, one of his allies. Where Shinoa reacts by meaning to let Yu know right away, Shikama Dōji will not allow it. Aiming a scythe at Shinoa, it is allowed to hit her where them momentum carries her away from him.

As Shinoa mockingly sticks her tongue out at him and means to awaken, Shikama Dōji raises his hands and orders her to sleep. When Shinoa refuses, and announces she can wake up, Shikama Dōji speaks to force her to sleep to effectuate her to do so. After Shinoa draws upon her feelings, where curse marks envelop her face and a sharp horn appears out her forehead as she becomes a demon, Shikama Dōji fails in inducing her to sleep. Shikama Dōji remains subdued with Shinoa holding her scythe in his back. Word was sent to Asuramaru that he will wake up soon.

Standing with Shinoa's scythe in his chest, Shikama Dōji is roused from his slumber and shares that he is waking. Aware another dosage of the drug has been taken, the First feels it is the same one as before and he knows how to handle it now. Answering if Shinoa's attempts to keep him down are to protect Yu, the First says to let him help her with that desire, he will give her power. With Shinoa raising dark clear barriers around herself, Shikama Dōji comments as expected her heart walls are strong, she is gifted. If Shinoa would let down those walls Shikama Dōji would have made her wholly into a demon, then she would not have any worries at all. Not answering what he is looking at, the First states he is simply glad to be in time. Announcing that he must be on his way now, the First intends to save his precious Yu and Mikaela.

Departing, the First answers Shinoa that he has no need to speak of what he is going to do to Yu and Mika, nor is it any of her business. Staying inside the hearts of Shinoa and Mahiru was riskier than he anticipated, so Shikama Dōji thinks he will leave. Thanking her for everything, Shikama Dōji glances back upon hearing he can possess Shinoa. Wondering if this is so she can protect Yu, he feels it is true as he can sense that is the desire Shinoa has hidden in the corner of her heart, then remarks how brave of her. Saying bluntly he is abandoning her, the First explains how in all these millennia, Shinoa and Mahiru are the first to ever surpass the parameters of his plan. Revealing that they make him feel fear, Shikama Dōji adds also reverence, and beauty. However, he still has his objective to complete so once again bids Shinoa farewell and thanks her for everything. After a scythe is cast at him, Shikama Dōji states that is his power. Raising his hand, Shinoa's power is gone.

Within one of Yu's memories from in Ancient Greece that Mika is accessing, Sika Madu is seen walking into a room with Raimeiki, and Byakkomaru, along with Kiseki-o and Gekkouin who are around him. The memory of Sika Madu speaks as the present day one in that it can discern and speak to Mika who is in a past Yu's body and seeing this recollection from his viewpoint. Making eye contact and pleased to see him, Sika Madu is amazed that he could come back to this quite far from the past. Summoning four scythes, he will not let him get away. When Mika shouts to himself that he has to wake up right now and get out of here, Sika Madu speaks for him to sleep. While Mika focuses his attention on Yu who says he can become his demon, Sika Madu can apparently hear this too as he shouts for him to sleep.

With electricity emanating from his hand, Sika Madu attempts to force Mika to sleep. Thinking that it is too soon for Mika to become Yu's demon, Sika Madu feels he can stop him and focuses on inducing tiredness. As Yu speaks to Mika, Sika Madu shouts no, he will sleep. Aware that they are together in a realm talking, Sika Madu speaks that he is sorry, but Mika becoming Yu's demon is not going to happen. Where he stands in the memory featuring the lab like room with his apostles around him, Sika Madu raises his hand to replace that scenario with a barren landscape where Yu and Mika as children sleep before him. Conjuring two scythes, the First remarks that is a lovely dream that they are having, so how about they sleep a while and enjoy it.

In control of at least three scythes, Sika Madu regards the sleeping Yu and Mika and bids them pleasant dreams. Glancing to his side, he remains with his back turned to a large pentagram made out of chains that has appeared behind him out of two coffins. Speaking whether Rigr is still trying to cling, Sika Madu comments this is starting to grow annoying. When the chains fire towards him, glimmering scythes are ordered to shred them while Sika Madu notes how he is already short on time. Deciding if Saito despises him this much then he can die, Sika Madu launches scythes into a coffin the chains are coming out of.

As ever more chains arise, Sika Madu says he is tired of bothering with them so thinks to ignore the situation. Right now he has to pin both Yu and Mikaela with a scythe and make sure they are both properly sealed. Noticing Kimizuki and Yoichi in his location, the First asks who they are. Without a word from them, Sika Madu claims their demons are his servants then questions how they are here. After Kimizuki shouts for Yu to get up, the First appears livid. This was not a part of his plan, and it is starting to aggravate him. While he wants them to die, Sika Madu finds his materialized scythes are slow. Gathering that it is another dosage of poison, Sika Madu declares he has still got enough power to kill them all. Swinging his scythe repels an onslaught of chains. When Yoichi calls for Gekkouin, he orders him to cease listening to that human.

Using his scythe to block Yoichi's archery fire, Sika Madu then finds Kimizuki has drawn close. A coffin has been summoned to send him to another world, and the First shouts the insects are in his way. Slicing Kimizuki at the waist in this demon realm, Sika Madu can move past his scythe being grabbed to attack Yoichi as well. With them out the way, Sika Madu speaks further that it is time to see to Yu and Mika. A surge of lightning, and Yu saying for Mikaela to slice them open leaves Sika Madu shocked as he says to wait.

Powers and Abilities
The First possesses expansive knowledge about seraphs, demons, vampires, and humans having been performing experiments for six hundred years. Killing hundreds of thousands of human guinea pigs over this time, the First also created vampires and demons. In acquiring knowledge, he was aware that Ashera was nobility. He also knew how to save Ashera from dying, a supreme ability from the ancient world to the present day.

Part of his experimentation involved allowing it to extend its many tentacle like projections and make contact with Yu's head. The First also managed to reattach Yu's head despite him being decapitated. In addition he keeps a corpse of a "Mikaela". According to Noya, the First has the ability to clone Yu's if one should die.

Vampire
He would have possessed strength and speed that are much greater than a human's, along with having rapid regeneration, in addition to immortality and eternal youth. As the former First Progenitor, Sika Madu was likely the most powerful vampire that has ever existed, vastly more powerful than the members of the Progenitor Council which was composed of Second Progenitors and lower ranked vampires. Urd Gaeles and Saitō were such members, with the latter saying that the gap between him and the First Progenitor is great when Saito expressed shock that Ferid was able to capture Krul. The First has been shown to be capable of effortlessly overtaking and decapitating Yu with a single swift strike from one hand despite Yu being in his seraph form.

Demon
As stronger vampires make stronger demons, Sika Madu continues to be the most powerful known being in existence as the demon, Shikama Dōji.


 * Demon's thrall: If other demons are to go by, Shikama Dōji may enter the dreams of his host and use their memories to torment them in a battle of wills to possess their body. Shikama Dōji has yet to be shown using this ability.
 * Possession: A basic demon ability, but Shikama Dōji is able to somehow possess more than one person simultaneously as he was able to be with Mahiru and Shinoa while still possessing the head of the Hīragi Family. After possessing Shinoa primarily she inherited his ability to summon scythes and use his angelic wings.
 * Near invulnerability/immortality: Shikama Dōji has implied that essentially nothing, not even a Seraph, can kill him. Even after getting stabbed and electrocuted by Kureto's lightning based cursed gear, Shikama Dōji still appears to be unharmed.
 * Supreme angelic/demonic command: Shown to have command over Seraphs and demons as he ordered Abaddon and Mirai to cease their attacks and they complied with his one word order.
 * Other host thrall: Shikama Dōji can enter other hosts and he can have complete control on the host body, such as when he entered Asuramaru mind and is able stay there even if they would force him away as Asuramaru was unable to.
 * Barrier sealing: Able to form a barrier, he can seal who he has contact with in it. They can be kept with him and prevent them from escaping, displayed when he was forming one to prevent Asuramaru from escaping to take Yu's greed.
 * Basic form: He takes the form of a scythe with a glowing green blade. Shinoa can call out the demon to attack an enemy. A manifestation-type demon weapon strongest at mid-range. Shikama Dōji himself can summon numerous scythes as a means to attack.
 * Miniature form: A black pen-length rod that is more convenient to carry. This can be wordlessly materialized into the fully sized scythe.
 * Perception: The weapon can detect anything that comes within the radius of his scythe.
 * Manifestation: At Shinoa's orders, a large smoke like creature can be manifested that will attack whoever she chooses. It is shown he can materialize on his own into his scythe form if he wants to as he did in Shinoa's hand.
 * Scythe proficiency: An expert in wielding scythes, Shikama Dōji can materialize numerous scythes and attack from a wide radius. Not losing this ability when possessing a host, in Shinoa's body he can also levitate scythes for barrage assaults as well. Additionally he can summon numerous ethereal scythes and whirling them rapidly forms a circle similar to a halo appearance of scythes as a particularly effective and deadly attack. A seemingly endless amount of scythes can be generated.
 * Sleep inducement: a verbal command to sleep can result in a target violently hurling to the ground. Sika Madu having his hand outstretched may contribute to a pressure that can fracture the ground and result in an electrical generation around him. The force of which he speaks the words and the amount of times the order to sleep is said appears to heighten the likelihood. He has used this ability to try and prevent targets from fleeing. When successful, the target does not appear to know that they are asleep.

Seraph
Shikama Dōji says he is not actually a demon, and possesses six large feathered seraph like wings. Even after being bound to cursed gear, Shikama Dōji has not forgotten any of his memories or the knowledge he has where other demons have. He exerts control over other seraphs, and makes a comment on the nature of god that seraphs are associated with, while denying that he is a god himself.

Scientific abilities
It has been stated and implied by the oldest of the vampire Progenitors, Urd Geales, Rigr Stafford, Ashera Tepes, Krul Tepes and Noya Hienma that Sika Madu during his days as the First Progenitor, frequently dabbled and experimented on supernatural entities using both what appears to be scientific and magical methods with varying results. Such scientific experimentation was used in an ancient setting, and during a period of intellectual stagnation in the wider population. Sika Madu also has a large room filled with cylindrical glass tanks with multiple black suns.

Human creation
As seen during the memories of the three third progenitors, and supported by Noya, Sika Madu had successfully created what they called his "human creation technique". Successfully creating a method to produce Yūichirō Hyakuya from a single disembodied eye, he could be created as a fully formed child capable of speech and featuring his mannerisms. These appearing to serve as an everlasting supply of test subjects for his seraph experiments to make it more stable. From Noya's view, Sika Madu had created so many that he would not notice if one or two Yu's were murdered by him. Although the exact process of how he accomplishes it is unknown, it was stated that the method itself was still imperfect over one thousand years ago in Ancient Greece. However by the time of the 21st Century, it was stated by Noya that that Sika Madu had already likely perfected the method due to him seeing the fully functioning and mature, Yūichirō Hyakuya. He was also impressed with what he saw as a Mikaela.

Seraph experiments
It was also apparent that Sika Madu also possess the knowledge and research and complete the method to either create, or summon the Trumpet of the Apocalypse and placing it inside a human host. With him having been known to repeatedly experiment on making one and was seen to have repeatedly placed them inside his Yu clones. Having the Japanese Imperial Demon Army continue this, Shikama Dōji would comment that the Fifth Trumpet within Mirai that could summon Abaddon was his experiment.

Vampiric experiments
He was interested that Yu's blood is compatible with Ashera having turned him into a vampire. Allowing Ashera to live, Sika Madu would have him be of use to him. It was third progenitor vampires specifically that Sika Madu had transformed into demons, and with the second progenitors left it would seem having vampires turned into demons for his purposes was a plan. During his reunion and battle against Saitō, the First was surprised at the additional features that he had implemented into his body. Speaking about him as if he were a construct, Shikama Dōji mentioned he did not recall putting Saitō together like that.

Seraph of the End: Vampire Reign
"It's all right. There is nothing to fear about becoming a demon. I shall stay with you always, even after you have become one."

- Speaking to Ashera Tepes in a flashback of 1,000 years prior.

"Come, it's time we left. You must become a demon. Oh yes, what should I call you once you've become one? Hmm... Since you will be reborn on an island some call the 'Land of the Rising Sun,' let us tweak your name to fit their tongue-- Yes. You shall be called Asuramaru."

- Updating Ashera's name to Asuramaru to fit in with Japan.

"Hello. It seems one who could kill Tenri has finally appeared. So you are the new King of Men."

- Approaching Kureto Hīragi soon after Tenri's death.

"Aha ha ha! Oh, I am not God. He has a far more twisted personality than I."

- Laughing in response to Kureto's words and denying he is god, then commenting on his personality.

"Oh. Hello there, Raimeiki. Welcome home."

- Reacting to being stabbed in the chest by greeting Kureto's demon within his sword.

"If you can, I would be quite grateful if you would. I've been having such trouble trying to die for quite some time now."

- Embracing Kureto's intent to kill him.

"Halt. Goodness. Don't tell me you meant to kill me with that? That is an experiment I have had humans working on for me for quite some time now. It is not yours. Besides, that is not enough to kill me in the first place. Now then... I shall possess you next, Kureto."

- After taking control of the Seraph of the End, the First is aghast at the notion it could be used to kill him. Asserting it is his, he then acts to assume control over Kureto.

"My name... is Shikama Dōji. I am the first vampire."

- Sharing his name to Kureto, and revealing his background.

"Aren't the virginal the ones who have the most lustful imaginations?"

- A question for Shinoa.

"Aha ha! You know that full well. She was sixteen. She was so passionate about everything, wasn't she? Both in life and in death."

- Speaking to Shinoa about Mahiru when asking how old Mahiru was when she slept with Guren.

"Of course, you don't. Because you're stronger. You are so much stronger than she ever was."

- Remarking that Shinoa is stronger than Mahiru.

"Don't you think it's about time you opened that door? You can build walls in your heart. Tall, thick walls. Those walls will keep the love and the lust... the joy and the sadness... all of the emotions at bay."

- Pressing Shinoa to lift the emotional restrictions on her emotions.

"What does a human have if they have no passion?"

- Working towards Shinoa embracing her emotions.

"You lie. You want to experience love. When you watch Yūichirō Hyakuya, you feel your heart race. Why don't I get this ball rolling by opening that door?"

- Picking up on Shinoa's feelings, and taking them further.

"Ashera, you poor child. You must have been so frightened. But it's all right now... From now on, I shall keep you safe. Yu, kindly take off his chains."

- When Sika Madu buys Ashera Tepes as a slave, where he had a young Yu with him as well.

"Don't play innocent with me. I see straight through you. You know who I mean. You know it all. You just pretend that you don't notice. You're playing at being the dispassionate observer."

- Objecting to Shinoa's claims.

"I won't. I can't. You were not made so that I could. You have a heart of ice, so that no matter how much of your heart is devoured by a demon, you can retain perfect control."

- His comments when denying that he is trying to possess Shinoa (which he later would do).

"You lie. You are interested in a way to save Yūichirō. Aah, at this rate it won't be long before your walls come down. When they do, I'll no longer need Kureto Hīragi. I'll be able to possess you instead... I can hardly wait. In all the hundreds of years that I've possessed the Hīragi Family, not once has there been a vessel of your caliber--"

- Feeling Shinoa is lying, and that it is only a matter of time until he can possess her.

"You liked looking up at the sky. At least... that is what you once told me."

- Reminding Asuramaru of his words.

"I see you two are as close as always. That makes me so happy... But I'm afraid your days of being friendly and close are over. I have to kill you now."

- Hinting of Yu and Asuramaru's past familiarity, but meaning to murder them.

"I knew she was amazing. That is the first real damage I have taken today. Tell me, Yu... Did you know? She is in love with you, you know. So much so that she came to rescue you, even though she knew that was the one thing she must never do. Out of desire for you, she finally lowered the inner walls she kept tall and strong for sixteen years. To save you... To rescue you... She allowed me in. My goal for today is complete. Goodbye, Ashera. Yu. Until we meet again."

- Revealing Shinoa's feelings to Yu and Asuramaru, then about to succeed in his goal to possess her.

"Oh dear. I could certainly resist this if I chose to, but that would break this vessel. All right, all right. I’ll allow you to seal me for the time being."

- Enduring the effects of the sinful keys, and relinquishing Shinoa from his possession.

"As I expected. Your heart's walls are strong. You're gifted. Oh well... If you'd let down those walls... ...I would've made you wholly into a demon. Then you wouldn't have had any worries at all."

- His response to Shinoa raising barriers around herself, and views on her and demons

"I was simply thinking I'm glad I was in time. I must be one my way, now... ...to save my precious Yu and Mikaela."

- Leaving Shinoa in order to save Yu and Mika

"I'm abandoning you. In all these millennia... you two sisters are the first to ever surpass the parameters of my plans. You make me feel fear."

- Views about Mahiru and Shinoa.

"You can't. Not yet. It's too soon for you to become Yu's demon. I can stop you. Sleep!"

- His thoughts on Mika responding to Yu, and his plan revealed for them both.

"All right, then. If you despise me this much... ...you can die."

- Responding to Saito's attack.

Trivia

 * The Katakana for his appearance in chapter 57 of the manga accidentally spelled his name as "Shigama Dōji". This was corrected in the official published volumes. The past Yu addresses him as Siga Madu, which may be a child's pronunciation of it, or a variation of the name Sika Madu was known by.
 * This demon is the only one known to possess multiple people at one time thus far in the series.
 * He possesses Tenri Hīragi at the same time he is with Shinoa and Mahiru.
 * After Tenri's death, he possessed Kureto Hīragi at the same time he was possessing Shinoa.
 * His name as a vampire was "Sika Madu", and this became "Shikama Dōji" when he turned into a demon.
 * Shikama Dōji is described as an unbelievably powerful monster by Mahiru-no-Yo, an unknown monster by Guren, and a strong monster by Asuramaru. All potent indications of his strength coming from them.
 * Shikama Dōji already had three pairs of white wings as a vampire (as Sika Madu) even before becoming a demon.
