Shikama Dōji

Shikama Dōji (四鎌童子) is a manifestation-type demon who formed a contract with Shinoa Hīragi, and became her Cursed Gear. While possessing Shinoa, he also concurrently possesses Tenri Hīragi and Kureto Hīragi. Historically, he has possessed every head of the Hīragi Family until he primarily possessed Shinoa completely. He's one of the main antagonists in the series.

He later leaves Shinoa's body due to Guren, Mahiru and Noya acquiring sinful keys sealing him, for the time being.

He is later revealed to be former First Progenitor of the vampire race, Sika Madu (シカ・マドゥ), who disappeared a thousand years ago until turning up again as an angelic looking demon.

However it is unknown how he was turned into a demon since he was the First Progenitor himself, including how he was turned into a vampire as well.

Vampire
Sika Madu's appearance was initially unknown as he wore a flowing cloak with a hood that covered his face in Krul Tepes's flashback. He is shown in Asuramaru's flashback which reveals him as a slim, androgynous person with dainty features and has straight silver waist-length hair that is tied up in a braid with a fringe. He is also revealed to have had the three pairs of white wings first seen in his demon form.

Demon
The light novels, Shikama Dōji's true form as a slim androgynous person with horns, who appears to be around twenty-five or twenty-six years old, and Shinoa herself couldn't 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 flows down to his front. On his head, he 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 and fangs. It has yet to be revealed if he red eyes.

To emphasize his angelic appearance, Shikama has three pairs of white feathered wings protruding from his back, and wears 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.

Demon Weapon Manifestation
Shikama Dōji manifests as a dark, smoky amorphous creature 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
Later Sika Madu successfully possess his wielder Shinoa Hīragi and gains control of her physical body,the only difference being that Shinoa's eyes become a pale yellow with thinner irises and pupils, and she later also gains Sika Madu's angelic wings during his battle against Saitō.

Vampire
Not much is known about his personality during his time as the First Progenitor except that according to Saitō, Sika Madu eventually disregarded everyone in the vampire race, except for Ashera Tepes.

His true personality later revealed in Asuramaru's flashback. Always smiling, Sika was kind and heartwarming towards Ashera as he even bought him as a slave in order to free him, he treats Yu gentle and kind as well. He also goes to all the trouble to feed both Ashera and Yu when they were hungry. and treats Yu very mildly during his daily life. However Ashera mentioned he buys many slave children enough to be a slave dealer which means he buys children often meaning he keeps buying children slaves since they die very often casting them aside. Later he admitted that he views them nothing but guinea pigs for his experiments.

Demon
Shikama Dōji appears to be very quiet and only shares his emotions with Shinoa. According to Shinoa, he talks within her heart, and the two seem to get along as Shinoa calls him "Shi-chan" in the Japanese version and "Shi" in English.

However, he eventually reveals his true personality by insisting Shinoa will be consumed with either lust or love for Yūichirō Hyakuya. He repeatedly tells her she is much stronger than her sister ever was.

Toward people other than Shinoa, Shikama Dōji is shown to be serene with a smile most of the time, due to him being pretty much immortal and near invincible, which makes him unperturbed by threats and the killing of his former host, Tenri Hiragi. This knowledge of being near immortal also doesn't let Shikama take anything seriously, which can be seen when Shikama responds to being stabbed by Kureto with a greeting to Raimeiki, the Cursed Gear being driven into his chest.

Near-immortality also has Shikama Dōji wanting to die, as he says to Kureto that if the latter manages to kill him, he'll be extremely grateful of that as being unable to die is painful. Although immortal, Shinoa manages to injure him with her scythe however he soon heal but is surprised as he never taken any real damage before.

Unlike all the other demons, who forget their past lives as vampires when they transform, Shikama Doji retains all of his memory as a vampire and demon intact, this is further revealed when he remembers both Yu and Asuramaru who he calls him by his previous original name "Ashera Tepes".

He leaves Kureto's body and possess Shinoa's body completely, and is quite happy with the situation, since this was his goal all along, even dragging Yu and Asuramaru as part of achieving his goal.

With Shinoa as his vessel he acts violent, and ruthless, and enjoys torturing others and killing. He also loves toying with others, as it is fun for him playing around for his own amusement. Nevertheless, as she is his host, he protects Shinoa's body all the time.

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 buys a slave named Yu, and then later on, buys Ashera Tepes with the promise that he will keep the boy safe.

Sika Madu is revealed to have been 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. He tasks Yu to kindly take off the chains of the imprisoned boy and answers him that is a good question when asked by Yu 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 asks Ashera if he is hungry seeing his stomach is growling. Hearing Yu share 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. Sika Madu wonders if Yu is hitting a growth spurt and considers Yu's 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 asks if it is good. Not acknowledging Ashera spill some food, Sika Madu remarks that he holds his spoon nicely, he has heard Ashera used to be nobility. He cheerfully tells Ashera not to get so glum as he bought Ashera not to mistreat him terribly or anything but rather as a house boy. Sika Madu comments that here they go again when Yu declares that he is going to pop, and tells him that he thinks overeating is actually bad for one's health when asked if he thinks Yu has gotten bigger, though he does nor believe Yu has gotten smaller. Turning his attention to Ashera he asks if he is finished eating and mimics Ashera's wording asking Yu if he has had his fill. He has and Sika Madu decides for them to head home.

Leading the way he does 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 witnesses Yu turning into a seraph. Despite the drastic change Sika Madu gently instructs Yu to calm himself, he should be able to stop with Sika Madu having made an adjustment so that he could. He advises Yu to take a deep breath, calm himself and stop this. Apologizing to Ashera, he says his timing was not the best and simply advises him to step outside slowly and close the door. Remaining calm, Sika Madu tells 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 does state dammit when Yu advances towards Ashera and Sika Madu intervenes to clutch Yu by the neck. He stops Yu's lunge at Ashera and again instructs Yu to calm himself. With Yu voicing a desire to kill all humans, Sika Madu holds Yu's arm as he instructs Ashera to quickly step outside. He appears unsure of what to make of Yu cutting off his own arm to get to Ashera. Although Yu succeeds in his goal of murdering Ashera and takes off into the night sky with him, Sika Madu also possessed six seraph wings where in the air behind Yu he instantly decapitated him. Sika Madu comments only that it was another failure and he must start over from the beginning yet again as he watches them plummet to the ground.

Floating downwards he considers to himself that it will not do to leave the bodies here. Sika Madu is surprised to see that Ashera is still alive but wonders 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 he utters that pain is proof that he lives. Sika Madu can see that before Ashera died, some of Yu's blood dripped into his mouth, and that is was compatible. He finds it interesting and 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 considers having Ashera drink his blood. Continuing to speak to himself he asks if that is the correct answer, or is it unwise. Tossing Ashera to the ground he concludes 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 he asks Ashera what does he think, whether he wants his own or Yu's blood. Either way he says Ashera that he will never again be able to die. Asking the question in a different way Sika Madu questions whether Ashera has a reason to live on, if there is anything he feels he must do. He gets his answer from Ashera's eyes, deeming it good that his eyes say that he wishes to live and Sika Madu guesses that he will allow him to do so but in exchange he will have Ashera be of use to him. Sika Madu holds Yu's head over Ashera and allows the blood to drip into his mouth. He intently observes that it did not kill him and Ashera is indeed compatible before noting that he will have to look deeper into his bloodline.

Sika Madu does not wait for Ashera to regain consciousness instead he 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 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 he 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.

At some point, Sika then turns Krul Tepes into a vampire after finding her eventually, but he continues to take more interest in Ashera. More time passes before Sika decides to leave the vampire race for a distant land. With Urd Geales and Rígr Stafford as witnesses, he 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 leave, Sika comes up with Ashera's new demon name that would fit the language of the island: Asuramaru.

During his thousand-year disappearance, the First Progenitor soon became a demon himself known as Shikama Dōji, and would possess every head of the Hīragi Clan for generations. While possessing the current head of the family, Tenri Hīragi, Shikama Dōji 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, which is the reason Shinoa's older sister, Mahiru Hīragi, extracted Shikama Dōji from Shinoa when the latter was very young. This also made Shinoa completely forget about Shikama Dōji until he was returned to her later on.

Mahiru then takes Shikama Dōji into herself which, combined with her demon quickens Mahiru's 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, so Mahiru gave the demon to Guren to give to Shinoa.

While possessing Shinoa and Mahiru, he was also simultaneously possessing the Head of the Hiragi 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 Mahiru to the cross. Later that day, a vampire Mahiru uses Shikama Dōji to greatly increase her strength in her attack on Saitō.

On December 10th, Mahiru gives Shikama Dōji to Guren for him to deliver to Shinoa. On December 23rd, Guren gives Shikama Dōji to Shinoa, and Shinoa loses 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. He says Shinoa currently has little desire, but she will meet someone who will make her feel it in eight years.

Shinoa wakes up after ten hours of sleep and manifests Shikama Dōji to protect Norito Goshi from their assailants.

Events of 2020
Eight years after the apocalypse, Shikama Dōji first appears as a manifestation when Shinoa shows her Cursed Gear to Yu, and would continue to serve as Shinoa's weapon for Shinoa Squad and even when the squad defects from the Demon Army.

Osaka Arc
After Kureto Hīragi kills Tenri, Shikama is revealed to have also been possessing Tenri and every previous head of the Hīragi Family way before he came to possess Shinoa. Shikama declares Kureto the king of mankind, and asks what Tenri said about him. Upon hearing that he was described as an old god, Shikama laughs and says that God was more twisted than himself. Upon being stabbed by Raimeiki, Shikama greets the demon blade like an old friend before being slammed into a building. When Kureto tries to kill Shikama with Abaddon, Shikama commands Abaddon to cease its fire, and the demon stops. Shikama reveals that he is the reason for the Seraph of the End experiment, and even those won't be able to kill him. He then grabs Kureto and begins to possess him, introducing himself as the first vampire. However, Raimeiki is able to immediately halt Shikama's access to Kureto's heart, and though the angelic demon was stronger and was about to break through the thunder demon's guard, Shikama was sealed off (for now) because Raimeiki gained more strength from Kureto's greed.

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

Shibuya Arc
After arriving at Shibuya, when Guren, Shinya and Shinoa are allowed to enter to meet Kureto who is possessed by Shikama Doji. Shikama Doji stares at everyone in the room with a smile on his face.

When Kureto was attacking Guren, Mahiru-no-yo sees Shikama Doji floating behind Kureto and warn's Guren that he is being possessed by an unbelievably powerful monster describing Shikama. Later Shikama Doji manifests into his scythe form willingly, surprising Shinoa, later she talks with him in private inside her mind, and he appears in his scythe form instead of his actual appearance this time. When appearing behind Shinoa, he tells her he wont be able to show his true appearance anymore unless she opens her heart to him, which she refuses, saying he will possess her. Shikama explains that he is too busy possessing someone else.

Shikama Doji tempts her to lower her barriers against him and she should be fine no matter what though she denies it, he even propose to share some of his memories which those memories might save Kureto but she counter that her own life is more important. Shikama says she might be able to turn Mika back to human and the look on her beloved (Yu) happiness he further suggests a way to return Yu humanity to him, Shinoa's heart starts to pound louder, Shikama Dōji tells her that the demon and angel in Yu will eventually erode away his mind. When Shinoa tells him to stop and calls him a demon, Shikama Doji says he's not a demon and will reveal what he is if she lower her walls. He states she truly wants to save Yu and declares that he will eventually possess her instead of Kureto and affirms that there has never been a vessel of her caliber in all the generations he has possessed the Hiragi Family. Shinoa screams loudly to Shikama Doji to be quiet. After Kureto was handcuffed, Shikama Doji's shadow moves from Kureto to follow Yu and starts talking to Asuramaru in his sword form. Calling him Ashera as he enters Asuramaru's mind, he greets the purple haired demon with his original name, Ashera Tepes. Asuramaru asks about his identity. Shikama responds by claiming that Asuramaru isn't a demon, telling him it's time to remember him, when Asuramaru demands that he leave, he declines and Asuramaru fights him. Noticing and commenting about the current weapon Asuramaru is using, Shikama Doji says he is glad that he is doing well, as he summons numerous scythes. When Asuramaru fails to strike him, Asuramaru attacks him by affecting the space around him, though he lets his guard down when he is confused, mentioning that never someone entered his heart before.

Shikama Doji vanishes and reappears closer to Asuramaru, holding him in place and telling him it's time to remember who he was and what was done to him. As Shikama Doji uses his fangs and bites him to drink his blood, he struggles and he begs Yu for power but Shikama Doji says he won't allow him to borrow Yu's greed and forms a barrier around them. When Yu arrives he rushes to him but is unable to give his greed to Asuramaru. He summons his sword to him and Asuramaru returns to demon form manifested. Shikama Doji comments that watching them side-by-side together brings back memories and says it's been a long time since he last saw Yu. He starts a conversation talking to Yu and Asuramaru by asking if they are doing well since he hasn't seen them for a long time. Asuramaru warns Yu to ignore him, stating that his voice can spellbind others. Yu questions him if he knows his identity, Yu denies knowing him. Shikama Doji says neither of them have any memories of their past selves, then he tempts Yu with information about his past existence, and Yu falls into his desires as Shikama Doji subdues him. He moves to Yu to bite him saying Yu left open his heart because all he wants is to be loved and Asuramaru tries to rescue him from his grasp but fails, Shikama Doji tells Asuramaru to wait and he will take him as well. Yu, however, just pretended to fall under his control and gives him a comment that he was just kidding. It gives him the chance to injure Shikama Doji who is surprised and states that Yu is supposed to be another empty vessel. The two of them fight him, Yu and Asuramaru, seemingly killing him as he disappears into thin air, then they carefully dispose of his remains.

However, soon after, Shikama Doji suddenly appears unharmed, alive, and well, having waited till they dropped their guard. He tells both Asuramaru and Yu they are getting along well, much to his happiness, then he shoves his hand into Yu's and Asuramaru's chests, stating he has to kill the two of them now, as curse marks begin appear covering their face. Shinoa manages to enter Yu's mind by opening a pair of doors, saying she won't let him do it, she throws her scythe at Shikama Doji wounding him. He says this is the first real damage he has taken today, complementing her skills. Shikama Doji 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 shouldn't do. After sixteen years she has finally lowered her inner walls of her heart. He bids farewell to both Yu and Asuramaru stating that his goal for today is complete. [[File:Wounding Shikama Doji.png|thumb|220x220px|Shikama Dōji revealing the truth to Yu after Shinoa's rescue.

]] He appears behind Shinoa and grabs her by the neck. She struggles and start losing consciousness, but after a little encouragement from Yu, telling her to resist him, her strength increases, allowing her to continue resisting him which amuses Shikama Doji. However her resistance later proved to be useless. A door opens underneath him and he takes Shinoa with him, then the door closes, preventing Yu from rescuing Shinoa.

Shikama Doji is fully awakened, now possessing Shinoa's body, Ferid attacks Shinoa to prevent her from becoming a vampire but a scythe manifests and chains sprout from the scythe form, which cut Ferid"s abdomen bisecting him. They also cut off his left arm, with which he wields his sword. Crowley then grabs Ferid's head and throws him against the wall. The chains start to attack Crowley, who manages to defend himself with difficulty for a time, until his head is slashed off. Ferid starts asking Shinoa if she is the First Progenitor. She hints at this being a correct guess, and Ferid starts a conversation with the First Progenitor after reattaching his torso. Ferid questions the point of of this destroyed world, the endless, meaningless, human wars. He asks why vampire bodies won't die, even after substantial damage. He blames Shikama Doji for giving this 'Curse' to vampires, and for giving it to him. Shinoa asks Ferid, what would he do if he knew this information. Ferid responds that he will decide once he hears. However, the First Progenitor states that he is not the one who made him immortal. Ferid confirms, saying it was his father that 'Cursed' him and is the one that caused this ripple. Some time later a wounded Ferid comes out of the basement, telling Guren, Shinya, Kureto and Mika to run. Having seen him at Shinoa's mercy the First Progenitor decides to fight the group, summoning multiple scythes at 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 Doji summoned shower on Guren and Kureto whom they defend against whilst possessing Shinoa's body. As reports arrive that the Hyakuya Sect have arrived who the first aware that Rigr is behind it, Shinoa ceases her attack and smashes her way out the window. He later arrives where Mirai is being held as the Seraph of the End and is politely greeted by Saito who is also there. The first still in Shinoa's body) greets him as well saying it has been some time. The first ignores Mirai in between them and Kimizuki nearby to warmly ask Saito how many years it has been, and whether he has been well. Not reacting to Saito'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 hearing that the unification spell is ready. Shikama Doji finds the plot to restrain them as funny seeing the opposition as weaklings and asks if they can really do that. They pay attention to Basteya and their accomplice begin the ritual using spell tags.

With Saito 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. The first brushes off Saito's desire to test it on them by remarking how dull this is and states they will be on their way now. Reaching towards Mirai, the first has their arm wrapped tight with one of Saito's chains. They free themselves by cutting Saito's head off with a sweep of their hand.

With Kimizuki taking Mirai away at Saito's suggestion, Shikama Doji 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 Saito's head which is now connected to his body by a chain and floating in the air. asking what happened to his head. Shikama Doji does not recall constructing him like that then asks if they cut the chain would Saito die. The instant the first hears that this is the case, they do not hesitate to slice the neck chain. The result of this action is not the death of Saito but an abundance of chains bursting out in all directions which are guided to stab near the first. Shikama Doji runs to evade these, and annoyed, says that Saito did not die at aall and lied to them. Smashing their way through a window outside, Shinoa's body produces Shikama Doji's angelic wings to fly in the air. The chains are advancing outwards from the building and the first is confronted with chimera like beasts unleashed by Saito. Shikama Doji notes they seem dangerous, that 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 and disconcertingly announces that if Saito keeps interrupting them like this, then they will punish him. Asked by Saito if they finally manage to see him, the first can present a smile. With Saito directing his chains and his beasts to stab the first, they respond with their scythe, ordering the ones summoned to slice Saito to bits. The collision between the two powers causes multiple massive explosions around the area. Remaining calm, Shikama Doji's scythes clash with Saito'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 Doji notices that something has happened, sensing Noya's awakening, and questions Saito if it is his doing. The battle continues and aware that something happened, Shikama Doji questions Saito out of curiosity as to whether he arranged that. The first knows Saito 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 Saito. Preparing to launch an enormous scythe, the first has no intention of allowing Saito to use that trump card, whatever it is and says they are done now. Afterwards they notice Guren's arrival, then asks Saito if this demon is his trump card. Shikama Doji voices the intent to kill Guren, sending scythes at him before appearing taken aback at seeing them halted by Mahiru and Noya. They are further surprised noticing a sinful key in Guren's possession when he tosses it to Saito. Shikama Doji is confident that one key is not enough, but is interrupted by Saito 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. Shikama Doji adamantly states it is not nearly enough all the while blocking an attack from Guren. 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 Saito. The first then see's Guren, Mahiru and Noya acquire a sinful key each after Guren, along with Ferid using Jigenso, pulled off their own betrayal on Saito. The first is surrounded with a sinister power entrapping Shinoa.

Even with the power emitted from the sinful keys, Shikama Doji is confident he could certainly resist this if he chose to, but that would break Shinoa as his vessel. Conceding, he allows Guren and the others to seal him for the time being, and delivers a final laugh at Guren suggesting he make it an eternity.

Visualized, Shinoa considers that the demon army is Shikama Doji'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

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

He also possess great knowledge about seraphs, demons, vampires and humans having been experimenting for six hundred years trying over and over, killing hundreds of thousands of human guinea pigs. He knew that Ashera was a nobility, and knew how to save Ashera from dying. He was interested that Yu's blood is compatible with Ashera having turned him into a vampire. Sika Madu also has a large room filled with cylindrical glass tanks with a black substance, namely Dark substance/Matter, that has spherical appearance. It has yet to show it's abilities, though it has it's own will, such as a ball of it levitating above enthroned Yu, that can extend many tentacle like projections and make contact with Yu's head. He also managed to reattach Yu's head despite him being decapitated. In addition he keeps a corpse of a "Mikaela". According to Noya, Sika Madu has the ability to clone Yu's if one should die. Even after becoming a demon, Shikama Dōji hasn't forgotten any of his memories or the knowledge he has.

Demon
As stronger vampires make stronger demons, Sika Madu continues to be the most powerful being in existence as the demon, Shikama Dōji.
 * Demon's Thrall: He 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: Basic demon ability, but Shikama Dōji is able to somehow possess people simultaneously as he was able to be with Mahiru/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 stated that pretty much nothing, not even a Seraph, can kill him. Even after getting stabbed and electrocuted by Kureto, 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.
 * 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: Shikama Dōji is able to form a barrier and seal anyone in it away with him or prevent them from escaping, as shown 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 means to attack.
 * Miniature Form: A black pen-length rod that is more convenient to carry.
 * Perception: Shikama Dōji can detect anything that comes within the radius of his scythe.
 * Manifestation: At Shinoa's orders, he can manifest into a large smoky creature that will attack whoever she chooses. It is shown he can manifest on his own will to scythe form if he wants to as he did in Shinoa's hand.
 * Scythe proficiency: Shikama Dōji is very expert in using scythes, he can materialize numerous scythes and attack from wide radius. In Shinoa's body he can also use them to levitate scythes for barrage attacks as well, in addition he can summon numerous ethereal scythes and whirls them rapidly making them as they are circle similar to a halo appearance of scythes as his most deadliest attack. Additionally he can manifest endless amount of scythes.

Scientific/Occult Abilities
Although unknown which is which, its been stated and implied by the oldest of the Vampires,Progenitors, Urd Geales, Rigr Stafford, Ashera Tepes, Krul Tepes and Noya Hienma that Sika Madu during his days as First Progenitor, frequently dabbled and experimented on the supernatural using both what appears to be scientific and magical methods with varying results.

Human Creation
As seen during the memories of the Three Third Progenitors and confirmed by Noya Hienma, Sika had successfully created what they called his "human creation technique". Where he successfully created a machine or method to mass produce Yūichirō Hyakuya Clones as an everlasting supply of test subjects for his Seraph Experiments.

This is seen where it was implied that Sika had created, raised and killed over hundreds and thousand's of Yu's clones during his experiments to see if he could create a stable seraph. Noya himself state that Sika had created so many that he probably won't notice if one or two of them were killed by him.

Although the exact method 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. With several of the Yu's having been shown to have very shallow, almost robotic personalities and they were stated to be too unstable that they usually died before they fully grew into maturity.

however by the time of the 21st Century, it was stated by Noya that that Sika had already likely perfected the method due seeing to the fully functioning and mature,Yūichirō Hyakuya.

Seraph Experiments
It was also apparent that Sika Madu also possess the knowledge and researched and completed the method to either create or summon the Trumpet of the Apocalypse and placing it inside a human host.

As seen where he was stated to have been running hundreds of tests and experiments in order to create a complete,perfect Seraph and was seen to have repeatedly placed them inside his Yu Clones.

Vampiric Experiments
As stated during his reunion and battle against Saitō, Sika was implied to have engineered and done some changes to his body as a vampire. As seen where he stated that he remembered all the features, powers and capabilities he placed into Saito's body.
