The Light Which Remains

"The Light Which Remains" (残ったヒカリ) is the one hundred and thirtieth chapter of the Seraph of the End: Vampire Reign manga series, written by Takaya Kagami and illustrated by Yamato Yamamoto.

Synopsis
Yu remembers he is Mikaela, yet wonders who Mika is. Saito views humans being created in Shikama Doji's memories. The angel spirits in humans did not recollect their prior lives. From what he has seen, Saito is angered that the First has been fighting alone all this time.

The dark-haired youth had the spirit of Mikaela inside him. Whispering to Yu the homunculus, Mikaela formed his own plan to save everyone without Sika Madu knowing. Connecting their souls and switching places, the spirit of Mikaela inside the human boy will become Yu completely. Yu the homunculus will pretend to be Mikaela in his place. Consequently Sika Madu will never be able to resurrect Mikaela as his soul will really be in the human he is inhabiting. Mikaela erased his own memories, while the homunculus entered his physical body to scatter the seven lights to make his potential resurrection all the harder. Sika Madu caught one of the lights, a sinful key.

Presently, Yu and Mika discuss their purpose given what they have learned. Additionally, Yu has noticed Mika is turning into a full demon. Affirming the them they saw in the past is not really who they are, Yu's focus is not giving up on Mika. Helping Akane, Guren and others remains the priority. Now feeling they can create their own rules, Yu and Mika mean to gain the seven sinful keys.

Eight years prior, Ferid wondered what the Mikaela the First wanted was. Yu and Mika had been brought to the underground vampire city. Ferid joined Guren in the room where they were to look into their memories.

Summary
By daybreak over Mt. Fuji, within the cabin Yu speaks aloud how he is Mikaela. As Mika appears to join him, Yu gives some thought to their situation. With what they have learned Yu asks who he is, to which Mika remains silent.

In Shibuya, the Capital of the Imperial Demon Army remains in the control of the vampire progenitors. Saito is within a prison where Shikama Doji is nailed to the floor with his finger in the First's head. Outside the cage, Urd observes. Closing his eyes, Saito is viewing memories of the first humans seen on Earth being produced by the homunculus named Yu. The light spirits of the deceased angels are seen rising from their graves and enveloping the human children.

Stationed in the memory witnessing this, Saito considers if this is true then Shikama Doji has spent all these eons fighting by himself. At the time of the memory, Sika Madu was present when two children were dropped into the world by the homunculus. As each registered what where new surroundings for them, they had angel spirits fly into them.

For the first time Sika Madu paid attention to these two children who were affected by the angel spirits. Chuckling, Sika Madu found one of the children asking who he was. Regarding him, Sika Madu then found they headed off to go see the others. The other child was happy to go as well. As Sika Madu thought, they do not remember their lives as angels. Feeling that was for the better, Sika Madu affirmed it was better they didn't.

Close to Sika Madu from the scene, Saito appears angered before speaking to the unresponsive memory how he is still fighting for them even now. As the past scenario plays out, Sika Madu spoke how without their memories the angels might be able to find happiness in this Hell, before adding how human lives are short.

While Saito speaks how the First has been here struggling, Sika Madu at the time commented how his plan did not have a high chance of success. Moved to shouting, Saito is angry at the idea that Shikama Doji has been involved in this all by himself the whole time. Looking to something, Sika Madu said how he was not going to give up on everything and that he will resurrect them all.

Having realized the situation, Saito finds tears down his face. Shocked, Saito does not remember any of this but sees he is crying. Wondering why, Saito contemplates does he still have his angel memories stored somewhere.

The homunculus was focusing on Sika Madu who was communicating something then. In response to one of the children, both Saito in the memory, and Sika Madu at the time reacted to the sound. A child with dark hair was before the coffin containing Mikaela's corpse and Sika Madu questioned what he was doing there.

Jolted, the child, unknown to Sika Madu, had the spirit of Mikaela conscious in the possessed body. Staying put, Mikaela in the human child's body spoke as discreetly as he could for Yu the homunculus to come here quietly. Positioned near to Sika Madu and remaining there, the homunculus obliged with Mikaela's wish and broke off a globule of itself. This separated part travelled over to where the youth was positioned.

The small parting of the homunculus opened an eye before the figure, behaving as if it knew this is Mikaela in front of him. Mikaela in the human boy's body spoke at once how father was really smart, if he found out that he is Mika then he would instantly try to protect him no matter what. Accordingly, Mikaela determined he could not get his plan to work if he is stuck getting coddled.

After the homunculus acknowledged what was intended, Mikaela asked Yu what should they do. Affirming that they would have to lie to ensure Sika Madu did not find out, Mikaela detailed that to be extra sure he needed to find someone else to be "Mika" in his place.

As the homunculus processed what he might mean, Mika in the human boy's expression confirmed the intent. Startled at the idea that it was to become Mika as part of this plan, the homunculus conveyed its response. Answering that is not what it said before, Mikaela raised how it promised to stay with him and protect him for its whole life. Mikaela questioned whether the homunculus was just going to abandon him.

Considering it, the homunculus used its body to answer no. Ever in the human boy's body, Mikaela spoke how the homunculus would never abandon him and that they were best friends. Using its body for a nodding motion, the homunculus agreed with Mikaela.

Saying for them to do this together, Mikaela said they would connect their souls together. Yu the homunculus and Mika would become one. A shadowy tendril from the homunculus connected with the finger of the child which Mikaela's spirit was occupying. Judging that this would be super hard though, Mikaela considered that they would have to go against father. Addressing that he was really smart, Mikaela felt he and the homunculus had to get serious if they were going to get the better of him.

Next, Mikaela elected to forget that he was himself. Meaning to become "Yu" completely, he spoke for the homunculus to do the same. Guiding the homunculus to forget everything as of now, after a pause, Mikaela spoke that the homunculus was Mikaela. The plan was as long as the homunculus was a convincing Mikaela, father would never succeed in resurrecting the real him not when his soul was really in the human body.

Intending for them to get this fight started, Mikaela changed from calling the homunculus Yu, to Mika instead since that was what it was meant to be. No matter how many eons it takes, or how many generations they go through, Mikaela in the human's body felt in the end they would save everybody. It would be just the two of them as a team, and Mikaela asked the homunculus would it stick with him. After the homunculus responded affirmatively, the human boy with Mikaela's spirit conscious there laughed with delight.

Now fully addressing the homunculus as Mika, the actual Mikaela stated for the homunculus to jump into his body of which the corpse lay in the coffin nearby. Mikaela directed the homunculus to take the seven lights inside his physical body and send them flying far out into the world where father could not reach them. That way it would be even longer before he could try to resurrect him. The homunculus appeared ready to proceed.

From his perspective, Sika Madu was observing a human boy in front of the coffin of Mikaela so asked what he was doing. Where unknown to him it was Mikaela's spirit conscious in the human child, Mikaela paid no mind to being spoken to by Sika Madu and instead invoked light around his finger. Placing his finger to the youth's head, Mikaela spoke to erase his memories and reiterated that he was Yu to instill that cover identity.

Meanwhile, the small part of the homunculus that was interacting with Mikaela entered his deceased physical body in the coffin. The corpse of Mikaela opened its eyes, and rose from the coffin with his wings outstretched as the homunculus inside had it do.

Shocked at this sight, Sika Madu shouted to get away. The spirit of Mikaela in the human boy's body kept his light enveloped finger to his temple. Speaking to the homunculus as Mika as per its assumed identity, Mikaela bid it farewell. Even if he forgets everything, even if he dies countless times, Mikaela promised that he would collect all of it.

The homunculus within the corpse of Mikaela was able to speak aloud that it was a promise. Before finishing by referring to the spirit inside the human boy's body as Mika, the homunculus inside Mikaela's physical body changed to bidding him farewell as Yu. Radiating a light, the homunculus animating Mikaela's physical body shot out seven streaks of light that were all fired out in different directions.

Shocked at this display, Sika Madu leapt upwards and was able to seize one of the lights. Pained at how hot it was, upon landing Sika Madu found he had caught a small cross-shaped dagger. Turning to Yu the homunculus of which its separate larger self was nearby ejecting a human and behaving normally, Sika Madu questioned what did it do.

Where the homunculus responded quizzically, Sika Madu thought to himself how it would not understand. Having created the homunculus, Sika Madu felt it had no free will. Then thinking what was that, Sika Madu was unsure what happened. For everyone else in the vicinity, Sika Madu felt he should be the only one here with any independent will.

Speaking to the child with dark hair that Mikaela had erased his memories in, Sika Madu questioned what was that, and what did he do. Confused at being spoken to, the youth appeared unable to answer. Before waiting for a fuller response, Sika Madu ordered the child to show him his memories.

In jabbing his finger into his head, the youth coughed up some blood. Shocked in saying nothing, Sika Madu found there were no memories at all. After the child fell, Sika Madu coldly remarked it died just like that. He added human bodies truly were horribly fragile.

Placing his hand on the deceased child, Sika Madu wondered if this was also his punishment. The way forward was rockier than he anticipated. What Sika Madu referred to as human dolls could barely survive a mere hundred years. Wondering how much darkness could they gather in that short time, Sika Madu also questioned how many repetitions would it take. He concluded this would be a long battle.

Going about its business, the homunculus ejected another human child. Alone, the child commented weird, for some reason they had this feeling that there was something they needed to do.

In the present day within the cabin, Yu speaks how now he gets it. Starting to remember, Yu states this means that he found Mika. Happily responding that he got found, Mika adds it sure took him long enough. Replying that he did not have any of his memories, Yu wonders if Mika does. Answering he has none of his either, Mika feels if he did then he would not have been able to bear it. Since this has all taken so long he would have given into despair.

Mentioning how the vampires all live for a really long time, Yu comments they seem to hate it. Agreeing, Mika states that Krul looks like she has suffered a lot. Krul herself is remembered, apparently within Sanguinem.

Asking Mika what it means to live then, Yu voices they are all just going to die anyway, then forget. Wondering where is the point to living, Yu additionally questions why bother bringing everyone back to life. Yu also asks why he is trying so hard to turn Mika back into a human.

Addressing whether he is really bringing that up now, Mika adds he already gave his answer to that. After Yu asks what was it again, Mika replies it was for them to run away together somewhere. They would go into hiding, live a quiet peaceful life, then die together. For this, no matter which way Mika looked at things it was the only viable answer he could find.

Reminded of the running away thing, Yu mentions Mika said he could not change anything no matter how hard he worked, so wonders why bother working at all. Where Mika does not have an answer, Yu raises how even if he did run away somewhere and die quietly would that make Mika happy. Considering it, Mika guesses it would. Tying it into how he cannot hold out for much longer, Yu breaches the topic of how at the rate things are going that Mika will turn into a full demon.

When Mika addresses how he noticed, Yu confirms he did. Yu asks Mika what will happen when he is a full demon, would he possess him or try to leave. After Yu bets he would just try to leave, Mika appears impressed that he noticed that too.

Yu pointedly asks Mika if he thinks he will let that happen. Giving it some thought, Mika details how Akane and the kids are still dead too. Questioning if they can really give up, Mika raises if they can say they are done and walk. It is recalled how as children Yu and Mika witnessed Ferid striking the head off one member of their orphanage family when he was in the process of murdering them all.

Mika contemplates the matter, before Yu speaks how in the end the only thing they can say is that they do not remember clearly. For what they viewed in the memories they entered, Yu states the them they saw way back then is not really the them they are. Where Mika agrees with it, Yu continues that they are who they are now and that is it. After Yu affirms he is not going to give up on him, Mika thinks about his words.

Not wanting to give up on Akane and the kids either, Yu additionally wants to save Guren and the others from what they are suffering under too. In response to Mika asking if there is something else, Yu acknowledges whether that is kind of a lot. He does not get what happened to the old them, or what goes on after they die and all that, but Yu feels if the them they are today die then they are dead.

Where Mika feels that is true, Yu declares they cannot afford to die. Mika sarcastically thanks him for confirming the obvious. Fired up, Yu summarizes that basically they now know that this is a super hard game where they have to fight angel bosses and god bosses. Framing it as that they are just weak humans who keel over and die like nothing, Yu continues that despite that they are still going to find some way to make it work and win.

After Yu asks him if that is right, Mika's summary is basically that they have to try hard, the end. All that talking, and Yu just circled back to the same conclusion. Acknowledging that, Yu adds they went to the past looking for information to help them win, not to get away which Mika feels is true.

Beaming at him, Yu announces to Mika that he is not letting him get away until they die. Regarding his face, Mika guesses so. Turning to what they are to do, Yu reasons now they know the rules of the game. If they know the game, they can make rules. Although Mika is none too keen on the game, Yu explains they are not players anymore, they are the game designers.

Once Yu rouses him with the question on who is going to win in the end, Mika grins broadly that they are, who else. Matching the enthusiasm, Yu proclaims for them to do this. Yu and Mika intend to get the seven sinful keys and they will do whatever it takes to do it.

Eight years prior in the underground vampire city of Sanguinem, Ferid was strolling along humming to himself. Thinking how the First wants to make a Mikaela, he wondered what that was. Ferid also thought who is it if the First could not become it. Contemplating how he was not compatible either, Ferid was unsure what in the world this Mikaela was.

Making his way down a corridor, Ferid was informed by a cloaked vampire that the humans' delivery arrived. Responding that it was good, Ferid announced now he could rifle through their memories. Questioning where they had put it, the vampire responded the second guest room. Thanking him, Ferid swept past the vampire whilst cutting their head off.

Turning into a new section of the corridor, another vampire was awaiting. As Ferid spoke for the kids, the vampire updated him that they have been drugged and were sleeping. Also thanking that vampire, Ferid similarly struck them down with a gout of blood left in his wake.

Entering through two large double doors, Ferid found a large spacious bed featuring drapes in the room. The figures visible were both Mika and Yu who were sleeping together back to back. Commenting how they were sound asleep, Ferid remarked what little cuties.

Having noticed someone else in the room, Ferid queried whether they had looked into Yu and Mika's memories. The other figure was Guren, who answered Ferid that he was just about to.

- Yu articulates a crisis of purpose to Mika after the memories of the past they saw.

"Are you really bringing that up now? Besides, I already gave you my answer to that."

- Mika has a calmer approach in addressing Yu's concerns, namely the one of turning him back into a human.

"Let's both run away somewhere. We'll go into hiding. Live a quiet, peaceful life. Then we'll die together. No matter which way I looked at things, that was the only viable answer I could find."

- Mika reflects on what his answer was for his and Yu's problems, where that was a priority and being turned back into a human wasn't.

"Oh yeah. That running away thing. You said I can't change anything, no matter how hard I work. So why bother working at all? Heck, even if I did run away somewhere and die quietly... Would that make you happy?"

- Yu's questions for Mika, of which the second is in the context of that being preferable for Mika as Yu would be safe where Mika is becoming more of a full demon.

"You can't hold for much longer though, right? The rate things are going, you'll turn into a full demon. (Mika raises how he noticed, to which Yu replies) I noticed. What'll happen when you're a full demon? Will you possess me? Or will you try to leave?"

- Yu addresses a matter and questions what Mika intends to do, where he bets on the latter option.

"You think I'll let that happen?"

- Yu's determined response on whether Mika thinks he will let him leave by himself and endure his demon state alone.

"Hmm... Akane and the kids are still dead too. Can you really just give up? Say we're done and walk?"

- Mika's rhetorical question in considering their options when Yu raises him possibly leaving rather than become a full demon and risk possessing Yu.

"In the end... The only thing we can say is we don't remember clearly. The "us" we saw way back then... ...Isn't really "us." We're who we are now. That's it."

- Yu shares his position which Mika agrees with that they should not settle on the prospect that they are the Mikaela angel and Yu homunculus of the past, rather decide to be themselves as they are.

"I'm not giving up on you."

- Yu's existential and purpose worries are cast aside when he reminds Mika he is his priority.

"I'm not giving up on Akane and the kids, either. I wanna save Guren and the others from what they're suffering under too."

- Yu re-commits to helping others.

"Isn't that, y'know, kind of a lot? I don't get what happened to the old us, or what goes on after we die and all that... But if the "us" we are today die, we're dead. So we can't afford to die!"

- Yu roused from questioning what the point to living or anything is, to determinedly moving forward as he and Mika are.

"And we're just weak humans who keel over and die like nothing. But despite that we're still gonna find some way to make it work and win!"

- Yu's resolve to prevail never mind what they are.

"Well, yeah. We went to the past looking for info to help us win, not to get away! I'm not letting you get away until we die!"

- Yu speaking to Mika on why they accessed memories, and his way of saying they are to remain together.

"So! Now we know the rules of the game. If we know the game, we can make rules."

- Yu feeling he and Mika are not players anymore rather can shape the rules of the game they are in.

"Us, of course! Who else?"

- Mika's affirmation to Yu that they are going to win.

"Right?! Let's do this! We're gonna get the seven sinful keys! And we'll do whatever it takes to do it!"

- Yu having agreed with Mika on their path forward.

"Hm-Hmm! ♪ Hmm de-doo! ♪ The First wants to make a Mikaela. What is that, I wonder. Who is it... If the First couldn't become it? I wasn't "compatible" either. So what in the world is this Mikaela?"

- Ferid strolled through Sanguinem, his humming turning to thoughts at the time concerning what Mikaela even was.

"Good! Now I can rifle through their memories. Where'd they put it?"

- Ferid having been informed the humans' delivery had arrived, which was Yu and Mika.

"Aww, they're sound asleep. What little cuties. So? Have you looked into their memories?"

- Ferid comes across Yu and Mika, and has a question for Guren who was also awaiting in the room.

Cover Details
The feature image for chapter 130 concerns in-universe story events. The panels on the right side concern the outside of the cabin that Yu and Mika had taken up base in. Of the four panels that make up the page, Mt. Fuji in the distance and the Sea of Trees (Aokigahara) are in the very first one where it is now day time. Yu in his kneeling position with the view on his back is a similar scene to the final page of the previous chapter 129.

As Yu processes what he has learned from the past, in the third panel the cabin is also shown. For the time absorbing the details, the final fourth panel features speech bubbles as Yu speaks that he is Mikaela. This is related to what Yu saw in a memory from the prehistoric past which showed the spirit of Mikaela entering the body of a human boy who looked like him. Yu is remembering he has Mikaela's memories as the spirit conscious there, and not the memories of that particular human.

For the lettering, the Seraph of the End logo and authorship details are in the top left of the second panel. The chapter number and title are in the opposite corner in the lower right of the third panel.


 * Mika returns to the physical world for the first time since entering the memories in Chapter 122: "Calories for Travel." Where Yu had to return his consciousness to his body to eat in order to regain energy, Mika was tasked with keeping track of events in the memories they were accessing in case anything were missed.
 * Having assumed but not fully entertaining that the past Mikaela was Mika due to their resemblance, and Yu being the homunculus on account of the name, Yu has memories that he himself is Mikaela yet he does not assume that therefore Mika must be the homunculus in asking who he is.
 * The city of Shibuya is seen for the first time since chapter 122, along with Saito, Urd, and Shikama Doji's physical self.
 * Unseen but likely in the vicinity would be Lest Karr, along with Ky Luc, and Basteya Irclu among multiple Hyakuya Sect members.
 * Shibuya is described in out of universe text (the descriptive heading above a panel) as the capital of the Imperial Demon Army. With Kureto and Shinya's capture by Urd in chapter 106: "I Am Your..." and in particular Chapter 121: "Last Dawn" where the vampire progenitors effectively announced their control over the city, in practice Shibuya is a conquered city of the vampires.
 * Physically, Shikama Doji remains nailed to the base of the prison he was kept in where he has remained in that state since chapter 117: "Of Monsters and Demons".
 * Placing a finger into the head appears to be the means that a vampire such as Saito can access the First's memories. Later, Sika Madu would also do this when trying to access a human's memories which result in the murder of that human. From Shikama Doji's discomfort it appears this is not a demon's means of accessing memories in which contact is harmless, rather his skull has been broken into.
 * Accessing memories is a demon based trait, Saito is the first vampire seen able to enter a memory. In chapter 116: "Brother and Sister" Krul could materialize somewhat in Asuramaru's realm, without any apparent technology, so vampires have some means of engaging with demons.
 * The memories that Saito is seen viewing are that of the homunculus bringing the first humans into the world with the angel spirits entering them. From his comments on Sika Madu spending eons fighting by himself it can be inferred he witnessed what Yu and Mika did namely other memories such as the seraph civilization being destroyed along with the human-appearing angels.
 * Angel spirits were seen flying into human children in the previous chapter, where this one confirms that the angel spirits are in control of these host bodies, however they have no memories of their previous lives.
 * Sika Madu knew enough about a transferring angel spirits to human bodies to suspect they would not remember their lives as angels. It may be the case he was familiar with the theoretical process, but this was the first time enacting it where he had his suspicion confirmed.
 * That the angels do not remember their prior lives is something Sika Madu feels is good, where he anticipates they may find happiness as short-lived humans.
 * Having before been angered that Shikama Doji had left vampires without purpose, Saito is at his most furious at the thought that the First has been enduring what he has by himself.
 * Even with Yu and Mika in the memory, where the homunculus was able to see them accessing it from the future in chapter 125: "Soft Serve with Father", Shikama Doji has made no indication that he is being watched. What may be an only case here is when Sika Madu in the memory turns to face Saito after he has shouted, and says that he does not mean to give up on everyone and will resurrect them. By chance Sika Madu have been looking in that direction as he spoke aloud at that time, or Shikama Doji in the present may have entered that section of the memory to relay what is a noble intent to Saito before him.
 * Regarding the angel spirits in human bodies in which they have no memories of their past lives, Sika Madu comments on resurrecting them. From this, Sika Madu means for the angels to be resurrected as they are, not live on as humans where they could be alive in that sense.
 * Tears flow down Saito's face after learning what Shikama Doji has experienced, which he considers is a link to his angel self, all the more particular since vampires do not generally feel emotions.
 * For the link between angels and vampires, Saito is prepared to accept that he may have angel memories he is just unable to access.
 * While Sika Madu seemed able to sense angel spirits within humans, he has no idea that the spirit of Mikaela has entered one.
 * Having successfully had his spirit enter the body of the child he spoke with, Mikaela kept his presence hidden from Sika Madu.
 * The homunculus could hear Mikaela speaking from within the body of the human child where Sika Madu apparently couldn't.
 * A new capability of the homunculus is shown where it can break off a small orb of itself to travel over and interact with Mikaela in the human child's body.
 * Having made no indication of a plan previously, it was perhaps during the millennia that Sika Madu burned on Earth that Mikaela had formed one of his own. It is not one that involves Sika Madu, he has his own formed out of the idea that he would be coddled and so unable to carry it out if Sika Madu knew he was conscious.
 * Given the homunculus' willingness to go along with everything Mikaela suggests, where it mentions nothing to Sika Madu that his son is alive, the homunculus appears far more in sync with Mikaela that the individual who made it.
 * Non-verbal communications were used by the homunculus previously, yet this is the first instance of it producing verbal sounds, namely a "hyoop" noise. What the one word is communicating each time it is used for different circumstances is understood by Mikaela.
 * Mikaela's plan to outsmart his father is to have Yu the homunculus become Mika in his place, that way Sika Madu would never succeed in resurrecting him as his soul would be in the human body. For his plan, Mikaela did not want himself resurrected and was prepared to wait eons for his goal of saving everyone.
 * Sika Madu's plan of resurrection concerns using the light gathered inside Mikaela, although Mikaela himself seems confident in an unrevealed different means of resurrection.
 * The homunculus appeared surprised that it was the one in mind to become Mikaela, though it may be the case it was something discussed before where just now the plan was for certainly going ahead.
 * At some unknown point, the homunculus had promised Mikaela that it would stay with him and protect him for its whole life in an indication of what they have discussed on a personal level.
 * From Mikaela's comment it would appear that homunculus' have life spans. In chapter 128: "The Wings of Icarus" the homunculus was seen being destroyed however it could be regenerated. While able to be reformed, and indestructible in this sense, there may be a time limit of its overall lifespan. Alternatively if immortal, the homunculus promising to protect for its whole life may have meant forever.
 * For what the entities body is made of, the homunculus may be capable of sweating if this were not an indication of its surprise having learned something foreboding.
 * In voicing "Hyooie" once while surprised the homunculus has a second word in its lexicon including the "Hyoop" sound.
 * Whatever the homunculus said in expressing unease at assuming Mikaela's form it surely included sentiments at being apart from him, from Mikaela stating that the homunculus promised to stay with him and protect him his while life.
 * Moving its body to either side for a no, and up and down in a nodding motion allows the homunculus to physically answer questions.
 * Although meaning for them to be different individuals, Mikaela's method of enacting this is apparently to connect his soul with the homunculus for Yu (the homunculus) and Mika (Mikaela's shortened name) to become one.
 * It would appear that homunculus' or at least the one named Yu has a soul from Mikaela's comment.
 * The homunculus can extend a shadowy tendril from its detached second self to seemingly form this connection with another soul.
 * Taking into account how smart Sika Madu is, Mikaela opted to erase his own memories. Intelligence or guessing would not factor into memories being accessed, Sika Madu was able to view them by placing his finger into a subject's head though it is unclear whether Mikaela knew of this capability. Either way by erasing his memories, Mikaela left nothing for Sika Madu to see at any rate.
 * Like Mikaela, the homunculus was to erase its memories and become Mikaela in his place.
 * It's not known if Mikaela was able to erase a homunculus' memories, or if the being was capable of doing it of its own accord.
 * Referring to it as a fight, Mikaela involved only the homunculus in a campaign of saving everyone, but exactly how was left unsaid.
 * Aware through some means that there were seven lights (Sika Madu had gathered light from the Tower of Babel and stored it within Mikaela) inside him, Mikaela directed the homunculus to scatter them to extend the time before he could be resurrected.
 * Sika Madu was planning to have humans gather darkness to resurrect Mikaela then access the seven lights inside him for resurrecting the fallen angels. Mikaela has had the homunculus bring out the seven lights itself, something Sika Madu did not seem to realize was a possibility. While Mikaela meant for this to increase the time it took for Sika Madu to resurrect him, he may have made it shorter. It would depend if it were faster for Sika Madu to have humans incrementally gather darkness over time to resurrect Mikaela and access the keys, or scour the world for the locations they had been sent.
 * Although ostensibly completely loyal and extremely helpful to Sika Madu, which it was, the homunculus neglected to inform him it could access the lights inside Mikaela. Neither did it tell him Mikaela's spirit was right there. Indeed, immediately from the start it was tasked with keeping an eye on Mikaela, yet had enjoyed itself with him playing hide-and-seek outside the seraph civilization in chapter 123: "An Ancient Game of Tag". The homunculus serves Sika Madu faithfully and effectively, and yet is simply more closer to Mikaela.
 * In erasing his own memories, Mikaela uses a light based power that radiated from his forefinger. Placed near his temple, Mikaela spoke for his memories to be erased and that he was Yu which seems to process to erasing memories in his spiritual self since he was in the body of a human at the time.
 * The smaller detached form of the homunculus is able to enter Mikaela's physical deceased corpse by floating down into it with no breakage to the skin in a manner similar to possession. True to that, the homunculus could make it appear as if Mikaela had come back to life in raising himself out of the coffin.
 * In rising from the coffin it would appear that the homunculus in Mikaela's deceased body had shattered the glass.
 * Upon seeing Mikaela erupt out his coffin, Sika Madu did not have any words for him rather told who he saw as a human child to get away from it. Alternatively he may have spoken to Mikaela to get away from the child as he perhaps did not want the risk of Mikaela's spirit entering a human body. Confusion took over from what Sika Madu meant to say, but in any case it does not appear he thought he was looking at Mikaela raising from the dead.
 * In promising to collect all of it, it's possible that the homunculus had broken off sections of itself and fused with each light in order to transport it to other parts of the world. The homunculus had taken each sinful key to delay the time Sika Madu could find them, where Mikaela, part of his plan or not, meant to find the pieces and collect the homunculus whole at a later date.
 * Shown to be capable of making vocal based sounds, the homunculus displayed its intelligence in the fluid sentence it first spoke as Mikaela who it was possessing. The homunculus had the intelligence, but not the physical capacity in its orbs like body to relay words it was capable of thinking.
 * Seven lights were blasted off in different directions from Mikaela's light enveloped body, which matches the number of sinful keys in later ages.
 * Remaining surprised, Sika Madu reacted fast enough to think to and seize one of the lights emitted.
 * At being cast off, the light was blistering enough to cause Sika Madu to respond with pain at how hot it was, which was a comment from someone who could endure a combined seraph lightning strike. It stands to reason the keys would be hot if combined they held enough light to resurrect every deceased angel. The seven keys appear to hold a similar amount of light as that of the Tower of Babel. Such a burning light may be what the God residing on the Sun is fond of since it was being gathered for that. For the keys themselves the heat seems to be fleeting, where the utensil was fizzling yet cool enough to be gripped by Sika Madu. Additionally humans of later ages could hold sinful keys so the heat given off them is just from the initial casting off of them.
 * The seven keys that Sika Madu said Mikaela held in chapter 128 were reminiscent of the seraph related artefacts called sinful keys of later ages both in name, connection, and number. This chapter confirms the lights mentioned are indeed sinful keys, the lights take the form of the cross-shaped daggers which became that seemingly automatically.
 * Presumably viewing this, Saito would perhaps realize the background to the utensil that blew his body apart in chapter 84: "Nativity of a Princess" after Ferid stabbed him with a sinful key and brought an end to his campaign to seal the First. For all his defeat then, Saito would wind up with the First captured anyway with help from Urd after he expressed curiosity in how far his plan had come along in chapter 106: "I Am Your..." where he could reach this point.
 * As a separate part of the homunculus was interacting with Mikaela inside the human boy's body, the other full sized part was apparently resuming its business of bringing humans to the world nearby to Sika Madu as it maintained its cover.
 * Notably, where human children with hair are not often made, one resembling the child who looks like Yu is dropped into the world just after the keys in Mikaela had been expelled, and Mikaela's spirit had erased his memories. Unclear what the significance of this brief moment, if any, is, the physically similar child may be a new body for the memoryless Mikaela to enter having left the human he was possessing. It may have just been a coincidental case of another physically similar human being made.
 * After seeing Mikaela rise and break into lights where a sinful key was caught, Sika Madu's first reaction is to turn to Yu the homunculus and ask what it did. Even though the homunculus was seemingly occupied with producing children, Sika Madu assumed it could have been the only one capable of being involved with what transpired.
 * His suspicions were brief however, Sika Madu then considered that the homunculus would not understand his question. Additionally Sika Madu would think the homunculus has no free will. Probably wrong on the first count, it is more than likely the homunculus understood what Sika Madu said, though Sika Madu would not be aware that it was able and willing of withholding information from him. Sika Madu would certainly be wrong on the second count, the homunculus capable of free will was also enacting plans with Mikaela without his knowledge of that either. The homunculus may not have understood the question at that point had it erased its memories as Mikaela directed. Another possibility is that the homunculus had passed the part of itself containing Mikaela's plan to a human body. The homunculus can split parts of its body, it would not be outlandish if it were capable of splitting memories.
 * For what the homunculus does share, it uses uses the "Hyoop" verbal communication, a perplexed one when answering Sika Madu.
 * It is revealed that Sika Madu made the homunculus that would be named Yu by Mikaela.
 * From this, homunculus' are created beings.
 * From seeing Mikaela break into lights and catching one, Sika Madu is not sure what happened evidently not having experienced this before. Where Mikaela was aware of this, he had accessed or gained knowledge through some means that Sika Madu hadn't.
 * For the homunculus and many human children with angel spirits inside them, Sika Madu felt he should be the only one here with any independent will. This may indicate that although the angel spirits are conscious inside their human bodies yet they have no memories of their previous lives, they may not have free will as they are. What Sika Madu considers free will is debatable as both the human children before and after they had angel spirits in them made what seemed their own decisions. It is also possible that Sika Madu was incorrect in his thinking, he certainly was given that unknown to him that the homunculus named Yu perhaps uniquely given its species displayed a great degree of free will. Additionally, Sika Madu had no idea that Mikaela's spirit was conscious and also displayed free will. It is very unlikely that Sika Madu was pretending to be unaware of Mikaela and the homunculus' actions on account that it is his thoughts considering the matter, thus not a display for those accessing a memory such as Saito to view.
 * The human boy with an angel spirit within him who first spoke to Mikaela appears confused at Sika Madu speaking to him. This would not be Mikaela's spirit inside the boy feigning confusion because he wants to keep his plans secret from Sika Madu since he has erased his memories. Accordingly the boy may still have Mikaela's spirit inside him, though he has just forgotten his true identity. Alternatively Mikaela's spirit may have left (perhaps transferred to the almost identical appearing other youth dropped from the homunculus) where it was the youth returned to himself.
 * This youth, the original human boy before being possessed and first human seen on Earth, him with Mikaela's spirit inside without memories or not, was murdered by Sika Madu in a botched attempt at accessing memories.
 * From the memories accessed, Sika Madu was surprised to find none at all. The youth was either Mikaela with his memories erased, or the youth whose mind was also wiped along with Mikaela's as an effect of him using the memory erasing power on the head of the body he was in.
 * With the human boy being murdered, Mikaela's spirit would evidently pass to other beings where having erased his memories he would believe himself to be Yu should memories ever be stirred. As stated, another Yu like individual had just been formed before the child's murder, and so Mikaela's spirit may have already been transferred previously, or perhaps then.
 * After murdering one, Sika Madu commented that human bodies are horribly fragile which may indicate he had not yet began to murder them at the rate he would in later ages where he would come to regard them as test subjects.
 * In contemplating how fragile humans are, Sika Madu wondered if this was part of his punishment where he may still think he is being punished after a millennia of burning alive.
 * Referring to them as human dolls, Sika Madu remarked that they can barely survive what is to him a mere 100 years. This is longer than a human's average lifespan throughout history. The humans produced would have had a longer expected lifespan than their descendants well into modern times.
 * Whether being able to sense it, or having background knowledge in humans, Sika Madu feels he knows the duration of their life spans. It feeds into the notion that while these were the first humans seen on Earth, the species may not be native to the planet and originated elsewhere perhaps on other satellite kingdoms.
 * What Sika Madu is unsure of is the amount of darkness that humans can gather within a lifetime. Although he may know the lifespan of a human, having them gather darkness is a new undertaking.
 * All the while creating humans as Sika Madu is considering matters, the homunculus drops a child with no physical resemblance to anyone known. This child finds it weird having a feeling that there was something they needed to do.
 * If this child's feelings are connected with what the homunculus and Mikaela have arranged it may be related to one of them with sealed memories of their former identity. The memories were not fully erased to leave a thought there was something needed to be done.
 * In having memories of Mikaela, presently in the cabin Yu comments that he found Mika. It is a distinct case where it could be Mikaela himself in Yu's body speaking that he found Yu the homunculus who he calls Mika, in Mika's body. It is similar with Mika answering that yes he got found. Something fleeting, it may have been a fondness for Mika being expressed more so since later Yu and Mika would speak firmly as themselves, and not the ancient beings of Mikaela and Yu the homunculus speaking as if they have found themselves in present day bodies.
 * While discussing how they did not have memories of the past, Mika feels it was just as well as he would not have been able to bear how long it took and would have given in to despair. The length of time may have been a factor, but that Mika could see Yu again sustained him for the duration he was apart from him as a vampire.
 * In commenting how the vampires seem to resent their eternal lives, Yu and Mika don't seem to consider their lack of emotions in the matter.
 * Remembering Krul apparently within Sanguinem, Mika considers she looks like she has suffered a lot.
 * From seeing how others have died and forgotten their past existences, Yu seemingly has an existential crisis where he questions the purpose of living given that. It is short lived, as he quickly resolves to reaffirm his commitment to helping Mika, along with Akane, the kids, and Guren as well. Declining the idea that he and Mika are the Mikaela or other beings from the past, and maintaining they are themselves also helps.
 * Reflecting upon how the only answer he could find was for him and Yu to escape together, Mika considers the idea that Akane and the kids is also something to embrace further.
 * There appears to be a line of ants in the cabin that Yu glances to. This comes before Yu comments how Mika said he could not change anything no matter how hard he worked should the ants be in a metaphorical sense.
 * After Yu questions if he ran away quietly and died having lived a peaceful life, Mika answers he guesses so. This leads to Yu addressing how Mika is becoming a full demon, where Mika would want Yu to live peacefully and not be possessed.
 * At some point, Yu had noticed Mika was becoming more of a full demon.
 * Questioning what Mika will do when he becomes a full demon, Yu has possessing him or trying to leave as two options, and guesses the latter one. Mika comments how Yu noticed that too. Yu is displeased at the idea that Mika would try to leave even if it is to prevent him being possessed should he become a full demon.
 * There is a recollection of Ferid murdering a member of Yu and Mika's orphanage family from chapter 1: "The World of Blood Legacy". This seems something focused on by Mika when considering the matter of seeking their resurrection.
 * Although some beings seem able to return to some form of life though without memories, Yu decides his and Mika's life is only through what they have experienced and not from any past memories.
 * In wanting to save Guren and the others from what they are suffering, Yu is not specific in detailing who the "others" could be, though where Shikama Doji has had his experiences it may be sympathy expressed for the First.
 * Helping others spurs Yu on and breaks him out of a brief existential crisis, and he is inspired further with the commitment for him and Mika to prevail against stronger foes.
 * Entertaining no notions that he may be connected to an angel from the past, neither that he and Mika are demon related, Yu classes them both as humans who may be weak but they are still going to find some way to win.
 * From traversing the memories, Yu and Mika were searching for information to help them win and not escape. It would appear that learning that Mikaela had his own as of yet unknown plan involving the sinful keys that were scattered is a practical means of discovering this alternative method of resurrection.
 * In case Mika had thoughts of leaving before he could become a full demon and possess him, Yu is happy to say he is not getting away.
 * Feeling they now know the rules of a game, Yu's course of action is to make their own rules. Framing himself and Mika as not being players anymore, Yu affirms they are the game designers.
 * Determined to win, Yu and Mika decide their next course of action is to acquire the seven sinful keys. They are currently held by Guren and Ferid.
 * Eight years ago Ferid was unaware of what Mikaela was. Where he was felt to have the Mikaela trait, it would appear Ferid did not know Mikaela was a physical being until much later in this time. For his limited understanding of this, Ferid seems to have thought the First wanted to become it. Unknown to Ferid it would transpire that rather than Shikama Doji seeking to become this Mikaela, the matter would concern him desiring to resurrect who was his deceased son.
 * Rather than "human's" which would indicate just Guren, the vampire spoke of the "humans'" delivery which may mean he was classing Guren as a part of all humans, or there were multiple people physically involved in the delivery of Yu and Mika into Sanguinem.
 * From his comment, Ferid as a vampire seems able to access a human's memories at this time.
 * The two vampires who updated Ferid on the humans transported into Sanguinem are both attacked by Ferid. While some vampires like Crowley are able to re-attach their decapitated heads it is unclear if these vampires were able to do so.
 * It is shown that both Yu and Mika were brought to a room where Ferid and Guren were to look into their memories.
 * Eight years ago, Guren was present in Sanguinem and saw Yu then where he would find him again in four years after he escaped the city.
