User blog comment:AquilaeAltair/OnS Theories. Third Theory - Mitsuba Sangu's demon and her role in the story/@comment-36009152-20190323010119

It is a sound observation on Mitsuba’s role in Seraph of the End, and it did need to be pointed out that yes she does have a larger role than Mika himself! What is good to clarify is though when measured some roles are larger than others, they are all prominent in their own way. There is never a want for certain characters because we know they’ wil be seen and it will be wicked? I hope people get what I mean, like with Mika he should appear on every page, but doesn’t yet that we know he and Yu will come across one another can carry a whole story… which is remarkable really.

Just on Mika whilst he was mentioned, do just want to share that with him kept in reserve and a best saved for later early in the series it was a rare case where that worked very well since withholding favourite characters is generally not a good idea when making a story. Compared to Yu, and of course Mitsuba here, Mika is not seen as much simply as the plot and world is set up for Yu to get to grips with. Then it turns out Mika is here to save Yu from the humans, and when regained – point is I love it, never left wanting for Mika, or Mitsuba who has her backstory shared in flashbacks at which point she is free to advance through the plot.

A curse being responsible for physical effects in people and their descendants, one blurred into a legend so people can maybe wilfully forget the honestly perverse hold demons can have over people! The thing is such a happening would be the most unsettling predicament to befall a person before vampires came along. Also on curses and demons, we have seen how Shikama Doji was content to bide his time for just a few generations so stands to reason this Sangu house ‘legend’ would emerge, well anytime!

Now this Mitsuba’s cursed gear theory was well hidden within plain sight. Think it’s because of other cursed gear like Akahebi, Iwasaki’s cursed gear chain; we are led to believe that Mitsuba’s axe is simply another impressive looking, and acting weapon. The thing is it maybe deliberately prevents us outright from thinking hold on why hasn’t a main characters cursed gear demon been elaborated on. Especially compared to the others that are gone into depth, more so especially when it’s an amazing gargantuan axe that can conjure multiple demons.

Then you provide the reminder that Mitsuba has an honoured family of her own, and we are shown in universe of the horrifying power dwelling behind the Hiragi family, specifically in Shinoa Hiragi’s somehow inconspicuous scythe.

I like where this is going XD Mitsuba’s demon must be some crazy thing, cannot put it any ohter way, responsible for a curse yet to reveal it’s full effects. Still, more keen to point out it may be a different type of demon altogether if it is being kept this long to detail. Though cursed gear are varied, Mitsuba’s axe is a design of it’s own.

As you say it’s this room full of the things they run the lines of generally speaking medieval like weapons, katanas, bows, swords in the same vein. With Mitsuba it’s the actual shape of her gear, it’s like some modern custom designed weapon? It looks incredible to be sure, only not something remotely similar to other cursed gear.

At this point, this is the only thing that arouses suspicion that her demon is not a ancient entity responsible for a curse, rather a recent and new creation to match her modern looking axe, aka a new type of created demon. Perhaps Kureto, or more likely Tenri were successful in experiments to turn vampires into demons their way before, possibly the same methods were responsible for Shinya's sniper gun.

Whether ancient or new… or ancient adapted into new, that her demon in its current state can have various incarnations, what if her fully powered demon is some mass-producing creature… maybe one that is capable of affecting multiple people. If blond hair is not a family trait rather the symptom of a curse (interesting effect, granted) then it’s not just Mitsuba but another Sangu family member in Aoi that can possibly be/become a case of multiple people affected directly by one demon. That would be startling indeed and if Aoi wanted to play a greater role in the story, such a power is a realistic check against another master manipulator in Shikama Doji.

Just on these family ties, Aoi and Mitsuba really highlight a war like relationship. That Aoi is dedicated to both her boss Kureto and protocol, in favour of her own sister is quite chilling but sadly accurate to real life. Seraph of the End goes to such lengths to show how good Aoi was with Mitsuba, guess family traditions make for a good career path even though they are directly responsible for Aoi rejecting her sister for the ‘dignity’ of the Sangu house. Darker than a demons curse, oh yes.

A glimpse of deception, or any expression of emotion is very important for the ever-keeps her feelings reserved Aoi. Her background and status in the military are responsible but it’s interesting whether this is a façade and what causes her to break protocol from essentially being a tool of Kureto – that she is fine with, that’s okay.

First aw, I do sympathise with Mitsuba, like any sister she would have lingering feelings, Aoi is her family. Mitsuba lost her squad and to see her actual sister right there but so distant cannot be easy on her. To interject, I am suspicious on why it would be stated Mitsuba has the same response as Shinoa regarding an older sister, one in Shinoa’s case who was turned into a demon. Did the author want us to think Shinoa and Mitsuba feel the same way because their elder siblings are in the same state - overcome by a demon? I know above I put Aoi’s conduct down to her taking her rank seriously, but what if the reason why she is so stoic and aloof is because she is not an aide, but a demonic tool of Kureto, that Aoi herself is fully possessed by a demon.

To go on if this demon is the family curse one that can be in Mitsuba’s weapon and in another human at the same time (multiple apparitions being it’s distinguishing trait) then that would be troubling to put it mildly. Sure Aoi could be a puppet to this demon that is also on standby to possess Mitsuba at any time - the author has something in store for Mitsuba, and we know little to nothing about her demon to begin with. I then wonder what its relation with other beings really is. It could be the case this demon was Kureto’s guarantee against Seraphs, if the demon of the Sangu family were to be a check for Shikama Doji, well around the mid 70’s chapters seems to be the best time to deploy, what with Shikama himself running around like the scythe wielding lunatic he is.

Interesting parallels with Mahiru gaining assurances to save Shinoa, from her own father of all people. I think you are correct about Aoi and Mitsuba may have been close but sticking to ones roles and serving as a shield elsewhere came first. Alternatively Aoi is truly some emotionless puppet of this Sangu family demon. Perhaps the love Aoi feels is a love of power or even the inner demon as it is aware of what is behind the Hiragi family and it is attracted to that. All conjecture, honestly I want to say I hope both Aoi and Sangu are not haunted by some curse like the Hiragi family, but the dots are being connected and the image is not looking too good for them XD

Yes Mitsuba shares with Yu a large loss of people she cared about all at once, not too keen on authority especially for the formers case it was likely because it was Shinoa chosen as captain!

You are right there, Mitsuba’s demon is now suspected of being saved to bring out, well right about now with the current place in the story. Shikama is on the loose, and guess who the only person available to save Yu is? Even Mika, alongside Guren and others are pinned by the advance of Shikama, Shinoa for obvious reasons is in no state to save anyone, she requires the saving! Mitsuba has got this, though assistance from a fully awakened demon would always be useful. Then that forced appearance would provide our answer on it’s capabilities, how Aoi reacts to it, if Kureto knows of it’s potential.

With Kureto it is unlikely that he has Aoi as some possessed person as a guard with a fully powered Tenjiryu to rely on in all honestly, unless he is a massive risk taker and wants it kept even reserve until later. I mean Guren was willing to take some serious risks and stall for time in Shinjuku for the main army to arrive. Kureto may be willing to wager surviving against Shikama since vampire progenitors under Urd Geales, oh and Saito on the move.

Channelling powers into different areas is a forte of many people. Shikama’s talents, that Cursed gear weapons are filled with demons, stands to reason this ancestral curse could be fused into a weapon. A nice modern one at that like Mitsuba’s axe. Would wager Tenri would be aware of the Sangu demon curse, and through him Kureto, if he ever told him before Kureto carried his plans there. As for Shikama I’m not too sure, depends if the demon is one being used as a tool against Shikama, though he would be aware of it through the Hiragi family secrets. It’s another thing altogether if he even cares about it and perceives it as a threat.

As said above, the moment of needing her demon to reach it's full potential could be losing Yu who has been kidnapped right in front of Mitsuba. Then again, could be this theory in which case it may be her deep down treasured sister who Mitsuba needs to be worried about.

Sure they are close but it’s hard to state who Mitsuba considers her most important person. Of course your reasons for it being Shinoa make sense though simply knowing someone a long time may not be everything. Maybe it’s because I’m thinking of Aoi and I wonder how Mitsuba would react if there was a worst scenario to occur. Choosing her squad, or her sister who she realises she does miss very much so.

No matter what it is, am looking forward to Mitsuba’s planned role in the story, and her ever unknown demon. Will suggest it now but it’s not really going to be good news for them, since when are demons ever good news XD still would be interesting to see if this is an altered variation of demon, namely a multi possessing one and then what it's plans are for the descendants of the Sangu family in Aoi and Mistuba.
