User blog comment:AquilaeAltair/OnS Theories (S3). Sixth Theory - Mitsuba Sangu, a girl that saw the heavenly sky before the catastrophe/@comment-36009152-20190823163104

This 17th volume! A good verdict on Mitsuba as well, despite her background as a member of her family she certainly threw herself right into the thick of the action of her own accord. Yet just as well she is an even better team player after transferring to her new squad.

Shinoa’s account of Mitsuba has some truth to it, being promoted after the battle of Shinjuku purely based on her relation to the Sangu family XD and mostly to Aoi who serves Kureto directly which is certainly a factor in her extreme loyalty to the Japanese Imperial Demon Army.

Like the points about how there would be more than Aoi’s upbringing that would shape her views towards Mitsuba. Also how we need to be on the lookout for character reactions for hints on past interactions.

Seraph of the End really does throw them together, having Ferid in the presence of the squad to have a chance against larger threats. Guren and Kureto with their background, and extended to Mitsuba and Aoi where the latter was fully aware and compliant in what was to occur. Would be interesting if Aoi was regarding Mitsuba amongst a squad, her friends, whereas she had her life planned and set.

Hopefully we will get to see how they were when they were younger and the frostiness is thawed in later chapters as well. Unfortunately, particularly with the ever closer connection with Kureto cannot yet see how Aoi could reconcile with Mitsuba. If he is still giving orders, Aoi will still carry them out regardless of lingering feelings (if they were even there) for her family.

That’s a good point, orphans Yu and Mika, to Shinoa being caught up in family affairs. That Mitsuba may have had it easiest but ended up with the temperament she has is funny XD

The thing is Mitsuba's time to shine in the darkness of the story (how poetic!) is a window that is fast closing. Through no fault of her own, Mistuba, well, unlikely any human has to means to save Shinoa from her on-going possession. If Mitsuba wanted to save Yu when he was kidnapped right in front of her, Mika is beating her to it. As for assuming command of the squad, Kimizuki along with Mirai, Yoichi and presumably Narumi are hightailing it away from Shikama Doji. Indeed Mitsuba on her own hasn’t been shown at all, so good news the story may have something planned for her, and better it will be a surprise because the obvious actions are being carried out by others.

Appropriate for this theory, that’s why it points to Mitsuba seeking out Aoi, what else can she do? There is an all out assault on Shibuya, the first and Saito are running amok, there are vampire progenitors on their way. Mitsuba’s fond memories of her past with her sister may be what it takes to heal the rift between them, something needs to be done for both of them to have chance with separate dangers coming together.
