Reading the new chapter from MangaDex:
Not sure if we've ever been inside Seo's head before, but this basically confirms she's not faking it.
Komachi's response is very, very interesting. It could be a result of her being a massive masochist, or she could've had some secret relationship with Seo prior to memory loss (that hand gets awfully close to her face). In particular, in Chapter 30, Komachi says "she's alive, though..." where the "though" could have been referring to Seo's loss of personality, if she visited her before the others. On the other hand, it could also easily be "she's alive, though she should be dead." Another theory is that Komachi wants to maintain how the world should be before Satsuki changes fate, which would explain why she acts so coldly towards Akira, whose personality was completely changed by Satsuki. AFIAK, we also still don't know the true perpetrators behind Seo's first murder attempt, even if future attempts were made by the council.
The Prez pretty much confirms what we already know: he believes that death is a zero-sum game, and his goal isn't to win, but to convert Satsuki, which is something that will never come back to bite his ass 100%.
Poor Akira. I hope she doesn't go through a self-doubt arc where she considers herself unworthy to be by Satsuki's side (though it would also give a perfect opportunity for a confession).
