Well, all we've got is that he killed East, and that she's probably confused herself with the Koko from that time (remember how Futa was having a hard time keeping track of who he is in the present?).
That's so far as much as I can tell: He did something that got a lot of people killed and the girl is having trouble separating herself from that. But, at the same time, whatever he did isn't enough for East to care that much (and/or he does a really good job of separating the different lives as actual different people, which is also possible).
I mean, the other option is she just really hates him more than the other lives but that makes no sense compared to just using the whole "can't separate herself from the other identity" that was introduced.
Definitely. I feel like it's all based on the fact that it's a circle, with no real beginning or end.
torus?! wait wrong manga
Feeling that it's looping, which makes me wonder if there's something outside the loop observing things? Hm.
