While I sympathized with spiky-hair over what happened to him, that dried-up the moment he revealed that he went along with the second captivity game. Dude's fucking mental, and I have to wonder if the author is too for writing this convoluted bullshit. If this guy really wanted some redemption, he would have pretended to play along with organization after they let him live, and tried to take them out from within with his friend before they could hurt anyone else. But no, instead they decided to help irrevocably fuck-up the lives of others so that this asshat can feel like some cunt he killed forgives him. Wat?
Eyama at least deserves to walk away from all this with the people in the organization (save that one female retainer) dead in the most painful way possible, and having given the rest of Aya's gang a generous dose of their own medicine. Dude had to put up with a painful betrayal and relentless bullying for three years while no one cared; to the point he seemed to be contemplating suicide. The only way I would enjoy seeing this clusterfuck end is if he told everyone (including his shitty parents) to fuck off and if they don't like it and/or come after him, he wouldn't hesitate to end them. That would be the only way I'd be happy with Aya survivng. Having to live with the memories of what she did to Eyama (and others), the memories of Eyama putting her through hell as payback, and him telling her he'll never trust her again after betraying him so heartlessly might almost be as bad if not a worse fate than him killing her; and it would be completely deserved.
I know it's not going to happen, but a man can dream. This story would have been much better if it had been a character study about Eyama as he finally snaps, abducts, and tortures Aya. Watching him violently shed the skin of a docile bookworm and grapple with vengeance, redemption, and self-actualization would have been far more compelling.
