I don't think anyone can really be on Kureto's side. More like, they serve him, and he kills them off whenever he pleases. He doesn't really work with anyone but uses them instead.

I imagine Yu would be restrained like Mirai and lose his sense of self and become a seraph under Kureto's direct control.
