idk this looks like a copout for the author to speed things up, and jump straight to the next level, because he realized this arc is taking too long. But I'm not complaining
Yeah the "delusional thinking" is not convincing enough, Eiji is definitely getting NTR'd by his own self.
How does he not realize B-1 is trying to get rid of him? He doesn't look like he's taking this seriously.
