I'm very curious how the author asspulls his way out of Momo getting raped because realistically there's no way Jimi or anybody can save her. As for Jimi's backstory from 10 years ago, he more than likely got attacked, restrained, and forced to watch everything happen like a typical rape NTR hentai. Honestly, the author should just give Tsubaki a mustache to twirl at this point.
