One of my favourite AUs to think about is the one where Jyn really is ~30.
Honestly i wish kaneki would have to encounter a situation one day that will force him to break his "taboo" on killing humans, because this is really ridiculous. Idk, some sort of moral conflict is needed. Like, is a life of a HUMAN RAPIST is still worthy more to him than feeding 20 ghoul orphans? Like...why can't dude just understand that his so-called ideals are unneeded load of shit that is built upon hypocrisy. Hell, at this rate, tooru can kill all goat on his eyes, and he will do nothing.
