Shit man I totally forgot Touka doesnt know about the whole bone breaking lol. Does Hinami know? I don't remember if she knows or not but if she doesn't, I wonder how she'd react.
She doesn’t as far as I can tell. I wonder how Hinami would react as well tbh. Hinami’s fine with Kaneki’s violence because he’s still kind and protective of her. But Ayato is a really close friend to her, so I wonder how she’s react. Same with Touka. I don’t expect Touka to simply be silent about the incident if she knew, especially since Touka is very protective of Ayato.
Personally, I don’t think they’ll ever find out, at least not from either Kaneki or Ayato.
