Tokyo Ghoul - Season 1 (2014)

Kaneki befriends Tsukiyama and the two start hanging out. However, little does Kaneki know that Tsukiyama is preparing a mortal trap for him.

Intending to consume Kaneki himself, Tsukiyama prepares another trap for him, using Nishio's human girlfriend as a hostage.

He subsequently starts to assess himself, contemplating the fact that life is truly about compromise; for all along, he was weak, and lived by the belief of 'letting himself get hurt rather than others', which is the reason as to why his mother suffered so much. Rize confronts Kaneki, warning him that if he didn't sacrifice one thing for the other, his dearest ones will perish, and it's going to be all his fault-the disadvantage would arise as a ...
