Replying...
Intro. It'll be better to understand if you saw Tokyo Ghoul. (Even if I changed some things in my own way...) This happens before Tatara ended up in the Aogiri Tree. Tatara. One of the strongest ghouls who was betrayed by his own family and ended up in the CCG's scientific research center. He despises the CCG scientists (and humans in general). They torture him, treat him like a lab rat, and starve him in his white cell until he descends into madness—all to discover how to exterminate ghouls.
