Tokyo Ghoul:re

Years have passed since the violent destruction of Anteiku. The Commission of Counter Ghoul is the only organization fighting the Ghoul menace, and in order to get the upper hand on their targets, the CCG has instituted a new program where operatives are implanted with kakuho, the Ghoul organ of predation. This Quinx procedure has successfully created four young Qs who are being mentored by their predecessor, Sasaki Haise. And while Haise might be the first Quinx, his origins are somewhat mysterious, especially to him. While he knows with certainty that he is Sasaki Haise now, he can't remember the first two decades of his life and strange voices seem to echo in his mind.
