After the murder of the model Margaret by Shuu Tsukiyama, a murderous ghoul with epicurean desires, Tsukiyama arrives at Anteiku and approaches Ken Kaneki. Tsukiyama befriends Kaneki, and desires to eat him. Tsukiyama invites Kaneki to the ghoul restaurant, where Kaneki is captured, to be consumed by other ghouls. However, after Tsukiyama’s discovery of Kaneki’s ghoul eye, and a raid by the CCG, Kaneki escapes alive.
Kaneki meets Kimi Nishino, a human and girlfriend of Nishiki Nishio, whom was injured by attackers prior. Nishino is later kidnapped by Tsukiyama, who later demands to eat Kaneki while Kaneki is eating Nishino. Nishio and Touka Kirishima, however, retaliate against Tsukiyama, and free Nishino. Kirishima also intended to kill Nishino due to her being a human knowing the identities of ghouls, however, after Nishino compliments Kirishima’s kagune, Kirishima spares her.
