Kaneki starts receiving self-defense lessons from Yomo. He meets Itori, who runs her own bar, and is friends with Uta and Yomo. Kaneki is befriended by Tsukiyama, a ghoul who knew Rize, who also enjoys reading, and possesses other, more epicurean tastes.

After Kaneki and Hinami witness Ryoko's fate, the personnel at Anteiku are grieved, and Touka decides to take matters with the investigators into her own hands. Kaneki is fed up with not being able to do anything, and makes up his mind to become involved.

The 11th Ward offices of CCG are attacked by ghouls, wiping everyone out. Banjo and company stop in at Anteiku, looking for Rize to warn her to flee from Aogiri Tree, a new group of ghouls bent on taking over-- until Kaneki accidentally knocks him out!

Now with Kaneki at their ranks, the Aogiri Tree takes the offensive against the CCG, and Amon is introduced to Mado's daughter Akira, who is assigned to become his new partner.

The appearance of the "One-Eyed-Ghoul", considered the most dangerous of them all, leaves the CCG in a state of alert while Kaneki writhes in pain due to his new condition.
