Amon and Akira visit Cochlea to get information about the Owl from Amon's former foster father, Donato Porpora. However, while they are there, the facility comes under attack by a large number of Aogiri Tree ghouls, led by Kaneki and Ayato!
After living together at a CCG children's home years earlier, Kurona, Nashiro, and Suzuya are reunited in combat at Cochlea. Ayato faces a battle against Shinohara, who is equipped with armor created from the remnants of his father, Arata.
Suzuya's hellish boyhood is revisited, and it is revealed how he came to work for the CCG. As Touka studies for her entrance exams, Roma, a new waitress, fills in for her at Anteiku. Tempers erupt when Akira joins Amon and Seido for supper.
Tsukiyama shows up at Anteiku with news for Yoshimura about Kaneki's attempt to become more powerful via serial ghoul cannibalism. Concerned, Hinami accompanies Tsukiyama to a coffee shop, where she again runs into Takatsuki.
City in Waiting
Yoshitoki is granted permission to execute the operation to eradicate the Owl. The CCG officers involved in the mission take time beforehand to write any last words they might have, as the 20th Ward is cordoned off and its civilians evacuated.
The battle between the CCG and Anteiku continues, and Koma, Irimi, and Yoshimura each engage the special investigators. When a civilian gets caught in the middle, Hachikawa continues to press his attack unabated. Shinohara receives some advice.
Deluge of Flowers
Suzuya is left to face the newly-arrived one-eyed Owl on his own. Aogiri Tree joins the battle against the CCG, who find themselves overwhelmed by the sheer number of opponents. Meanwhile, Kaneki confronts Amon, who stands in his way to Anteiku.
