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.
During Kaneki's visit with Yoshimura, he asks for information about the Owl, and is told the tragic tale of a young ghoul named Kuzen. Touka makes plans to move out of Anteiku. A snowy day brings with it brisk business at the coffee shop.
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.
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.
