Shūsuke Amagai, a member of a group that hunts down hollows, is unanimously appointed by the Thirteen Court Guard Squads as the new captain of the third division. He appoints Makoto Kibune as his third seat officer. However, Amagai and Kibune are not well-received by the third division members. On the suggestion of tenth division lieutenant Rangiku Matsumoto, Izuru Kira, the third division lieutenant, holds a welcoming party for Amagai, but Amagai collapses after one drink due to his low tolerance for alcohol. Gillians invade the Dangai, the dimension between the Soul Society and the human world, and the third division is ordered to destroy them. Kira leaves with the third division members. While fighting the hollows, the Kōtotsu, the cleanser of the dimension, somehow gets called in leaving the third division in a race to escape before being "cleansed". During their escape Amagai appears, and with a last minute rescue, destroys the Kōtotsu with ease. Then once they have calmed from their near death experience, they find out that Amagai is actually still drunk.
