Kaigo (改悟, Japanese for Repentance) is the Shinigami stationed to protect Itoyuu City from the Hollow. He is a member of the 6th Division, being its 3rd Seat. He is the one who transferred Shinigami power into Clyde, allowing him to gain an Evolved Fullbring. After the Hollow Invasion he was held for questioning, but when it was decided to allow Clyde to act as an Agent of the Soul Society he was freed and allowed time to rest and regain his powers.
