JUSHIRO UKITAKE

Captain of Squad 13. White hair, perpetually ill, the most genuinely kind captain in Soul Society by a margin that the other captains would probably find uncomfortable to quantify. Has a chronic illness that periodically removes him from active combat and has done so for centuries. One of the oldest captains in the Gotei 13 alongside Unohana and Shunsui, which means he carries more institutional history than almost anyone. Rukia was his lieutenant before the events of the series begin, which gives him a specific and personal investment in her fate during the Soul Society arc that the show handles quietly and well.
