Eighth Division

The Eighth Division (八番隊, hachibantai), also known as Squad 8 in the English Dub, is one of the Gotei 13, headed by Captain Shunsui Kyōraku.
The 8th Division follows the traditional organization of a Gotei 13  Division.
Like all the other barracks, the 8th Division Barracks house the offices and living quarters of the Shinigami of the 8th. During the Ryoka Invasion, Chad and Kyōraku fought on the barrack grounds. Chad damaged part of the barracks greatly during the fight.
