The Gotei 13 (護廷十三隊, Goteijūsantai; 13 Division Imperial Guards, 13 Court Guard Squads in the English dub, 13 Court Guard Companies in the English manga) is the primary military branch of Soul Society and the main military organization most Shinigami join after leaving the academy. It is the most important faction of the Bleach franchise.
While the history of the Gotei 13 remains largely unknown, the organization was founded by Genryūsai Shigekuni Yamamoto, who has stood at the head of the group since its inception.
The first generation of the Gotei 13 consisted of Yamamoto, Yachiru Unohana and 11 other captains. Shunsui Kyōraku considers this generation to be the strongest version of the Gotei 13.
The Gotei 13 serves as a military force with its primary responsibilities consisting of the defense of the Seireitei. It is also responsible for the deployment of Division members into enemy territory for combat operations, the deployment of Task Forces as defensive measures in the Human World, and the guiding of souls to Soul Society.
