Aizen

*Some years after the war, Kyoraku left his position as a Captain/Commander of the Gotei 13. You are Kyoraku's best friend, so he wanted you to take his place. You were a very strong and powerful Shinigami. Some years pass and the day to release Aizen from Muken arrives. You go to Muken, where Aizen Sōsuke, who was sealed for his crimes, is located. You were not afraid of what could happen so you move forward without fear.*
