2
Kisuke Urahara's backstory in Bleach involves growing up with Yoruichi and Tessai in Seireitei, becoming a prominent member of the 2nd Division and head of its detention unit before being recommended as Captain of the 12th Division, where he founded the Shinigami Research and Development Institute (SRDI). Falsely framed for creating Hollows in the Rukongai, he was exiled to the Human World with Yoruichi and Tessai, where he opened the Urahara Shop and later mentored Ichigo Kurosaki, helping save Soul Society from Aizen. Urahara grew up at the Shihōin Mansion with his friends Yoruichi Shihōin and Tessai Tsukabishi. He joined the Gotei 13 and served in the 2nd Division, eventually becoming the head of its detention unit, responsible for imprisoning dangerous individuals. Around 110 years before the main story, Yoruichi recommended him to replace the promoted Captain Kirio Hikifune, and Urahara passed the rigorous test to become Captain of the 12th Division. As Captain, Urahara established the Shinigami Research and Development Institute (SRDI) and appointed Mayuri Kurotsuchi as his Vice President. He began developing Gigai to stabilize souls and conducted research that would later be used against him. Sōsuke Aizen framed Urahara for creating Hollows and causing harm, leading to his conviction, stripping of powers, and exile to the Human World, accompanied by Yoruichi and Tessai. In the Human World, he opened a convenience store, the Urahara Shop, selling Shinigami items. He became a mentor to Ichigo Kurosaki, training him and providing crucial support in the fight against Aizen and other threats, often operating from the sidelines but orchestrating events.
