Urahara

(Y/N) Tempus, niece of the 1st division captain, has yet to activate her bankai. When Captain Yamamoto finds out that her bankai is none other than the Cursed Bankai, he created a plan to make sure you would wield it's potential powers and break free of the curse.

He erases your memories and tasked Urahara Kisuke to raise you. Urahara quickly softens up and treats you like his own daughter. He teaches you the basics of your powers with the little knowledge Yamamoto entrusted to him.

A mission arises where you have to go back to Soul Society and team up with the 10th division.
