Toshiro Hitsuguya was born December 20th in Rukongai, Junrinan province of District One. He lived with his grandmother and Momo was his only friend. He could have lived there for centuries before joining the Gotei 13, but it's 더 많이 likely that he is actually somewhere between 90 and 150, which gives time for the rest of Bleach to unfold. In physical appearance he's about 13, maybe even 14, although it's kinda hard to tell since he's so short. X3
