Bio and background history: Amatsu lived a good and happy life in the real world; he had friends, family and other people there for him whenever he needed them. He was polite and could be quite childish around these people, so everyone was shocked to learn about his death; Amatsu had been walking home from school one day and been run over by a car while he was crossing the street.
He was brought to soul society and lived in Rukongai for a few years, becoming quite apathetic, before he was accepted into the academy. Being a quick learner, Amatsu quickly finished and entered the 5th devision. After a while he gained his bankai and became the vice captain of the division. Satisfied with the position he had Amatsu didn't do much more than to follow orders.
Amatsu easily got tired of this though and left the society, but not before he attacked his captain and hurt him pretty badly.
