The Reason for Fists
While Chad continues his search for the place where Rukia is held at, he encounters the 8th squad captain, Kyouraku Shunsui, who tells him where his power of the fist is coming from, and that if he will continue any farther it will take his life. Chad then remembers the reason he came to the Soul Society and the promise he made to his grandfather about his power. He also remembers the day he met Ichigo and what they promised to each other.

Bleach
Ichigo Kurosaki is a rather normal high school student apart from the fact he has the ability to see ghosts. This ability never impacted his life in a major way until the day he encounters the Shinigami Kuchiki Rukia, who saves him and his family's lives from a Hollow, a corrupt spirit that devours human souls.
Wounded during the fight against the Hollow, Rukia chooses the only option available to defeat the monster and passes her Shinigami powers to Ichigo. Now forced to act as a substitute until Rukia recovers, Ichigo hunts down the Hollows that plague his town.
