Let me try to sum it up in one cohesive sentence.
Bleach is about a character who suddenly finds himself wrapped up in another world of adventure.
Basically. He gets powers from gods of death. He uses those powers to defeat monsters. He winds up going on different adventures. (dont wanna spoiler it)
anyways, its awesome. He does stuff. Powers up. a lot.
He looks out for his friends. He powers up more.
He does some cool poses.
Then he powers up.
