In Bleach as the Spirit King's Son

The world of Bleach is already full of stories, places and characters that we all know. Of course if you were to add a little something to it, nothing much would change, right ? Not if you change some important aspects of the main story, and, introduce a completely new character that know way too much about this world. This is the story of a human who will go from an infamous vigilante, to the son of the most powerful being in the entire universe......A fictional universe of course.
