The Heartless are the thing hiding under your bed when you are a child. They are that thing that you thought you saw moving in the darkness. They are that thing you thought you heard in the cold of the night. Whenever you are alone, but you feel like you're being watched, the Heartless are the ones watching you. They are terrible creatures made of nothing but pure and utter evil. What would happen, however, if someday a Heartless were to gain a soul? What if that Heartless decided that he did not want to be like the others? His name is Heartbeat, and this is his story.
