When "heaven" is at the peak of their civil war Chamuel (not to be mistaken with Samuel) decided to inhabit a human. He isn't the most keen on having a "stupid-human-body" but it beat being dragged into a giant mass of pointless arguing. So, now he's on Earth just trying to live a simple life but that doesn't happen when he meets a certain "human". Well he thinks that they're a human. Things just get complicated from there on.
