Aoi is the 'blue' fraction of the deity, hence his name. The blue deity is devoted to the balance and harmony of all living things, bringing tranquility and calm to the masses. However, Aoi was never very good at this, so he resorted to giving everybody crack instead. This really didn't work out so well. Eventually, he gave up entirely, which explains why the world is in the sorry state it's in.

He pretends to like Metallica so he doesn't look gay but is actually a devoted fan of The Cure. It was recently discovered that all of his Metallica CD cases actually contained burnt CDs of The Cure and Linkin Park, proving once and for all that he was a twelve year old girl, and a music pirate, the most evil combination of all things on the planet. If he only knew that Robert Smith is actually, despite popular belief, awesome, then maybe he could completely embrace his love of unplugged music. Then he might not feel so bad about being such a girl.

Aoi is often considered the prettiest of the group, probably because he spends so much of his time around acoustic guitars, which has been proven to make you absolutely gorgeous. Unfortunately, it's predicted that eventually this will all go to his head, and the others may murder him out of jealousy.
