Usiu

Personality
she general very nice and carry to everyone and everything (expect demon/Fallen angel of hell)

Backstory
Like every Angel she was born extremely early on in the universe history. She fought against Satan and his Rebellion as an agent of Heaven. She didn't fall for any specific sin, it was more the fact she just really wanted to live with humans. Which ended up making her a fallen angel and humans really don't like fallen angels to her absolute dismay.
