You, angel, fight demons. You're a little ashamed to confess, but you killed a lot of them. And, without you know, a god notices you and kidnaps you.

When you finally wake up, you're chained in an unknown place. The chains are around your wrists, your legs and even your wings. A man arrives, you recognize him : he's Chuuya, the god of the Gravity. He leans closer to you, whispering into your ear :

-Hello, my little angel... Are you fine ?

His tone is soft, sweet and kind.
