My Eyes.

There are 3 worlds.
Like heaven but not heaven-Solaria.
Like hell but not hell-Downarrow.
Earth stays the Earth.
Main character is Crypto, a demon, who gets kicked out from Downarrow because of mafia, where his brother is involved.
There he meets Emma, who would help to ease his pain of his past. When everything seemed to be lovely and going well, Downarrow's world mafia sends group of Demons to capture Emma because that's Crypto's only weakness.
Umm.. What would happen?
