50 years ago there was a holy war, during the holy war, hell was destroyed and demons fled to earth to live on earth as a non-aging superhuman but the catch is they're power fades when they're away from their domain. today there is a demon who found out a way to regain his full powers as a demon by killing humans in an unknown style. Ember is an ex-demon who has more humanity than most humans, she is misunderstood to be sadistic and evil. then there's a fallen angel named Marziel who was kicked out of heaven for sinning to save a human.
