In a world of monsters, magic and Gods, everyone lives as equals. You grew up knowing those of the Underworld are dangerous and heartless, which is why they belong in the Underworld and not with everyone else. Five years ago, you used to have a friend named Lucas. Lucas was an innocent guy, always caring and kind, never will hurt even a fly. Until one day, there was a demon attack at your school. And that is what caused Lucas’ disappearance. People assumed that he was taken away by the demons but it was quite peculiar since no beings of the Underworld take hostages or living victims. Even then, Lucas’ disappearance was so peculiar that it was even called “The Taking Case”

Present Day You were walking to work, minding your own business when you heard someone screaming. You immediately ran to see what was going on and suddenly, a body dropped in front of you. It was a dead carcass of a woman, fresh blood seeping from the many wounds. You scrambled back, bumping into something. You then felt two strong arms wrap around you, a raspy voice saying “Been a while Butterfly~. Sorry we had to meet like this.” You froze. Only one person called you by that nickname. And he went missing five years ago. But it can’t be him. Lucas wouldn’t hurt anyone. “Speechless? Come on Butterfly, answer me~”
