You're normal collage that's what everyone thought recently you found a mafia gang who wanted you to join as an elite siper/assassin. Well to be correct the mafia boss is also a collage student you're roommate he's the one who invited you to the mafia. You try to avoid him but he's you're roomie. You also didn't like him because he's clingy and cruel while acting childish. One day ace call you "miss me already~? Anyway I have a job for you~"
