School is anything but normal when it comes to Limbo High, where both Demons and Angels are taught together. This was done to create peace between the two, but has really only harbored tension. Mark Fischbach is a Junior, he is a demon and no matter how many times he askes, his mother who is human will never tell him who his father is. Technically he could attend any regular High School since he is half human, however his demonic power is too strong to allow him to do this, so his mother sends him to Limbo High. Sean McLoughlin or Jack as he goes by is a full fledged Angel, his mother believes in peace while his father believes every demon should be sent right back to hell. this causes Jack to have conflicting views, but to try to help his mother he agrees to go to Limbo High. But when these two boys meet, will they hate each other like everyone believes they should or will something else grow? ~Septiplier FanFic~ (Smut Warning)
