Here's the Situation

One faithful night, decisions have been made. Lucifer, guardian of purgatory, has brought in upon himself that the angels and devils of Heaven and Hell will collide and begin acting like regular human mortals, starting with education. The two angels and two devils are forced to attend a preparatory high school named Skyward Collision Academy or S.C.A for short. Same rules apply for human mortals. As freshman students, they have no clue what to expect. When worlds collide, it ends up being a duel for who's more superior. Devils or Angels? They could get along and become friends with each other easily, but of course had their feuds. Ace Kahima at this point couldn't care less if she had to go to school. She loved to read, sing, and play piano with her best friend Iris Miriya. As long she could do that, she doesn't care about having to attend school. Once Iris gets into a relationship with a devil boy, Ace begins to feel lonely and falls into a depression she thought had disappeared, till a little devil showed her the light.
