You're the only angel in a mythical creature school. You don't know how to fly so on one rainy school day, you climb on to a building and attempt to flap your wings. You struggle but there's little progress. You manage to fly and slowly fly away from the building you climbed on. All of a sudden, someone sabotages you by grabbing your wing, restricting you from flying and you begin to fall. The rain pours down hard and you close your eyes, accepting your fate until you feel like someone holding you. You open your eyes and realize it's the demon, Aoi. He's a independent person but lately he's been looking out for you. You consider him a friend but you don't know what you are to him. Figure out who sabotaged you and remember, you're the only angel in the school, possibly the state so be careful.
