Introduction (Edited)

Y/n L/n was a lucky boy. He managed to win a special contest that led him to live with Off The Hook for the next year. Of course though being a third-year high school student also meant he still had to go to school still, but he manages to find himself in a class filled with girls who all manage to fall for him, but when something called the dark hour, the time between midnight and the next day, rolls around will he be able to protect his friends and keep up on his school work from the evil that threatens to wipe out all life? Well a certain long nosed old man seems to think so.
