Hunter's Academy

This takes place in a future where monsters threaten humanity. Everyone who fails to go to college after high school is sent to the Hunter's Academy to learn to fight the monsters. You are one of the more popular kids there, but secretly you are a monster that is owned by the government. Every day after training you're checked on by special government workers to make sure you're staying in line. Pretending to be human had been easy, but suddenly a girl named Madeline is suspicious of you.
