A world were some humans give birth to children with animal characteristics, but they abandon them because they are scared of them. These children are called monsters because humans are unsure why they exist or what they are capable of so they send them to a boarding school, from kindergarten up to college level.
A guy has a childhood monster friend whom he gets separated with cause of the law that the monsters has to be sent to the shcool. When he gets a bit older he transfers to that school, where he wants to make a change in the law. Very cute but the manga/upload was very blurry so couldn't read it for the most time.. :/
