Fear, the only thing you will feel after seeing this scenery. Corpses all over the soil, gallons of crimson red liquid flowing from the bodies while raining, A scene of massacre where a single person's standing in the middle.

Aresia Academy located at a nation called "Ceris" . An academy that trains future hunters thus as a student you're allowed to bring your own weapon for self defense as well as for training except a gun. The reason is that it can kill a person with ease. Among the students there is a single person that isn't bringing a weapon since the entrance examination, the same person didn't fight at the entrance examination that is a battle royal and the ones who remains standing will be admitted, but he's still admitted to the school without fighting and just sitting aside at the day of entrance ceremony while watching the others fight. A rumor spread that he is a son of a high official at the "Hunters" organization granting him the right to be admitted, it gained him a title, "The Weaponless Connections Guy". He's not actually bothered by it and continued his school life until a certain situation occured.
