An era when the battle of the talented "Bastard" who confronts the world threat "Bug" became the entertainment "Bastard" which is broadcast nationwide.

Kota, a student at Onagi Gakuen, a buster training school, did not perform well with "Bastard" because his awakened ability was specialized in defense, and he was given the unwelcome name of "Lowest Man (Bottom Number)".
