It was only a standard morning. Akira Shiroyanagi, a high schooler who cherishes diversions and Konpeito (Japanese desserts), has all of a sudden been hauled into a war zone by a baffling young lady who calls herself Mion.

Akira is resolved to win with his freshly discovered powers and devastate the association. Equipped with a power nobody expects and his "cerebrum" aptitudes, the new time of knowledge clash of starts!
