In the distant past, Miguel, the God of Destruction, was sealed inside the knight who ruled over light and darkness, Sturmhurt. Alongside the knight was Gestöber, who accompanied him through countless battles. In the present day, destiny causes them to reincarnate as Kabuto Hanadori and Seri Koyuki, two classmates.

Their reunion should be a joyous moment, if not for the fact that these fantasied heroes are just products of Kabutos delusions. As the fictional Gestöber, Seri finds himself in various embarrassing situations due to Kabutos antics that sometimes grow out of his control. Moreover, his classmate Utsugi Tsukimiya joins the fray with his absurdly accurate mind-reading abilities, slowly destroying Seris social life.

Seri tries hard to stay away from them, refusing to acknowledge their shenanigans, however with Kabutos chuunibyou and Utsugis unpredictability, he is only bound to be swept by the craziness coming his way.
