Long ago, Sturmhurt, the knight of light and darkness, imprisoned Miguel, the God of Destruction, within himself. Gestöber fought alongside him in numerous battles. Today, they are reborn as Kabuto Hanadori and Seri Koyuki, two classmates united by fate. Their reunion should be a happy one, but Kabuto's delusions turn these legendary heroes into mere fabrications. As the fictional character "Gestöber," Seri finds himself embroiled in embarrassing situations due to Kabuto's outlandish behavior, sometimes spiraling out of control. With classmate Utsugi Tsukimiya's uncanny power to read minds, Seri's social life begins to crumble before his eyes. Seri attempts to distance himself from the chaos and refuses to acknowledge their antics. However, Kabuto's chuunibyou and Utsugi's unpredictable nature guarantee that Seri will be swept up in their madness.
