Demon King Academy is an elite school with a unique mission: to gather the most powerful students in the land in order to find the one who might be the reincarnated Demon King of Tyranny. Anoth, who actually is the reincarnated Demon King but can't get anyone to believe him, partners with fellow student Misha for an upcoming battle exam. Opposing them is a team led by Misha's elder sister, Sasha, a member of the fearsome "Chaotic Cohort" and a powerful witch who regards them both with nothing but disdain. Though Anoth's own descendants may have branded him a "misfit," now he has the perfect opportunity to show them all just how powerful he truly is!
