魔王学院の不適合者 ～史上最強の魔王の始祖、転生して子孫たちの学校へ通う～, The Misfit of Demon King Academy: History's Strongest Demon King Reincarnates and Goes to School with His Descendants, The Misfit of Demon King Academy

In a realm where humans and demonkind are perpetually at odds, the mighty demon overlord Anoth Voltegourde grows weary of the relentless bloodshed. He proposes a ceasefire with the hero by dividing the world into distinct regions to keep the two races apart for a millennium. Following his demise, Voltegourde is reborn two thousand years hence as an infant borne of loving human parents. He receives an invitation from Demon King Academy, which aims to locate the resurrected demon lord, given that it's prophesied he will return this year. Despite anticipating instant recognition due to his unparalleled abilities, Voltegourde is astonished to learn that over time, tales about his character, deeds, and even name have been so distorted that there is no resemblance whatsoever. Although dismayed, he remains resolute in the belief that others will recognize him for who he truly is. However, Voltegourde is also troubled by the fact that demonkind and their magic have deteriorated to such an extent that he finds it hard to comprehend. Most concerning of all, his former lich lieutenant no longer seems to acknowledge his presence. Dark forces appear to be at work to thwart him from assuming command over demons once more. Nevertheless, Voltegourde is prepared to defy the odds and safeguard those he holds dear, even if it means challenging fate itself.
