After 2000, the tyrannical Devil King has awakened-but his suitability in the college where the alternate Devil King is cultivated is-"unfit"?! Despite the power to destroy humans, elves, and even gods, the tyrannical devil Arnold Voldigoth was tired of never-ending struggle and dreamed of a peaceful world for reincarnation. However, after 2000, what he ushered in after reincarnation was his descendants who had become too weak to regulate a peaceful life, as well as all kinds of magic that had declined to the extreme. Although Arnos entered the "Devil King College", which is regarded as the reincarnation of the devil, the college could not see his strength, so he was branded as an unqualified person. Not only that, the legendary devil also became a completely different person from himself. In an environment where everyone despises him, he takes Mischana, the only girl who is kind to him, as his subordinate, as an unqualified person (devil king), to reach the pinnacle in the hierarchy of the devil clan!
