Summary: A violent demon king who has revived after two thousand years. "Anos Voldigord" is a violent demon who has reincarnated in peace world. However, after two thousand years, he was reincarnated and waited for his descendants, who had become accustomed to peace and became too weak, and a number of magic that had declined. Anos enrolled in the "Demon King Gakuin" that collects and educates those who are considered to be the reincarnations of the devil, is unable to see his strength and stigmatizes the non-conforming ones. Furthermore, the legendary demon king was supposed to be a completely different person from himself. In addition to being misunderstood by anyone, Misha, who will be the only one who will be intimate, will run under him, and a non-conforming person (demon king) will run up the demonic hierarchy!! After 2000 years have passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “inept”!? Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future. However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.
