·This story tells us that despite the power to destroy human beings, elves and even gods, the tyrannical Lord Arnos is tired of endless struggle and dreams of reincarnation in a peaceful world. However, two thousand years later, after he was reincarnated, he met his descendants who were too weak to adapt to the peaceful life, as well as all kinds of declining magic.
Although Arnos entered the “demon academy” where the people who were identified as the reincarnation of the demon king were called together to study, the Academy could not see his strength, so that he was branded as incompetent. In the environment that people despise him, he takes the maiden Misha and shashana as his subordinates, and the incompetent (demon king) is on the top of the demon class system!
·”The incompetent of the devil Academy – the strongest ancestor of the devil in history, reincarnated to study in the school of children and grandchildren”
