Despite their appetite for destruction, even demon kings tire of all the blood and chaos sometimes! When Anoth reincarnates in the hopes of a more peaceful life, he ends up going to school with his descendants in his old castle 2,000 years later. But with magic on its last legs in this era, no one is able to assess Anoth’s true power!
