Ard Meteor was once Varvatos, the most powerful demon lord in history, until boredom with his own strength drove him to reincarnate as an ordinary villager three thousand years later. The modern world turns out to be far weaker than he expected, leaving him just as overwhelming as before despite his best efforts to blend in. At a magic academy he meets the elf Ireena Litz de Olhyde and the succubus Ginny Fin de Salvan, both drawn into political intrigue and old rivalries that follow him from his previous life. This manga adapts the original light novel.
