The Strongest Demon Lord in History Reincarnates as a Village A-Ranker ~A (規格外) Villager's Ordinary Yet Extraordinary Heroic Tale~

Valvatos, the strongest demon lord in history whose name is etched in myth, seeks a peaceful life after a fulfilling reign as king. Using reincarnation magic, he is reborn as a villager in a world millennia later. Living as Aard Meteor, he enjoys his simple life until an unexpected truth is revealed at the academy he attends at his parents' urging. He discovers that the magic he uses is mostly Lost Magic, impossible spells in this era. His ordinary life as a villager is only 'ordinary' by the standards of the ancient world. In the modern world, where magic has weakened over thousands of years, Aard's abilities are exceptionally extraordinary. He finds himself thrust into the spotlight, with royalty vying to make him the next king and former subordinates plotting against him. Aard, however, just wants a normal life and will stop at nothing to achieve it.
