The Greatest Demon Lord Is Reborn as a Typical Nobody

Demon Lord Varvatos grows bored with being the most powerful being of his age and chooses reincarnation as a way to experience an ordinary life. He deliberately adjusts his magical strength to what he believes will be an average level before being reborn as Ard Meteor.

His plan immediately goes wrong: the modern world's standards have declined so far that Ard is once again overwhelmingly powerful. Instead of blending in, he attracts attention from admirers, royalty, and even a former subordinate who wants him dead. Ard nevertheless remains focused on the personal goal that motivated his reincarnation in the first place.
