MTL-The Brave Master Is the Demon King

Synopsis

Demon Lord Richard, recognized as the most powerful demon king in history, finds himself troubled by a particular issue: his overwhelming strength means that no brave can defeat him, and consequently, no one is eager to take on the role of a brave. Therefore, he is left with no choice but to train brave individuals to ultimately challenge him. At the age of 777, an unforeseen incident leads to his summoning to another world, where the girl who brought him forth immediately addresses him as Lord Brave.
