It has been three months since the demon lord was defeated and a tournament is taking place in the demon world to choose his successor. The main contestant is Herc, a human hero who claims to hate his own kind. Some people don’t like the idea of a human becoming the next demon lord, especially Vermilion the Red. All he wants is to protect the tribe from demons and prove that Herc is his enemy, even if he has to create a competition to do so.!
