Plot
The demon king is dead. However, the host of "Shuras", demi-god-like people capable of felling him, remain and are now effectively free to do whatever they want, with some becoming conquerors while others wander, indifferent to the world around them. Thus, with the identity of the one who slew the demon king being a mystery, these champions now spark conflicts among themselves, all to determine who is the mightiest and attain the title of "True Hero".
