Heroes

Heroes (勇者, Yūsha) are people with special powers chosen by the gods, bound by fate to defeat or protect the Demon King to make a peace.

Overview
A maximum of ten heroes are allowed to exist in the world, each of whom have their own unique abilities. As shown with Keyaru, a hero can be identified with the signature insignia they have on the back of their right hand. An exclusive trait to heroes is that they do not have a level cap, and can increase the level cap of other people most efficiently through sexual intercourse. Those in a hero's party receive double the experience points.

If a hero dies, it takes an average of two years for a replacement to be chosen. During this period, if there exists someone compatible with a mark a deceased hero possessed, it is possible for them to be chosen once they reach a singularity point and take the trial of the hero.

A hero can use what is called a Holy Armament, an object which transforms into a desired power or weapon after forming a contract with the user. The signature weapons of Blade, Bullet and Flare are their respective Holy Armaments given form.

As revealed by Brett, there are some secrets treated as taboo regarding the heroes known by few, for example the true purpose of the heroes' existence, completely different to the commonly learned objective of defeating the Demon King, it's protecting it, trying to make humans and demons live together, For example, Keyaru, where he protected Eve Reese, the Demon King Candidate who wanted to kill the incumbent demon lord Hakuou until he became the true demon lord of the Black Wings Tribe (kuyoku).
