Kingdom Conqueror

A Hero working for the side of the Demons and against Humanity

The Holy Grimoire gives its caster the ability to summon the Hero from the prophesies that is destined to save the world. But it was stolen by the Demon King's daughter Selare, who then used it to summon the Hero Drakar and she became his master.

Drakar was supposed to fight for humanity against demons. But was forced to fight the other way around because of the seal on his chest that brings intense amount of pain when he does not follow his master's orders.

Forced to side with the Demons, Drakar will conquer all of the Kingdoms.
