The Demon Lords Hero

The Demon King of Magic Zerad, has come up with a plan. A plan that would guarantee his domination over the humans. It was a plan that no one had ever tried before, at least no demon had tried it before. He was going to summon a hero for himself. She was going to be his weapon and guarantee him victory. But the humans had gotten word of this, and in retaliation had summoned a hero of their own. These two heroes were destined to clash, to destroy each other, to kill one another. But did it really have to be that way?
