The Hero of the West is dead. The world doesn't know that yet and the Council Of The West would like to keep it that way. They pushed the responsibility to a young man named Moon--a friend of the Hero. And sent him an Academy student, Mina, as his apprentice--who wanted to be a hero. Demons were rampaging the world within their wall. And it had to be the duo to deal with them. And if only they were a little stronger like the former hero, there won't be so much dead.
