Five hundred years ago, the evil Count Mandala of the vampire and his minions fought with the current headmaster of the school named Kasemon Oku. Their epic battle of good vs evil took place on what is now the school. No side had a winner, but the only thing the headmaster could do was seal away Count Mandala to stop his evil plan to take over the world. The headmaster knew that Mandala wouldn't be sealed for long, so he built the school, in an effort to strengthen the seal he had placed on Mandala.
After years and years of peace, Mandala's forces started to cause havoc again, searching and searching fo their masters resting place, wanting to break his seal and bring him back to his once powerful self. The headmaster heard rumors about their recent activities, and is now ordering that everyone be taught combat everyday for two hours. He did not give a reason why, for he didn't wan anyone to worry before time, but he knew he would soon have to tell them, for once the enemies arrive, there will be no telling what will happen.
