[Machine Translation] The kingdom of Amelia, with its monopoly of sorcerers and supernatural powers, is expanding its territory. Bud, the lord of the small country of Campus Fellow, is threatened by this expansion, and decides to take an unprecedented and bizarre measure. He gathers together a group of vicious witches scattered across the continent to fight them. At the same time, news arrives that the "Mirror Witch" has been captured in the neighboring country of Rave. Bud leaves for Rave with his followers to take custody of the witch. Rollo is among them. He is known as "Black Dog," a boy raised to be an assassin. The curtain opens on a magnificent and vicious dark fantasy that no one has ever seen before.
