After destroying an empire in China, it began to move on to a new country, but during its journey, it was attacked by the Beast Spear and found its powers all but useless against the holy weapon. It managed to escape but found itself faced with thousands of Yokai, along with a powerful priestess, Yuki, a reincarnation of Jie Mei, the girl who gave her life to create the Beast Spear. Knowing it was at a disadvantage, Hakumen pretended to retreat in their wake but really it led them to a situation where Yuki was forced to stop the yokai from attacking Hakumen, who had fixed itself into the base of Japan below the sea: If Hakumen was moved from this base, it would collapse and Japan would sink into the sea, destroying every life on it.
