Long ago, fierce legendary gods shook the earth to its foundations with their power. Now, prehistoric rivals from primitive times in Japan fight to protect their secrets in the present day. The God of Darkness, Susanoah-oh, sleeps in the shadows of the underworld, awaiting his rebirth. However, his coming has not gone unnoticed. Agents of the Kikuchi Clan (descendants of Japan's first inhabitants) have seen the warning signs of the spreading darkness. These investigators, armed with ancient knowledge and artifacts, are willingly prepared to face the God of Darkness. Now they must fight the assembled spirits of hell to find the one young boy chosen by fate to grasp the chaotic might of the deadly Gods.
