From SEGA: Raikoh, the famed undead warrior, managed to temporarily save the Japanese population from an onslaught of demons, but had not vanquished them all before returning to his grave. The demons have regrouped from hiding places within the sacred capital of Japan, and they are attempting to take control of man once more. In response, four brave warriors take their own lives in a ritual to resurrect Raikoh. Raikoh returns to life and the selfless warriors rise with him, set to take on the encroaching demon spawn as a team.
