Synopsis

When a second moon, the True Moon, suddenly appeared beside the real moon, it set off an extraordinary event. Three years after its arrival, as the True Moon glowed with a vivid blue light, Ryo encountered a monstrous creature. Trying to escape, Ryo was eventually cornered by the beast. Just as he resigned himself to his fate, a crimson-eyed girl named Izumi appeared, swiftly destroyed the monster, and vanished without a trace.
