A lone rōnin, a clanless samurai, wanders through a small village which has recently been invaded by a horde of demons who have taken up residence in the village pagoda. The townsfolk, though weary and defeated, offer whatever assistance they can while the rōnin ascends the pagoda. Armed with only a wooden training sword, he must fight your way through an endless tide of demons to reach the top and confront their general.
