After Yaiba loses the Thunder Orb during an intense battle with Onimaru, he sets out on a journey to find other legendary Orbs that will grant him new powers. Yaiba and his friends cross the sea to Shikkoku, where Yaiba struggles to seize the Water Orb. Then it's off to Mount Aso in Kyushu, where the powerful sorcerer Shiro Amakusa is waiting for them. Meanwhile, Onimaru is furious that his own Fujinken was shattered in their battle and can't be repaired, so he hatches a plan to revive cursed swordsmen and steal Yaiba's Raijinken for himself!
