In the village of Kaboy, a mysterious plague spreads, while the villagers lose their lives one after another. The brave Teruhiko left six months before looking for a medicinal herb to cure the disease, but he hasn't come back yet. Chosen as the new hero, Yoshihiko sets out with a legendary sword.

The fellowship, who is told by the Buddha to head east to defeat the Great Satan, arrives at Kirana village. At night, monsters attack the villagers and fields, causing panic to spread through. When Yoshihiko hears about it, he assures the townspeople he's going to get rid of the monster...

As they want to defeat the Great Satan, the fellowship follows Buddha's instructions and heads east one more time. They are told they must assemble special equipment to defeat the enemy. First of all, they are told to get the"Celestial Feathered Robe", so the party go to the Celestial Cliff, where it should be located, on the upper side of the river.

The fellowship decides to head east after Buddha told them to get a "God's Helmet" that bounces off any blow. However, Danjo, who ends up fighting some monsters along the way, casts a confusing spell and accidentally injures Yoshihiko.
