After Seiichi defeats a gorilla-like monster, a Kaiser Kong, she proposes to him. The gorilla named Saria starts her new life together with Seiichi. While she is kind, innocent, and forthright, he still plans his escape from her since she’s a gorilla. 

After wandering into a cavern he finds a skull putting off a strange aura - the dark lord Xeanos. Seiichi begins to battle Xeanos, a creature as strong as most final bosses! However, disaster befalls Seiichi and Saria leaps in before him!
