A mysterious light falls from the Heavens. It's the Pearl Jade. It can grant any wish. Dr. Ni tells Gyokumen Koushu about it. Lirin overhears and tells Kougaiji. Then Kanzeon Bosatsu (The Merciful Goddess) requests "orders" Sanzo and company to go and find and seal it before it falls into the wrong hands.

First OVA starts with Sanzo and his master, also with Ukoku (known as a later Ni Jianyi). Second OVA shows first meeting of Goku and Sanzo. Third OVA considers the events after Hakkai's sins and his trial (that we know from first season of "Saiyuuki") and his decision to live in Gojyo's house.

An OVA adaptation of the climactic part of Saiyuuki Gaiden.

Based on chapters 11-13 of the original manga with additional content written by the manga author. The story will be told from Tenpou's point of view.
