Gensomaden Saiyuki: A Sin of Hope(幻想魔伝 最遊記 ―希望の罪過―)

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.
