Burn Bright! Cosmo of Love
Back in China, a blind Shiryu is suffering for not being able to do simple things like training or holding a cup of tea that ShunRei had prepared for him. When ShunRei takes him to the river, so she can swim in it, a strong current makes her start to drown, and Shiryu can do nothing. She is saved by a man who Shiryu knows very well: Oko, who trained with him in the childhood and had been expelled by Roshi because of his violent spirit. Now he's back to kill Shiryu and get the Dragon Cloth, but Shiryu's cosmo is so weak and opaque that Oko loses the will to fight and leaves. That destroyed Shiryu's pride, and now he's suffering even more, since he feels he's not worthy to fight along with Seiya anymore. Meanwhile, Seiya desperately looks for something that can heal Shiryu's eyes and eventually departs for Mu's Palace in Jamiel, believing that Mu might now a way to cure Shiryu.
