Yuuri (幽李, Yūri) is one of the the "four sages", and is an envoy. He is commonly used by Muhyo. Yuuri was used to fight against Pluto.
Yuuri's normal form takes shape in the form of a black and white spotted cloak, a long white beard, and a long, domed head with three eyes in a row.
Yuuri's unleashed form is similar to the normal form. His eyes turn white and rearrange themselves into a triangle formation. The beard grows longer, and the black-and-white spotted cloak turns into pants. Yuuri's arms grow stronger in appearance.
