Saiyuki: Check Mate (Saiyuki Fan-fiction)

A group of 5: Hakkai, a level headed man that's like, I suppose, the mother of the group. He always keeps them together and at peace. Gojyo, a tall red head that has a strong feel for ladies and always argues with Goku, a monkey-ish boy that only cares about eating and... Well... More eating. Seichi, a strong-willed woman that holds the grudge of destroying all the evil Demons for the kidnapping of her sister; and Sanzo, the leader of them all... A cranky monk with a stubborn attitude that has a mission to travel west in order to stop the revival of Gyu-mah-o, a strong and powerful beast that wants to destroy all humans and let the Demons roam freely.
