Rui is the head Sorcerer of the Wonderland Kingdom. He works alone but his best friend always checks up on him and helps him in experiments. His best friend was Tsukasa, the head knight. They went on missions together sometimes but most of the time Rui ends up waiting for Tsukasa to come back from a a mission so he could heal his wounds and force him to rest. Currently, Rui was in his chamber working on random potions he found recipes to.
