Yukito has a second identity that he doesn't really know about named Yue. Yue is the second guardian of the Clow Cards. He is also the judge of who controls the Clow Cards. Yuki has no memory of what happens when he is Yue, but Yue can recall all that Yukito sees and does. Yue is very powerful, and he gets his power from the person who controls the cards. Yue was head over heels for Clow Reed, and he was very slow to begin to accept Sakura as the new master. He didn't want a new master; he just wanted Clow Reed back. Yue also has some issues when it comes to Touya and Yukito's relationship. Yue can see, feel, and remember all that Yuki does. Yue doesn't want to be involved with anyone other than Clow, and when Yuki is with Touya it causes Yue to feel unhappy. Both Sakura and Clow Reed have shown a slight favortism towards Yue over Kerberos. Yue would do anything to protect the cards and their master.
