Eriol Hiiragizawa

Eriol Hiiragizawa is the principal antagonist in the second half of the series, commonly called the Master of the Clow arc. The reincarnation of Clow Reed, Eriol has both Clow's memories and all of his magic power. He has a magical staff similar to Clow Reed's, can control Clow's creations Yue and Cerberus, and has created his own similar pair of guardians: Ruby Moon and Spinel Sun. He moves from England to transfer to Tomoeda Elementary school after Sakura Kinomoto passed the Last Judgement and became the official master of the cards. He is depicted as a quiet, mature boy while at school, though he also shows a mischievous side when he regularly joins classmate Takashi Yamazaki in weaving complex lies about the history of objects, places, and events. While seeming a normal student to Sakura, Syaoran Li is suspicious of him.

Eriol's true age is unknown, as he used his magic to halt his aging process to remain the same physical age as Sakura. He is romantically involved with Kaho Mizuki, whom he originally sent from England to aid Sakura in the Final Judgment and who offers Sakura support through letters during the second arc. At the end of the manga series, she returns with him to England, and in the second anime movie, they are shown together when Sakura calls for advice. In the anime series, Eriol is the sole reincarnation of Clow Reed, with all of the elements from the manga regarding Fujitaka's relation to Clow and inheriting of half of his powers removed.
