CLOW REED SPOILER!

The extraordinarily powerful magician who created the Clow Cards, Cerberus and Yue long before Sakura was born. Clow is already dead when the series begins, yet almost every magical rule Sakura encounters exists because he designed it, and his ability to foresee the future means even his absence feels suspiciously organized. In the television continuity, Eriol Hiiragizawa is Clow's reincarnation and carries his memories and magical legacy into Sakura's era. Clow's final problem is therefore not defeating an enemy but arranging for his creations to survive under a new master whose power works differently from his own.
