Eriol Hiiragizawa (柊沢 エリオル)

Eriol came to Japan in order to aid Sakura and force her to use her own magical powers to convert the Clow Cards into Sakura cards. This is necessary as the cards take their magical energy from their master, but until Sakura converted them, they could not use her magic and were slowly dying. The guardian Yue also was suffering the same fate, forcing Sakura's brother to "feed" him all of his magical power to prevent Yue, and his false form Yukito, from dying.


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. The final explanation at Eriol's house is also shifted slightly so it takes place the day after the final battle, rather than immediately after, and it is done because Sakura seeks him out rather than his giving an invitation.
