Eriol Hiiragizawa

Eriol Hiiragizawa is a transfer student from England who arrives in Tomoeda and is later confirmed as the reincarnation of Clow Reed, albeit one who holds only Clow Reed's memories and is not the sorcerer himself. He begins causing disturbances with two guardian-like creatures, Spinel Sun and Ruby Moon; the latter takes on a human persona (Nakuru) and goes to the same school as Sakura's brother Toya. While under the guise of a female student Ruby Moon develops a strong crush on Toya while seeing Yukito as a love rival. Eriol causes strange occurrences that force Sakura to use and thus transform certain cards. Once all the cards have been transformed, Eriol tells Sakura that he aided her in converting the cards so they would not lose their magic powers, while Spinel reveals to Sakura that Eriol stopped himself from ageing long ago so that he could go to class and befriend and help her.
