Eriol is a transfer student from England and shows up in season 2(???). Eriol is a very mysterious character from my point of view and I don`t really know much about him. He has very strong magic that he used to create Spinel Sun and Ruby Moon. When Eriol shows up in the show he causes problems to occur (snowing snowmen, sheep in the sewers ect..) He does this so Sakura has to use her cards. In doing so this makes them stronger then they were before.

Eriol is a very strong magician and is half of the reincarnation Clow. He retains a great deal of Clow's power and beliveing that one person shouldn`t have that much power gave it to the other reincarnation of Clow, Fujitaka. Because of the power given to Fuji he was able to see the ghost of his dead wife. (awwwwwwwwwwwww)
