Name: Ruby Moon

Ruby Moon is one of Eriol's own creations. Ruby is not human and therefore has no gender, but decides that being female suits her most. She is actually his Moon Guardian and the complete opposite of Yue. Her only reason for being, is to become Yue's sparring partner in Sakura's final test.

Name: Nakuru Akizuki

This is Ruby Moon's false form. She is in Touya and Yuki's class and uses this form as her disguise. Since Ruby's power is sustained from Eriol and not the moon, she loves to leech off of Touya's own power calling him her "delicious feast". She also makes it a point to get inbetween his relationship with Yuki, as she knows his secret.

Name: Spinel Sun

Eriol's second creation. Spinel Sun is his Sun Guardian and sustains himself completely as he, like Kero, derives his power from the sun. His only reason for being is to become Keroberos' sparring partner during the final battle.

Name: Spinel/Suppi

Suppi is Spinel Sun's false form. This name is actually a nickname that Nakuru called him once and when 'found out' by kero he used it as his Alias. Suppi loves sweets and gets hyper when eating them. Normally he is a calm character who enjoys reading in his free time.

Name: Clow Reed

Clow is Eriol's last incarnation. In the manga Clow split himself into two people, while in the anime he is reborn solely as Eriol. Being half chinese and english, Clow was the most powerful magician in the world. He was the creator of the Clow Cards, at the time, a new form of magic. He chose Sakura as his successor.

Name: Yue

The resident bishounen, Yue is the original creation of Clow, who is now Eriol. He was sealed away after Clow's death and reawoke as the guardian of the Clow Cards. Sakura becomes his new mistress and he becomes her Moon Guardian. If not for Sakura being his new mistress, Yue would have pledged his loyalty to Eriol, whom he recognized as his former master in one episode.

Name: Yukito Tsukishiro

Yukito is Yue's false form and is also not human. Yukito did not know of Yue's existance in the begining. Since his power is derived from his master and Sakura was not strong enough, Yuki was in danger of disaapearing. He was the object of affection for half the cast of CCS, while ultimately falling for Sakura's brother, Touya.

Name: Keroberos (Cerberus)

Kero is Clow Reed's second creation. He is Sakura's new Sun Guardian and was the one who trained and coached her from the beginning, although not in this form. He did not recieve his true form untill Sakura became the new mistress of the Clow Cards.

Name: Kero (chan)

This is Keroberos' false form. He was the guardian of the Clow book and was released in this form when Sakura first opened the seal. He remained in this form all through the first seasons untill Sakura became the new mistress and he could transform freely. Kero loves sweets much like Suppi and plays video games addictively.

Name: Fujitaka Kinomoto

Fujitaka plays an important role in the manga. He is the second half of Clow Reed's reincarnation. He is also Sakura's father. Eriol's goal is to split his power between himself and Fujitaka. This gives him the ability to see his dead wife, Nadeshiko. In the anime Fujitaka does not play this role and is just a simple architect/professor raising his kids.

Name: Sakura Kinomoto

Sakura is the main star of the show. By the time Eriol shows up she has become the new mistress of the Clow cards. He helps her transform the Clow cards into her own Sakura cards. In the end it is she who becomes his succesor.

Name: Syaoran Li

This kid's name is spelled so many ways because he's chinese. Anywhere from Shaolan to Xiao Lang. Anyhow he is Clow's direct descendant who possesses a great deal of power. In the Sakura cards arc he aids Sakura in changing the cards and ultimately falls in love with her. He is x-tremely jealous of Eriol and sees him as his rival, however he worshiped the ground Clow walked on in the beginning of the series (silly boy Clow and Eriol are one in the same!). He is very proud of his heritage and takes his duties seriously.

Name: Kaho Mizuki

27 year old Kaho, is every Eriol fangirl's nightmare. In the manga she is the final object of his affections. It is also rumored the same in the anime, although it is not directly stated. She is the only other female with magical powers in the series. She uses a bell that holds part of Clow's moon powers, which earlier aided Sakura in her judgement with Yue.

Name: Yamazaki Takashi

Yamazaki is not the most prominent character, he is more of a comic relief, being the class fibber. He has a wild imagination and loves to tell wild tales and stretching the truth to make it more interesting. He immediately becomes friends with Eriol when they muse together about tall tales, Eriol backing up and adding to his stories the whole time. Eriol hs been seen spending time with him, skiing, baking, swimming etc. In the anime, after Eriol left Tomoeda, Yamazaki never told another lie.
