Sakura (サクラ) is the princess of the Kingdom of Clow, who befriends and falls in love with Syaoran during her childhood. She is stripped of her memories and magical abilities by a powerful force, which take the form of feathers, and they are spread all throughout different dimensions. In order to save her life and retrieve the feathers, she and Syaoran are sent to Yūko, who gives them the use of Mokona in exchange for Sakura's memory of Syaoran, which causes him to be absent from any memories restored to her. She is initially weak, confused, and constantly tired, but she grows stronger as she regains her feathers. She is very friendly with Fai and Mokona, she grows close to Syaoran again, and she notices that she is missing something from her memories. Sakura possesses unnaturally good luck; Yūko calls her "God's favorite daughter." Sakura also has the ability to "hear" the voices of those who cannot be heard, such as spirits of nature, and to see ghosts.
Syaoran (小狼, Shaoran) is a resident of the Kingdom of Clow, who meets and falls in love with Sakura. He is the adopted son of Fujitaka, who found him in the street. He often accompanies his father on expeditions, and while in the Clow Kingdom, he spends most of his time with Sakura. After Sakura's memories are scattered, he makes it his goal to find them, even at the cost of their relationship. He eventually starts to lose control of his body at certain points, and his personality completely changes. It is eventually revealed that he is a clone of the original Syaoran(Tsubasa), meant to be a mindless doll controlled by Fei Wang. Syaoran manages to place some of his "heart" within the clone's right eye, which allows him to become his own person. After the seal breaks, he is used by Fei Wang to collect feathers, but he comes to his senses after killing Sakura. He is killed after he betrays Fei Wang, but he is reincarnated into Syaoran, living in another dimension.
Fai D. Flourite (ファイ・D・フローライト, Fai D. Furōraito, also romanized as Fay D. Flowright) is a powerful magician from the country of Celes. He travels to Yūko on his own accord after sealing King Ashura of Celes and having his creation, Chī, act as a barrier to alert Fai if Ashura awakens. He wishes never to return to Celes and have the ability to run away through dimensions if Ashura does awaken, so he gives up a tattoo on his back in order to have use of Mokona. Fai is a very enigmatic person. He appears to be happy-go-lucky and good-natured, and acts very carefree. He often teases Kurogane, calling him ridiculous nicknames such as "Kuro-rin", "Kuro-tan" and, in the English version, "Kurgy". Kurogane questions this nature, sensing that it is just a false persona to hide that he is emotionally distant, and Fai usually gives very dark and enigmatic answers if asked about it. Fai doesn't bother to fight very hard for his life, and will only do so if someone he cares for is in danger, which Kurogane notes to be Syaoran and Sakura, as the group bonds.
Kurogane (黒鋼, lit. "Black Steel") (Birthname: Hikenomonu)is a rough-mannered ninja from the world of Nihon (ニホン, lit. Japan), who is sent away from his world by Princess Tomoyo in order to have him discover true strength. He is the most powerful warrior in his world, but he shows no mercy to anyone, even at Tomoyo's request, so she places a "curse" on him that will decrease his strength if he kills anyone. He gives up his sword,"Ginryū" (銀竜; Japanese for Silver Dragon), as the price to use Mokona to cross dimensions and return to his home world. He quickly bonds with Syaoran, who he trains in swordsmanship and helps overcome his blind right eye. He is constantly teased by Fay, who calls him a variety of nicknames, though he also is able to tell Fay's true nature, and Mokona, whose cute nature Kurogane cannot stand, preferring to refer to Mokona as a "white pork bun." or "white manju bun." Though he initially has no interest in helping restore Sakura's memory, he eventually finds himself risking his life for the group.
Mokona Modoki (モコナ＝モドキ) refers to two rabbit-like creatures created by Yūko Ichihara and Clow Reed in preparation for the events in Tsubasa: Reservoir Chronicle and xxxHolic, as well as to stop Fei Wong Reed's plans and save the "two futures". The white Mokona travels with Syaoran's group, while the black Mokona stays in Yūko's shop. Both are based upon the original Mokona, who Yūko and Clow encountered while Mokona was traveling through different worlds. Mokona provided Yūko and Clow with the knowledge of alternate dimensions.
