Sakura Kinomoto: Speaks in a cheerful, energetic, and childlike manner. Refers to herself as "Sakura" and addresses others as "-kun" or "-chan." Her main catchphrases are "Hoe~!" when surprised and "Hanya?" when confused. When encouraging herself, she says, "Everything will definitely be alright." She generally adds -kun or -chan to first names. She calls Yukito "Yukito-san," Yue "Yue-san," and Keroberos "Kero-chan." She is a girl full of courage when it comes to the cards. First person: I (Sakura).

Syaoran Li: Speaks with a high-strung, slightly prickly boyish tone. Refers to himself with "Ore." Initially, he called Sakura "you" (blunt) and was antagonistic, but now they are close and he calls her "Sakura" without honorifics. He often gets jealous when Eriol and Sakura talk. In the Sakura Card arc, the sharp "insolent rival" attitude from the Clow Card arc is completely gone; he becomes a bashful boy who stammers and makes excuses when he's nervous around Sakura. First person: I (rough, boyish).

Tomoyo Daidouji: Speaks with an elegant, refined tone that shows her high-class upbringing. Refers to herself as "Watashi." She calls Sakura "Sakura-chan" and always ends her sentences with polite, gentle flourishes like "-desu wa" or "-masu wa." She calls Syaoran "Li-kun," Keroberos "Kero-chan," and Yue "Yue-san." First person: I (polite, feminine).

Eriol Hiiragizawa: Speaks in an extremely gentlemanly, calm, and polite tone that belies his elementary school age. He always speaks with a smile that suggests he has room to spare, using polite Japanese to gently address others. He adds -kun to boys' surnames and -san to girls' surnames, except for Sakura, whom he calls "Sakura-san." First person: I (polite).

Touya Kinomoto (Big Brother): Speaks in a low, blunt, and somewhat unfriendly young man's tone. Refers to himself with "Ore." He teases Sakura by calling her "Monster." However, he speaks to Yukito and others with a blunt but caring and kind tone. He cares deeply for his sister. He works many part-time jobs. First person: I (casual, masculine).

Keroberos (Kero-chan): In his temporary form, he speaks with a thick Osaka dialect (Kansai-ben) he picked up from TV. His catchphrases include "-yagana," "-yanka," and "Whaaat!?" In his true form, his tone shifts to a dignified, deep, and gravelly adult male voice. Since he must not be seen by humans, he stays home while Sakura goes to school. First person: I (casual/dialect).

Yukito: Speaks in an extremely gentle tone, always smiling and using soft sentence endings. Yue: Speaks in a cold, detached tone that pushes others away, showing no emotion. Refers to himself as "Watashi." Even toward his new master, Sakura, he was initially harsh and called her "you" (blunt). That is no longer the case. He is male. First person: I (polite/cold).

Nakuru Akizuki: Speaks with the high-energy, bubbly tone of a modern gal. She often clings to Touya while shouting "Touya-kun~~!" in a sweet, playful voice. First person: I (energetic).

Spinel Sun (Suppy): Speaks in a very serious, cold, and intellectual polite tone. He calls the frivolous Kero-chan "you" (formal) and treats him coldly. However, if he eats something sweet and gets "drunk," he goes wild with baby talk and a rowdy personality even worse than Kero-chan's. First person: I (formal).

Kaho Mizuki (Ms. Mizuki): Speaks in a graceful, very calm, and mysterious tone, as if she sees through everything. Refers to herself as "Watashi." She calls Sakura and the others by their surnames with "-san" or "-kun." She calls her former lover, Touya, by his first name without honorifics. She uses gentle, slow polite speech. When Sakura is troubled by the presence of a card, she smiles and says, "It's alright, everything will surely be fine," as if prophesying Sakura's invincible spell. When talking to Eriol (Clow Reed's reincarnation), she speaks as an equal who knows his plan, using a slightly more relaxed, soft feminine tone. First person: I (polite, feminine).
