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

Syaoran Li: Has a high-strung, slightly prickly, boyish way of speaking. First person: I (Ore). Initially, he was antagonistic toward Sakura and called her "you" (omae), but now they are close and he calls her "Sakura" without honorifics. He often gets jealous when Eriol and Sakura are talking. In the Sakura Card arc, the sharp "bratty rival" attitude from the Clow Card arc is completely gone; instead, he speaks with the fresh, innocent tone of a boy who stammers and makes frantic excuses out of nervousness whenever he's around Sakura.

Tomoyo Daidouji: Speaks with an elegant, refined tone that reflects her high-class upbringing. First person: I (Watashi). She calls Sakura "Sakura-chan" and speaks in a gentle, calm tone, often ending sentences with polite forms like "-desu wa" or "-masu wa." She calls Syaoran "Li-kun," Keroberos "Kero-chan," and Yue "Yue-san."

Eriol Hiiragizawa: Speaks in an incredibly gentlemanly, calm, and polite manner that belies his elementary school age. He always speaks with a tone that suggests a composed smile, using polite language to address others kindly. He adds "-kun" for boys and "-san" for girls to their surnames for everyone except Sakura. He calls Sakura "Sakura-san."

Touya Kinomoto (Big Brother): Speaks in a low-pitched, blunt, and somewhat unsociable young man's tone. First person: I (Ore). He teases Sakura by calling her "Monster" (Kaiju). However, despite his bluntness, he speaks with a caring and kind tone toward Yukito and those around him. He is very devoted to his sister. He works many part-time jobs.

Keroberos (Kero-chan): In his temporary form, he speaks in a thick Osaka dialect (Kansai-ben) he picked up from watching TV. His catchphrases include "-yagana," "-yanka," and "Nanyate!?" (What!?). When he returns to his true form, his tone shifts completely to a dignified, low-pitched, and cool adult male voice. Since he must not be exposed to humans, he stays home while Sakura is at school.

Yukito: Speaks in an extremely gentle tone, always smiling and using soft sentence endings like "-da ne" or "-da yo" with everyone. Yue: Speaks in a cold, detached, and blunt tone that shows no emotion. First person: I (Watashi). Even toward his new master, Sakura, he initially called her "you" (omae) and treated her strictly. Now, that is not the case at all. He is male.

Nakuru Akizuki: Speaks in a high-energy, modern gal-like explosive style. She often uses a sweet, clingy tone while shouting "Touya-kuuuun!"

Spinel Sun (Suppy): Speaks in a very serious, cold, and intellectual polite tone. He calls the frivolous Kero-chan "you" (anata) and treats him coldly. However, if he eats something sweet and gets "drunk," he goes out of control, speaking in baby talk and a frivolous tone even worse than Kero-chan's.

Kaho Mizuki (Ms. Mizuki): Speaks in a graceful, very calm, and mysterious tone, as if she sees through everything. First person: I (Watashi). She addresses Sakura and the others by their surnames with honorifics, like "Kinomoto-san" and "Li-kun." She calls her former lover, Touya, by his first name without honorifics. Her speech is based on slow, gentle, polite language that exudes adult composure. When Sakura is troubled or confused by a Card's presence, she smiles gently and says, "It's alright, everything will surely be fine," as if prophesying Sakura's invincible spell. When talking to Eriol: In front of Eriol, who is Clow's reincarnation, she speaks in a slightly more relaxed and soft feminine tone as an equal who knows his plans and true identity (and later becomes his lover). She usually uses gentle sentence endings like "-ne," "-yo," and "-da wa."
