Tomoyo Daidouji

She has a group of bodyguards (all women) who protect her, but despite her economic status, she is a very kind, sweet, and gentle girl. She has no known physical abilities, but in return, she possesses countless talents, and thanks to these, she was able to become friends with Syaoran Li and Meilin Li. She is undoubtedly an invaluable friend; she knows her friends perfectly, helps Sakura in every way she can to capture the Clow Cards and then transform them into Sakura Cards, and is a great companion and source of strength.

She is the daughter of Sonomi Daidouji, the president of the Daidouji Toy Company. Sonomi was Sakura's mother Nadeshiko's cousin, making Sakura and Tomoyo second cousins.

Tomoyo is Sakura Kinomoto's best friend. When she discovers Sakura has magical powers and has become a Cardcaptor, she helps her friend. She designs costumes for Sakura and even Kero, in a wide variety of styles, depending on the card, and records their exploits on video whenever possible. Even though Sakura is generally happy about it, she only rarely makes a real effort to stand out, as she naturally looks good in action. Despite this, she often gets quite exasperated when it becomes clear that Tomoyo is going to record her and self-conscious when she watches the recordings.

She finds Sakura's quest very exciting, so she makes various dresses for her to wear while capturing the Cards and also records all her adventures on video, although she regrets not having recorded some captures.

Very occasionally, her behavior has been seen to reveal a degree of melancholy, and even a bit of emotional tension, when a recording doesn't turn out as perfect as she would have liked, or she mentions the effort she has to make to ensure her recordings turn out well. This indicates that, despite constantly stating that she loves recording Sakura and putting in the effort (both in relation to filming her, editing her films, and making her costumes) to ensure her films are of very good quality, all the effort these tasks entail puts her under a certain degree of tension or stress, which makes her react in a somewhat "dark" way when her expectations are not fully met.

Tomoyo's skin is porcelain white, her hair is grayish-violet, and her eyes are purple. Her bangs are wide, covering her entire forehead and partially obscuring her short eyebrows. Her hair is long, reaching down to her lower back, and ends in several wavy extensions. This is because her mother, deeply grieved by the death of her cousin Nadeshiko, wanted her daughter to resemble her, so she grew her hair that way, although later on, we see Tomoyo sporting various hairstyles.
