Tomoyo is the best friend of Sakura. When she discovers that Sakura has become the Cardcaptor, she becomes Sakura's primary assistant by designing "battle costumes", and filming all of her magical (and non-magical) endeavours. (The videotaping, however, seems to be more to Tomoyo's personal benefit and enjoyment than it is to Sakura's.) Tomoyo faithfully keeps Sakura's new identity secret and often covers for her in times of need.

Tomoyo is the daughter of the president of Daidoji Toy Company, Sonomi Daidoji (Samantha Taylor). Sonomi and Sakura's mother Nadeshiko Kinomoto (Natasha Avalon) are first cousins, which makes Sakura, Toya and Tomoyo second cousins. Tomoyo's father is never shown in the series and is only alluded to once, but it is apparent that he does not live in the Daidoji household. Her western-style house in Tomoeda is quite grand, with several maids serving the household. She is sometimes attended by the Daidoji family's team of female bodyguards, and has access to prototype technology from her mother's company (including the cell phones she supplies to Sakura and her circle).

Tomoyo is very mature for her age. One of her major character traits is her selflessness towards Sakura. Tomoyo is kind, caring, highly intelligent, beautiful, meticulous, and very melodic (she has a superb singing voice and often has solos in choir recitals). She always speaks using formal verb conjugations and expressions, giving her a unique air of refinement amongst the cast. When needed, Tomoyo can exhibit considerable cunning and resourcefulness.

Tomoyo aids Sakura's efforts to be in the company of Yukito Tsukishiro (Julian Star) on many occasions, and, in the second half of the series, becomes the confidante of Syaoran Li (Li Showron) when he finds himself falling in love with Sakura.
In the english version Cardcaptors, the fact Sakura and Tomoyo were second cousins was erased from the story, mostly due to the network passing over the episode where Sakura and Tomoyo discover the fact they are cousins.
