Sakura is an extremely energetic and cheerful character. She is very athletic, being a member of her school's cheer leading squad and an excellent runner. Her "invincible spell," "Everything will surely be all right." (「絶対大丈夫だよ。」, "Zettai daijoubu da yo."), has carried her through innumerable trials and obstacles as she masters her magical skills. She often comes across as naive, clumsy, and clueless, but she has her perceptive moments on occasion.
Sakura's optimistic and trustworthy character allows her to befriend virtually everybody, and the series focuses on the friendships she creates with people, whether strangers, loose acquaintances, or rivals.
Sakura was selected by Kerberos, to capture all the Clow Cards she set loose, and when capturing the cards, a rival in the form of Syaoran Li appears. At first, Syaoran is unfriendly and views her as an annoying rival, but her cheerful personality allowed him to become a good friend, and even fall in love with her. Her brother, Toya Kinomoto also has a sister complex and so he is always an enemy to Syaoran.
In Tsubasa Chronicle, she gave her star staff to the mother of 'Syaoran', for either to share her power and give it to the Witch of the Dimensions as price to transport 'Syaoran' to Clow Country.
