She is an elementary school student at Tomoeda Elementary School. There are three members in the family: a kind father, Fujitaka, who makes delicious snacks, and an elder brother, Toya, who looks a little mean but is really considerate. Her mother, Nadeshiko, passed away when Sakura was 3 years old, but the three of them live happily together and cooperate with each other. She is a cheerful and energetic normal girl who belongs to the cheerleading club and uses inline skates to go to school, but one day, at the request of Cerberus, she suddenly decided to become a card captor who collects clow cards containing magical powers.
