Takatsuki Yayoi is an idol from 765 Production. She is voiced by Nigo Mayako (仁後真耶子).
Yayoi Takatsuki, 13 years old, is very energetic, optimistic, and hyperactive at all times. Her strong will and optimistic traits are perfect for being an idol, though she frequently speaks too loud and sometimes can't control herself so that she is often hushed or punished by others, especially during school. She is also not the smartest of girls, hence the reason why she has low grades in school.
Yayoi loves to be of use and of help to others, doing housework and cleaning in the 765 Production building. She is also a good cook and prepares dinner and breakfast for her siblings when her parents are away from work.
Her family consists of herself, her father and mother, and her four siblings. Being the oldest of the five children, she looks out for her brothers and sisters and is very protective and fond of them, playing baseball with her brothers on her days off. She is closest to her younger sister Kasumi (霞).
Because of her father's unstable occupational status, her family is considered to be poor, and thus Yayoi often wears plain or baggy clothing and is living in a small house. Yayoi is also very greedy and self-conscious when it comes to finance; she occasionally asks the Producer to lend her money. Yayoi is said to never be good at video games. If she feels like she spent money on something useless, even down to just 10 yen, she will become extremely depressed and can stay in bed for days with her regrets haunting her.
