Minami Kinoshita is a second-year student at Kaibara Municipal High School and a minor supporting character in Fruits Basket. She serves as the vice-president of the Prince Yuki Fan Club, a group of students who idolize Yuki Sohma, and is next in line to become its president after the current leader, Motoko Minagawa. Minami is also a classmate of the protagonist, Tohru Honda, and holds the position of class vice-president.

Her defining trait is her intense adoration of Yuki, which drives her possessive and competitive behavior. She is the most outspoken member of the fan club, often taking the lead in verbal confrontations against any girl she perceives as a threat to Yuki’s image or her own proximity to him. This puts her in frequent conflict with Tohru, who is close to Yuki. However, Minami’s aggressive efforts are consistently thwarted by Tohru’s protective friends, Arisa Uotani and Saki Hanajima, who easily outmatch her in these exchanges.

Minami’s role in the story is primarily comedic and antagonistic in a lighthearted sense, highlighting the exaggerated fandom culture within the school. She participates in school events, such as portraying the wicked stepmother in the play "Sorta Cinderella." Her character does not undergo significant development or growth; she remains a steadfast enthusiast of Yuki throughout the series, serving as a minor obstacle and a foil to Tohru’s gentle, unassuming nature. Her notable abilities are limited to her vocal assertiveness and her leading role within the fan club hierarchy, which she uses to coordinate group actions against perceived rivals.
