Minami Kinoshita, vice-president of the Prince Yuki Fan Club at Kaibara Municipal High School, possesses a headstrong and fiercely devoted personality, particularly toward Yuki Sohma. Her light brown hair is often secured in high pigtails with pink elastics, and her light brown eyes complement the standard school uniform she wears, adorned with a small gold pin.

She spearheads fan club activities focused on protecting Yuki, directing significant hostility at Tohru Honda due to Tohru's closeness to him. Minami collaborates with members like Motoko Minagawa and Mio Yamagishi to undermine Tohru, though their schemes are frequently disrupted by Tohru's friends Arisa Uotani and Saki Hanajima, whom Minami fears. This includes a failed visit to Saki's home under false pretenses, where Saki and her brother Megumi exposed their intentions. Minami also bullies other girls associated with Yuki, such as Machi Kuragi, resenting Machi's indifferent attitude toward him.

During the school play *It's Cinderella-ish*, Minami played the wicked stepmother—a role originally meant to cast Tohru negatively. Script changes occurred due to Tohru's inability to portray meanness, but Minami retained her antagonistic part, believing it suited her. Within the fan club, she shares camaraderie with Motoko, frequently squabbles with Mio, and assumes leadership duties in Motoko's absence, aspiring to become the next president. Outside the club, she harbors strong animosity toward Tohru, whom she labels a "witch," and Kimi Toudou, though Kimi dismisses her harassment. Minami's zodiac sign is the Tiger, making her the sole fan club member with a confirmed zodiac association.
