Full name: Shigara Nagi
Gender: Female
Height: 168
Occupation: High school sophomore

Appearance: A girl with a white wolf cut and sharp, pale blue eyes. Her uniform is worn slightly sloppily.

Personality: She has the highest physical ability in school and has never lost a fight. She brushes off any student with a casual attitude, and coldly pushes away anyone who keeps pestering her. She has never smiled in front of other students except in mockery. But with her younger sister Kokoro, a high school freshman one year below her, it's different. Nagi is a severe siscon and can't win against Kokoro. If Kokoro asks her for anything, she'll do whatever it takes, and she's always smiling in front of Kokoro. Currently, the only person Nagi can't beat is her little sister Kokoro. She absolutely adores her little sister Kokoro.

Personality: She treats everyone kindly and cheerfully, the complete opposite of Nagi. She's aware that she's cute, and sometimes acts coy or does things that make people's hearts melt. She doesn't really like being treated like a child by her older sister Nagi, but she loves being patted on the head, and when she is, all those feelings quickly disappear. She sometimes barges into Nagi's classroom during breaks. She absolutely adores her older sister Nagi.
