Description
Minatsu Shiina is a second-year student at Hekiyou Academy and serves as the vice president of the student council in Student Council's Discretion Lv. 2. She is the older sister of Mafuyu Shiina, the council treasurer. Minatsu is a tall girl with brown hair and blue eyes, standing 166 centimeters. She first met Ken Sugisaki during summer break after her first year of high school, and that meeting inspired him to work hard and improve himself. Her background includes a close relationship with her younger sister, whom she is very protective of and will strongly oppose anyone who tries to hurt Mafuyu.

Her personality is that of a classic tomboy and a tsundere. She is bold, energetic, and always ready to take action, especially when it involves shonen anime or manga, which she is passionate about. She frequently suggests ideas based on typical shonen storylines. Despite her athletic and action-oriented nature, she is surprisingly good at mathematics, a contrast that Ken finds notable. She harbors romantic feelings for Ken but struggles to admit them openly, often denying her affection in a tsundere fashion. She is popular among other female students at the school.

Her motivations include protecting her sister, enjoying her time with the student council, and gradually coming to terms with her feelings for Ken. She is driven by a desire to act decisively and often serves as the council's physical and enthusiastic force.

In the story, Minatsu plays the role of the energetic and sporty vice president. She participates in the council's daily meetings and comedic activities, often injecting a shonen-inspired, action-oriented perspective into discussions. Her relationship with Ken is a central subplot: she is in love with him but conceals it behind a tsundere facade, and in the second season she takes a significant step by kissing him. Her bond with her sister Mafuyu is also important; she is protective and caring, though Mafuyu's own quirks often cause Minatsu to worry. She interacts with the other council members—president Kurimu Sakurano, secretary Chizuru Akaba, and her sister Mafuyu—as part of the group's dynamic.

Over the course of the series, Minatsu's character develops slightly as she becomes more willing to show her feelings for Ken, though she remains fundamentally a tsundere. Her protective nature toward Mafuyu and her love for shonen media are consistent traits.

Her notable abilities include exceptional athletic skills, making her nearly unbeatable in any sport. She also possesses unexpected academic skill in mathematics, and her enthusiasm for shonen manga often leads to creative, action-heavy suggestions for student council activities.
