President of the Gymnastics Club. 3rd year. A hard worker with strong leadership. While she can be a bit of a klutz, her dedication makes her beloved by all members, who unite to support their president.

Vice President of the Gymnastics Club. 3rd year. Calm and composed, she is highly trusted for her support of the president. She and the president have been best friends since childhood. She occasionally exudes a sensual aura, and the president often has to drive away men who flock to her. She has a younger sister in the club. Being an older sister, she has a very caring personality.

2nd year. Mixed-race of European descent. She lived abroad until a few years ago but moved to Japan for her parents' work. She happily joined the gymnastics club, glad to continue the sport in a high-level environment. She speaks Japanese fluently as her parents use it at home. Perhaps due to her international background, she is often bold with skin exposure, sometimes to the point of flustering those around her. However, having grown up reading Japanese shojo manga, she is surprisingly shy when it comes to romance.

2nd year. The mood maker. She tries desperately to look cute but often ends up failing and getting awkward smiles from those around her. She gets embarrassed when genuinely called cute, so she acts out to hide her shyness. In terms of gymnastics, she is the hidden ace. Once her performance begins, she displays a level of focus unimaginable from her usual self. Through hidden effort and intense concentration, she scores high when it matters most. The other members know about her hard work, so they overlook her usual goofing around.

1st year. Her older sister is the vice president. She has been close with her sister and her sister's best friend since she was little. She started gymnastics to keep up with the two of them. Although she is two years younger, she is a natural genius whose skills rival theirs. The Gymnastics Association is already keeping an eye on her rapid growth. Recently, she has unconsciously started acting in a "calculatedly cute" way, which makes her sister feel a bit uneasy.
