Asawo Kurikoma is a second-year student at Sōshūkan High School, also known as Ao High, where she serves as the manager of the boys' rhythmic gymnastics club. Originally from Miyagi Prefecture, she is one of the few female characters prominently featured in the story.

Asawo often presents a calm and expressionless demeanor, which can make her thoughts difficult to read. Despite her reserved exterior, she possesses exceptionally keen observational skills, allowing her to accurately assess the strengths and weaknesses of each club member. Her insights are not merely intuitive; she applies a methodical and technical approach to supporting the team. She is highly skilled at creating performance simulation videos using 3D models, a crucial tool that helps the gymnasts visualize and refine their routines. Furthermore, Asawo is responsible for designing the team's competition uniforms, a task that showcases her creativity and attention to detail. These practical contributions have earned her a high level of trust and respect from the rest of the club.

In terms of personal connections, Asawo is a relative of Shuusaku Shida, the team's coach. Her relationship with the coach's family is warm, as she is affectionately nicknamed "Asachan" by Shida's wife.

While her calm and analytical nature is her defining trait, Asawo also displays a down-to-earth and unflappable personality. In one notable incident, she presented new uniform designs to the team. As several of the boys excitedly began changing clothes on the spot before remembering she was present, a typical response might have been one of shock or embarrassment. Instead, Asawo pulled out her phone and began taking pictures of the shirtless gymnasts with unabashed enthusiasm. This moment underscores that she is not a shy or overly sentimental character but rather a normal teenage girl who can be appreciative of her surroundings, all while maintaining her typically composed and professional exterior.
