Asawo Kurikoma is a second-year student at Miyagi Prefecture's Sōshūkan High School, also known as Ao High School. She serves as manager for the school's men's rhythmic gymnastics club. Her consistently neutral expression makes her thoughts difficult to read, yet she possesses strong observational skills, accurately pinpointing club members' strengths and weaknesses. This ability earns her significant trust within the team.

Her technical expertise is crucial to the team's support. She employs 3D modeling software on her tablet to simulate and explain gymnastic performances, helping members visualize and refine their techniques. She also designs the team's competition costumes.

Asawo is related to the team's coach, Shūsaku Shida. Shida's wife affectionately calls her "Asachan," though the team has never met her.

She has neck-length maroon hair styled with bangs swept to the left and blue eyes. Her standard attire is the school uniform: a light grey blazer, white button-up shirt, dark grey sweater vest, navy blue skirt with a red stripe, white socks, and brown loafers. During club activities, she wears a turquoise and white track jacket, blue shorts, white socks, and turquoise and white tennis shoes. Her pink tablet is a near-constant accessory.

Her portrayal remains consistent across the television series, manga adaptation, and theatrical film, maintaining her role as a technically skilled and observant manager without significant character development arcs or expanded background details.
