Madoka Kushitori, a third-year Samejima Academy student, captains the girls' kabaddi club. Her tall, athletic build, sun-tanned skin, and distinctly boyish appearance create a striking presence. She employs masculine language patterns and exhibits a bold, straightforward personality.

Her primary passion is kabaddi, though she later realizes her enthusiasm stems not from the sport itself but from the opportunity it provides for close physical contact with girls ranging from late elementary school age to fellow high schoolers. This motivation fuels her persistent recruitment efforts for the club. She directly challenges first-year students Chio Miyamo and Manana Nonomura to a match, intending to recruit them upon victory. Despite her skill and experience, she loses to Chio's unconventional tactics and clever strategies.

Following this defeat, Madoka intensifies her training regimen, referring to her solitary park workouts as "mountain training" despite the absence of mountains. This dedicated practice leads to technical refinement and self-discovery. She successfully recruits Chiharu Andō into the kabaddi club and expands her outreach by introducing the sport to elementary school girls from Eihei Girls' Academy, teaching them fundamental techniques. Her recruitment efforts significantly increase the club's visibility within the school community.

Madoka maintains a complex dynamic with junior club members, who both admire and fear her due to her energetic and bold approach. Her interactions are defined by straightforward honesty about her motivations and passionate dedication to club activities. Her character development centers on expanding the kabaddi club's reach while remaining transparent about her personal enjoyment of physical contact during gameplay.
