A slender girl seriously devoted to sumo challenges herself in mixed-gender sumo, where men's rules apply. Though petite and often overpowered in strength matches, her fighting spirit never wavers. In this production, instead of women's regulations, she competes under men's rules—wearing only a mawashi, fully topless. Each time she engages in sumo, male hands inevitably grope her breasts, sparking one erotic incident after another. Helpless against powerful throws and lifts, her most intimate moments are exposed. When she desperately locks into a grappling stance, her opponent's legs rub against her crotch, leading to increasingly erotic and fetishistic situations. This sexy sports drama lets you enjoy the determined struggle of a female sumo wrestler pushing her limits. [Mayama Gekijiro]
