Once again, the fighting female warriors return for another intense battle tournament!! Watch as these beautiful, well-toned bodies charge into combat without concealment—the highlight being their fearless, bare-chested charge onto the battlefield!! The chaotic close-quarters combat opens once more!! As the topless tournament returns this year, Kawanishi Ami, having overcome last year's tragedy, begins a new fight. After her younger sister, Kawanishi Hitomi, was defeated and sexually dominated by the depraved lesbian rapist, Hara Chigusa, Ami establishes the Anti-Battle League, significantly impacting the future of the tournament. This year, fighters are increasingly pressured to compete topless, causing more to join the Anti-Battle League and making it harder to secure participants. Amid this, BATTLE approaches Otoha Leon and Wakatsuki Mizuna to join. Both naturally refuse, but accept a condition: if they win the mixed match, they enter the Extreme Tournament; if they lose, they must compete in the topless tournament. In the end, both lose their mixed matches and are forced into the topless tournament. Though neither enters with enthusiasm, what will become of this fierce battle!? An I-cup giant-breasted fighter joins the fray as well!! Her proud, voluptuous breasts sway with every move, merging eroticism and combat into a shocking spectacle!! The topless hand-to-hand combat awaits!! The battle begins now, with sweat-drenched cleavage pressed tight and full-on sexual attacks unleashed!!
