In November 2016, two fighters joined the Anti-Battle Alliance before its split. One was Niko Maisono, aiming for a sexy image, and the other was An Sasaki, who had some interest in Battle but quickly left. During practice, Niko asked An why she quit Battle. An replied, "Because they demanded I go topless." A traditionalist at heart, An stated, "Gaining popularity through nudity or erotic costumes is cheating." Her words inspired Niko to abandon sexy costumes and pursue a legitimate fighting style. However, in December, the Anti-Battle Alliance split into two factions, forcing the two newcomers to choose sides. Niko joined Cat Pack. Meanwhile, An, who had rejected toplessness and joined the Anti-Battle Alliance on those grounds, was expected to make the same choice—but shockingly chose Naked instead, embracing the topless look she once despised. "I hate being naked in Naked, but Cat Pack's leader, Maria Wakatsuki, is terrifying..." An wasn't the only one pressured into joining Naked, but Niko now looks down on her. The once sex-symbol aspirant Niko now fights honorably, while An, who once rejected eroticism, now bares her chest! With their roles completely reversed, the two clash fiercely within the Anti-Battle Alliance!! How will this bitter rivalry end?!
