The elite all-girls Wild's Private High School has bred some of the strongest and most renowned martial artists in the world. To help foster these skills, the school hosts the Wild's League, a brutal martial arts tournament where only the strongest fighters prevail. Reigning above all other students is the current champion "Queen," a beautiful S-Class mixed martial artist named Yoon In Gyi, who has mastered various forms of fighting.
