The story of Sasa Haneda, known as "The VIP," began in autumn 2015 when the prominent catfighter made a splashy debut with Battle. At her induction press conference, she demanded a match against B-1 champion Yuto Akagi, but Battle scheduled her debut fight against an unknown rookie, Miri Kitami, aiming for a guaranteed victory. However, during the match, Kitami suddenly revealed a sadistic side, launching a fierce assault on Haneda and forcing her into a humiliating defeat. As a result, Haneda was made to publicly apologize, exposed in a disgraceful state. Overcoming that humiliation, Haneda rises once more, setting her sights on the Extreme Championship and holding a press conference—only for a new challenger to appear. It is Sayu Shatou, Haneda's own protégé who debuted under her coaching. Sayu directly petitions for a match against her master, but Haneda erupts in anger, insisting instead on facing Tsugumi Muto. However, Mariya Wakatsuki, the recent tournament winner, is deemed a more suitable opponent for Muto, and ultimately, the match is decided as the master-versus-disciple showdown Sayu desired. The bout will be held under Extreme Rules, with corrupt referee Jiro Abe officiating. At the start of the match, Haneda dominates what she considers an inferior opponent, but Sayu shows grit and desperately fights back. Surprised by the unexpected resistance, Haneda grabs a shinai and launches a weapon attack. She then demands the referee alter the rules to allow fouls, and Referee Abe complies. The match is officially changed to Extreme Rules, setting the stage for Haneda's victory. Will Haneda win this match and begin her march toward the Extreme Championship? Meanwhile, will Sayu be crushed under her master's weapon assault? With a lower-ranked opponent, a corrupt referee siding against her, and weaponized fouls in play, can Sayu prove her growth by defeating her master in this ultimate showdown?
