After breaking up a catfight between two scantily-clad brawlers, Aya finds herself involved in an underground martial arts tournament.

Aya battles a curvy chemistry teacher and neither wants to mess up her opponent's pretty face.

Aya battles a naughty policewoman and, later, takes on three sexy sisters.

While her new look drives the crowd wild, Aya only cares about punishing her opponent in the semifinal match.

Aya reaches the final round of the tournament, but she'll have to defeat a clairvoyant opponent to win the Platonic Heart.
