The fight begins when Gauche notices that Marie has a mark on her cheek and attacks Neige. Baro wonders how they were found out so fast and tells Neige to attack. Neige attacks with Snow Cry but Gauche easily dodges all of the attacks. Neige counters by creating an army of snowmen to attack but Gauche easily destroys them all. Baro thinks about how he has not finished his work yet and wonders how much mana Gauche has. Neige asks Baro what to do, and Baro tells him to think for himself.
Gauche finishes destroying Neige's army and asks if that is all Neige has. Neige manages to restrain Gauche with Snow Lime Rock but Gauche's Real Double attacks him from behind. Gauche's double frees the original while Neige lies on the ground defeated and confused.
Gauche walks up to Neige and kicks his head as the Knight plans to kill him for hurting Marie. Theresa and Marie plead for Gauche to stop, but he refuses. They are interrupted by the arrival of Sally.
