The battle is on! Berthier challenges Ami to a game of chess, and then seals Usagi, Rei, Makoto, Minako and Koan away. She gives Ami one pawn to play, and tells Ami if she loses her friends will die. Ami thinks hard, but cannot win! She beats Berthie... (more)r, and Ami's friends are saved. Calaveras and Petz come down, and tell Berthier she is useless and they don't want her back in the Three Sisters Clan. Berthier attempts suicide (by freezing herself) but decides to convert good, when her sister Koan convinces her too.
