How Berthier joined the Tourney
Berthier is the first sister sent by Rubeus to take over Crystal Point in Tokyo. She has two solo missions and the droids she used were Atsugessho and Nipasu.
After Koan left the Ayakashi family, Rubeus sent Berthier to take over a crystal point in a chess building. Ami Mizuno encountered Berthier and transformed into Sailor Mercury to fight her, revealing her true identity to her. Berthier retreated from the battle and entered the chess tournament where she faced Ami in the finals. Although Ami won, Berthier trapped the other Sailor Senshi in a ball of ice and started another game of chess with Ami, except this one was with her own rules - whenever Ami lost a piece, a part of her body would freeze. The spell was shattered by Tuxedo Mask, who freed all the Sailor Senshi and Berthier's plan was foiled. Calaveras and Petz had appeared to reclaim some of the credit when Berthier's had the advantage but explained that Rubeus was going to kick her out for her failure and abandoned her. Berthier, alone and out numbered, broke down and attempted to freeze herself and the entire Senshi to death. Kōan convinced her to stop and change her evil ways so Sailor Moon used Moon Crystal Power on her.
Berthier was later captured along with Koan by Calaveras and Petz, in an attempt to turn them evil again but in the battle that followed, Rubeus ditched Calaveras and Petz and they were also healed of their evil. Berthier is the second of the Ayakashi Sisters to turn good.
A month after the Black Moon Clan's defeat, the Spectre Sisters are encountered by a being made of fire. He told them that his premonition of a looming conflict was near, the conflict being the second Tourney. This being, Blaze, gave the Spectre Sisters back their powers, and orders them to fight for good. On Berthier's way to the Tourney, she finds herself being flirted on by a young man named Terunosuke Miyamoto.
