Berthier

Berthier is the second-youngest sister. Her name is French, coming from the mineral berthierite, and is pronounced roughly as "BEAR-tyay." Her magical attack is called "Dark water" and she is a counterpart of Ami Mizuno. She fears Rubeus but has no love interest for him unlike her other sisters. In the manga, Berthier is given the mission "Code002, Operation Re-move" to kill the Sailor Senshi and capture Chibiusa. She disguises herself as a normal human and wows people with her dowsing abilities using a pendulum. In the anime, Berthier has a very darkly playful personality, but is shown to have great respect for all of her siblings. She is the only one shown to be upset when Cooan is purified by the Silver Crystal. Much like her counterpart in Ami, she is also a strategist and is incredibly talented at chess, though she apparently also cheats.
