Berlitz is the female protagonist for the Pokémon Diamond and Pearl story arc of Pokémon Adventures. Berlitz comes from a 200-year old family of wealthy scholars famous in Sinnoh. She wears pearl and diamond rings. She does not give her name to commoners; therefore, Berlitz's given name is unknown. The Berlitz family tradition is for members coming of age to travel to the peak of Mt. Coronet to obtain materials to make their personal family crest. Wikipedia
