Bianca

Bianca is a flighty girl who, in her own admittance, is a little on the air-headed side. Despite having a polar opposite personality, she frequently tags along with Hilbert, Hilda and Cheren, as the four of them are longtime friends. She is Hilda's roommate, and the two of them share a sister-like relationship.

Bianca was first introduced in Pokémon Black and Pokémon White versions.
