Blanca is Vanilla's magical familiar. She is a mouse and dislikes being called a rat. She is extremely helpful to Vanilla, offering advice on how Vanilla can gain more hearts. Blanca loves Vanilla and openly hates Chocolat, often laughing at Chocolat's plans. She ends her sentences with "-chu," which mimics the sound of a mouse in Japanese.
In the manga, she used to run a salon in the Magical World but was transformed into a familiar when she fell in love with a human and lost her heart. She regains her original form with the power of Pierre's (now white) heart. Her real name in English is Libbie or Libby, and Blanca means "white" in Spanish (feminine form of blanco).
