Akane

Guest character in episode 15 of the anime. A girl who stays home alone because her mother is working. She mistakes Keroberos, who was camping out after a fight with Sakura, for a cat and takes him home, naming him "Chau-chan" after mistaking his utterance of "chau" (meaning "different") as a meow. She moves away from Tomoeda Town due to her mother's job change.
