Poppu Harukaze

Poppu is the red witch apprentice. She is Doremi's little sister. She is more of a minor character. In the English dub she is Caitlyn Goodwyn and in another country, she is Bibi. She is very bossy and acts older than Doremi, even though she is quite the opposite. She becomes a witch apprentice after she discovers that Doremi is one in Episode 25.
