Mimi Sensei is an adult rabbit character who wears a distinctive yellow bow, red glasses, a blue frock, and blue shoes. She teaches a recurring group of young animal students at an elementary school. Debuting in the episode "Anpanman and Shokupanman" on October 17, 1988, she stands as one of the franchise's earliest and most frequently featured characters. Mimi Sensei maintains a consistent presence throughout the anime series and appears in nearly every Anpanman movie, including the 1991 film "Tobe! Tobe! Chibigon" where she is credited as a minor character. Her portrayal consistently reflects her role as an educator overseeing young pupils. In the Tubi English dub adaptation, she is known as Miss Mimi.
