Mimi Sensei appears as an adult rabbit character adorned with a yellow bow, red glasses, a blue frock, and blue shoes. She fulfills the role of an elementary teacher guiding a recurring class of young animal pupils. Her debut occurred in the episode "Anpanman and Shokupanman," first broadcast on October 17, 1988. She and her students rank among the series' earliest and most enduring recurring figures. This consistent presence spans nearly every Anpanman theatrical film within the broader franchise.
