Misaki began wearing the bear costume at her part-time job and she was reluctantly roped into joining the band by Kokoro.
Michelle is a fluffy pink bear costume with white facial detail and paws. Michelle's eyes are big and shiny, and her mouth is fixed to be opened in a cat smile. Michelle wears a matching uniform of her band mates, with the addition of fuzzy purple headphones with a black and gold center.
- Misaki, due to Kokoro, Kaoru and Hagumi, has also had to come up with a story and personality for Michelle at multiple times. Some examples of said story are:
- Despite described as a bear, most people are confused at what Michelle really is. (Himari thinks Michelle is a dog, Hina thinks Michelle is a lion, while Yukina at one point thinks Michelle is a cat).
- Michelle is shown to be somewhat of a mascot character in the in-game universe.
- For the Persona collaboration, if players logged in during the campaign period they received a new Michelle costume, which was based on Mona.
- For the Gochiusa collaboration, players also received a new Michelle costume, which was based on Takahiro Kafuu's design.
