Cinnamon is the third youngest catgirl of the Minaduki household. Her somewhat active and perverted imagination causes her to interpret various everyday occurrences in a sexual manner and become aroused as a result. Her breed is the Scottish Fold.

Cinnamon is typically polite, soft-spoken and very cheerful. However, her mind has been shown on several occasions to be actively dirty to the point where something as mundane as attempting to explain how plants reproduce to Vanilla ends up with her likening it to sex and becoming aroused. She seems rather shameless about this trait as she will do it in public or in front of customers while working at La Soleil.
