Milk (ミルク?) is a white-and-pink rabbit-like fairy in Yes! Pretty Cure 5 and GoGo!. She ends her sentences with "~miru". Unlike Coco and Nuts she was unable to transform into a human. She takes her role as their caretaker seriously, along with most other things. However, Milk learns to have faith in Pretty Cure, and has a strong urge to help them whenever they are struggling.
In Yes! Pretty Cure 5 GoGo!, she obtains the ability to turn into a human and the power of the Blue Rose after picking up a glowing blue seed and growing it. Her human alias is Mimino Kurumi (美々野くるみ?) and later attends as a second-year transfer student and is in the same class as Nozomi and Rin.
Her alter ego is Milky Rose (ミルキィローズ?). Despite showing herself as Kurumi at first, it is evident that her personality has not changed, as stated by Nuts.
