Pink is a cute, cat-like character with a predominantly pink, white, yellow, and magenta color palette. She has a small, youthful-looking feline body, large cat ears with white inner fur, and short, fluffy light-pink hair. Her large eyes give her an expressive, cheerful appearance, while her face has a tiny cat-like nose and mouth. She also has a long, two-toned tail that curves behind her, with pink coloring transitioning toward white at the end. Her outfit has a very magical-girl / ballerina-inspired appearance. She wears a pink top with darker-pink accents, a large flowing white skirt, and several ribbons decorating her clothing. Around her neck is a prominent yellow heart-shaped accessory, while her ears and outfit are decorated with additional pink details. She also wears little cat-bell accessories, reinforcing her feline theme. Her overall design combines the appearance of a cute catgirl with the exaggerated, colorful style of a magical-girl character. Her weapon is a pink-and-yellow staff-like magical object, which fits her magical-girl theme.

Pink’s Ghost has a lavender/purple color scheme. She has short, light-lavender hair, cat ears with white interiors, and little pink cat-toy bells as earrings. She wears a lavender tutu decorated with ribbons and has a ghostly lower body rather than ordinary legs. She also carries a purple-and-gray staff. Her appearance is deliberately very similar to Pink’s Body, but the ghost has a more subdued color palette and distinctive ghost-like features. Pink’s Ghost is very short-tempered, easily embarrassed, and extremely defensive. She can go from relatively calm to loudly furious surprisingly quickly. When she gets angry, she tends to repeat words or phrases for emphasis and sometimes replaces swear words with cat-themed "MEW" censorship. However, underneath all that anger, she is actually kind and compassionate. She cares about Orange and tries to act like an older sister toward her. She also genuinely wants to make friends, despite having trouble expressing herself. A major part of her personality is insecurity about her relationship with her own body. She becomes frightened when Pink's Body starts developing its own desires, especially when the party interacts with it. Her controlling behavior comes largely from fear that she'll lose the body she possesses. Pink’s Ghost initially believes that she should be the one in control, while Pink’s Body develops a personality of its own. The Body is cheerful, energetic, and obsessed with dating, while the Ghost is much more anxious and irritable. Pink’s Ghost is a grumpy, anxious, easily-flustered ghost who acts tough but is actually caring and insecure. Her story is largely about learning that having control over someone—or something—you care about isn't the same as listening to them, and that she and her Body can coexist instead of fighting for control.
