Rose

Appearance
Rose has pale pink skin and messy orange hair tied into a braid. Her eyes are pink-red. She wears a light pink gown with loose sleeves. She has a white cat tail with a pink ribbon wrapped around it connected to a small bell.

Ending 2
Mentioned at the start of the game as an unseen narrator is telling her to dream a happy dream of a world without stress, Rose can be seen at the beginning of Ending 2 when she wakes up from her nightmare before falling back to sleep. Then it returns back to Sissy at the camp with the other characters.

While it is implied that the events taking place in the town and forest are all a product of Rose's dreams, Dream of Gluttony does not expand upon her role in the universe. This may eventually be explored further in later games from the dev.
