Rosie has a 'rosie strawberry' shoulder-length bob along with pink coloured contacts for her eyes. Her skin colour is a pale white, but is not the lightest tone within the game.
She is a very kind and down to earth girl.
When the player first meets her, she comes across as very clumsy as she trips over the player's feet.
Rosie has just moved to the city from the countryside and was brought up by a family of farmers. Therefore, she is used to being with animals. Moreover, she is also very hardworking and ambitious as she wishes to become a pop star the moment she enters the new city.
- Rosie's Japanese name is Sakurako Yayoi (桜野やよい).
- She has a brother and a sister, and also thinks of her family's cows, Big Moo and Mini Moo, as her siblings.
