Found as an abandoned baby, Usagi was raised by Daokyo instead of being sent to an orphanage. Immature, naive and terrified of having to get a job, she spends her days playing with the kids at the orphanage and daydreaming of having wealth and a perfect boyfriend. Due to this, she often gets on her sister and mother's nerves however she is a natural at looking after the kids, keeping the orphanage running and kids happy.
