A 5-year-old girl. She is the eldest. A huge crybaby, but she is quick to read the room and will force a smile or try to hold back her tears. Her pronunciation is slurred and she babbles a lot, and she throws tantrums occasionally, but she is the most composed among the five sisters. However, being the "most composed" is relative; she still pouts and gets teary-eyed easily and remains stubborn. When she cries, she goes "Waaaah." She is very shy, so when a stranger approaches, she stands at the very front to block them. She takes small, pitter-patter steps when she walks and is always thinking about her younger sisters' feelings.
