The granddaughter of the Rabbit House's owner. A soft-spoken girl who slowly warms up to Cocoa, though is often annoyed by her insistence on being called "big sister." Along with her father, she is the only one who knows the secret concerning Tippy and her grandfather. Chino acts far more maturely than her age, and is normally the most responsible and organized member of the Rabbit House Café. She has a reserved and emotionless disposition, rarely smiling even when happy, and she speaks in a flat monotone voice with polite grammar. She takes her work very seriously and gets annoyed when people act recklessly or loudly around her. Chino resents the way she is often treated like a child due to being the youngest and shortest of the group. She gradually develops a strong bond with Cocoa, sometimes reminiscent of her own sister complex. When not companied by her, she often misses her and shows envy when she’s around others.
"She doesn't need a photo of me smiling now. I am to Cocoa a lion who pushes its cub off a cliff. Only when she climbs back up will I allow her to photograph me smiling. Probably."
