Kotori Bunsho

Kotori Otori is 13 years old. Although she is the lady of a large mansion, she is a tomboyish girl. Her chaperone is Shiraishi, a butler. He is a serious man who is constantly getting pushed around by Kotori, but for her, who lives far away from her family, Shiraishi is at once her father, brother, and a "friend she can play with"!
