After her parents died in a car accident, Ori, a sixth-grade elementary school student, was adopted by her grandmother who ran the hot spring hotel "Haru no Ya". She also began her journey of training as a little girl general. She was naive and reckless, and was often ridiculed by Akino Mayuki, a girl of the same age from the rival hotel. But Ori, who was optimistic by nature, tried her best to entertain every guest with the encouragement of the ghosts of the hotel, Xiaomai, Miyang and Suzuki. This is a warm and joyful story of a girl's growth.
