Japan circa 1920. Okoma Tsumagoi is a roving, independent yakuza who gambles for a living. At the beginning of the story, she settles scores with another yakuza, showing off her skills with both a pistol and a sword. Along the way, she meets Tsukuba, another gambler. He has his 8-year-old daughter Onatsu in tow since her mother has already died. Okoma takes care of Onatsu when she suddenly falls ill. She remembers her own story. Okoma grew up as an orphan at the Yakuza and is still looking for her own mother.
Okoma takes little Onatsu to her grandparents at her father's request. They live in Kakei, a bathing resort with hot springs. This is where the whole tragedy of events unfolds, because the dishonorable Yakuza Ishiwari wants to take control of the bathing resort with its three hostels.
