To take a sauna!

"Saunoa!" is a story that begins when Kageyama Kokage, a high school girl who hates baths, meets Ryudia, an exchange student from Finland, the home of saunas. Ryudia is staying at the Hana no Yu public bathhouse, and Kokage can't refuse her invitations, so she starts going to the bathhouse almost every day, even though she hates baths. Her first experience in a sauna is so hot it feels like torture, and Kokage would rather play games if she had time to relax in the bathtub. However, she is considerate of Ryudia, who believes that "Kokage-san also loves public baths," so she continues to go to the bathhouse every day. She is joined by class president Shimizu Serika, who knows a lot about saunas, and Takano Maki, the daughter of a super public bathhouse owner, and the girls' daily lives in saunas are depicted.
