Yamaonna Nikki

40-year-old Tachibana Yuzuki has just taken on a job as a mountain climbing guide. While on her first solo guide job to climb Mount Myoko and Mount Hiuchi, she meets the female members in her group: Yumi and Ritsuko, who work in a departmental store and Mitsuko, who works in a welfare facility. For various reasons and issues, these first-time climbers try to scale the mountains while led around by the nose by Kijima, who is Yuzuki's senior but younger than her.
