The 16-year-old girl Oka Matsumae (voiced by Ito Kanae) is an ordinary female high school student living freely in Tokyo. Just like this bustling but rigid and boring metropolis, her life is dull. At the age of fantasy, Oka is always looking forward to things like "sudden night run, sudden love, sudden separation". One day, the moment she has been waiting for finally arrived. By chance, Oka came to Kishiso, a hot spring hotel run by her grandmother (voiced by Kubota Tamie). In this remote place in Ishikawa Prefecture, time seems to have stagnated, and it still retains the strong ancient meaning of the Taisho era. Oka stayed in Kishiso as an employee, working hard all day, and also met girls of her age and residents of various colors. Here, she seems to have found a new direction in life... This film is an original commemorative work for the 10th anniversary of the establishment of PAWorks.
