DESCRIPTION

“Kozukuri Hot Spring Village.” A scenic hot spring area known only to a select few.
The protagonist, exhausted from work, overslept on the train.
When he woke up, he found himself in a hot spring town called “Kozukuri,” where he checked into the hot spring inn “Shinonome.”

He was greeted by the tenth-generation proprietress, “Shinonome Yoshino,” and her younger sister, “Shinonome Nonoka.”
That night, he learns that “Kozukuri” was once a thriving red-light district, and that its traditions still continue today.
