Nadeshiko, a high school student who had moved from Shizuoka to Yamanashi, decides to see the famous, 1000 yen-bill-featured Mount Fuji. Even though she manages to bike all the way to Motosu, she's forced to turn back because of worsening weather. Unable to set her eyes on her goal, she faints partway to her destination. When she wakes up, it's night, in a place she's never been before, with no way of knowing how to get home. Nadeshiko is saved when she encounters Rin, a girl who is out camping by herself. This outdoorsy girls story begins with this first encounter between Nadeshiko and Rin.
Within the narrow walls of the Outdoor Activities Club room, the few but lively members carry on the camping spirit as they have fun with DIY club experiments. Exciting experiences such as these have brought Nadeshiko deep into the world of camping, making her want to once again go on a solo trip. However, other plans come first, as Ayano and Rin invite Nadeshiko to camp near Ooi River. Eager to go on their first journey together, the girls set off to forge precious memories that will stick with their hearts for years to come.
