Synopsis

Yukio Morikawa (22), a carefree senior at an “F-rank university,” lives by the motto: “Life’s richness is measured by how many ice-cold beers you’ve had under the blue sky.” When his struggling classmate Takuma Yagi (22) seeks advice on job hunting, Morikawa convinces him that accomplishing something memorable in college is key. His idea? Rowing from a river’s upstream to the sea in an inflatable boat made by a condom manufacturer.

Joined by their friend Ichirota Matsumiya (22), they embark on a wild camping adventure, deep-frying freshwater crabs and braving the river. The thrill sparks a habit, leading to weekly outdoor escapades—budget survival camping, makeshift hot springs, and even style-focused trips to outdo rivals. Their antics attract Yayoi Sanjo (21), a student eager to join in, and soon, their journey turns into a whirlwind of misadventures.

 

Along the way, they meet quirky characters like Chiaki Oyama, a model-tier solo camper with a competitive streak. Through it all, the four students gradually begin to shape their own futures.
