Rinkai!

The manga follows Ami Kurata, a first year college student with no special qualities. One day she happens to notice someone riding a folding bike, immediately falls in love with it, and uses all her savings to buy one. She eventually gets introduced to the world of long-distance bicycling and road racer bikes, and she forms a cycling team called Fortuna with four other female college students from the same school. Their goal is to ride in a "brevet" or long-distance event called "Fresh."

Rin Namiki's greatest ambition is to follow in her late mother's footsteps and compete in Kandagawa Jet Racing, where teams of girls on jet skis race while firing high-powered water guns to slow their competitors' jets (and blow off their clothing!). But since there's no jet racing in Rin's remote fishing village, that means moving, all by herself, to a girls' school in faraway Tokyo! Meanwhile, Misa Aoi dreamed of becoming a great player, but those ambitions floundered until Rin transferred to her school, displaying astonishing skill for a newcomer. Is it fate? Now they "only" have to resurrect their school's Jet Riding Club, endure brutal training, and face some seriously skilled rivals… but even the toughest tasks are easier when you're doing something you love with someone who's quickly becoming far more than just a friend!

The story centers around girls who compete in sport climbing, particularly climbing artificially constructed walls. First-year high school student Konomi Kasahara discovered this sport at Hanamiya Girls' High School after training her mind with puzzle games during junior high school.

A high-school girl, Etsuko, just spends her days without any aims or purpose, until one day, Riina, a transfer student, asks her help to set up a boat club. Although Etsuko reluctantly accepts after hearing Riina speak passionately about her dream, she gradually starts to embrace the club after spending time with her teammates.
