──Do you think you'd believe it? Our story, a tale that's mysterious, beloved, poignant, and precious, one that can't just be told as "fun"── Turkey... A bowling term for getting three consecutive strikes. Mai, a second-year high school student and the captain of the Ikkokukan High School bowling club, is a genius who can't win. Whenever she gets a Turkey, for some reason, she invariably ends up with the impregnable split, a Snake Eyes, right after. To Mai, Rina, the only first-year club member, said, "You're doing it on purpose, aren't you?" "Captain, you're running away from winning. I want to win. If you're not serious about winning, I'm quitting the club."── This is the story of Mai, Rina, Sayuri, Nozomi, and Nanase... The five members of the Ikkokukan High School bowling club, who fought through losses, again and again, and eventually achieved victory. It's a story from the end of summer.
