Aokou Cheer-bu wa Kawaikunai!

Mai Maizumi, the beautiful but foul-mouthed cheerleading club president, aims to make the club cute and popular. She works hard to recruit new members (backup dancers), but the club members who gather include an unpopular girl who staked her life on debuting in high school with a new image, a baseball nut, and an anime otaku! All the overly-idiosyncratic club members are united by cheerleading! Fans of high school baseball and cheerleaders, gather 'round! (Source: Kadokawa, translated)
