あそびあそばせ - 日本生まれ日本育ちでまったく英語ができない金髪の美少女・オリヴィア、真面目で知的な雰囲気を漂わせながら英語がまったくできないショートカットの眼鏡っ娘・香純、そして明るいけれど、リア充になれないおさげ髪の少女・華子、3人の女子中学生が作ったのは「遊び人研究会」!?
Asobi Asobase - During recess, Olivia, a foreign transfer student who doesn't know English, plays a game of "look-the-other-way" with Hanako Honda, a loud-mouthed airhead. Their rowdy behavior spurs the ire of Kasumi Nomura, a deadpan loner constantly teased by her older sister for her tendency to lose games. Not willing to compete, Kasumi declines Olivia's offer to join the fun, but eventually gets involved anyway and dispenses her own brand of mischief. Soon, a strange friendship blossoms between the peculiar trio, and they decide to form the "Pastime Club," where they are free to resume their daily hijinks.
Whether it be failing to learn English, trying desperately to become popular, or getting caught by teachers at the wrong time, school life will never be boring when the girls of Asobi Asobase are up to their hilarious antics.
