Yui Ichii, Yuzuko Nonohara, and Yukari Hinata make up an unusual trio of friends; despite each girl being eccentric in her own way, they get along well. Now starting high school, the friends look forward to the coming years together while also desiring to be part of something larger. Upon discovering the data processing club, which has no members and faces disbandment, they immediately decide to join. As the club's newest members, Yui, Yuzuko, and Yukari spend their time engaging in wordplay, teasing one another, and using computers to search for topics for amusing conversations. The girls' daily lives never become dull as they enjoy their time at school to the fullest.
