Dual and Dorothy, faithful computer antivirus programs, monitor and constantly scan for corruptions in the simulated worlds of the Box of Wisdom. Whenever a virus is detected, it—and in many cases the entire world as well—is forcibly purged. This routine occurs every day without change, until the deletion of a particularly large virus cluster reveals an unknown program—calling herself Remo—with no memory of her function. She offers a fresh perspective into the monotony of Dual and Dorothy's lives as her influence causes the two programs to realize that there is more to life than just their mission. No longer spending their time only watching over the worlds, the three girls start truly experiencing them. As they explore digitally recreated cities and landscapes, Dual and Dorothy develop a special appreciation for what they have, all while searching for clues regarding Remo's forgotten purpose.

School clubs usually advertise their activities, but the goings-on of the GJ Club are a mystery. Kyouya Kyoro Shinomiya recently joined and became the sole male member of the five-person club. Besides Kyoro, there is Mao Amatsuka, the club president who has a tendency to bite Kyoro when she gets mad or bashful; Megumi Amatsuka, Mao's composed younger sister who always makes tea and desserts for the club's members; Shion Sumeragi, a demure chess prodigy; and Kirara Bernstein, a meat lover with a strong feline personality. All four girls have some form of interest in Kyoro. With the girls' idiosyncratic and cute personalities, Kyoro's time in GJ-bu will never be a dull one, for better or for worse.
