Yuzuko, Yui, and Yukari, three girls who just started high school in spring, are always together. After school, the three of them attend their own "Data Processing Club" with two computers and a whiteboard between them, searching for random words on Google and then discussing the results. Their day to day life is mostly uneventful, mainly only consisting of girls flirting, but for some reason it's difficult to tear one's eyes away from this new generation of high school girls' communication. Their cute, laid-back high school lives are defined by hanging out, club activities, and occasional hints of yuri. Au uneventful, good life - that is their "yuyushiki" (rule).
