Yuyushiki

Yuyushiki (ゆゆ式, lit. "The YuYu Style") is a Japanese 4-panel manga series written and illustrated by Komata Mikami, which began serialization in Houbunsha's Manga Time Kirara magazine from April 2008. A television anime adaptation by Kinema Citrus aired in Japan between April and June 2013.

Plot
The series follows the daily lives of three high school girls; the intelligent but childish Yuzuko, the kind but airheaded Yukari, and the mature and easily irritated Yui, who are all part of their school's Data Processing Club. As the girls spend their days having meaningless discussions, they occasionally come up with themes to research while in the clubroom.
