What is "yuyushiki"

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. The story follows a group of three girls who join their high school's Data Processing Club. As the story unfolds it becomes readily apparent that the trio's methods of "processing data" are quite loose indeed, often to humorous effect.
