Yuyushiki (Japanese: ゆゆ式) 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 issue. An anime television adaptation by Kinema Citrus aired in Japan between April and June 2013. An original video animation was released on February 22, 2017. The series' name is derived from the term "yuyushiki jitai" (由々しき事態, lit. "in a serious situation").
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 (情報処理部 Jōhōshori-bu). As the girls spend their days having meaningless discussions, they occasionally come up with themes to research while in the clubroom.
- Yuzuko Nonohara (野々原 ゆずこ Nonohara Yuzuko)
- Voiced by: Rumi Ōkubo
- The first member of the Data Processing Club. She normally has an innocent nature, but will sometimes break out into bouts of outrageous behaviour. Despite her dimwitted behaviour and crazy ideas, she is actually quite smart when it comes to studies.
- Yui Ichii (櫟井 唯 Ichii Yui)
- Voiced by: Minami Tsuda
- The second member of the Data Processing Club. A generally serious girl who often serves as the straight man to the antics of Yuzuko and Yukari, who often like to tease her.
- Yukari Hinata (日向 縁 Hinata Yukari)
- Voiced by: Risa Taneda
- The third member of the Data Processing Club. A generally light headed girl who will often copy Yuzuko's antics if she finds them amusing. She comes from a rich family and was friends with Yui in elementary school.
- Chiho Aikawa (相川 千穂 Aikawa Chiho)
- Voiced by: Ai Kayano
- A classmate of the girls and the class president. She is a quiet girl who admires Yui a lot and wants to become friends with her, but is usually intimidated by Yuzuko and Yukari's antics.
- Kei Okano (岡野 佳 Okano Kei)
- Voiced by: Megumi Han
- A classmate of the girls and Chiho's friend. She is quite fond of Chiho and is often cold towards Yui for allegedly taking Chiho away from her.
- Fumi Hasegawa (長谷川 ふみ Hasegawa Fumi)
- Voiced by: Mana Shimizu
- A classmate of the girls and Chiho and Kei's friend. She is aware of Kei's fondness for Chiho and often teases her about it.
- Yoriko Matsumoto (松本 頼子 Matsumoto Yoriko)
- Voiced by: Yui Horie
- The girls' homeroom teacher and advisor of the Data Processing Club. She is often called "Mom" (お母さん Okā-san) by her students due to her generally kind nature.
