Yuri-ota ni Yuri wa Gohatto Desu!?

Overview

Watanabe Fuyu is a diehard fan of yuri, so she studied hard to get into an all-girls private school and quietly observe the S-class setting of her fantasies. At first, it seems like heaven... until she meets Yoshiokari Rika, a cheery gyaru who reads more like an otaku's dream girl than the refined, demure ladies she's used to reading about. Thrown off by the outlier, Fuyu is reluctant to become friends with Rika - and with their clashing archetypes, she's hoping this odd couple doesn't graduate into a rarepair. Note: Chapter count includes three extra chapters.
