Zureta Kaishaku no Bokura

Meguri Omoi is a beautiful and upright student council president. While she cannot tolerate any disruption to school discipline, she is secretly an otaku of the slightly risqué romantic comedy "Miracle☆Campus" (commonly known as "Mira☆Can")...! One day, Meguri encounters transfer student Kou Fukanose, and a sudden clash of interpretations regarding their beloved "Mira☆Can" erupts...!? An otaku with a secret she can't tell anyone, and a transfer student who knows more about "Mira☆Can" than anyone else—a new kind of mismatched comedy begins here!
