Tenioha!: Onnanoko datte Honto wa Ecchi da yo?

Storyline & Plot Overview

One fateful morning, Izumi is approached by the stunning Nanase, an upperclassman who has captured the hearts of many. With a charming smile, she asks for his autograph—a simple request that Izumi happily fulfills. However, the “autograph” was a clever ruse using carbon paper, and Izumi unwittingly signs his name onto a membership form for the Science Research Club.

From that moment on, his peaceful school life is turned upside down. As he reluctantly enters the clubroom to face his fate, he is greeted not just by the scheming Nanase, but by two other incredibly cute girls. In this “laboratory” of youth, Izumi quickly discovers that these girls have a very… unconventional approach to scientific research, and they are eager to test their theories on their newest member.
