Joshikousei no Mudazukai

One day out of boredom, Tanaka decided to give her classmates nicknames based on their quirks. Her friend Kikuchi became "Ota" for her nerdy interests, and her other friend Saginomiya became "Robo" because of her expressionless personality. In retaliation, her friends decided to name Tanaka "Baka". These are the ridiculous days of three high school friends claiming (or not) the height of their youth.
