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.

Tanaka Nozomu is one of the three high school students. People call her "Baka" ("Idiot"). She isn't timid and she can't read between the lines. Her friends are Kikuchi Akane and Saginomiya Shiori . Akane enjoys anime and manga. Shiori is extremely smart, but her emotions have dried up. These three girls are also classmates. Their homeroom teacher is Sawatari Masataka.
