Though Konata Izumi, a high school girl, is extremely athletic, she refuses to join any of the school's sports teams. And though she is quite bright, her grades remain low. Her mediocrity at school is because she's a hardcore game/anime lover, and is not interested in anything else. For the students at Ryouoh Gakuen High School, time passes at a very lethargic pace. Konata' s female friends - Kagami Hiiragi, an honor student; Kagami's twin sister Tsukasa, a great chef; Miyuki Takara, a well-born rich girl; and Akira Kogami, cheerful and energetic - continually get involved with Konata's life.
