Sumika Murasame is not a cute girl. Her peers nickname her "Violence Murasame," and her tall, imposing figure shows little sign of femininity. Unfortunately for Sumika, her best friend and crush, Ushio Kazama, is only attracted to cute girls. Ushio loves to gush about her endless crushes, remaining completely oblivious to Sumika's feelings. During their first year of high school, Sumika and Ushio meet Tomoe Hachisuka and Miyako Tamae, two other girls with a similar orientation. Wanting to start a club for "girl-loving girls," the group tries to find a fifth member and get their club approved. Although Sumika has some reservations about the club's purpose, she sees this as an opportunity to get closer to Ushio and resolve her unrequited love.
