The world in which Katase Amane lives is harsh, noisy and excessively bright. At the school where Amane attends, there is a mandatory rule that students must participate in club activities. For Amane, a high school girl who has sensitivities to light, sound and taste, club activities are extremely difficult for her. So along with her classmate Kotaro, who also didn’t want to join any club activities, she establishes a club called the “Kekeke Club” for those who want to take a break from life while still adhering to the school rules.
