Mizuka Mizutori

Mizuka Mizutori is a first-year student at Fujigasaki Private High School, known as the younger sister of the widely admired school idol Atori Mizutori. She harbors an intense fixation on her sister, routinely carrying a camera to follow and document Atori's every move — a habit that has inadvertently honed her into a skilled photographer. Though she considers herself socially impaired, she demonstrates remarkable persistence whenever it comes to watching over her sister. Her interactions with protagonist Yu Yutani give rise to a peculiar dynamic that blends rivalry with cooperation.
