Haruo Yoshikawa

This average junior high student maintains a perfect school attendance record while navigating a life where he remains completely unaware of his family's hidden magical abilities. Living with his three sisters, he is kept in the dark about their powers, including the use of memory-erasing hammers, which some of them employ. Despite his naivety about the world and others' emotions, he possesses a deep sense of care for the well-being of those around him. He is currently a first-year student in classroom B.
