Atsushi Miyagawa

Despite being a fifth-grade elementary student, this protagonist possesses an unusually mature appearance and a towering 180cm stature. Because of his strikingly grown-up look, he frequently finds himself misidentified as a teacher or a parent by those around him. However, beneath this imposing physical presence, he maintains the heart and behavior of a typical young child, navigating his daily life with the genuine personality of a fifth grader.
