IS ~Otoko Demo Onna Demo Nai Sei

IS follows the high school life of Hoshino Haru. Haru was born intersex meaning that he was born with physical characteristics of both sexes and cannot clearly be assigned to either common gender based on those physical characteristics. Registered as female at birth but later raised as a boy since he always played with boys his age and boys toys. Haru is forced to attend high school as a girl because of that original registration.
