—Masato Hiyami, Corpse Party 2: Dead Patient
Masato is a teenage boy of below average build and below average height. He has dark blue hair and light blue eyes. He possibly wears Tsukinoka High School's uniform.
Born with a weak body, Masato was forced to change schools repeatedly due to his illness and frequent hospital visits. Originally a cheerful, upbeat, never-say-die type of youth who was well liked by his peers. His transfer to a middle-of-nowhere land with no community to speak of has affected his maturation to adulthood. Masato attended his third year in elementary school in the same class as Ayame Ito and Chiyomi Homura where they got along well.
