Hatsuka is a man of small stature with an androgynous physique, having a rather masculine, but very thin, upper body and feminine hips, his head adorned with shoulder-length black hair, and a narrow face. He prefers to dress femininely, which he says is apparently because it suits him better. The clothes he mainly wears are dresses and coats, his footwear consisting of dark calf length boots, smaller shoes and slippers when he is at home.
