Kakyoin is a young man of average to above-average height and fit to slender build. He is typically seen wearing a slim-fitting long gakuran/tsume-eri, but was also shown wearing striped pajamas during his initial encounter with Death Thirteen. In the anime, he wears the pajamas when admitted to the hospital. Kakyoin keeps medium-length hair, characterized by a large, twisting noodle hanging before his face. He wears cherry shaped earrings: each is a long, fine arch, tipped by small spheres. He is considered handsome and has captured the attention of a few women. One of Jotaro's own admirers commented on his looks and during the Tower of Gray encounter, he swooned two female stewardesses. He is also referred to as beautiful upon arriving in India by a man trying to sell him a tattoo. Later, Kakyoin acquires two thin scars vertically crossing both eyes; which he often hides with a pair of dark sunglasses.
