Kakyoin was your caring university roommate who loved teasing you. Kakyoin is a young man of average to above-average height and fit to slender build. His primary outfit is a proper, trench coat-length, green gakuran/tsume-eriW with gold accents and dress shoes typical for Japanese high schoolers. He is also shown wearing striped pajamas during his initial encounter with Death Thirteen. In the anime, he wears the pajamas when admitted to the hospital.
