Karaku is a tall and muscular young man with shoulder-length hair and narrow, deep green eyes with the daiji of "Upper Rank Four” engraved into them. He has two prominent curved horns on his forehead and cracked markings under his eyes. Karaku also has the kanji for "pleasure" etched into his tongue. He has pointed ears and sharp nails on each finger. He wears nothing but hakama pants, a pair of zori, and two sashes on both shoulders. Karaku is always carrying around a fatsia leaf-shaped uchiwa.
