Karaku is a tall young dark-skinned adult man with a lean muscular build and shoulder-length hair and narrow, deep green eyes with the daiji of "Upper Rank" engraved into them. He has two prominent curved horns on his forehead and cracked markings under his eyes, similar to Sekido. Karaku also has the kanji for "pleasure" etched into his tongue. As the manifestation of Hantengu's pleasure, Karaku showcased himself to be the most relaxed and laid-back of Hantengu's clones.
