Karaku

As the manifestation of Hantengu's pleasure, Karaku showcased himself to be the most relaxed and laid-back of Hantengu's clones. The entire time he was battling against Genya, Tanjiro and Nezuko, he was constantly praising them and, instead of taking the battle seriously, he saw it as nothing more than a game, seeming to only take interest in the new experiences he was obtaining in the battle. This was demonstrated during his battle with Nezuko, when, instead of finishing her off immediately. Karaku was one of the most outwardly sadistic clones, gleefully smiling whenever he got the upper hand or inflicted pain onto his opponents. In addition, after he and Sekido are beheaded by Genya, he cracks a wicked grin knowing that the Demon Slayer had inadvertently freed Aizetsu and Urogi. He also seems to display masochistic tendencies, evident when he happily expressed his interest in the new sensation of having his neck being severed by a gunshot from Genya, commenting that he had never been injured like that before. Despite this, he could lose his patience should his opponent prove too challenging to finish off, as seen when he gets angered at Tanjiro slashing his arm even when knocked to the floor. He notably did not enjoy being decapitated by Tanjiro using Sun Halo Dragon Head Dance with a blade enhanced by Nezuko's explosive blood, as he wailed in agony from the pain.

Appearance: Karaku is a tall, lean young man with deep green eyes inscribed with kanji and daiji. He has long, spiky hair tinged green and two curved horns on his forehead. Karaku's tongue bears the kanji for "pleasure." He wears green hakama pants and carries a fatsia leaf-shaped Uchiwa fan.
