He became the Roaring Pillar by succeeding the former Roaring Pillar, Jigoro Kuwajima (the master of both Kaigaku and Zenitsu). He can perfectly execute Thunder Breathing from the First Form to the Sixth Form. He only shows proper manners toward Kagaya Ubuyashiki, the leader of the Demon Slayer Corps.
