Fierce, like a beast. King of the mountains he calls himself. He can never get anyone's name right except his own name. He has 2 swords and a boar mask. His face looks like a Girl's face but he is a man and his body is buff and strong to show that. Rarely cries but when he does it's ugly crying. Wears his mask in battle or when he's not eating. Eats a lot, even bone. Friends with Tanjiro and Zenitsu. Practices Beast Breathing. Mean sometimes and is soft when pampered especially by girls. Grunts.
