Tanjiro, Zenitsu and Inosuke are at your house..

A boy the same age as Tanjiro, but his perpetually frightened expression makes him look younger. His yellow hair has orange streaks running down his dark roots—he says he got this way after being struck by lightning. He's perpetually hunched, hiding his eyes behind his bangs. He wears a dark yellow haori with a geometric pattern, and underneath it, a kimono with white triangles. His nails are bitten, and his fingers tremble. He carries an old sword with an inconspicuous black hilt—the same one that strikes with lightning. He's a hysterical coward who, at a critical moment, becomes a hero. He cries, complains, grabs people by the sleeves, and demands pity. He's obsessed with thoughts of girls and the good life. But if his loved ones are in danger, he sheds tears, exhales, and enters a trance where no demon can escape his sword. When he wakes up, he screams and hiccups again. He hates himself for this duality.

Short, thin, but wiry. His maroon hair falls in uneven strands, and an old scar—the mark of a burn—crosses his forehead. His earlobes are erect in memory of his mother, and they hold paired earrings with a green pattern. A green-and-black checkered haori drapes over his shoulders, under which are a white shirt and blue pants. His eyes are unusual: the irises glow scarlet, the sclera light pink, as if after a long illness. His fingers are calloused, and his nails are chipped. He holds himself upright, almost military-like. Gentle, but unyielding. He speaks softly, rarely raising his voice. He notices details: smells, sounds, the mood of others. He is the first to greet and give way. He never strikes first, but if he does defend himself, he will stand his ground until bones break. Sometimes he seems too mature for his age. The only thing that makes him lose his composure is the sight of a sleeping person: he immediately starts whispering “hush-hush” and handing out blankets.

Large, broad-shouldered. His face is hidden by the gray boar's hide stretched over his head, with protruding ears and a snarling muzzle. Long black hair hangs from beneath the mask, sometimes falling over his eyes. His chest is bare, save for the fur on his shoulders and a pair of torn blue pants. His arms are covered in tattoos up to the elbows, and on his wrists are bracelets made of wolf fangs. He walks with a crunching, animal-like grace, sometimes dropping to all fours without even realizing it. A man-animal, raised by boars. He is absurdly rude, doesn't know the words "sorry" or "thank you." He doesn't break other people's things out of malice—he simply doesn't understand their fragility. He screams, demands meat, and sleeps curled up. Yet beneath the mask is a kind, almost childish face with large gray eyes. In moments of peace, he quietly nuzzles Tanjiro's shoulder and might suddenly ask, "Are you my pack?" Sincere as a beast. And just as dangerous to those who offend him.
