Toyo

Toyo stands at an ordinary height with an average frame and a bald head, and he tends to keep his eyes closed. He wears a muted yellow-and-black striped kimono with light trousers and dark footwear. When he first appears, he is shown smoking a kiseru pipe.

Toyo takes deep pride in his udon. He is openly annoyed when Tanjiro abandons a bowl without tasting it. Once the boy comes back, orders two more servings, and devours them, Toyo softens, pleased and grateful for the business.

Born and raised in Asakusa, Toyo grew so fond of the city that he set up an udon cart at its edge to stay there. In the Asakusa arc, during Tanjiro's second assignment investigating a demonic presence, the overwhelmed slayer flees the crowded streets and stops at Toyo's stall. As he prepares to eat, he detects the scent linked to the slaughter of his family and bolts after it, knocking his bowl to the ground.

When Tanjiro returns, Toyo scolds him for the wasted meal, so the boy buys another bowl, then a second when Toyo presses Nezuko to eat as well. Toyo watches in astonishment as Tanjiro finishes both portions almost instantly, then waves the siblings off warmly as they leave, thanking them for their patronage (Episode 7).
