Yatsu

Yatsu (やっ) is a minor character of Demon Slayer: Kimetsu no Yaiba. He is a civilian that Muzan Kibutsuji bumped into at an alleyway in Asakusa.

Appearance
Yatsu is a short man with an average posture. He has a big forehead and shoulder-length black straight hair. During his appearance, he wore a yellow vertically striped haori over a light green kimono and a dark green hakama. As he was drunk, his face was flushed with significant red spots on his forehead and cheeks.

Personality
Yatsu is a stubborn, pushy and aggressive person who displays unruly behavior. Even when he is the one at fault, for instance when he drunkenly bumps into a stranger, he blames the other individual and isn't satisfied with an apology. He tries to assert dominance over his victim through physical intimidation, by grabbing the victim's shoulders to stop him from leaving the scene, and through verbal intimidation by mocking the victim's clothes and physical appearance. It doesn't seem like he cares that the victim is physically taller than himself. As his older brother is much taller and bigger than most people, he may be more daring to display his antagonizing behavior since his nearby brother will always be protecting him in case it gets physical.

He seems to bear disdain for people from higher classes, as evident by his comments on the quality of Muzan's clothes.

He loves drinking, as evident by his suggestion for more rounds at bars. Even with a flushed face and poor coordination, he tries to fool himself and his companions into claiming he is not intoxicated.

Asakusa Arc
In Asakusa, Yatsu had been drinking at bars with his older brother and a woman. They are very drunk when they walk through an alleyway. While dancing around, he suggests to his brother to hit up one more bar. When the woman asks him if he is alright, he says he is fine and not even drunken yet.

As he wasn't walking in a straight line, he bumps into a man by accident. Yatsu gets angry and yells at him. The man quietly apologizes and proceeds to walk past him. However, this doesn't satisfy Yatsu, who grabs the man's shoulder and yells at him to come back. He says again that he is in a hurry but this only annoys Yatsu even more, who then begins to point out his expensive looking clothes. He then walks in front to see the man's face and laughs at his pale skin and claims he looks close to dying.

This last comment deeply enrages the man, but Yatsu doesn't notice and continues taunting him for not responding to his ridicule. The stranger suddenly raises a fist and brutally punches the drunkard into the wall, breaking his skull. The woman immediately runs over towards him and announces to Yatsu's older brother that he is not breathing.

Abilities
As an ordinary human, Yatsu does not possess any additional power or abilities.
