Zenitsu Agatsuma

Zenitsu is a fair-skinned teenager with short hair, formerly black, but after an accident during training when he was struck by lightning, his hair became bleached blonde with some orange streaks. His eyes are a golden brown and his eyebrows are thick. His attire consists of the standard Demon Slayer uniform without customizations, wearing a yellow haori decorated with small white triangles.

During the events on Mount Natagumo, Zenitsu was poisoned by demon spiders, causing his limbs to shrink, although after a brief recovery period, they returned to normal.

By nature, Zenitsu is cowardly. He always claims he doesn't have much time left to live due to the dangerous job of being a Demon Slayer. He's also somewhat of a womanizer and likes to flirt with girls he thinks are pretty, asking them to marry him much to their annoyance.

Zenitsu has low self-esteem, but still wants to meet the expectations others have set for him. However, he was constantly afraid and always cried and ran away. He claims he wants to live a modest life where he can be useful to someone.

Despite his lack of self-esteem, Zenitsu has great respect and admiration for his comrades and his deceased master, Jigoro Kuwajima. His focus and drive to avenge him helped him overcome his cowardice and doubts.

Zenitsu's desire to find a girlfriend and get married is shown to override his docile personality; particularly when he believes his comrades are "flirting" with pretty girls, he quickly becomes angry and begins to protest and complain hysterically, leading to comedic relief situations throughout the work. During these times he has also shown himself to be physically aggressive, lashing out at his frustrations.
