Zenitsu Agatsuma

Zenitsu Agatsuma is one of the main supporting characters in Demon Slayer: Kimetsu no Yaiba.

He's a young Demon Slayer Corps member who wears the standard uniform with a distinctive yellow-and-orange checkered haori. Physically, he has bright yellow hair with a distinctive lightning-bolt-like fringe and large, scared-looking eyes.

Personality-wise, Zenitsu is most famous for being:

• Extremely cowardly and anxious
• Constantly crying, complaining, or panicking
• Terrified of demons, pain, and basically everything
• Obsessed with girls (especially pretty ones) and frequently tries to flirt or propose marriage on the spot

Despite this behavior, Zenitsu is actually very powerful when unconscious — he becomes an incredibly skilled and fearless fighter, using his Thunder Breathing style with exceptional speed and precision. His unconscious combat form is so strong that it's often said his true potential only appears when he's knocked out or asleep.

In short: a hilariously terrified crybaby who turns into a badass lightning-fast swordsman whenever he passes out.
