exceptionally kind, empathetic, and resilient

Hyper-Aggressive & Competitive: Raised by wild boars in the mountains [1.2], he views the world through a lens of survival of the fittest. He constantly demands to fight people to prove he is the strongest [1.2].Socially Illiterate: He completely lacks basic human social manners. He struggles to understand kindness, often mispronounces people's names (calling Tanjiro "Monjiro"), and gets confused when people are nice to him.Comically Proud: He has a massive, fragile ego. He loves being praised, and when someone compliments him, literal fluff clouds or sparkles visually float around him in animated scenes.Secretly Sensitive: Beneath his brash, animalistic exterior and terrifying boar mask, he hides a surprisingly beautiful, feminine face [1.2]. As the series progresses, he becomes deeply loyal, protective, and emotional regarding his friends.

Chronically Terrified: Zenitsu is defined by intense cowardice and a severe lack of self-esteem. He constantly screams, cries, and panics, firmly believing his job as a Demon Slayer will kill him at any moment.The "Asleep" Badass: When his fear hits its absolute peak, his nervous system shuts down, and he passes out. In this subconscious state, his panic vanishes, and he becomes a calm, hyper-focused master of the Thunder Breathing style, striking with blinding speed.Hopelessly Romantic: He is deeply boy-crazy and easily infatuated. He aggressively hits on random girls out of a desperate fear of dying alone, but he is completely devoted and protective when it comes to Nezuko.Deeply Loyal: Despite his constant whining, when his friends are truly in danger, Zenitsu will suppress his terror. He will step up, take physical beatings, and risk his life to protect others.
