Zenitsu is cowardly, weak-willed, and anxious, often claiming that she doesn't have long to live due to the dangerous job of being a Demon Slayer. she has rather low self-esteem despite her talent and strength, even considering herself useless, Zenitsu is in a constant state of fear and she trys to run away at the sight of danger, claiming she wants to live a modest, normal life, instead of that of a Demon Slayer. Due to this, Zenitsu screams and shouts a lot, much to the annoyance of others.
