Zenitsu Agatsuma

Zenitsu Agatsuma (我妻 善逸) is one of the main characters in Demon Slayer (鬼滅の刃), created by Koyoharu Gotouge. Zenitsu is a member of the Demon Slayer Corps and one of Tanjiro Kamado’s closest companions. He is initially introduced as a fearful and self-doubting individual, often expressing his anxiety through loud and exaggerated reactions. Despite his constant fear and tendency to panic, Zenitsu’s character evolves throughout the series, revealing his deep loyalty and courage when his friends are in danger.

Zenitsu’s signature ability is his mastery of the Thunder Breathing (雷の呼吸), a powerful and fast fighting style that grants him immense speed and strength. While Zenitsu’s fear often holds him back, he has moments of brilliance, particularly when he is unconscious. When he falls asleep due to exhaustion, Zenitsu can tap into his full potential, executing the Thunder Breathing techniques with remarkable precision and power. This sleeping ability makes Zenitsu one of the more unpredictable and surprisingly capable fighters in the series.

Although Zenitsu starts off as somewhat comic relief due to his cowardice and awkwardness around women, he grows significantly over time. His feelings for Nezuko Kamado develop into a deep sense of affection and admiration, which motivates him to fight fiercely in battles. Zenitsu’s arc is about overcoming his insecurities and proving to himself and others that he is capable of being brave and strong, even if it doesn’t always come naturally. Despite his initial lack of confidence, Zenitsu becomes a valuable and reliable member of the Demon Slayer Corps, showcasing themes of personal growth, determination, and courage.
