Zenitsu is recognized by his distinctive yellow hair and eyes, a visual trait that sets him apart. Despite his role as a Demon Slayer, Zenitsu is often perceived as cowardly and fearful, harboring self-doubt. However, his strong sense of duty compels him to protect others, even at the risk of his life. This commitment is evident in his determination to fulfill his master Jigoro Kuwajima’s last wish.

What defines Zenitsu Agatsuma’s Personality and Background?
Zenitsu Agatsuma, a captivating character in the ‘Demon Slayer’ series, exhibits a unique blend of fearfulness and bravery, coupled with a deep affection for Nezuko Kamado.
Zenitsu, of average height, possesses fair skin, downward-sloped, worried-looking eyes transitioning from soft brown to gold, and forked eyebrows fading into a warm orange color. His short, yellow hair, a result of a lightning strike during training, falls unevenly in front of his face, resembling a bowl cut. Following the Mount Natagumo battle, temporary limb shrinkage due to Son’s poison is rectified by Shinobu Kocho‘s developed medicine.
He adorns a paler brown Demon Slayer uniform, featuring a dark brown gakuran jacket, a white belt, extended hakama pants, and his signature white-triangle patterned, yellow and orange gradient haori. Additional accessories include Kyahan with three white bows, matching the haori pattern, pale brown tabi socks, and white-laced zōri sandals.
Initially depicted as cowardly, Zenitsu often expresses fear, anxiety, and pessimism. However, beneath this exterior lies a brave and determined soul. His unconscious bravery surfaces when asleep or unconscious, transforming him into a powerful warrior, exemplified in the fight against the Spider Demon on Mount Natagumo. Zenitsu’s deep infatuation with Nezuko, despite her demonic nature, showcases his ability to recognize her inherent kindness and humanity.
Throughout the series, Zenitsu undergoes significant growth, gaining confidence and control over his fear through demon battles and protecting friends. Dressed in a lighter brown variation of the standard Demon Slayer attire, including a dark brown gakuran jacket, a white belt, extended hakama pants, and a distinctive haori with a white-triangle pattern on a yellow to orange gradient, Zenitsu completes his outfit with Kyahan featuring three white bows, pale brown tabi socks, and zōri sandals with white laces. Zenitsu embodies the struggle between fear and bravery, with his journey highlighting that courage is not the absence of fear, but the determination to persevere despite it. His character development, relationships, and unique abilities contribute to his status as one of the ‘Demon Slayer’ series’ most beloved characters.
Before the Infinity Castle raid, Zenitsu exhibits a different, more serious vibe, reflecting a newfound focus. This change follows a letter from Chuntaro revealing his master’s death and Kaigaku’s involvement. In his confrontation with Kaigaku, Zenitsu adopts a stern and enraged demeanor, displaying unexpected maturity compared to his usual cowardice.
Zenitsu also plays a major role in the Hashira Training Arc of Demon Slayer: Kimetsu no Yaiba, where he and his friends Tanjiro and Inosuke train with the Hashira, the highest-ranking members of the Demon Slayer Corps, to improve their fighting abilities and prepare for their final battle against Muzan Kibutsuji.
