Many anime enthusiasts often wonder about the ages of beloved characters, and a common query we encounter is, "How old is Zenitsu Agatsuma in Fairy Tail?" It's a fantastic question, though it's important to clarify that Zenitsu Agatsuma is actually a central and unforgettable character from Demon Slayer: Kimetsu no Yaiba, not the magical world of Fairy Tail.
While Zenitsu doesn't wield magic alongside Natsu and Gray, his journey as a Demon Slayer is equally captivating and deeply influenced by his age. Here, we'll dive into everything you need to know about Zenitsu Agatsuma's age, how it shapes his personality, powers, and pivotal role in the fight against demons. Let's clear up any confusion and get right into the heart of his story!
Unpacking Zenitsu's Core Details: Age, Birthday, and Beyond
At the core of his character, Zenitsu Agatsuma is 16 years old during the majority of the main Demon Slayer storyline. This age is firmly established in the manga, official guidebooks, and character profiles, providing a clear reference point for his development. His birthday falls on September 3rd, making him a Virgo—a sign often associated with meticulousness and anxiety, traits Zenitsu certainly exhibits!

While the main narrative spans approximately two years, suggesting he likely celebrates his 17th birthday by the time of the final, climactic confrontation with Muzan, his primary experiences unfold during his sixteenth year.

The Teenage Team: Zenitsu's Age Among His Peers
Zenitsu isn't alone in his youthful struggle. He shares his age with the series' protagonist, Tanjiro Kamado, who is also 16 years old. He is just one year older than the wild and unpredictable Inosuke Hashibira, who is 15. Other notable peers like Kanao Tsuyuri and Genya Shinazugawa also stand at 16, forming a formidable generation of young slayers.
This contrasts sharply with the broader Demon Slayer Corps, particularly the Hashira, whose ages typically range from 14 (Muichiro Tokito, the youngest) to 27. Even the compassionate leader, Kagaya Ubuyashiki, is only 23. This youthful dynamic highlights the immense burden placed on these young heroes, especially when facing centuries-old Upper Rank demons and the millennia-old progenitor, Muzan Kibutsuji.
