It's a common query, but let's clear the air right away: Zenitsu Agatsuma, the electrifyingly timid yet powerful Demon Slayer, is not a character in the strategic mecha anime, Code Geass. Zenitsu is one of the beloved protagonists from the globally acclaimed series, Demon Slayer: Kimetsu no Yaiba. While it's easy to mix up characters from different anime universes, understanding Zenitsu's actual age and context within his own story is crucial to appreciating his unique journey.
This hub article will clarify Zenitsu's real age, delve into how his youth shapes his character, and connect you to everything you need to know about him in the Demon Slayer universe.
Unpacking Zenitsu's True Series and Age
Zenitsu Agatsuma is officially 16 years old during the main events of Demon Slayer: Kimetsu no Yaiba. This makes him the oldest among the main trio, with Tanjiro Kamado and Inosuke Hashibira both being 15. His age has been consistently confirmed across the manga, official character data books, and profiles published by Shueisha. Born on September 3rd, he falls under the Virgo zodiac sign, a detail that many fans find ironically fitting given his often-anxious personality. For a complete breakdown of Zenitsu's age across his journey in Demon Slayer, explore our detailed timeline: .
The Impact of Zenitsu's Youth on His Character
Zenitsu's age of 16 plays a significant role in defining his personality, his struggles, and ultimately, his growth. His often-overwhelming anxiety, profound fear of death, and a comedic obsession with finding a wife are all hallmarks of a teenager grappling with immense trauma and responsibility. Despite his cowardly exterior, this phase of his life grants him distinct advantages. His adolescent body possesses lightning-fast reflexes and a quicker recovery rate, which are indispensable for mastering his specialized Thunder Breathing techniques.
However, his youth also means he sometimes lacks the sheer stamina and mental fortitude seen in older, more seasoned Demon Slayers. Zenitsu's arc is a quintessential coming-of-age story, where he slowly learns to harness his incredible power and confront his fears.

Zenitsu's Core Traits and Abilities
At his core, Zenitsu is a character defined by paradox. He appears timid, pessimistic, and suffers from low self-esteem. Yet, when pushed to his absolute limit or rendered unconscious by fear, his subconscious takes over, transforming him into a calm, precise, and incredibly powerful Demon Slayer. Under the tutelage of the former Thunder Hashira, Jigoro Kuwajima, Zenitsu mastered only one form of Thunder Breathing, but he refined that single technique—"Thunderclap and Flash"—to an extraordinary degree, even performing it sixfold. Upon waking, he rarely remembers his unconscious exploits.

Navigating Relationships and Age Dynamics
As a 16-year-old, Zenitsu's relationships with his peers are full of typical teenage complexities, from rivalry to deep friendship. He shares a profound bond with Tanjiro and Inosuke, forming the iconic main trio, and his persistent, if often comical, affection for Nezuko Kamado is a key element of his character. In the series' epilogue, Zenitsu is shown as an adult in his twenties, happily married to Nezuko, showcasing the culmination of his journey and growth. Discover how Zenitsu's relationships with Tanjiro, Nezuko, and others are shaped by his youthful perspective and his place in the group dynamic: .
Zenitsu in the Larger Demon Slayer Context
Comparing Zenitsu's age to other characters in Demon Slayer further contextualizes his journey. Inosuke Hashibira is 15, while others like Kanao Tsuyuri and Genya Shinazugawa are also 16, placing them squarely in the same developmental stage. Nezuko Kamado is chronologically 14 years old. The formidable Hashira, while a diverse group, typically range from 14 to 27 years old, with Muichiro Tokito being the youngest at 14, and Giyu Tomioka at 21 and Tengen Uzui at 23. Even the demons, like Muzan Kibutsuji, possess lifespans spanning millennia, highlighting the transient nature of human youth in contrast. See how Zenitsu's age stacks up against the vast array of characters in Demon Slayer, from his fellow trio members to the formidable Hashira: .
Clarifying the Code Geass Connection
To reiterate, Zenitsu Agatsuma is unequivocally a character from Demon Slayer: Kimetsu no Yaiba. He does not appear in Code Geass. Code Geass features its own iconic cast, including the brilliant and manipulative Lelouch Lamperouge, the stoic and conflicted Suzaku Kururugi, and the mysterious C.C.
