How Old Is Zenitsu Agatsuma In Dragon Ball Z? He Isnt

Let's clear the air right away: Zenitsu Agatsuma, with his distinctive yellow haori and lightning-fast reflexes, is absolutely not a character from Dragon Ball Z. While both are incredibly popular anime franchises, they exist in entirely separate universes, created by different authors, and follow distinct storylines.
Zenitsu Agatsuma is a core member of the Demon Slayer Corps, a protagonist from Koyoharu Gotouge's phenomenal series, Demon Slayer: Kimetsu no Yaiba. So, if you're looking to understand more about his age, character, and journey, you've come to the right place – we'll be diving deep into the world he actually inhabits!

Unpacking the Universe: Why Zenitsu Isn't in Dragon Ball Z

The confusion is understandable; both Demon Slayer and Dragon Ball Z feature powerful characters, intense battles, and incredible transformations. However, they are two distinctly separate entities. Dragon Ball Z, created by Akira Toriyama, follows the adventures of Goku and his friends as they protect Earth from various villains using ki-based martial arts and super-human strength.
Demon Slayer, on the other hand, is a historical fantasy set in Taisho-era Japan, focusing on a boy named Tanjiro Kamado who becomes a demon slayer to avenge his family and cure his sister, Nezuko. Zenitsu Agatsuma is one of Tanjiro's closest companions, a swordsman who uses the Thunder Breathing technique to combat demons. The art styles, power systems, and overarching narratives of these series are fundamentally different, making it impossible for Zenitsu to appear in Goku's world.
