Zenitsu Agatsuma – Demon Slayer: Kimetsu no Yaiba Infinity Castle (2025) Character & Voice Actor

Zenitsu Agatsuma in Demon Slayer: Infinity Castle (2025) – Crying, Screaming, Then Suddenly OP

Let’s be honest Zenitsu Agatsuma is pure chaos wrapped in yellow. If you’ve seen Demon Slayer, you already know how it goes: one minute he’s on the floor having a panic attack, begging for his life… and the next he’s literally slicing demons in half with one insane Thunder Breathing move. Like… what even is this guy?! Anxiety + power = iconic.

But seriously, Zenitsu wouldn’t hit nearly as hard (or be nearly as funny) without that voice. His voice acting? Absolute gold.

Japanese VA: Hiro Shimono

Hiro Shimono is Zenitsu. The screaming, the whining, the “I’m gonna diiiie!” freakouts — that’s all him. And somehow, he makes it hilarious. But what’s cool is, when Zenitsu finally stops crying and does something badass (usually while unconscious, lol), Hiro completely switches it up — smooth, calm, and deadly. The duality is real.

Also, side note: he’s the same guy who voices Connie from Attack on Titan and Dabi from My Hero Academia. So yeah… man’s got serious range.

🇺🇸 English VA: Aleks Le

Dub watchers, don’t worry — Aleks Le nails it. His Zenitsu is just as over-the-top, loud, and loveable. Every breakdown? Hilarious. Every heroic moment? Chills. And yep, he absolutely crushes the screaming (you know the one).

He somehow makes Zenitsu feel annoying and precious at the same time — which is honestly a skill. When Zenitsu finally gets his big moments in the Infinity Castle arc, Aleks brings the fire. You’re gonna feel it.
