Demon Slayer: Kimetsu no Yaiba is currently working hard on the anime's third season, and the star behind Zenitsu Agatsuma has revealed their secret to getting Thunder Breathing just right! Zenitsu serves as one of the core trio of fighters in Koyoharu Gotouge's original franchise, and that is definitely something you might not have expected following his original introduction to Tanjiro Kamado. But as we see through the course of the fights so far, Zenitsu is also secretly much stronger than he himself realizes and that's likely a tough balancing act for those behind the character bringing him to life.
The team behind Demon Slayer's anime was one of the many teams in attendance holding a special panel during Anime Expo earlier this month (of which ComicBook.com was in attendance), and it was here that voice actor Hiro Shimono revealed that his secret to voicing Zenitsu while he fights in his sleep is to somehow speak as much under his breath as he can. It was hard for the actor to nail down voicing the character while he's asleep, so he had to do some extra work in order to make sure it came out well in the final project.
As Shimono had explained, it was hard to act for Zenitsu during the fight scenes because the fighter is asleep the entire time. He had to work with ADR to find a way to properly monologue and make it under his breath in order to better sell the fact that the fighter was unconscious. When Zenitsu taps into stronger versions of his Thunder Breathing, Shimono explained that he loves to get louder with these bits in order to better sell the impact with fans. When Tanjiro star Natsuki Hanae spoke about working with Shimono, he noted how hilarious the actor is.
Noting that Shimono would regularly do push ups in between breaks, Shimono is known for giving his all during every recording. Shimono also explained that he loved doing the proposal scene with Nezuko because of how important it was to each of the characters. But we'll soon see much more from Zenitsu when Demon Slayer returns with the third season (which currently has no release window or date) in the near future.
