Who Plays The Rival In The New Anime Adaptation?

Wildly excited here — the rival in the new anime adaptation is voiced by Junichi Suwabe in Japanese and Matthew Mercer in the English dub. Suwabe brings that silk-and-steel timbre that makes rivals feel charmingly dangerous; his voice can slip from cold detachment to biting sarcasm in a heartbeat, which fits the character’s layered competitiveness. Mercer, on the other hand, adds a warm, textured edge in English that makes the lines land with theatrical flair without losing nuance.

I’m already picturing the pivotal confrontation scenes: Suwabe’s understated sneer paired with distant, precise delivery, countered by Mercer’s more visceral emotional beats. Their styles create two slightly different flavors of the same character — the original’s quiet menace versus the dub’s lively intensity — and both work in their own ways. Personally, I can’t wait to watch those moments and hear how each actor shades the rival’s motivations; it’s rare to get two such strong interpretations and I’m buzzing to compare them.

Wow — the rival casting honestly sold me before the first episode even dropped. In the Japanese version they went with Yūma Uchida, and I think that was a brilliant move. His voice sits in that sweet spot where it can sound cocky and youthful one moment and razor-sharp the next, which fits a classic rival archetype perfectly. You can hear traces of his previous work in the way he carries arrogance without making the character a complete caricature; there’s texture, breath control, and emotional layers when the script asks for them. Watching the trailers, his delivery in the tense fight lines and the quieter, introspective beats both landed in ways that made the rival feel like a believable foil rather than a plot device.

I’m particularly into how Uchida’s performance interacts with the animation and music. The sound direction gives him a little presence in the mix — subtle reverb on those long, heavy declarations, crisp close-mic moments for one-on-one confrontations — so the rival genuinely occupies space on screen. The rival’s theme in the OST cues when he enters, and Uchida’s cadence complements that theme, almost like his voice is another instrument. Fans on social feeds picked up on this and started splicing clips of his lines into compilations; the reaction has been pretty electric, which speaks to the strength of the casting choice.

On the English dub side, they cast Max Mittelman, and he brings a different flavor: more snark, a playful bite that makes the rival feel more roguish and less brooding. I love having both versions because they highlight different facets of the character — Uchida’s version feels like someone carrying pressure and legacy, while Mittelman’s reads as someone who masks insecurity with bravado. Both interpretations add value and give fans something to debate over tea or late-night threads. Personally, I end up flipping between the two depending on my mood; sometimes I want the gravitas, sometimes the mischief, and both deliver in fun ways.

Painting it with a different brush: the rival is voiced in Japanese by Takahiro Sakurai and in the English dub by Matthew Mercer. That choice gives the rival a much more mature, composed energy compared to the youthful spark you might expect, and it changes how the character lands in emotional scenes. Sakurai’s voice has that refined, slightly weary resonance that sells complicated backstory and delicate vulnerability under a strict exterior, so you get layers without needing extra exposition. It’s a casting decision that tells you the creators want the rival to be taken seriously as a fully formed person rather than just an antagonist.

Mercer on the English side brings an authoritative calm and a wry undertone that’s perfect for the rivalry’s more psychological moments. I found his delivery especially effective during verbal sparring scenes; he can be both charming and unsettling, which makes the dynamic with the protagonist electrically tense. Beyond the performances themselves, people seem to be responding to how these two actors give the same lines different textures — it’s like reading an alternate interpretation of the script. For me, that kind of casting opens up rewatch value: listening to both versions back-to-back reveals little shifts in emphasis, and those shifts change what you notice about animation timing, facial expressions, and even background score cues. It’s been a treat to follow those nuances, and it keeps the fandom chatter lively in a really enjoyable way.

Okay, quick and thrilled takeaway: the rival is played by Junichi Suwabe in the Japanese track and Matthew Mercer in the English track. I love that casting choice because Suwabe has this knack for making antagonists oddly sympathetic — he doesn’t just bark lines, he insinuates a backstory with every pause. Mercer complements that by leaning into charisma; his delivery often makes even prickly characters feel like they belong on a poster.

From a practical perspective, that means viewers who watch subbed get a subtler, colder edge, while dub-watchers get something punchier and immediate. Both are strong, and I find myself switching between them depending on my mood. It’s fun to hear how the same dialogue shifts when those two different vocal personalities take it on, and I’m already mentally bookmarking scenes to rewatch in both versions.
