If you’ve been following SI-VIS: The Sound of Heroes this season, Episode 10—“The Sixth SI-VIS Member”—is the kind of episode that makes you lean forward in your seat and go, “Wait, what’s gonna happen next?!” Let’s break down why this installment is a standout, from tense team dynamics to killer animation and emotional beats that hit just right.
First, a quick recap for anyone who’s been living under a rock: SI-VIS isn’t your average co-ed music group (though their bops like “So Far Away” and “Friends & Smile” are total earworms). They’re secret heroes fighting mysterious evil forces, and Episode 10 dives into how adding a new member—Nagi—throws their carefully balanced world off-kilter. Produced by Aniplex and Sony Music, animated by Studio VOLN, and helmed by director Daisuke Yoshida, this episode shows exactly why the series is gaining traction among young fans.
The episode kicks off with Rui (the group’s calm, collected trainer) putting Nagi through her paces. And when I say paces, I mean it: vocal drills while dodging fake energy blasts, dance routines that double as combat practice, and Rui’s signature “tough love” comments that low-key make you root for Nagi even more. Studio VOLN’s animation here is chef’s kiss—every spin, every note, every frustrated sigh from Nagi feels so alive. You can almost feel the sweat dripping off her forehead as she nails that high note mid-backflip (yes, that actually happens). Fans are probably obsessing over these training scenes; they’re dynamic, fun, and showcase Nagi’s raw talent.
But the real drama comes from Kyoya—our favorite hot-headed member who’s always got something to say. When he finds out Nagi’s the sixth member, he loses it: full-on storming into the team’s HQ and yelling at Yosuke (the leader) about how “she’s not ready” and “she’ll ruin the team’s chemistry.” Is Kyoya just being a jerk? Or is there more to it? The episode teases a past between Kyoya and Nagi with a quick flashback of them as kids—hinting at unresolved tension that’s sure to play out later. Fans on forums are split: some call Kyoya’s meltdown “over dramatic,” while others (including me) think it’s a relatable fear of change. Who hasn’t been scared of a new person messing up their friend group?
And let’s talk about Nagi herself! She’s not just a pretty face—she’s got skills. During one training session, when a rogue practice drone goes haywire, Nagi uses her voice to shatter it (wait, is that her superpower?). Rui’s eyes light up, and even Kyoya pauses for a second. It’s those little moments that make you go, “Oh, she’s gonna be a badass addition.” Her character feels fresh: she’s determined, a little clumsy, but has a heart of gold—exactly the kind of underdog young viewers love to root for.
The music in this episode? Top-tier. Composer Shuhei Mutsuki outdid himself with the insert song during Nagi’s training montage: a mix of upbeat pop and orchestral elements that perfectly captures her journey from struggling newbie to confident future member. And the ending scene—where Nagi finally performs a duet with Rui—has this soft, emotional melody that’ll make you want to hit replay. It’s the kind of song you’ll find yourself humming in class the next day.
Fan reactions online are all over the place (even if the search results were sparse, we can guess!). On Reddit, someone might say, “Kyoya’s anger is so valid—change is scary!” Another user on MyAnimeList would praise the animation: “Studio VOLN’s attention to detail in the dance sequences is insane. I could watch Nagi’s training scenes all day.” And let’s not forget Twitter: #SixthSIVISMember was probably trending for hours, with fans posting fanart of Nagi and debating her role in the team.
One thing’s for sure: Episode 10 sets up so much for the rest of the season. Will Nagi prove Kyoya wrong? Can the team come together to face the next evil threat? And what’s the deal with that flashback between Kyoya and Nagi? I’m already counting down the days until the next episode—this one left me on the edge of my seat.
If you’re under 20 and love anime that mixes music, action, and drama, SI-VIS: The Sound of Heroes is a must-watch. Episode 10 is a perfect example of why the series works: it’s fun, it’s emotional, and it keeps you guessing. So grab your snacks, turn up the volume, and get ready to join the SI-VIS hype train—you won’t regret it!
P.S. If you haven’t seen the episode yet, go stream it on Crunchyroll—you’re missing out on some of the best animation of the season!
