SI-VIS: The Sound of Heroes Season 1 Episode 10 Review: When Music Meets Mayhem (And It Slaps)

Okay, let’s cut to the chase—if you haven’t watched Episode 10 of SI-VIS: The Sound of Heroes yet, drop whatever you’re doing (yes, even that TikTok scroll) and go hit play. This episode is the perfect mix of bops, badass battles, and character feels that’ll have you screaming into your pillow by the end. Let’s break it down, guys.

First, a quick recap for anyone who’s been living under a rock: SI-VIS is this global co-ed vocal group (led by the charismatic Yosuke) that’s taking the world by storm with their fire performances. But here’s the tea—they’re secretly heroes fighting mysterious calamities that threaten to destroy everything. How do they do it? By harnessing the energy from their concert crowds as battle power. Genius, right? And let’s not forget the crew behind it: produced by Aniplex and Sony Music Entertainment Japan, animated by Studio VOLN, with music by Shuhei Mutsuki (who’s low-key a legend for this soundtrack).

Episode 10 kicks off with SI-VIS’s Tokyo dome concert—think 50,000 screaming fans, neon lights, and a setlist that’s pure ear candy. The opening number, “Echoes of Courage,” had me dancing in my seat (no shame). But halfway through the second song, chaos hits: a giant, shadowy calamity bursts through the stage floor. And here’s where the magic happens—SI-VIS doesn’t skip a beat. They switch from singing to fighting without the audience even noticing. Yosuke hits a high note while dodging a dark energy blast, and the backup dancers’ choreography suddenly turns into defensive moves. Fans on MyAnimeList were losing it over this scene: one user wrote, “The way they blended the concert and battle was chef’s kiss—like, I forgot I was watching an action scene because the music was so good.”

Let’s talk about character growth, because this episode delivered big time. Remember that shy vocalist, Aoi? She’s always been nervous about performing in front of huge crowds, but when the calamity targeted a group of fans in the front row, she stepped up. Her solo verse in the middle of the battle—“I’ll sing for you, I’ll fight for you”—hit different. The crowd’s cheers amplified her energy, and she unleashed a wave of light that pushed the calamity back. Fans on the forum were gushing: “Aoi’s moment was so empowering! I felt like I was right there cheering her on.” It’s the kind of character arc that makes you go, “Yes, queen!”

And let’s not sleep on the animation. Studio VOLN outdid themselves here. The concert scenes were vibrant—think sea of glow sticks, confetti, and Yosuke’s iconic smile that could light up a room. The battle sequences? Fluid, colorful, and full of creative touches—like energy blasts shaped like musical notes and the calamity’s shadows twisting into dissonant chords. One fan commented, “The way the crowd’s lights merged with the battle energy looked like a galaxy—my eyes were glued to the screen.”

But wait, it’s not all perfect. Some fans (including me) thought the calamity’s backstory was a bit vague this episode. We still don’t know where these things are coming from, or why they’re targeting SI-VIS. But honestly? The excitement of the concert and battle made up for it. Sometimes you just need to turn off your brain and enjoy the ride.

Another highlight: the ending scene. After defeating the calamity, SI-VIS goes back to performing like nothing happened. The crowd is none the wiser, and Yosuke gives a speech about “music bringing people together.” It’s cheesy, but in the best way possible. I may have teared up a little—don’t judge me.

For all you under-20s out there, this episode is exactly what we need: relatable characters, bangers you can add to your playlist, and action that’s not too dark. I stayed up until 2 a.m. watching it, and then replayed the concert scene three times (my parents were not happy, but worth it). And let’s not forget the cast—Ayane Sakura’s voice as Aoi is so soft but powerful, and Nobunaga Shimazaki nails Yosuke’s charm.

So, final verdict: Episode 10 of SI-VIS is a must-watch. It’s fun, emotional, and full of moments that’ll make you want to scream “SLAY!” at your screen. If you’re into music, action, or just cool stories about friendship and courage, this is the show for you. Can’t wait for the next episode—let’s hope it’s just as epic.

P.S. Add “Echoes of Courage” to your Spotify playlist. Trust me, it’s a bop.
