Isekai Quartet3 Episode9: Music Contests, Troll Buttons, and Why This Chaos Is Unbeatable

If you thought Isekai Quartet3 couldn’t get more wild, Episode9 just dumped a music contest into the mix—and let’s be real, it’s exactly the chaotic energy we signed up for. One minute, Kazuma’s fumbling with a cello (yes, cello—stop calling it a violin, MAL commenters are fighting over this), the next, there’s a mysterious button that might send everyone back to their original worlds… but let’s be honest, no one actually thinks it works.

First off, the big setup: Class1 vs Class2 in a music battle. Why? Because whoever wins gets to press that button. But here’s the tea—every fan on MAL is lowkey convinced the button is a total troll. Like, one comment said, “that button isn’t gonna do shit probably” and honestly? Same. Imagine if it just plays a fart sound or something? Classic Isekai Quartet move—they love messing with us.

The character moments this episode had me cackling. Albedo practically melting when she offers to give Ainz private music lessons? Girl, calm down—we see you simping hard. And Cid with the piano? Shadow Sama’s gonna slay that solo, right? Also, Subaru’s speech about whether they want to stay or go—some fans were shocked Tanya wants to return (wait, didn’t she just beg for downtime last season?). And don’t get me started on the power scaling debates: who’s gonna dominate the contest? Ainz (stop time and play perfect notes?), Shadow (edgy piano vibes?), or Reinhard (who’s probably hiding a Grammy-worthy voice)? Most fans say Ainz takes the cake, but Reinhard’s wild card status is keeping everyone guessing.

Some fans are saying Shadow Garden is ruining the vibe (“too many series, not enough time for everyone”), but I disagree—more chaos = more fun. And the ending tease? Is this the last season? Or is the button just a setup for Season4? One comment even joked that after winning, they’ll press the button and get a Season4 announcement instead—chef’s kiss, that’s exactly the energy we need.

At the end of the day, Episode9 is pure Isekai Quartet magic: silly, relatable, and full of moments that make you go “wait, what?” Whether you’re here for the music contest drama or the endless debates about the button, this episode has something for everyone. And let’s be real—we’re all just waiting for Shadow to drop that piano solo. Can’t wait for next week!

P.S. If Kazuma somehow wins the contest with his cello skills, I’m gonna lose my mind. No way that guy can play anything without messing up.
