Isekai Quartet 3 [Season 3]

Isekai Quartet 3: The Crossover Chaos Continues—But Is It Still Fresh?

If you’ve ever wondered what would happen if Kazuma’s chaotic energy collided with Ainz Ooal Gown’s overlord vibes, Subaru’s time-loop trauma, and Tanya’s military precision—all in chibi form—Isekai Quartet has been your answer for two seasons. Now, Season 3 is here, and it’s bringing a new face to the party: Cid Kagenou from The Eminence in Shadow. But does this third installment keep the laughs rolling, or is it starting to feel like a broken record? Let’s dive in.

First, let’s get the basics straight. Isekai Quartet 3 is the latest season of Kadokawa’s beloved crossover anime, where characters from KonoSuba, Overlord, Re:Zero, and The Saga of Tanya the Evil are transported to a mysterious new world via a “button” (because why not?). This time, though, the gang isn’t alone. Cid, the self-proclaimed “Shadow Sovereign” who thinks he’s living in a secret fantasy RPG, joins the fray, adding his own brand of edgy humor to the mix. The season premiered on October 13, 2025, with Studio PuYUKAI returning to animate it—so expect the same cute chibi designs and slapstick comedy that made the first two seasons a hit.

Now, let’s talk about the elephant in the room: the new addition. Fans have mixed feelings about Cid. Some are excited to see his over-the-top “shadow” antics clash with the group—like when he tries to act cool while everyone else is just trying to survive a random monster attack. One fan on MyAnimeList gushed, “It’ll be fun to see Cid join the gang,” and honestly, their enthusiasm is contagious. But others aren’t sold. “There are much better candidates for a new isekai quartet szn than that series,” one user grumbled. Fair point—The Eminence in Shadow is a divisive pick, but hey, variety is the spice of life, right?

The humor, as always, is the show’s bread and butter. Imagine Subaru panicking about a time loop while Kazuma is busy hitting on every female character (and failing miserably). Tanya, ever the strategist, is probably facepalming at their incompetence, while Ainz is… well, being Ainz—confused but trying to look cool. The chibi art style only amplifies the comedy; there’s something inherently funny about seeing a tiny Ainz trying to command an army of chibi minions.

But let’s be real: Isekai Quartet isn’t here to win awards for deep storytelling. It’s here to make you laugh, and it does that by leaning into the absurdity of its premise. One fan summed it up perfectly: “It’s just fan service no story main plot needed to follow.” And that’s okay! Sometimes, you just want to watch your favorite characters act like idiots for 10 minutes.

That said, not everyone is on board. A common complaint? The lack of progress in the original series. “Is it really that popular that they get updates faster than the original series?” one user asked, echoing the frustration of many Youjo Senki (The Saga of Tanya the Evil) fans who are still waiting for Season 2. Ouch—touche. It’s hard not to side-eye Kadokawa for prioritizing a crossover over continuing beloved main series.

But let’s focus on the positives. The animation, while simple (think Tomodachi Life levels, as one fan joked), is charming in its own way. The voice cast is stellar, with Seiichirou Yamashita stepping into Cid’s shoes and nailing his deadpan delivery. And let’s not forget the opening theme—“Isekai Concerto” by Ains, Kazuma, Subaru, and Tanya is a bop that’ll have you singing along in no time.

So, is Isekai Quartet 3 worth your time? If you’re a fan of the original series and love seeing your favorite characters in silly situations, absolutely. It’s a lighthearted escape that doesn’t take itself too seriously. But if you’re craving deep lore or character development, you might want to look elsewhere.

At the end of the day, Isekai Quartet 3 is like a fun reunion with old friends—chaotic, a little messy, but ultimately heartwarming. And let’s be honest: in a world full of heavy isekai dramas, sometimes you just need 10 minutes of chibi Kazuma yelling about “explosions” to brighten your day.

Final Verdict: 7/10. It’s not groundbreaking, but it’s a good time—especially if you’re already invested in the crossover crew. Just don’t hold your breath for Youjo Senki Season 2 anytime soon.

Now, if you’ll excuse me, I need to rewatch the first two seasons to prep for the chaos. 🎉
