Why the Music Festival Is Iruma-kun’s Most Heartfelt Arc Yet

There are anime sequels you watch out of habit, and then there are sequels you genuinely miss. For me, Welcome to Demon School! Iruma-kun falls into the second category.

After the chaos, comedy, and surprisingly emotional moments of the Harvest Festival storyline, I honestly wondered how Season 4 could possibly keep the same momentum going.

But after the first few episodes, it’s clear this season isn’t trying to outdo the action — it’s aiming straight for the heart instead.

And somehow, that works perfectly.

The return to Babyls Demon School feels warm, chaotic, colorful, and weirdly comforting in the best way possible. Season 4 shifts the focus away from survival games and dangerous exams toward music, self-expression, and the bonds between the Misfit Class members.

Iruma-kun Season 4 Episode 7: Why the Hype for the Music Festival Is Real

It sounds lighter on paper, but emotionally? This might become the strongest arc in the entire anime.

A Different Kind of Arc — and That’s Why It Works

A lot of shonen-style anime fall into the trap of constantly trying to “go bigger.” Bigger fights. Bigger villains. Bigger transformations. What makes Iruma-kun refreshing is that it understands character moments can be just as exciting as battles.

The Music Festival Arc proves exactly that.

Instead of fighting monsters in a forest like last season, the Misfit Class now has to perform on stage and earn recognition through talent, creativity, and teamwork. It sounds ridiculous at first — because it absolutely is — but that absurdity is part of the charm that makes the series so lovable.

What surprised me most is how naturally the emotional themes fit into the story. Underneath the comedy and exaggerated demon-world nonsense, Season 4 quietly explores identity, confidence, and the fear of being truly seen by others.

And honestly? That hits harder than another tournament arc ever could.

Purson Soi Finally Steps Into the Spotlight

If there’s one reason manga readers have been hyping this season for years, it’s Purson Soi.

Technically, he has been part of the class since the beginning. The anime constantly hid him in plain sight as a long-running visual joke because of his family’s bloodline magic that allows him to erase his presence completely. But Season 4 finally gives him real focus, and it immediately turns him into one of the most interesting characters in the cast.

His struggle feels surprisingly relatable. Purson comes from a family that values silence and invisibility, yet he secretly loves music and performance. That conflict between tradition and personal passion becomes one of the emotional cores of the season.

It’s the kind of storyline Iruma-kun excels at — taking a goofy supernatural concept and turning it into something genuinely human.

The anime also deserves credit for how carefully it handles his introduction. Instead of forcing drama immediately, the series slowly lets the audience connect the dots, making his presence feel meaningful rather than random.

The Misfit Class Continues to Carry the Series

One reason I think Iruma-kun has stayed consistently enjoyable across four seasons is because the supporting cast actually matters.

Too many anime introduce huge classroom rosters only for half the characters to become background decoration forever. Here, almost every member of the Misfit Class gets moments to shine, even during smaller comedic scenes.

Season 4 especially benefits from this ensemble energy because the Music Festival Arc depends entirely on teamwork. Watching these wildly different personalities attempt to create something together leads to some of the funniest scenes the anime has done in years.

Standout Characters This Season

• Clara, who somehow becomes even more chaotic every episode.
• Ameri, whose scenes with Iruma continue to fuel one of anime’s most wholesome slow-burn romances.
• Jazz and Allocer, who unexpectedly steal several comedy moments.
• Keroli/Kuromu, who reminds everyone that demon idols are apparently serious business.

The chemistry between the cast feels effortless now. Four seasons in, Babyls Academy genuinely feels alive.

The Music Festival Could Become the Anime’s Best Animated Sequence

Fans on Reddit and anime forums have been talking nonstop about one specific moment: the “Lilith Red Carpet” performance.

Without spoiling anything major, manga readers consider it one of the defining scenes of the entire series. And honestly, after seeing the production quality in the early episodes, I understand why expectations are so high.

The animation studio seems to know how important this arc is for fans.

Expressions are sharper, musical scenes feel more dynamic, and the color design has become noticeably more vibrant compared to previous seasons. Even small performance sequences already feel more polished than expected for a long-running comedy anime.

Music-focused anime arcs are difficult because viewers instantly notice weak vocal performances or awkward staging. But so far, Season 4 feels surprisingly confident.

If the studio nails the big festival moments later this season, this could easily become the most memorable part of the anime so far.

Iruma and Ameri Still Have Incredible Chemistry

I’ll be honest — part of the reason I keep coming back to Iruma-kun is the relationship between Iruma and Ameri.

The series never rushes the romance, which actually makes every tiny interaction feel meaningful. A single awkward conversation between them somehow carries more emotional weight than entire romance arcs in other anime.

Season 4 seems to be slowly pushing their relationship forward again, especially with rumors that the anime may adapt the Deviculum Arc later this year.

For longtime fans, that possibility is exciting for one major reason: the dance scene.

If you know, you know.

And if the anime really reaches that point by the finale, social media is going to explode.

Why the Tone Shift Feels So Refreshing

Some viewers expected Season 4 to immediately continue the intense atmosphere of the Harvest Festival. Instead, the anime deliberately slows down and becomes more character-focused.

Personally, I think that was the smartest decision possible.

The series needed breathing room after the nonstop pressure of Season 3. By focusing on music and emotional growth, the anime gives its characters space to evolve naturally instead of constantly throwing them into danger.

That slower pacing also helps reinforce what Iruma-kun does best: balancing comedy with sincerity.

One minute you’re watching absurd demon-school humor, and the next the anime quietly delivers an emotional character moment that genuinely catches you off guard.

Very few long-running comedy anime maintain that balance this consistently.

Season 4 Release Schedule and Episode Count

Season 4 is expected to run for 24 episodes, continuing the franchise’s two-cour format. New episodes are currently airing weekly on Saturdays.

The longer episode count is especially good news because it gives the anime enough room to properly adapt multiple manga arcs without rushing important moments.

And honestly, Iruma-kun benefits a lot from slower pacing. The emotional scenes land better when the series takes time to let characters breathe.

Final Thoughts

At this point, Welcome to Demon School! Iruma-kun feels like one of the most consistently enjoyable anime franchises of the past several years. It may not dominate mainstream anime discussions the same way giant battle shonen do, but it understands something equally important: people become attached to characters they genuinely enjoy spending time with.

Season 4 already feels special because it embraces everything fans love about the series instead of trying to reinvent it.

• The comedy is still ridiculous.
• The characters are still lovable.
• The emotional moments still sneak up on you when you least expect them.
• The music performances add a completely fresh energy to the story.

And now it also has music performances, emotional character arcs, and potentially one of the strongest payoffs in the entire adaptation ahead of it.

Honestly, I missed this weird demon school more than I realized.
