Iruma-kun Season 4: Why This Might Be the Anime’s Best Arc Yet (Fan Perspective & Story Breakdown)

If you’ve been following Welcome to Demon School! Iruma-kun from the beginning, you already know this series has a very special identity—chaotic humor, heartfelt character growth, and moments that unexpectedly hit much harder than you would expect from a comedy-focused anime.

With Season 4 approaching in April 2026, the excitement in the community isn’t just about the return itself, but about how much of the story will actually be adapted and whether this season could become the strongest entry in the entire series so far.

Based on pacing trends from previous seasons, manga structure, and typical adaptation rhythm, Season 4 is shaping up to be one of the most content-rich installments yet.

How Many Chapters Will Season 4 Cover?

The most realistic expectation is that Season 4 will adapt roughly Chapters 147 to around 195–200, giving us approximately 45–50 chapters of content. This fits the established adaptation pattern of about two manga chapters per episode, especially considering the series tends to slow down for emotional scenes and comedic timing.

Here is how the previous seasons were structured:

This consistency is one of the reasons fans feel confident about pacing predictions. The studio has been careful not to rush the story, which is especially important for a series that depends heavily on character interactions and emotional development rather than pure action.

The Music Festival Arc: The Heart of Season 4

The first major storyline of Season 4 is the Music Festival arc, spanning roughly Chapters 147 to 180. This arc is widely considered one of the most important in the series because it shifts the focus away from survival-based competition and toward expression, teamwork, and personal identity.

After the intense physical trials of the Harvest Festival, the Misfit Class now faces a completely different challenge: proving their worth through performance and coordination.

Why This Arc Stands Out

• It focuses on emotional and creative growth instead of combat
• It strengthens the bond between Misfit Class members
• It delivers major character development moments
• It introduces long-awaited spotlight moments for overlooked characters

One of the most anticipated highlights is the introduction and full focus on Purson Soi, a character who has been present since the beginning but remained almost completely hidden from the spotlight. His reveal is not just comedic—it significantly changes how the class dynamic is perceived.

Expected Episode Structure

If Season 4 follows the usual two-cour structure (24 episodes total), the pacing could realistically look like this:

• Episodes 1–15: Training, preparation, and early conflict buildup for the Music Festival
• Episodes 16–18: Full Music Festival performances
• Episodes 19–23: Akudol Games arc
• Episode 24: Aftermath, character conclusions, and emotional setup for future arcs

This structure allows the Music Festival to breathe properly rather than being rushed, which is crucial because this arc relies heavily on performance buildup and emotional payoff.

Why the Music Festival Could Shine in Anime Form

Unlike manga panels, the anime adaptation has a unique advantage here: music and performance can be fully realized. This means actual songs, voice acting performances, and animated choreography will replace static imagery, potentially elevating the entire arc beyond its original format.

If handled correctly, this could become one of the most memorable sections in the entire series, not just narratively but also musically and visually.

The Akudol Games Arc: A Lighter but Important Transition

After the emotional intensity of the Music Festival, Season 4 is expected to transition into the Akudol Games arc, which spans roughly Chapters 181 to 190+. While significantly shorter, this arc plays an important role as a tonal shift.

It brings back the series’ comedic energy while still contributing to character development in subtle ways. It also reintroduces one of the most entertaining alternate personas in the series, adding a refreshing contrast after the heavier storyline of the Music Festival.

Why This Arc Works as a Season Finale Section

• Short and fast-paced compared to the previous arc
• Heavy focus on humor and entertainment
• Provides closure for multiple character threads
• Acts as a bridge toward future emotional developments

Characters like Alice Asmodeus and Kerori Crocell also get opportunities to shine in unexpected ways during this arc, especially in the competitive idol-style setting, which fits the series’ chaotic tone surprisingly well.

The Emotional Core: Iruma and Ameri

If the season extends toward Chapter 195–200, it will likely reach one of the most emotionally significant developments in the story involving Iruma and Ameri Azazel. While the series does not rush romance, these subtle developments carry a lot of emotional weight for long-term viewers.

This moment is expected to serve as one of the emotional anchors of the season finale, giving fans a satisfying yet open-ended conclusion that naturally sets up future story developments.

Why Season 4 Pacing Matters So Much

One of the biggest strengths of Iruma-kun as a series is its pacing philosophy. It does not rush through major arcs or sacrifice character moments for speed. Instead, it focuses on building relationships, comedic timing, and emotional payoff gradually.

Season 4 is particularly important because it represents a shift in the Misfit Class from underdogs to a more recognized and capable group within Babyls. That transition requires careful storytelling to feel earned rather than forced.

Final Thoughts

Season 4 of Welcome to Demon School! Iruma-kun is shaping up to be a defining moment for the series. With roughly 45–50 chapters expected to be adapted, it brings together two major arcs that balance emotional depth, character growth, and comedic energy.

If the adaptation maintains its steady pacing and respects the source material, this season could easily become the most well-rounded and impactful entry in the entire anime so far. From long-awaited character reveals to musical performances and emotional payoffs, everything is aligning for a standout season.

For fans, this isn’t just another continuation—it’s the moment where the Misfit Class truly steps into a new era.
