Iruma-kun Season 4 Is Coming and the Demon School Is About to Get Real
Let’s be honest — when Iruma-kun Season 4 was confirmed, the fan community lost its collective mind. And rightfully so. Welcome to Demon School! Iruma-kun has spent three seasons quietly becoming one of the most wholesome, genuinely fun, and underrated shonen series running. Now, with the April 2026 premiere locked in and Bandai Namco Pictures back at the helm, the Demon School arc we’ve been begging for is finally landing. This is not a drill.
Whether you’ve been with Suzuki Iruma since episode one or you’re just now hopping on the hype train, this guide covers everything — where we left off, what’s coming in Iruma-kun Season 4, the arcs that are going to wreck you emotionally (in the best way), and why this show deserves a permanent spot in your must-watch list.

Quick Recap: How We Got Here (Seasons 1–3 in a Nutshell)
If you need to catch up before diving into Iruma-kun Season 4, here’s the condensed version — but honestly, go watch all three seasons. You won’t regret a single episode.
Season 1 — The Boy Who Became a Demon School Student
Suzuki Iruma is a 14-year-old human kid whose absolutely terrible parents sell him to a demon. That demon is Sullivan, a powerful elder of the Netherworld who desperately wants a grandson. Sullivan enrolls Iruma in Babyls Demon School and tells him to blend in, survive, and above all — never let anyone find out he’s human.
What follows is one of the most charming fish-out-of-water setups in shonen history. Iruma’s lifetime of surviving neglectful parents has accidentally made him incredibly talented at dodging danger, reading people, and adapting fast. The demon school thinks he’s a prodigy. He’s just traumatized and extremely good at faking it.
Season 1 introduces Iruma’s found family: Clara Valac (chaotic good energy personified), Asmodeus Alice (the loyalest rival you’ve ever seen), and his demon school homeroom teacher Kalego-sensei (perpetually furious, secretly caring). It also drops the first hints that Iruma has hidden potential far beyond what any of them — including him — understand.
Season 2 — Evil Cycle and the Dark Iruma Arc
Season 2 is where Iruma-kun proved it had serious storytelling chops. The Harvest Festival arc pushed every member of the Misfits Class to grow, but the crown jewel was the Evil Cycle arc — where Iruma slips into an alternate personality, dark and commanding, and accidentally becomes even more impressive as a demon than his normal self. Dark Iruma is terrifying. Dark Iruma is also hilarious. It’s the show at its absolute peak tonal balance.
Season 2 also deepened the ranking system that becomes central to Iruma-kun Season 4. Ranks in the Netherworld run from Aleph (1) to Tet (22). Most students never crack the double digits in their entire careers. Iruma, a human with zero magic, has been climbing. That contradiction is what makes the upcoming ranking battles so electric.
Season 3 — Ranking Battles Ignite
Season 3 brought the Harvest Festival to a close and set the stage for everything Iruma-kun Season 4 is going to deliver. The Misfits Class — formally the Abnormal Class — showed the demon school and the wider Netherworld that they aren’t a joke. And Iruma, time and again, demonstrated something that nobody in the Netherworld quite has a word for yet: genuine, earned goodness that somehow reads as demonic ambition.
By the end of Season 3, the stakes are higher, the threats are real, and certain sinister factions within the Netherworld have started taking notice of Iruma in ways that aren’t friendly. Which brings us right to where Iruma-kun Season 4 picks up.

Iruma-kun Season 4 — What We Know About the Arcs
Iruma-kun Season 4 is drawing from the manga’s later arcs, and the source material has been sitting on a goldmine. The tone shifts here — not in a way that loses the warmth and humor the series is known for, but in a way that adds genuine weight to everything. The Demon School gets serious. The ranking battles stop being just academic exercises. And Iruma’s position as a hidden human in the Netherworld stops feeling like a background gag and starts feeling like a ticking clock.
The Rank Advancement Examinations
Central to Iruma-kun Season 4 are the formal Rank Advancement Examinations. In previous seasons, rankings were attached to academic events and festivals. Now they become structured tests with real consequences — pass and you rise in the demon world’s social and magical hierarchy, fail and you stagnate. For Iruma, every advancement is a miracle wrapped in a headache. He has no inherent magic. He has Alam, the ring passed down from the demon lord, which grants him access to borrowed power. But borrowed power has limits. Watching him navigate the gap between where he ranks and what he can actually do is simultaneously nail-biting and deeply satisfying.
The ranking battles in Iruma-kun Season 4 aren’t just about Iruma either. His classmates — each of them bizarre, talented, and deeply lovable — are pushing their own limits. Asmodeus racing toward the top, Clara doing things that defy physics and demon logic both, and the wider Misfits Class proving over and over that unconventional doesn’t mean weak.
Iruma’s Identity Under the Microscope
The deeper arc of Iruma-kun Season 4 circles back to the central tension that has always powered this series: Iruma is human. In a world built for demons. And the longer he thrives, the more dangerous that secret becomes.
Season 4 puts Suzuki Iruma in situations where his humanity — his empathy, his instinct to protect people, his refusal to dominate or crush — becomes both his greatest asset and his most obvious tell. Demons don’t think the way he does. The fact that he keeps winning while thinking like a human is starting to raise questions that certain very powerful, very dangerous characters in the Netherworld are beginning to ask.
This tension elevates Iruma-kun Season 4 from a great comedy-adventure into something with real emotional stakes. You’re not just rooting for him to pass his exams. You’re rooting for him to survive being seen.

Sullivan and the Elder Council
Sullivan has always been equal parts hilarious doting grandfather and genuinely terrifying demon elder. Iruma-kun Season 4 tips the balance more toward the latter. The political dimension of the Netherworld — the Elder Council, the legacy of the Demon Lord, the power structures that Sullivan navigates — all of this comes into sharper focus. And the question of what Sullivan really knows about Iruma, and how far he’d go to protect him, gets a lot more urgent.
New Faces, New Threats
Without dropping manga spoilers that would cross into full-on leak territory, Iruma-kun Season 4 brings in characters who exist in direct opposition to everything Iruma represents. Not cartoonish villains — the series has always been too smart for that — but demons whose worldviews genuinely challenge the optimism that powers the show. They’re compelling. Some of them are even sympathetic. And they make Iruma-kun Season 4 feel like a series that has grown up alongside its protagonist.
Bandai Namco Pictures — The Animation Studio You Should Know
One of the things that makes Iruma-kun Season 4 such a confident bet is the continuity at the animation studio level. Bandai Namco Pictures has handled all three previous seasons, and their work on this series has been criminally underappreciated in the animation discourse.
The character designs are vivid and expressive in ways that serve comedy and drama equally. The Netherworld has a consistent visual vocabulary — dark, lush, slightly absurd — that never feels generic. And the action sequences, especially during ranking battles, have a kinetic quality that punches above the show’s production tier.
Bandai Namco Pictures isn’t the flashiest studio name in the conversation, but their dedication to Iruma-kun specifically shows in the details. The way Iruma’s expressions shift between terrified and accidentally intimidating. The visual grammar of the Evil Cycle transformations. The sheer chaos of Clara Valac’s summoning powers rendered on screen.
Knowing they’re back for Iruma-kun Season 4 means the visual identity stays consistent — and given how much of this season’s emotional weight depends on character performance, that continuity matters.

The Ranking System Explained — Because It’s Central to Everything in Season 4
If you’ve been vague on the details of the demon school ranking system, now is the time to lock it in — because the ranking battles in Iruma-kun Season 4 make it matter in a way previous seasons only gestured at.
Ranks in the Netherworld run from Aleph (Rank 1) all the way to Tet (Rank 22), which is the legendary Demon Lord rank. Most demons spend their entire lives below Dalet (Rank 4). Getting to Zayin (Rank 7) is considered remarkable. Iruma’s trajectory has been extraordinary by any metric — especially given that he technically shouldn’t be able to generate magic at all.
Here’s the breakdown that matters for Iruma-kun Season 4:
- Aleph–Gimel (1–3): Student range. Most Babyls students graduate around here.
- Dalet–Vav (4–6): Respected working demons. Teachers, low-tier officials.
- Zayin–Tet (7–9): Elite. Exceptional demons. Elder council territory starts here.
- Yod and above (10+): Legendary. Historical figures. Sullivan sits up here.
- Tet (22): Demon Lord. One seat. One demon in all of history.
The reason the ranking battles hit differently in Iruma-kun Season 4 is because the Abnormal Class has already cleared the ceiling everyone expected of them. Now they’re climbing into ranks that attract real attention from the Netherworld’s power structure. And Iruma, climbing without magic, is an anomaly that can’t stay invisible forever.

Why Iruma-kun Is the Best Family-Friendly Shonen Running Right Now
Let’s settle this debate properly, because it comes up in every fan thread and it deserves a real answer.
Welcome to Demon School! Iruma-kun — and specifically Iruma-kun Season 4 — occupies a lane in shonen that basically nobody else is working in right now. It’s not trying to be Demon Slayer. It’s not chasing the battle-shonen formula. It’s doing something rarer and, honestly, harder: it’s telling a story about a genuinely good person navigating a world built for the ruthless, and making that feel exciting.
It’s Actually Funny
Not “anime funny” in that background-gag way. Genuinely, consistently, laugh-out-loud funny. Clara Valac is a comedic force of nature. Asmodeus’s worship of Iruma escalates in ways that never get old. The entire Abnormal Class is a sitcom ensemble running inside a fantasy epic. Iruma-kun Season 4 keeps all of this — the humor doesn’t disappear as the stakes rise, it evolves. It becomes the pressure valve that makes the serious moments land harder.
It Has Something to Say
At its core, Iruma-kun is about a kid whose entire life has been defined by being used and discarded — and who, when dropped into a world full of powerful beings who could crush him, chooses to respond with kindness, connection, and genuine effort. That’s not a small idea. It’s actually a pretty radical one for shonen, a genre that often defaults to “get stronger and punch harder.”
Iruma-kun Season 4 is where that philosophy gets stress-tested the hardest. The world is going to push back. The question is whether Iruma — and by extension, the show — is willing to hold the line on what it believes.
You Can Watch It With Anyone
This is not a small point. Iruma-kun is one of those rare anime that genuinely works for an 8-year-old watching with a parent, a college student watching alone at midnight, and everyone in between. The humor operates on multiple levels. The emotional beats are universal. The action is exciting without being gratuitous.
If you’ve been looking for an anime to share with someone who’s skeptical of the genre, this is the answer. And Iruma-kun Season 4, with its higher stakes and continued heart, might be the best entry point yet — as long as they’ve seen the first three seasons, obviously. (Here’s our guide to the best anime for non-anime fans if you need more options for the skeptics in your life.)
Seriously, this show sits perfectly alongside our picks for the best anime to watch with your parents — it’s that clean and that good.

April 2026 Premiere — What We Know About the Release
Iruma-kun Season 4 is confirmed for an April 2026 premiere, slotting into the Spring 2026 anime season. If you want the full picture of everything hitting that season, check out our Spring 2026 Anime Season Complete Guide — it’s stacked.
The April slot puts Iruma-kun Season 4 in a strong position. Spring is historically one of the most competitive anime seasons, but Iruma-kun has never needed to fight for attention through shock value or spectacle — it earns its viewers through quality and keeps them through consistency. An April premiere also means the series runs through Summer 2026, which is solid runway for the arcs on the docket.
Streaming details are still being confirmed at time of writing, but given previous seasons’ availability on Crunchyroll and other platforms, expect the standard simulcast setup. You can catch up on all three previous seasons on Crunchyroll ahead of the Season 4 drop.
The episode count for Iruma-kun Season 4 hasn’t been officially nailed down, but previous seasons ran in the 21–26 episode range. Given the amount of manga content available to adapt, don’t be surprised if Season 4 leans toward the higher end of that range — or if a split-cour announcement follows.
Suzuki Iruma’s Growth: From Terrified Kid to (Accidental) Demon Legend
One of the things that makes Iruma-kun Season 4 so anticipated is how much Suzuki Iruma himself has grown — and how that growth is going to be tested in ways the first three seasons only hinted at.
Iruma started the series as a kid who had learned to disappear. Small, quiet, accommodating — not because he’s weak, but because making himself invisible was the survival strategy that kept him safe. Drop him in a demon school full of beings who can smell weakness and he should, by any logic, be eaten alive.
Instead, the qualities his terrible childhood built in him — hypervigilance, adaptability, an almost preternatural ability to read what people need from him — translate into something the demon world has never seen. He doesn’t just survive Babyls. He thrives. He grows. He collects a found family that would die for him and doesn’t quite understand why.
By the time Iruma-kun Season 4 rolls around, Iruma has ranked up multiple times, survived events that should have destroyed him, manifested genuine connections with demons who operate completely outside his species’ social logic, and begun to genuinely want things for himself — not just to survive, but to belong, to lead, to be worth the faith people keep putting in him.
That last part is what makes Iruma-kun Season 4 emotionally loaded in a way earlier seasons built toward. Iruma now has things to lose. People who depend on him. A version of himself he’s proud of. The stakes of protecting all of that — while still being, technically, a human in a world that would destroy him for it — are the highest they’ve ever been.

The Abnormal Class — Everyone’s Favourite Chaotic Support Squad
You can’t talk about Iruma-kun Season 4 without talking about the Abnormal Class, because they are half the reason this show works as well as it does.
Kalego-sensei’s misfits — the students whose magical aptitudes are so weird, so extreme, or so ungovernable that they couldn’t fit into a normal homeroom — have grown into one of the best ensemble casts in recent shonen. Each of them has a specific thing they do, a specific kind of chaos they bring, and a specific emotional arc that the show takes seriously.
Asmodeus Alice is the most obviously gifted demon in the class and has built his entire identity around Iruma’s perceived greatness. His arc in Iruma-kun Season 4 is about what happens when the person you’ve been worshipping starts needing you to be capable, not just devoted.
Clara Valac is the emotional wildcard. Her powers work on love and desire — she summons things people want. That sounds cute until you realize how deep and dark that gets when the series is willing to go there. Season 4 goes there.
The wider class — Elizabetta, Jazz, Lied, Kamui, Goemon, Agares — each get moments in Iruma-kun Season 4 that the manga crowd has been looking forward to since they were set up. The ranking battles are an ensemble event. This isn’t Iruma solo-carrying. This is a team demonstrating that their particular brand of weird is exactly what the Netherworld needs, even if it doesn’t know it yet.
5 Reasons to Be Hyped for Iruma-kun Season 4 Right Now
- The source material is there. The manga, written by Osamu Nishi, has been running since 2017 and has given the anime plenty of excellent material to work with. The arcs lined up for Iruma-kun Season 4 are fan favourites. The adaptation has been faithful. There’s no reason to expect that changes.
- The animation team knows this world. Four seasons with the same studio means Bandai Namco Pictures has the visual language of Babyls locked in. No soft reboot energy, no jarring style shifts — just clean, consistent animation that knows exactly how to make these characters pop.
- The stakes are finally real. Previous seasons could get away with “will Iruma pass his exam?” as a tension driver. Iruma-kun Season 4 has larger threats circling. The Netherworld’s political dimension becomes impossible to ignore. Things that seemed like background lore start having teeth.
- It rewards rewatchers. Every season of Iruma-kun has planted seeds that pay off later. Going back to Season 1 after watching Iruma-kun Season 4 will be a different experience — you’ll see foreshadowing you missed, character moments that hit differently with context, setup that was invisible the first time through.
- It’s just a great show. This doesn’t need to be complicated. Welcome to Demon School! Iruma-kun is one of the most consistently enjoyable anime of the past five years. Iruma-kun Season 4 is more of that, at a higher level, with more at stake. That’s the whole pitch. It’s enough.
How to Prepare for Iruma-kun Season 4 Before April
You’ve got time. Here’s how to spend it:
- Rewatch Seasons 1–3. All of them. Start to finish. The character work early on pays dividends later and the comedy holds up embarrassingly well.
- Read the manga from Chapter 196 onward. If you want to know what’s coming and you can’t wait, Osamu Nishi’s manga is the source. The chapters that map to Iruma-kun Season 4 start around volume 20.
- Get into the fan community. The Iruma-kun subreddit and Discord servers are active, fun, and notably un-toxic compared to some other fan spaces. Good place to theorize before Iruma-kun Season 4 drops.
- Check out the Spring 2026 season slate. Iruma-kun Season 4 isn’t the only thing worth watching this season — our Spring 2026 complete guide has everything you need to plan your watch schedule.
Final Word: Don’t Sleep on Iruma-kun Season 4
Here’s the thing about Welcome to Demon School! Iruma-kun — it has always been a show that rewards people who actually show up for it. It doesn’t announce itself with explosive hype moments or viral clips. It just builds, episode by episode, a world and a cast of characters that you genuinely care about. And then, once you’re in, it pays off that investment in ways that feel earned rather than manufactured.
Iruma-kun Season 4 is the season where that payoff accelerates. Everything the first three seasons set up — Iruma’s identity, the Babyls ranking system, the political structure of the Netherworld, the Abnormal Class’s potential — comes to a head. The demon school gets serious. Suzuki Iruma gets pushed harder than he ever has been. And the show that has always been quietly excellent gets a chance to announce itself as something genuinely great.
April 2026 can’t come soon enough. If you’re not already counted among the Iruma-kun faithful, there’s still time to catch up. Join us. The demon school has room for one more.
