Does Iruma become a demon in Season 4 of Welcome to Demon School! Iruma-kun?
Fans of Welcome to Demon School! Iruma-kun are buzzing with anticipation as Season 4 approaches in April 2026. After three seasons of laughter, chaos, and heartwarming moments, the big question on everyone’s mind is: Will Iruma finally become a demon? If you’re like me, a die-hard fan who re-reads the manga and binge-watches every episode multiple times, the answer might surprise you.
Iruma’s Human Nature Remains Intact
Despite the hype and the increasingly complex powers he shows, Iruma remains 100% human. Sure, his visual transformations like the “Evil Cycle” persona—affectionately dubbed Irumean by the fanbase—make him look and act like a high-ranking demon. But these changes are psychological and tactical, not biological. Season 4 will see him tackling the Music Festival Arc and the Evidol Games, where he relies on cunning, charisma, and the Ring of Gluttony to compete—not a demonic body.
It’s important to note:
- Mana Usage: Iruma’s high-level magic comes from Sullivan’s stored mana in the Ring, not his own demonic lineage.
- Prophecy Confusion: A prophecy hints that the next Demon King will dominate the demon world. Iruma is a candidate, but there’s no requirement for him to become a demon to fulfill it.
Why Fans Think Iruma Might Be a Demon
Reddit threads and YouTube theory videos are buzzing with speculation. Here’s a breakdown of the top fan theories:
- Reincarnation of Demon King Delkira
- Evidence: Iruma’s silhouette resembles Delkira, and the Ring of Gluttony reacts uniquely to him.
- Twist: Delkira may have chosen to reincarnate as a human to experience kindness before ruling.
- Hybrid or Half-Demon Theory
- Some believe Iruma’s human parents may not be his biological ones—or that one parent was secretly a demon.
- This would explain his resilience in the Netherworld and Sullivan’s eagerness to “buy” him.
- Fusion with Alikred (Ali-san)
- As Iruma grows stronger, Alikred evolves and becomes increasingly “inseparable” from him.
- This could make Iruma a demon in essence, even if he remains human physically.
Honestly, as a fan, I love this last theory. It’s the perfect mix of suspense and emotional depth—Iruma may never physically transform, but the bond with Alikred gives him a demonic aura that feels just as powerful.
Season 4: What to Expect
Season 4 is shaping up to be one of the most colorful, music-filled seasons yet. Here’s a sneak peek of what’s coming:
| Arc | Key Details | Why It Matters |
|---|---|---|
| Music Festival Arc | Abnormal Class must reach Rank 4 (Daleth) to keep their classroom. Introduces Purson Soi, the 13th student who’s been invisible until now. | Shows Iruma using intelligence, charm, and teamwork rather than demonic strength. |
| Evidol Games | Features Iruma in his cross-dressing “Irumi” persona for Demon Idol competition. | Demonstrates his growing skill at blending into demon society without losing his human identity. |
Fans shouldn’t expect a literal transformation this season. Instead, we’ll see Iruma mastering his human strengths to achieve feats that dazzle even the most powerful demons.
The Real Strength: Being Human
What makes Iruma fascinating—and why I love this series—is that he doesn’t need to become a demon to rule. His kindness, quick thinking, and courage allow him to win over characters like Asmodeus and Sabnock. Season 4 will lean into this core theme: it’s Iruma’s human heart that makes him a true force in the demon world.
A key plot twist on the horizon involves villains like Kirio and the Six Fingers trying to expose him as a human. This will create chaos in the demon world and put Iruma’s human identity to the ultimate test. Fans like me are dying to see how he will handle it—and knowing Iruma, it will be clever, emotional, and hilariously awkward.
Conclusion: Human Heart, Demon Throne
So, will Iruma become a demon in Season 4? Not physically. But in terms of influence, strategy, and power, he’s already walking the path of a demon king. Season 4 promises epic battles, heartwarming friendships, and plenty of comedic chaos—all while Iruma proves that sometimes being human is the most powerful “demon” trait of all.
For fans who have followed every misadventure since Season 1, this season isn’t just about transformation—it’s about Iruma embracing who he is and showing that the strongest leaders don’t need to change their nature—they just need to trust their hearts.
