Welcome to Demon School! Iruma-kun Heartbreaker Arc: Results, Spoilers, and Shocking Aftermath
The Heartbreaker Arc in Welcome to Demon School! Iruma-kun (chapters 223–266) is easily one of the most intense and emotionally charged arcs in the entire series so far. As someone who has followed the manga for years, I honestly felt like this storyline changed the tone of the series in a big way.
Up until this point, the Misfit Class had been on an incredible winning streak. They dominated the Harvest Festival, stunned everyone during the Music Festival, and slowly built a reputation as the most unpredictable and talented group in the academy. But the Heartbreaker Exam showed something important: talent alone isn’t enough in the demon world.
This arc felt like the story’s first true reality check for the characters we’ve grown attached to.
Why the Heartbreaker Exam Was Created
The Heartbreaker Exam was introduced by Naberius Kalego, the strict but secretly supportive homeroom teacher of the Misfit Class.
After watching his students rise to fame too quickly, Kalego realized something dangerous was happening: they were becoming overconfident.
Instead of another straightforward promotion test, the teachers designed a brutal survival-style exam.
The rules were deceptively simple:
- Second-year students from the Misfit Class were paired with first-year students.
- Each pair had two balloons representing their “hearts.”
- Teachers acted as hunters trying to pop those balloons.
- If both balloons were destroyed, the team failed.
At first glance it sounded like a game. But once the exam started, it became clear the teachers were not holding back.

The Exam Quickly Turns Brutal
One of the reasons this arc stands out is how chaotic it becomes.
The teachers hunting the students weren’t random instructors—they were top-tier demons with incredible abilities. Watching the Misfits try to survive against them felt like a completely different genre compared to earlier school arcs.
For many characters, this was the first time they truly realized the gap between students and experienced demons.
Even normally confident characters started struggling.
The exam also introduced a huge psychological element: protecting yourself was hard enough, but protecting a younger first-year partner made everything far more stressful.
The Students Who Managed to Survive
Despite the overwhelming pressure, a few members of the Misfit Class managed to keep at least one balloon intact.
Two standout performers were:
- Asmodeus Alice
- Sabnock Sabro
Asmodeus especially had a major moment in the arc. He demonstrated his evolved blue flames, showing how much he had grown as both a fighter and a leader.
Sabnock also survived the exam, but his victory didn’t feel like a celebration. His confrontation with one of the arc’s villains overshadowed the achievement and hinted at much darker developments ahead.
Here’s a simplified overview of some outcomes:
| Character | Result | Notable Moment |
|---|---|---|
| Asmodeus Alice | Passed | Revealed powerful blue flames |
| Sabnock Sabro | Passed | Encountered a dangerous traitor |
| Iruma Suzuki | Failed | Targeted during the chaos |
| Several Misfit members | Failed | Overwhelmed by teacher hunters |
Even for those who technically succeeded, the emotional toll of the exam was heavy.
The Shocking Traitor Reveal
Halfway through the arc, the story takes a dramatic turn.
One of the newly hired teachers, Atori, reveals himself to be a member of the criminal organization known as the Six Fingers.
Instead of following the rules of the exam, Atori launches a reckless attack with a clear objective:
Capture Iruma.
The moment he dropped the teacher disguise, the arc suddenly shifted from a school competition into a full-blown thriller.
Iruma became the center of a dangerous situation far beyond the scope of a simple exam.
Shiida’s Unexpected Choice
Another fascinating character in this arc is Shiida.
At first, she also appeared to be aligned with the Six Fingers. However, when the situation spiraled out of control, she did something completely unexpected.
She protected Iruma instead of helping Atori.
This moment sparked countless theories among fans. Some readers believe Shiida might eventually:
- Become an ally to Iruma
- Leave the Six Fingers permanently
- Even act as a mentor figure later in the story
Her motivations are still somewhat mysterious, which only makes her character more intriguing.
Iruma’s Defeat – A Controversial Moment
The biggest surprise for many readers was the outcome for the main character.
Iruma Suzuki—despite his incredible survival instincts and evasive abilities—lost the exam.
His team’s balloons were destroyed during the chaos, eliminating them from the promotion test.
Among fans, this moment sparked a lot of debate.
Some readers felt the loss was forced in order to slow down Iruma’s progression. After all, he had been succeeding at almost every major challenge until this point.
Others argued the opposite: this failure was necessary for character development.
Personally, I lean toward the second interpretation. Seeing Iruma lose made the story feel more grounded. If he’s truly meant to become the future Demon King, he needs to experience failure too.
A Suspicious Connection Behind the Scenes
One of the most intriguing reveals in the arc involves Naberius Narnia.
Narnia, the older brother of Kalego, works as the Chief of Border Patrol. It turns out that both Atori and Shiida were recommended for their teaching positions through him.
That revelation immediately raised red flags.
Is Narnia secretly connected to the Six Fingers?
Or is he unknowingly being manipulated?
The manga hasn’t fully answered these questions yet, but it clearly planted seeds for future conflict.
The Aftermath: A Darker Direction for the Story
When the Heartbreaker Exam finally ends, the academy is left with more questions than answers.
Security at the school suddenly looks fragile, and the students now understand that real enemies exist outside the classroom.
For the Misfit Class, the arc leaves a lasting impact:
- Many students failed to earn rank promotions.
- Their confidence took a major hit.
- They realized how dangerous the demon world truly is.
The story begins shifting toward more serious themes, including preparation for a potential conflict involving the demon leader Baal.
Training becomes more intense, and several characters start working on mastering their Wicked Phase and advanced magic techniques.
Why This Arc Matters for the Future of the Series
Looking back, the Heartbreaker Arc feels like a turning point for Welcome to Demon School! Iruma-kun.
Earlier arcs focused heavily on school events and character comedy. But this storyline proves the series is capable of something much deeper.
It shows that:
- Fame can make you a target
- Power attracts dangerous enemies
- And even the most talented students can still fail
For Iruma, this arc reinforces an important truth: becoming the Demon King isn’t just about kindness or luck.
It’s about learning to protect the people who rely on you, even when the world becomes far more dangerous than you expected.
And if this arc is any indication, the challenges ahead for the Misfit Class are only going to get tougher.
