I’ve watched Welcome to Demon School! Iruma-kun five times now, and I’ve even re-read the manga once. I don’t usually do that with most series, so I think that alone says something. But what’s more interesting is how my experience with this anime changed over time. The first time I watched it, I was just there for the story. I wanted to see what would happen next, how Iruma would survive in the demon world, how long he could keep his secret, and how everything would play out. It felt like a fun, light anime with good comedy and a unique setting. I enjoyed it, but I didn’t think too deeply about it.

But after rewatching it multiple times, I realised I was completely missing what actually makes this series special.

For me, Iruma-kun is what I would call a “comfort world.” It’s not just a comfort anime; it’s a world you can sit in and feel good about. There’s no unnecessary darkness, no forced tragedy, and no constant stress. Instead, it focuses on growth, friendship, and small moments that just make you smile. And somehow, despite being so light in tone, it never feels boring or empty. That’s something I’ve come to appreciate a lot more after rewatching it.

One of the biggest changes in how I experienced the series came from shifting my focus. The first time, I was only paying attention to the main plot. But once I already knew what was going to happen, I started noticing everything else. Background characters reacting to situations in their own way, small expressions during conversations, and little details that I had completely ignored before. Even the sukima segments, which I barely paid attention to in my first watch, became something I actually looked forward to. They add so much personality and humor to the characters, and skipping them now feels like missing part of the experience.

This is where the series really started to stand out to me. It’s not just telling a story, it’s building a world that feels alive. The characters don’t exist only when the plot needs them. It feels like they’re always doing something, always reacting, always present in the background. That’s what makes Babyls feel like a real place instead of just a setting.

The characters themselves are a huge reason why I enjoy this series so much. Iruma is such a simple character on the surface, but the more you watch him, the more you realize how well he’s written. He’s kind, but not in a naive or unrealistic way. His kindness comes from his past, from everything he went through, and it feels genuine. What I like the most is that he grows without losing that part of himself. He becomes more confident, more capable, and more aware of his surroundings, but he never turns into a completely different person. That balance is hard to maintain, but the series does it really well.

Azz is another character who grew on me a lot. At first, his loyalty felt exaggerated and played mostly for comedy. But over time, it started to feel more meaningful. His belief in Iruma isn’t blind. It develops as he sees more of who Iruma really is. There’s a moment where he openly says that Iruma will become the Demon King, and instead of it feeling like a joke, it actually feels like a genuine belief. That moment hit differently because it showed how much his perspective had changed.

Clara is probably the most chaotic character in the series, but she’s also one of the most fun to watch. What I like about her is that she never feels forced. She’s unpredictable, but in a natural way. And even though she’s mostly there for humor, there are moments where you can see her emotional side, which adds more depth to her character.

What surprised me the most is that even side characters feel important. There aren’t many characters that I dislike in this series, which is rare. Everyone has their own personality, their own role, and their own moments to shine. It makes the world feel more complete.

As the story progresses, it slowly starts to expand. What begins as a simple school setting starts introducing more elements like rankings, politics, and the structure of the demon world. But what I appreciate is that it never loses its original vibe. It doesn’t suddenly become dark or overly serious just to raise the stakes. Instead, it grows naturally while maintaining the same tone.

There are also subtle layers in the story that you only start noticing after paying closer attention. Iruma’s identity is an obvious one, but it’s handled in a very controlled way. Not everyone knows, and the people who do react differently. Then there are characters like Sullivan, whose intentions are still not fully clear. It makes you wonder why he chose Iruma specifically, because it definitely doesn’t feel random.

And then there’s Amu. The more I think about her interactions with Iruma, the more it feels like she knows something. She’s way too perceptive, and Iruma stands out too much for her to miss it. What makes it interesting is that she never questions him. She just accepts him. Even in their first interaction, she reads him quickly and doesn’t show any confusion or suspicion. That kind of reaction feels intentional. It doesn’t feel like she’s unaware, it feels like she understands and chooses not to say anything. Moments like that add another layer to the story and make it more engaging.

One thing I’ve realized is that I don’t rewatch this series just for the story anymore. I rewatch it because of how it makes me feel. It’s relaxing, it’s enjoyable, and it’s something I can come back to without getting tired of it. That’s not something I can say about most anime.

There’s also something about the way the series handles growth that I really like. It’s not about sudden power-ups or dramatic changes. It’s about gradual development. Characters grow over time, relationships evolve, and everything feels earned. That kind of pacing makes the story more satisfying in the long run.

Another thing worth mentioning is how consistent the series is. It knows what it wants to be and sticks to it. It doesn’t try to chase trends or force unnecessary elements into the story. It focuses on its strengths and builds on them. That’s probably why it feels so stable and enjoyable throughout.

If I had to point out something that makes this series stand out compared to others, it would be its ability to create a world you actually want to be in. A lot of anime have interesting worlds, but not many feel comfortable. Iruma-kun manages to do both. It has a unique setting, but it also feels welcoming.

At this point, I don’t even think of it as just another anime I watched. It’s something I keep coming back to. And every time I do, I notice something new or appreciate something I didn’t before. That kind of experience is rare.

In the end, Welcome to Demon School! Iruma-kun might not be the most intense or complex series out there, but it does something that matters more to me. It creates a space where I can relax, enjoy the characters, and just have a good time. And honestly, that’s enough.

And yeah, I’ll probably end up watching it again.
