Let’s talk about Mr. Osomatsu—a beloved anime series that first hit the screens in 2015, bringing a fresh twist to the classic manga Osomatsu-kun, which originally debuted way back in 1962. The show centers around the hilarious and chaotic lives of six identical brothers from the Matsuno family, each with their own distinct quirks. Among them, one character really stands out: Matsuno Karamatsu.

Now, when we think about Mr. Osomatsu and its colorful cast, it’s hard not to mention Matsuno Karamatsu—affectionately called Kara-Matsu by fans—who plays a central role in the series. He’s the second-oldest of the sextuplets and, without a doubt, the most stylish. You’ll often catch him decked out in bold, over-the-top outfits, whether he’s just lounging at home or stepping out for groceries. His fashion sense is next-level, and honestly, it’s one of the things that makes Mr. Osomatsu so fun to watch.

At first glance, you might think Karamatsu is all about vanity and appearances—and sure, he does love looking good—but there’s more beneath the surface. Underneath that flashy exterior is a genuinely kind and sensitive guy. While his brothers may roll their eyes at his dramatics, Matsuno Karamatsu always shows up when it matters, proving he’s got heart. In fact, he’s often the one quietly supporting his siblings during tough times, even if he doesn’t get much credit for it.

One thing you can’t ignore about Matsuno Karamatsu is his passion for music. Singing is basically his life. He’s constantly trying to perform, belting out tunes with full drama and flair, though, let’s be honest, his brothers usually find it more annoying than impressive. Still, rejection doesn’t stop him. No matter how many times they groan or shut their doors, Karamatsu keeps practicing—often in private, dreaming of the day he’ll become a top idol. That kind of determination? It’s actually pretty admirable.

So, when you put it all together, Matsuno Karamatsu adds a unique flavor to Mr. Osomatsu. His flamboyant style, musical dreams, and big heart make him a standout character. He’s not just comic relief—he brings emotional depth and charm, which is probably why so many fans have grown attached to him. In a show full of absurd humor, Karamatsu manages to stay both entertaining and endearing.

Digging a little deeper into his personality, Matsuno Karamatsu seems to fit the INFP profile—introverted, intuitive, feeling, perceiving. If you’re familiar with personality types, you’ll know INFPs are often dreamers, idealists who value authenticity. And that’s exactly what Karamatsu embodies. His bold fashion choices aren’t just for show—they’re a form of self-expression, a way to say, “This is who I am.” He doesn’t care about fitting in; he wants to stand out, on his own terms.

He’s also deeply empathetic. Even when he’s wrapped up in his own world, Matsuno Karamatsu notices when someone’s hurting. He avoids conflict not because he’s weak, but because he values harmony and emotional connection. That sensitivity ties right into the “feeling” aspect of his personality type. And let’s not forget how dreamy and spacey he can seem—lost in thought, imagining grand performances or poetic moments. That’s the intuition part shining through, giving him creative vision, even if it sometimes makes him appear distracted.

Then there’s the Enneagram angle. When we look at Matsuno Karamatsu through that lens, he strongly aligns with Type 4—the Individualist. At 18 years old, he’s navigating that delicate balance between wanting to be seen and feared being misunderstood. His entire identity in Mr. Osomatsu revolves around being different, special, unique. Whether it’s his wardrobe or his singing ambitions, everything he does screams, “I’m not like everyone else!”

But being a Type 4 isn’t always easy. There are moments when Karamatsu retreats into himself, overwhelmed by melancholy or feelings of inadequacy—especially when he compares himself to others, like his older brother who naturally draws attention. That jealousy? It’s not mean-spirited; it comes from a deep desire to be appreciated for who he truly is. He craves emotional intimacy and validation, yet struggles with vulnerability, swinging between seeking the spotlight and isolating himself in quiet sorrow.

All in all, Matsuno Karamatsu from Mr. Osomatsu is far more than just the flashy, singing brother. He’s a complex character shaped by his need for authenticity, emotional depth, and creative expression. Whether you’re drawn to his fashion, his voice, or his heartfelt moments, one thing’s for sure—Matsuno Karamatsu leaves a lasting impression. And in a show as wild and wacky as Mr. Osomatsu, that’s no small feat.
