Natsumi Kurobe is definitely one of the standout characters in the romantic comedy anime My Senpai Is Annoying, also known as Senpai ga Uzai Kouhai no Hanashi. As a central figure in the story, Natsumi brings both charm and depth to the series. She’s a smart, capable, and hard-working woman who shares the same workplace—an advertising agency—with her senpai, Harumi Takeda. From the very beginning, it’s clear that Natsumi takes her job seriously, showing off her intelligence, independence, and strong sense of responsibility. While many people look up to her for her professionalism and dedication, it’s really her evolving relationship with Takeda that makes Natsumi such an interesting and endearing character.

On the surface, Natsumi comes across as serious, composed, and maybe even a little reserved. She has that quiet intensity that makes her seem unapproachable at times. But when she’s around Takeda—despite constantly rolling her eyes at his antics—there’s a softer, more playful side that starts to show. Sure, she finds him annoying more often than not, calling out his childish behavior and lack of focus, but if you pay close attention, there are subtle hints that she actually cares for him in a deeper way. In fact, Natsumi secretly harbors romantic feelings for him, though she keeps them well hidden. Why? Well, like many of us, she’s afraid of rejection. The thought of confessing and not having her feelings returned is just too risky, so she keeps things professional—on the outside, at least.

One thing you quickly notice about Natsumi Kurobe is how much she overthinks. Seriously, she analyzes every interaction, every comment, every glance—especially when it involves Takeda. It’s almost like her mind never shuts off. But this tendency to overanalyze isn’t just limited to her personal life; it actually serves her well at work. She’s extremely detail-oriented, observant, and perceptive, which makes her a valuable asset in the fast-paced world of advertising. When she gets pulled into Takeda’s projects—usually because he can’t handle them on his own—her creativity and problem-solving skills really shine. She doesn’t just follow instructions; she thinks ahead, anticipates problems, and delivers results. That’s part of what makes her so respected in the office.

All in all, Natsumi Kurobe adds a lot of emotional and intellectual depth to My Senpai Is Annoying. Her journey—balancing career ambitions, personal growth, and complicated feelings for her senpai—is something a lot of viewers can connect with. Whether she’s quietly supporting Takeda or pushing herself to meet tight deadlines, Natsumi feels real, relatable, and refreshingly human. And honestly, that’s why so many fans have grown to love her.

Now, when it comes to personality typing, Natsumi Kurobe fits quite neatly into the ESTJ category—Extraverted, Sensing, Thinking, Judging. Now, don’t let the “extraverted” part fool you; she’s not loud or overly social, but she does engage confidently in structured environments like the workplace. What really defines her as an ESTJ is her incredible work ethic, her love for organization, and her no-nonsense attitude. She likes things done right, on time, and with minimal drama. You won’t catch her daydreaming or getting lost in abstract theories—Natsumi is all about practicality, efficiency, and tangible results.

She’s also pretty direct in how she communicates. If something needs to be said, Natsumi says it—plain and simple. Some might see her as blunt or even a bit harsh, but that’s just how she operates. She values honesty and clarity, and beating around the bush? Not her style. This straightforwardness can sometimes clash with Takeda’s more carefree approach, but it also balances him out in unexpected ways.

When we look at her through the lens of the Enneagram, Natsumi Kurobe strongly aligns with Type 3: The Achiever. Ambitious, goal-driven, and highly motivated, she’s always striving to do better, be better. Recognition matters to her—not in a vain way, but because it validates her hard work and competence. She wants to succeed on her own terms, and she’s willing to put in the hours to get there. There’s a perfectionist streak in her too, and a real fear of failure that pushes her to double-check everything and prepare for every possible outcome.

That said, there are moments—small but telling—where we see glimpses of Type 7: The Enthusiast. Like when she dives headfirst into a cosplay project or takes a break to game with colleagues. These instances show that beneath her disciplined exterior, Natsumi enjoys fun, spontaneity, and new experiences. But overall, her core motivation revolves around achievement, excellence, and proving her worth—hallmarks of a Type 3.

So, while personality types aren’t set in stone and people can display traits from multiple categories, Natsumi Kurobe’s consistent drive, discipline, and desire to excel point most clearly toward Type 3. Combined with her ESTJ tendencies, this makes her a well-rounded, dynamic character whose strengths and vulnerabilities feel authentic.

In the end, whether you’re drawn to her professionalism, her quiet affection for Takeda, or her inner struggles with self-doubt and romance, Natsumi Kurobe stands out as a truly memorable character. And honestly, it’s hard not to root for her—because deep down, she’s someone we all see a little bit of ourselves in. Natsumi Kurobe, without a doubt, is one of the heartbeats of My Senpai Is Annoying.
