Nana Chigusa is one of the central figures in the anime series Nana to Kaoru, and honestly, she’s a character that really stands out. She’s not just another pretty face—Nana Chigusa is intelligent, composed, and admired by many of her male classmates for her beauty and grace. But beneath that seemingly perfect exterior, there’s more to Nana than meets the eye. In fact, she carries a deep secret, something she carefully hides from everyone around her, including those closest to her.

The story primarily revolves around Nana Chigusa’s evolving relationship with Kaoru, the titular character and her childhood friend. He lives nearby, and though he’s quiet and introverted, Kaoru has strong feelings for Nana. The thing is, he finds it incredibly hard to express them because of his shy nature. Despite their contrasting personalities—Nana being more outwardly confident while Kaoru tends to stay in the background—the two share a special connection built on trust, understanding, and genuine care for each other.

When you take a closer look at Nana Chigusa, you start to see how layered her personality truly is. On the surface, she appears strong, independent, and capable of handling almost anything life throws at her. But like anyone else, Nana has moments of vulnerability and self-doubt. During these times, she often leans on Kaoru, showing that even someone as poised as Nana Chigusa needs support now and then. As the series progresses, viewers get to witness her personal growth—how she gradually faces her fears, deals with emotional challenges, and slowly learns to open up to others.

Honestly, Nana Chigusa is such a compelling character. Her journey through issues of identity, love, and self-acceptance resonates with a lot of people. Whether you’re into anime or just enjoy well-written characters, Nana Chigusa definitely leaves an impression. The way she interacts with Kaoru feels both heartwarming and real—it’s not just about romance, but about mutual respect and emotional intimacy.

Now, if we dive into personality typology, Nana Chigusa seems to fit the ISTJ profile quite well—Introverted, Sensing, Thinking, Judging. People with this MBTI type are usually practical, dependable, and value structure and responsibility, which lines up perfectly with what we see in Nana Chigusa. She’s consistently shown as a diligent student who follows rules and approaches life in a logical, organized manner. Nana Chigusa doesn’t do things impulsively; she plans, evaluates, and acts with purpose.

Moreover, Nana Chigusa tends to keep to herself, which reflects her introverted side. Socializing isn’t something she seeks out unless necessary. Instead, she focuses on her duties—whether it’s schoolwork, family obligations, or supporting Kaoru. That sense of responsibility? It’s a hallmark of her Judging trait. And let’s not forget: Nana Chigusa holds herself to very high standards. When others don’t meet those expectations, she can come across as critical—even harsh at times.

Her thinking preference also plays a big role. Nana Chigusa relies heavily on logic and analysis when making decisions. This makes her excellent at solving problems, but it can also make her seem emotionally detached or overly rigid. While her approach is efficient, it sometimes comes at the cost of empathy. There are moments when Nana Chigusa struggles to connect with others on an emotional level, not because she doesn’t care, but because her natural tendency is to prioritize reason over feelings.

Looking at the Enneagram, Nana Chigusa most likely falls under Type 8—the Challenger. These individuals are driven by a need for control and autonomy, and they deeply fear being controlled or taken advantage of. Nana Chigusa’s assertiveness and strong will are clear signs of this type. She speaks her mind, stands up for her beliefs, and isn’t afraid to challenge norms when she feels it’s necessary. At the same time, she shows a protective side, especially toward Kaoru, which adds depth to her character.

Still, this desire for control can lead Nana Chigusa to act impulsively or overlook how her actions affect others. Her fear of vulnerability often causes her to guard her emotions tightly, making it difficult for her to form deeper emotional bonds. She keeps people at a distance, not out of coldness, but as a defense mechanism.

In the end, Nana Chigusa is a multifaceted character whose personality can be understood through frameworks like MBTI and Enneagram. Whether viewed as an ISTJ or a Type 8, her traits paint a picture of someone who values strength, independence, and integrity. Of course, these models aren’t set in stone—they’re tools to help us understand behavior, not label or limit people. But one thing’s for sure: Nana Chigusa remains a memorable and thought-provoking character throughout Nana to Kaoru.
