Nanachi is a character you just can’t forget once you’ve seen her in Made in Abyss. She stands out not just because of her unique look—purple hair, adorable bunny-like ears, and that soft-spoken demeanor—but also because of the depth she brings to the story. While Nanachi isn’t human, she looks mostly human, though technically she’s what’s known as a “hollow”—a being transformed from a person into something part-human, part-animal after exposure to the Abyss. And honestly, that transformation adds so much mystery to who Nanachi really is.

Now, Nanachi plays a major supporting role throughout the series, especially when it comes to helping Riko and Reg on their deep descent into the Abyss. Without Nanachi, things would’ve gone sideways pretty quickly. Her knowledge of the Abyss is unmatched—she knows the creatures, the dangers, the rules of the environment, all of it. That makes her an invaluable guide and ally. But how did she get so knowledgeable? Well, it turns out Nanachi was once part of a group of elite cave raiders, wearing a white whistle, which means they were experienced and skilled. Their past in the Abyss shaped them in ways we’re still learning about, and while a lot of Nanachi’s backstory remains shrouded in mystery, what we do know makes her journey all the more compelling.

At first, Nanachi comes across as quiet, reserved, even a bit distant. They keep to themselves, don’t open up easily, and seem haunted by past trauma. But as the story progresses—and especially through their growing bond with Riko and Reg—Nanachi begins to change. Slowly but surely, their caring side starts to shine through. The warmth, the protectiveness, the genuine love they show for their new friends—it transforms Nanachi into one of the most lovable characters in the series. This emotional growth is central to the show’s message: that connection, compassion, and trust can heal even the deepest wounds.

So, who exactly is Nanachi? Beyond the surface, they’re a complex mix of vulnerability and strength. And when we look at personality types, many fans speculate that Nanachi might be an INFP. Think about it—Nanachi is introverted, deeply empathetic, and guided more by feelings than cold logic. They care intensely about others, often putting themselves at risk just to help. There’s also that imaginative streak—whether it’s tinkering with mechanical devices or getting lost in thought, Nanachi shows strong signs of intuition. Yet, despite being dreamy and sensitive, they’re also incredibly practical when needed, using intelligence and quick thinking to solve life-or-death problems. It’s this balance between idealism and realism that really fits the INFP mold.

Of course, no personality analysis is 100% certain, especially with fictional characters. But based on Nanachi’s actions and emotional responses, the INFP type feels like a strong match. Their gentle nature, emotional depth, and quiet courage all point in that direction. Whether comforting a friend or facing down terrifying creatures of the Abyss, Nanachi consistently acts from a place of empathy and moral conviction.

Then there’s the Enneagram angle. If you’re into that system, Nanachi seems to fit perfectly as a Type Six—the Loyalist. This type thrives on security, loyalty, and preparedness, often anticipating danger before it happens. Sound familiar? Nanachi is always on high alert in the Abyss, constantly assessing risks and planning for worst-case scenarios. That hyper-vigilance isn’t paranoia; it’s born from experience and a deep desire to keep their friends safe. Their loyalty, especially toward Mitty, shows just how much they value trust and commitment in relationships.

Even Nanachi’s hesitation and self-doubt align with Type Six traits. They don’t rush into decisions or trust easily—Reg, for instance, had to prove himself over time before Nanachi fully accepted him. But once that trust is earned? It’s unshakable. That journey from suspicion to deep companionship highlights the core of what makes Nanachi so relatable and human, despite not being fully human at all.

In the end, Nanachi is more than just a guide or side character. They’re a symbol of resilience, healing, and the power of connection. From a lonely, broken soul to a devoted friend and protector, Nanachi’s evolution is one of the heartbeats of Made in Abyss. And whether you’re analyzing them through MBTI, Enneagram, or just your own emotional response, one thing’s clear: Nanachi leaves a lasting impact. So yeah, if you ask any fan about Nanachi, you’ll probably hear the same thing—they’re unforgettable.
