Eris is one of the standout characters in the anime series Tsukimichi: Moonlit Fantasy, which is adapted from the light novel of the same name by Kei Azumi. The show first aired on July 7, 2021, and follows the journey of Misumi Makoto, a high school student suddenly summoned to a magical world as a hero. Along the way, he crosses paths with Eris—daughter of the Dragon God—who quickly becomes one of his most trusted allies.

At first glance, Eris comes across as calm, composed, and even a bit intimidating. She’s an incredibly skilled warrior, wielding a powerful magic sword that strikes fear into her enemies. But as the story unfolds, viewers begin to see a different side of her. Beneath that cool exterior, Eris is actually warm-hearted and deeply compassionate. Her loyalty to those she cares about, especially Makoto, runs incredibly deep, and she isn’t afraid to put herself on the line to protect them. So while Eris may seem distant at first, her actions consistently show just how much she values her companions.

Of course, it’s hard not to notice Eris’s striking appearance—something that other characters comment on frequently throughout the series. With her long black hair, vivid red eyes, and bold fashion sense that highlights her figure, she definitely turns heads. But here’s the thing: Eris is so much more than just her looks. Sure, she’s beautiful, but what really defines her are her strength, her courage, and the emotional growth she experiences over time. Eris evolves in meaningful ways, revealing layers that make her far more than a simple archetype.

As the series progresses, Eris continues to stand out—not only as a fighter but as a complex individual with depth and purpose. She brings a unique energy to Tsukimichi: Moonlit Fantasy, balancing fierce independence with genuine care for others. And honestly, it’s fascinating to watch her journey unfold. There’s always something new to learn about Eris, whether it’s her past, her motivations, or the way she interacts with the world around her.

Now, when we look at Eris through the lens of personality typing, there’s a strong case to be made that she fits the ESTP profile—Extroverted, Sensing, Thinking, Perceiving. These types are often action-oriented, love challenges, and thrive in high-pressure situations—all of which describe Eris perfectly. Think about it: she dives headfirst into battle, trusts her instincts, and lives very much in the moment. That impulsive, fearless attitude? Classic ESTP behavior. Plus, she values competence above all else, which explains why she respects Makoto so much—he’s smart, capable, and earns her admiration through his actions.

And let’s not forget—Eris is confident, sometimes to the point where others might see her as domineering. But that assertiveness also comes from a place of protection. She wants control because she believes it’s the best way to keep her friends safe. That same intensity fuels her loyalty, making her someone you’d definitely want on your side in a tough situation.

From an Enneagram perspective, Eris lines up closely with Type 8—the Challenger. This type is all about strength, autonomy, and taking charge. Eris doesn’t back down from confrontation, speaks her mind freely, and refuses to be controlled by anyone—even authority figures. She leads by example and expects the same level of honesty and courage from others. While her strong will can occasionally lead to clashes, especially when others challenge her decisions, it’s clear that her intentions come from a protective instinct rather than a need for power alone.

All in all, Eris is a dynamic and multi-dimensional character whose presence enriches the world of Tsukimichi: Moonlit Fantasy. Whether it’s her combat prowess, her evolving emotional depth, or her bold personality, Eris leaves a lasting impression. And as the story continues, there’s no doubt fans will keep discovering new sides to her—because Eris isn’t just a warrior, or a beauty, or a loyal companion. She’s all of those things and more.
