Let’s talk about Mr. Edogawa for a moment—a character who may not be in the spotlight all the time, but still leaves a strong impression in the Persona 3 anime series. Mr. Edogawa is a teacher at Gekkoukan High School, the same school where the main character and their friends spend much of their days. While he doesn’t appear in every episode, his presence is definitely felt, especially when things get complicated.

Now, Mr. Edogawa isn’t exactly the kind of teacher students run to for casual chats. He’s known for being strict, serious, and, frankly, a bit intimidating. A lot of the students keep their distance because of his no-nonsense attitude. But despite that, there’s no denying his intelligence or skill as an educator—many respect him deeply, even if they’re a little afraid to approach him. Mr. Edogawa clearly values discipline and precision, and that comes through in everything he does.

When it comes to the bigger picture of the story, Mr. Edogawa plays a small yet pivotal role. As the main characters start grappling with the mysterious phenomenon of Personas and the dangerous Shadow creatures lurking around, Mr. Edogawa quietly steps in with crucial insights. He offers guidance—sometimes subtle, sometimes direct—that helps the students understand how to use their abilities more effectively. Without Mr. Edogawa sharing his knowledge at key moments, they might not have stood a chance against the growing threats around them.

Even though he’s not part of the core group fighting on the front lines, Mr. Edogawa’s contributions are far from minor. His sharp analytical mind and ability to piece together complex situations often provide clarity when everything feels chaotic. In fact, you could say that Mr. Edogawa acts as a behind-the-scenes anchor—someone whose wisdom keeps the team grounded. It’s fair to suggest that without Mr. Edogawa’s input, the protagonists might have struggled to reach their ultimate goal: protecting their world from the Shadows and restoring peace to their school and community.

Looking deeper into his personality, Mr. Edogawa seems to fit the INTJ personality type quite well—Introverted, Intuitive, Thinking, Judging. These individuals are usually strategic thinkers, and Mr. Edogawa certainly shows that through his calm, calculated approach to problems. He doesn’t act on emotion; instead, he observes, analyzes, and then moves with purpose. And while he’s not overly social, that fits the INTJ mold too—they often prefer working independently, which Mr. Edogawa clearly does, operating from the shadows rather than seeking attention.

Moreover, INTJs tend to be highly ambitious, and Mr. Edogawa is no exception. He’s driven by a vision—his desire to create what he sees as a “perfect” world. That kind of long-term, idealistic goal is classic INTJ behavior. He’s also somewhat secretive, not quick to reveal his true intentions, which aligns with the typical INTJ trait of skepticism and cautiousness toward others. So yeah, when you think about it, Mr. Edogawa really embodies a lot of what makes the INTJ type unique.

Taking it a step further, Mr. Edogawa also shows strong signs of being an Enneagram Type 5—the Investigator. This type is all about the pursuit of knowledge, independence, and understanding the deeper mechanics of life. Mr. Edogawa spends a lot of time in quiet reflection, observing rather than participating. He’s clearly motivated by intellectual curiosity, always digging deeper into the mysteries surrounding the Persona phenomenon. His reserved nature and need for personal space make sense when viewed through this lens.

The Enneagram Type 5 also tends to feel a deep need to be competent and knowledgeable, and Mr. Edogawa definitely fits that description. He doesn’t just want answers—he needs them. And he wants to arrive at those answers through his own efforts, not by relying too much on others. This independence, combined with his analytical mindset, reinforces the idea that Mr. Edogawa is, at his core, an investigator at heart.

So, wrapping it all up, Mr. Edogawa might not be the loudest or most visible character in Persona 3, but he’s undeniably important. From his role as a disciplined teacher to his behind-the-scenes support during the team’s darkest hours, Mr. Edogawa proves that influence doesn’t always come from being in the front row. Whether you look at him through the lens of MBTI or Enneagram, one thing is clear: Mr. Edogawa is a thinker, a planner, and someone who values knowledge above all else. And honestly, the story wouldn’t be the same without him.
