Masamichi Yaga, often referred to as Principal Yaga, plays a significant supporting role in the widely acclaimed anime Jujutsu Kaisen. As the head of Tokyo Metropolitan Curse Technical College—the central setting for much of the series—Masamichi Yaga is deeply involved in shaping the next generation of Jujutsu sorcerers. His leadership isn’t just administrative; it’s personal. He dedicates himself to training and guiding young fighters so they can stand against curses and protect innocent lives.

Now, while his position carries a lot of weight, Masamichi Yaga never lets authority change who he is. In fact, one of the things that stands out most about him is how grounded and kind he remains. Whether it’s offering thoughtful advice or simply being present during tough moments, Masamichi Yaga consistently shows empathy toward his students. And honestly, that’s probably why both faculty and peers hold him in such high regard. He’s not just a leader—he’s someone others can trust, especially when danger strikes. More than once, Masamichi Yaga has put himself on the line to shield others, proving just how selfless he truly is.

But behind that calm exterior lies a painful history. It turns out, Masamichi Yaga suffered a devastating loss when his wife and daughter were killed in a curse attack. That tragedy didn’t break him—it transformed him. Instead of retreating, he channeled his grief into purpose, becoming a Jujutsu sorcerer and later a teacher to ensure no other family would have to endure what he did. This past gives him a unique understanding of pain, which makes his mentorship all the more meaningful. When Masamichi Yaga tells his students to grow stronger, it’s not just about power—it’s about resilience, responsibility, and protecting those who can’t protect themselves.

In the grand narrative of Jujutsu Kaisen, Masamichi Yaga stands out as both a moral compass and a quiet pillar of strength. Viewers tend to gravitate toward characters like him—not because he’s flashy, but because he’s real. His wisdom, integrity, and deep sense of duty make Masamichi Yaga a role model, both within the story and for the audience watching it unfold. He may not always be at the front lines, but his influence is felt everywhere.

When we look at Masamichi Yaga through the lens of personality typing, there’s a strong case for him being an ISTJ—Introverted, Sensing, Thinking, Judging. These individuals are known for their practicality, discipline, and reliability, all traits that fit Masamichi Yaga like a glove. He approaches problems logically, weighs consequences carefully, and rarely acts on impulse. You’ll notice he doesn’t shout or seek attention; instead, Masamichi Yaga observes, assesses, and acts with precision. His respect for tradition and structure is evident in how seriously he upholds the rules of the Jujutsu world. Even his teaching style reflects this: strict, consistent, and rooted in proven methods.

And sure, Masamichi Yaga might come off as reserved—or even a bit distant—to some. But that quiet nature doesn’t mean he lacks care. On the contrary, ISTJs like Masamichi Yaga often express loyalty through action rather than words. When push comes to shove, he’s the first to step in front of danger for his students. That kind of devotion speaks volumes, even without dramatic speeches.

Then there’s the Enneagram angle. If we consider deeper motivations, Masamichi Yaga fits perfectly as a Type 1: the Reformer, also known as the Perfectionist. This type is driven by a desire to do what’s right, to uphold justice, and to eliminate flaws—both in themselves and in the world around them. And honestly, does that not describe Masamichi Yaga to a T? His entire life seems built around maintaining order, enforcing ethical standards, and striving for a better future. He holds himself accountable in ways few others do, constantly pushing to live up to his own ideals.

Of course, this pursuit of perfection has its downsides. At times, Masamichi Yaga can seem rigid, even overly critical. His black-and-white view of morality sometimes makes compromise difficult, leading to tension with others who see shades of gray. But even then, you can’t deny his intentions. There’s no selfishness in Masamichi Yaga—only a genuine desire to protect and improve.

So, putting it all together, Masamichi Yaga emerges as a layered, inspiring figure in Jujutsu Kaisen. Whether you’re analyzing him psychologically or simply appreciating his role in the story, one thing is clear: Masamichi Yaga embodies the quiet heroism of doing what’s right, even when no one’s watching. His blend of compassion, discipline, and unwavering principle cements him as one of the most respected—and quietly impactful—characters in the series. And frankly, the world could use more people like Masamichi Yaga.
