Justin Law is a major character in the anime series Soul Eater, which is based on the manga created by Atsushi Ohkubo. As a Meister—essentially a weapon specialist—Justin Law plays a significant role throughout the story, beginning as a loyal servant of Lord Death and a member of the elite Death Scythes, the personal guard entrusted with protecting the balance between life and death. Over time, however, his path takes a complicated turn when he becomes entangled with Arachnophobia, a dangerous organization bent on overthrowing the established order.

When we first meet Justin Law, he comes across as disciplined, reserved, and deeply committed to his duties. He’s often seen with his eyes closed and maintaining a calm, almost emotionless expression, which only adds to his mysterious aura. Despite his quiet demeanor, Justin Law is far from weak—he’s an incredibly capable fighter who wields a versatile staff that can morph into multiple blades or stretch out for long-range combat, making him a formidable opponent on the battlefield.

As the series progresses, Justin Law’s true intentions become harder to pin down. While he starts off as a staunch believer in Lord Death’s mission, his growing association with Arachnophobia raises questions about where his loyalties truly lie. Is he infiltrating the group from within? Or has he genuinely shifted sides? The show never gives a clear answer, leaving fans to debate Justin Law’s motivations long after the final episode. This ambiguity is part of what makes Justin Law such a compelling figure in Soul Eater.

Even though his ultimate fate remains uncertain, Justin Law leaves a lasting impression. His calm intensity, combat prowess, and moral complexity set him apart from many other characters in the series. He’s not just another soldier following orders—he’s someone driven by deep principles, even if those principles lead him down a questionable path.

From a psychological standpoint, Justin Law fits the ISTJ personality type quite well. He’s methodical, detail-oriented, and places great importance on structure and tradition. His dedication to the Church of Shibusen and his unwavering commitment to duty highlight his strong sense of responsibility. Justin Law doesn’t cut corners—he follows rules meticulously and expects others to do the same. That said, this same rigidity can make him seem cold or overly harsh, especially when dealing with those who don’t share his strict worldview.

His ISTJ traits also explain why he struggles with change and tends to resist new ideas that challenge the status quo. While his reliability and discipline are definite strengths, they’re balanced by a certain inflexibility that can border on extremism. Justin Law isn’t one to compromise, and that single-mindedness, while admirable in some contexts, can also lead to conflict.

Looking at things from another angle, Justin Law also aligns closely with the Enneagram Type 1—the Reformer. This type is defined by a powerful internal drive for justice, morality, and perfection, all of which describe Justin Law perfectly. He holds himself—and others—to extremely high standards, and it visibly bothers him when rules are broken or ethics are compromised. As Lord Death’s right-hand man, he sees himself as a guardian of order, and that role shapes nearly every decision he makes.

But being a Type 1 isn’t without its downsides. Justin Law’s desire for perfection often makes him judgmental and intolerant of imperfection in others. His anxiety around disorder or moral failure pushes him toward rigid thinking, which may have contributed to his eventual alignment with more extreme factions. While his intentions may be noble, his inability to accept flaws—both in systems and people—can lead to problematic choices.

In the end, Justin Law stands out not just because of his skills or position, but because of the depth of his character. Whether you see him as a hero, a villain, or something in between, there’s no denying that Justin Law brings a unique blend of integrity, intensity, and mystery to Soul Eater. His ISTJ tendencies and Type 1 motivations paint a portrait of someone who believes deeply in doing what’s right—even if “right” means walking a very narrow, uncompromising path. And honestly, that’s probably why so many fans still talk about Justin Law years after the series ended.
