Hirokazu Arai is one of the intriguing characters in the popular anime Chainsaw Man, which originated from a Japanese manga series created by Tatsuki Fujimoto. The show, brought to life by the animation studio MAPPA and directed by Ryū Nakayama, first aired in October 2021 and quickly gained a strong following. Among its diverse cast, Hirokazu Arai stands out—not because he’s loud or flashy, but because of his quiet intensity and unwavering focus.

As a member of the Public Safety Devil Hunters, Hirokazu Arai works alongside familiar faces like Aki Hayakawa and Power. He tends to keep to himself, often seen with headphones on, lost in music, which adds to his somewhat mysterious aura. While Hirokazu doesn’t say much, his actions speak volumes—especially in combat. He’s proven time and again that he’s not just dependable, but also highly capable under pressure. His calm demeanor makes him a reliable presence during high-stakes missions, and it’s no surprise that he’s frequently assigned to some of the most dangerous operations.

When it comes to fighting, Hirokazu Arai relies heavily on his chainsaw sword—a weapon that’s both brutal and efficient. It’s not just for battling devils; he’s also been shown using it to cut through solid obstacles like walls and doors, showcasing both strength and precision. What really sets Hirokazu apart, though, is his level-headedness. Even in chaotic situations, he maintains composure, making split-second decisions without hesitation. This kind of discipline isn’t common, and it’s part of why fans are so drawn to Hirokazu Arai.

Over time, Hirokazu Arai’s role in Chainsaw Man has slowly expanded, giving viewers more glimpses into who he is beneath the silence. Though still somewhat enigmatic, he’s quickly become a fan favorite. People are curious about his backstory, his motivations, and how he’ll continue to influence the story as it unfolds. There’s definitely more to Hirokazu than meets the eye, and future episodes may shed light on his deeper layers.

Looking at his personality, Hirokazu Arai seems to align closely with the ISTJ type—Introverted, Sensing, Thinking, Judging. These individuals are known for their practicality, sense of duty, and commitment to structure, all of which describe Hirokazu well. He follows protocol meticulously, takes responsibility seriously, and consistently performs his duties with precision. Even when the situation gets intense, Hirokazu remains focused and diligent, never cutting corners.

His introverted nature is obvious—he doesn’t seek attention or engage in unnecessary conversations. Yet, despite being reserved, Hirokazu Arai proves to be a trustworthy teammate. He may not express warmth openly, but his loyalty shows through action rather than words. When things go wrong, you’d want someone like Hirokazu Arai on your side—someone who stays calm, follows through, and puts the mission first.

From an Enneagram perspective, Hirokazu Arai also fits the profile of Type 1: The Reformer. He embodies a strong moral compass, a drive for self-improvement, and a desire to uphold justice. He holds himself to incredibly high standards and expects the same level of integrity from others, which can sometimes come across as rigid or critical. But this isn’t out of malice—it stems from a genuine belief in doing what’s right.

Sure, Hirokazu Arai’s strict principles might clash with more laid-back personalities, and his tendency to judge others’ shortcomings could create tension. However, at his core, he wants to make a difference. Whether it’s eliminating threats or mentoring younger hunters, Hirokazu is committed to creating a better, safer world—even if it means shouldering extra burdens himself.

In summary, while we can’t say with absolute certainty, the evidence strongly suggests that Hirokazu Arai leans toward the ISTJ personality type and Enneagram Type 1. His disciplined nature, quiet reliability, and relentless pursuit of perfection define who he is. And as Chainsaw Man continues to evolve, Hirokazu Arai’s journey will likely reveal even more about what drives him—making him not just a background character, but a vital piece of the story’s foundation.
