Atsuya Kusakabe is a well-regarded supporting character in the widely popular anime and manga series Jujutsu Kaisen. As the principal of Kyoto Jujutsu High—one of only three prestigious jujutsu schools in Japan—Atsuya Kusakabe plays a pivotal role in shaping the next generation of sorcerers. Known for his strength and wisdom, Atsuya Kusakabe commands respect from both students and fellow sorcerers within the jujutsu community.

One of the most defining aspects of Atsuya Kusakabe’s personality is his deep sense of care and protection toward his students. Though he leads Kyoto Jujutsu High, he doesn’t hesitate to extend his mentorship to visiting students from Tokyo Jujutsu High—Yuji Itadori, Megumi Fushiguro, and Nobara Kugisaki. During their time at Kyoto, Atsuya Kusakabe takes a special interest in them, recognizing their raw potential and guiding them with patience and insight. He genuinely wants to see them grow stronger, not just as fighters but as individuals.

What really sets Atsuya Kusakabe apart is his calm and composed nature. Even under pressure, he remains level-headed, which makes him a reliable leader during high-stakes situations. His ability to analyze complex scenarios and devise effective strategies highlights his sharp intellect. It’s clear that Atsuya Kusakabe values logic and precision, often relying on observation before taking decisive action.

Beyond being a mentor, Atsuya Kusakabe also serves as a kind of father figure to many of the younger sorcerers. His compassion and quiet dedication show that he’s more than just an authority figure—he truly cares about the emotional and mental well-being of those under his guidance. In this way, Atsuya Kusakabe embodies the ideal of a wise, experienced mentor who helps others unlock their full potential.

When it comes to personality typing, Atsuya Kusakabe seems to align closely with the ISTP type. ISTPs are typically logical, practical, and hands-on—and Atsuya Kusakabe fits this mold perfectly. For instance, he has a passion for mechanics, often spending time dismantling and repairing machines. This hobby not only reflects his technical skill but also his problem-solving mindset. He’s not one to act impulsively; instead, Atsuya Kusakabe prefers to observe, assess, and then move with purpose.

Now, while he may come across as distant or reserved, that’s not because he lacks empathy. Rather, Atsuya Kusakabe conserves his energy and focuses on what matters most. Independence is important to him, and he prides himself on self-reliance—a hallmark of the ISTP personality. He sticks firmly to his principles, especially when they’re grounded in reason and personal experience.

That said, Atsuya Kusakabe isn’t without his rebellious side. There are moments when he pushes back against authority, particularly when rules seem unnecessary or unjust. This impulsive streak reveals his deep desire for autonomy and flexibility—qualities that many ISTPs share. He doesn’t like being boxed in by rigid systems, and that sometimes puts him at odds with higher-ups.

Looking at things from another angle, Atsuya Kusakabe also displays strong traits of an Enneagram Type Six, commonly known as “The Loyalist.” He is deeply committed to his school and organization, showing unwavering loyalty and a strong sense of duty. Safety and stability matter a lot to him—not just for himself, but for his students and colleagues too. He respects hierarchy and follows protocols, believing they help maintain order.

However, this loyalty can sometimes become a double-edged sword. At times, Atsuya Kusakabe follows orders without questioning them, even when doing so might lead to complications. His fear of instability can trigger anxiety, causing him to second-guess decisions or doubt his own capabilities. These tendencies reflect the internal struggles that many Type Sixes face—wanting to do the right thing but being held back by uncertainty.

All in all, Atsuya Kusakabe stands out as a complex and thoughtful character whose actions are guided by logic, loyalty, and a genuine desire to protect others. Whether through his ISTP-like practicality or his Enneagram Six need for security and trust, Atsuya Kusakabe’s personality adds depth to his role in Jujutsu Kaisen. While personality types aren’t set in stone, the evidence strongly suggests that Atsuya Kusakabe embodies the strengths—and challenges—of both the ISTP and Type Six profiles. And honestly, that’s part of what makes Atsuya Kusakabe such a compelling presence in the series.
