Gallus Cleaner is a standout character in the anime series Mushoku Tensei: Jobless Reincarnation, and honestly, it’s hard not to be intrigued by him. He’s not just another background figure—he’s a highly skilled magus, widely regarded as one of the most powerful mages in the entire world. What really sets Gallus apart, though, is his sharp mind and exceptional strategic thinking. These traits make Gallus Cleaner an indispensable ally, someone you’d definitely want on your side when things get complicated.

Now, let’s talk about his mysterious vibe—because seriously, Gallus Cleaner’s past is wrapped in secrecy. This only adds to his enigmatic presence throughout the story. He serves within the Noble Holy Church, an organization dedicated to upholding justice and order across the land. And get this—he’s not just any member. Gallus Cleaner is actually one of the elite Cardinal Mages, a title reserved for the most respected and magically gifted individuals in the church. Despite his high status, he tends to operate behind the scenes, quietly pulling strings with his vast knowledge and magical expertise.

Throughout the series, Gallus plays a crucial role in supporting the main cast, especially the protagonist, Rudeus—a former NEET who gets a second chance at life in a fantasy world. Gallus uses his influence and wisdom to guide Rudeus and help him navigate the challenges ahead. In fact, he’s central to exposing a major conspiracy aimed at toppling the church and undermining the Cardinal Mages’ authority. His guidance isn’t just limited to big-picture politics either; he also offers personal advice, showing that beneath his serious exterior, Gallus Cleaner genuinely cares.

All in all, Gallus Cleaner leaves a lasting impression. His intelligence, mastery of magic, and calculated approach to problem-solving make him a key player in the story. Sure, he comes off as stern and no-nonsense, but every now and then, we catch glimpses of a more compassionate side. It’s these subtle moments that make fans keep coming back to analyze Gallus Cleaner’s character even more deeply.

When it comes to personality, there’s a strong case for Gallus Cleaner being an ISTJ—Introverted, Sensing, Thinking, Judging. People with this type are typically practical, detail-oriented, and value reliability over risk. Sound familiar? Well, Gallus Cleaner certainly fits the bill. His dedication to his duties, meticulous attention to cleanliness, and preference for proven methods over untested ideas all point toward an ISTJ mindset. Remember when he hesitated to accept Rudy’s help at first? That hesitation reflects his cautious nature and desire to maintain control over his work.

And while ISTJs can sometimes seem rigid or overly strict, they’re also incredibly dependable—exactly like Gallus Cleaner. Even though he sticks to routine and rules, he ultimately agrees to collaborate with Rudy, showing flexibility and a sense of responsibility. That balance between discipline and duty is classic ISTJ, and it’s clear that Gallus embodies those qualities.

Looking at things from another angle, Gallus Cleaner also shows strong signs of being an Enneagram Type 1—the Perfectionist. This makes a lot of sense when you consider how he approaches his role. His obsession with order, precision, and doing things “the right way” is textbook Type 1 behavior. He holds himself—and others—to extremely high standards, and let’s be honest, he doesn’t hesitate to call out anyone slacking on their responsibilities.

But here’s the thing: while his perfectionism might come off as harsh, it stems from a deep sense of integrity. Gallus Cleaner believes in justice, honesty, and doing what’s morally right, even if it’s unpopular. That makes him a kind of moral anchor in the series. Yes, his rigidity can cause friction, but it also ensures that important values aren’t compromised.

So, wrapping it up, while we can’t assign personality types with 100% certainty, the evidence strongly suggests that Gallus Cleaner aligns closely with both the ISTJ temperament and Enneagram Type 1. Whether it’s his methodical work ethic, his behind-the-scenes influence, or his quiet sense of duty, Gallus Cleaner remains one of the most compelling figures in Mushoku Tensei: Jobless Reincarnation. As the story unfolds, fans will surely continue to appreciate the depth and complexity that Gallus brings to the table.
