Layfon Alseif is the main character from the anime series Chrome Shelled Regios, also known as Koukaku no Regios. Right from the start, Layfon Alseif stands out as someone with a mysterious past and extraordinary abilities. He used to be a student at the Military Arts Academy in Zuellni, but things didn’t go smoothly for him there—eventually, he was expelled for breaking the rules. After that, he retreated to the abandoned city of Grendan, trying to live a quiet life as a bodyguard, staying under the radar.

But of course, someone like Layfon Alseif can’t stay out of the action for long. His skills are just too remarkable to ignore. Before long, he’s recruited into the 17th Platoon, and it doesn’t take much time for everyone to realize how valuable he truly is. With his sharp mind, quick reflexes, and unmatched swordsmanship, Layfon Alseif quickly becomes one of the most trusted members of the team. He’s not flashy about it—he’s calm, collected, and always focused on the mission at hand.

As the story unfolds, Layfon Alseif learns about a massive threat looming over humanity—the Filth Monsters. This forces him back into the world he tried to leave behind. Driven by duty and a deep sense of responsibility, he rejoins the academy and leads his platoon into battle. Protecting those he cares about becomes his top priority, even as he uncovers some disturbing truths about the very organization he once served without question.

It’s fascinating to watch Layfon Alseif evolve throughout the series. At first, he comes across as a lone wolf, someone who prefers solitude and keeps emotions in check. But over time, he grows into a true team player, forming strong bonds and learning to rely on others. His journey is full of challenges, moral dilemmas, and personal revelations, which makes Layfon Alseif such a compelling and relatable character.

Many fans find themselves drawn to Layfon Alseif because of his quiet strength and unwavering loyalty. He’s not one to boast or seek attention, yet his actions speak volumes. Whether he’s analyzing a battlefield or stepping in to protect a teammate, Layfon Alseif consistently shows courage, intelligence, and integrity. These qualities have earned him both respect from his peers and admiration from viewers.

When looking at his personality more closely, Layfon Alseif seems to fit the ISTP type in the MBTI framework. He’s clearly introverted, often keeping his thoughts to himself and observing before acting. His sensing trait shines through in combat—he’s incredibly aware of his surroundings and reacts with precision. The thinking aspect comes through in his logical decision-making; he doesn’t let emotions cloud his judgment. And as a perceiving type, Layfon Alseif is adaptable, able to shift strategies on the fly when situations change unexpectedly.

This combination makes Layfon Alseif exceptionally effective under pressure. He stays cool even in life-or-death moments, assesses threats methodically, and uses his physical prowess to handle whatever comes his way. While he might seem distant or reserved at times, it’s not because he doesn’t care—it’s quite the opposite. Layfon Alseif deeply values the people around him and will put himself on the line without hesitation to keep them safe.

Beyond MBTI, Layfon Alseif also exhibits traits commonly associated with Enneagram Type 9, the Peacemaker. He naturally avoids conflict and wants harmony within his group. He’ll often try to mediate or find compromises, sometimes to the point where he hesitates to make tough calls. This desire for peace, while noble, can occasionally lead to passivity or internal struggle when decisive action is needed.

At the same time, there’s a clear Type 6 influence in Layfon Alseif’s behavior—he seeks security, trusts established systems, and feels a strong need to protect his community. He looks for guidance and structure, especially early in the series, which reflects his underlying need for stability and belonging. This blend of Type 9 and Type 6 tendencies shapes a personality that’s cooperative, loyal, and protective, though sometimes conflicted when independence and assertiveness are required.

All in all, Layfon Alseif is a complex and well-developed character whose growth resonates with many viewers. From a solitary figure trying to escape his past to a courageous leader embracing his role in a larger cause, his arc is both inspiring and emotionally engaging. While personality types like ISTP or Enneagram 9w6 aren’t absolute labels, they do offer useful insights into why Layfon Alseif acts the way he does.

In the end, Layfon Alseif remains one of the standout protagonists in Chrome Shelled Regios—a hero defined not by grand speeches, but by quiet determination, skill, and heart. And whether you’re analyzing his psychology or simply enjoying his journey, Layfon Alseif leaves a lasting impression.
