Glenn Radars is one of the central figures in the anime series Akashic Records of Bastard Magic Instructor, also known as Rokudenashi Majutsu Koushi to Akashic Records. At first glance, Glenn comes across as a laid-back and seemingly indifferent substitute teacher at the prestigious Alzano Imperial Magic Academy—a place where aspiring young mages train to master their craft. But don’t let that lazy exterior fool you. Beneath his apathetic demeanor lies a remarkably skilled and battle-hardened mage, more than capable of handling even the most dangerous threats with surprising ease.

Now, here’s the thing about Glenn Radars—his past is pretty mysterious. We eventually learn that he was once part of the elite Imperial Court Mage Corps, an organization tasked with defending the Alzano Empire from magical dangers. For reasons not immediately clear, he left that life behind and ended up in the classroom, swapping high-stakes missions for lesson plans. And while he might act like he couldn’t care less about teaching, Glenn consistently proves himself to be deeply compassionate. When it really matters, he’ll go to great lengths to protect his students and those close to him.

At the beginning, Glenn’s lack of enthusiasm makes him seem like just another unmotivated temp. But over time, his unorthodox teaching style and relaxed attitude start winning people over. Students begin to appreciate how he tailors lessons to their individual needs, pushing them to grow in ways traditional instructors never could. He especially forms strong bonds with a few key students—like Sistine Fibel, a diligent and passionate mage who gradually becomes more than just a student to Glenn, and Rumia Tingel, a quiet girl hiding a painful past. Through these relationships, Glenn Radars evolves from a detached figure into someone truly invested in the well-being of others.

It’s also interesting to look at Glenn Radars through the lens of personality types. In terms of the Myers-Briggs system, he fits the INTJ profile quite well. That means he’s strategic, logical, and highly independent—someone who thinks several steps ahead. This shows up clearly in how he approaches magic and combat, always analyzing situations before acting. He doesn’t follow rules blindly, which sometimes makes him come off as cold or aloof. While this makes him an incredibly effective instructor and tactician, it can also create emotional distance between him and the people around him.

Then there’s the Enneagram perspective. Glenn Radars strongly aligns with Type 5—the Investigator. These individuals are typically curious, insightful, and deeply analytical, often diving into complex subjects with intense focus. Glenn’s mastery of magic theory, spellcraft, and weapon mechanics all point to this intellectual drive. He spends a lot of time in his lab, absorbed in research, sometimes to the point of neglecting social interactions. It’s not that he dislikes people—he just values knowledge and self-sufficiency more in the moment.

That said, when Glenn Radars does open up, he reveals a surprisingly loyal and caring side. Around those he trusts, he can be warm, supportive, and even show a bit of dry humor. It just takes time for him to let his guard down.

So, putting it all together, Glenn Radars is far more than just a lazy teacher slacking off at a magic school. He’s a layered character—intelligent, reserved, and quietly heroic. Whether it’s outsmarting enemies, mentoring students, or confronting his own past, Glenn Radars remains a pivotal presence throughout Akashic Records of Bastard Magic Instructor. And despite his tendency to keep to himself, his impact on those around him is undeniable.
