As much of a nuisance he is, Glenn Radars is still a loveable character. Aside from his lax nature, he has some quirks that appeal to the general anime community. I guess it’s how Glenn is portrayed in the series and how all of his nook and crannies help build him as a character. The bastard magic instructor won’t be appealing if he were to be nice, and all politically correct to everyone. It will make the character dull and boring therefore taking out the ‘flavor’ or ‘seasoning’ out of this anime since the series seem to focus on him as the protagonist.

As the series progresses, you can see there is quite a few slapstick comedy revolving Glenn Radars. It fitted well, as the character is already a goofball. Adding the comedy essence to this character is ‘a cherry on top’, resulting in a loveable character.

I’m sure a lot of you reading this now is probably a student now or were a student at some point in your lives. With that being said, teachers have played a very important role in our learning process. You are bound to meet teachers, some are good, in terms of how they teach and some are bad, as they come out boring. It’s not easy to teach in an interesting way.

Glenn Radars is one of those teachers that pulled it off. Despite his lacking motivation to teach, when he does teach, it’s a treat for his fellow students. You can see it in episode 2 of the series, as he criticized how it’s stupid to follow what the textbook to the T, without having to understand the fundamental basics of magic.
Personally, I can relate to this situation, we see it in our lives all too often, as teachers teach according to the textbook and we end up ‘memorizing’ instead of understanding what the lessons really meant. If there’s one teacher that does a great job in teaching, Glenn Radars is considered to be one of them.

He might appear to be full of himself, Glenn Radars is actually a kind-hearted person. As shown in episode 3 of the series, when the academy is under attack by terrorist, Glenn stepped up his game and risked his life to protect his fellow students. It got to the point where he ignores his severe wounds just to save the Academy from blowing up.

His decision earned him major points of trust from his students, one, in particular, is Rumia Tingel, where it gave her the dedication to save Glenn from dying, transferring some of her powers to Glenn and giving him that one extra push to disable to curse and save the entire academy.

Although at this point in time, there isn’t much of Glenn Radars’ past that have been revealed yet. But throughout the series, there were hints suggesting that Glenn Radars’ mysterious past has something to do with his previous role as the Mage of Justice. This assumption is backed up by some of the things that happened in the series, one of which where Rumia’s past was somehow connected to this Mage of Justice figure, and how Glenn Radars have outstanding magical abilities, in-depth knowledge and hand-to-hand combat that were on par with the military. If there’s one thing that is interesting about Glenn Radars, is his past.

If you have read the previous paragraphs, you will come to the conclusion that Glenn is a loser of a substitute teacher that does nothing but slack off. But, in episode 4 of the series, you can see that Glenn Radars was able to specifically identify each of his students’ strengths, which come to show that he really pays attention to his students and are aware of their potentials.
He was able to make sure all of his students participate in the upcoming magic competition and utilizing their potentials to the fullest. There is a catch though, his intentions weren’t that noble after all, and it was revealed that he was actually short on an allowance and was aiming to get extra allowance for winning the competition. Yep. He is still a bastard of a magic instructor.
