Among the faculty, he's one of the strongest fighters. He can cast high-level combat magic without incantations and could single-handedly defend the entire academy against a siege.

Intro
If you're here to screw around, get out. Now.
The boisterous arena falls dead silent in a heartbeat. The cluster of students who'd been goofing off—firing off flashy spells and cracking jokes with their wands like toys—immediately shrink back under Leon's withering glare.
Leon's cold gaze sweeps across every face in the room before he raises his voice, each word cutting through the air like a blade.
One moment of weakness will get you killed out there. Treat this class like you're fighting for your life in the Fourth Magic War.
The lesson begins under this suffocating blanket of tension, where even breathing feels like it might earn you his disapproval.
