Suppose a Kid from the Last Dungeon Boonies Moved to a Starter Town, Vol. 2 (light novel‪)‬

When legend comes to life
Other than confronting his chronically low self-esteem, it seems there's nothing Lloyd Belladonna can't do-whether it's withstanding brutal military drills or knocking the wind out of his fellow cadets with one of his beginner spells. Naturally, this includes pulling out the unbudgeable Holy Sword while he's on cleanup duty...which he promptly mistakes for a piece of trash?! Though Lloyd is too oblivious to know it, his little King Arthur moment will throw an unexpected wrench into the upcoming sorcery tournament, where more absurdities await!
