Gary Sue #253 meets tsundere girl #253 in a magic school, let the yelling, fan service, and bad animation start.
Story: don't worry about this, it's really not important and if you've seen an anime like this you'll see the beats a mile away.
Art: Same face characters and over the top weapons that just look fake. I guess the outfits are ok sometimes and while still the shots look ok at times.
Sound: I remember zero of the music from this and since a lot of the animation in action shots are off, so is the sound for the attacks.
Characters: Just go on some trope web site and look up the top tropes for anime characters, it's all you'll need to know.
Enjoyment: It's not even bad like watching a bad movie for a laugh, it's just bad.
