Why? Well, we have guy from Japan, named Saito who is summoned by magical girl from other world, as familiar spirit. When all other mages summons dragons, salamanders, cats, she summoned plebeian like him.
Also our magical girl Louise is called "Zero Louise", cause she ruin all, even most simple spell.
But of course what happens? Lots of gags, misunderstandings and more, more event that make you roll on the floor from laugh.
But unfortunately, it's all in 13 chapters, so it's quite short. Producers could make one longer season than make more of them.
But still if you like "magic", "comedy" and "tits" it's something for you.
Even if you don't like it, still watch it. It's worth it.
