Story
In the world of Zero no Tsukaima, everyone who can use magic is a mage or noble. Everyone else is a commoner and is treated less equally. Louise can never use her magic the way she wants to and every time she uses it there always seems to be an explosion (but there might be something hidden inside of her). Louise attends an academy for mages and is always getting into trouble and has been dubbed the name "Louise the Zero", because she can't use any of the four elements, which are fire, water, earth, air/wind. There also is a fifth element called Void that has become nothing but a legend. On the day of summoning their familiars (a special day where a mage summons their eternal protector/partner, which usually is some sort of creature) Louise summons a human from planet Earth. Louise is totally humiliated. She treats "Saito" her human familiar as any other creature, making him sleep on the floor and eat leftovers (upon other actions). One day Saito challenges a noble who thinks he is better than commoners to a duel. Saito is beaten bad at the beginning, but once a sword was put in Saito's hands he gains amazing powers and wields the sword with great ability. Louise and Saito during the course of the story face many mysteries and uncover unexpected truths.
