Louise Françoise Le Blanc de La Vallière's name is longer than her list of positive accomplishments at the Tristain Academy of Magic. Cursed by her fellow students with the horrible nickname "Louise the Zero", she hopes that summoning a surprisingly strong Familiar will turn her luck around... but instead of some cool mythical creature, Louise summons a normal human from Japan! Now Sato Hiraga is magically bound to an incompetent sorceress, but there may be more to her seemingly mediocre magical powers than meets the eye in the spellbindingly complete collection of FAMILIAR OF ZERO!
