Louise Françoise le Blanc de la Vallière (ルイズ・フランソワー・ル・ブラン・ド・ラ・ヴァリエール, Ruizu Furansowā ru Buran do ra Variēru) is one of the two title characters and the female protagonist of the series, The Familiar of Zero. She is a sophomore Void aristocrat and the wife of her familiar spirit, Saito Hiraga. She was famously but negatively known as "Louise the Zero" throughout Tristain Academy of Magic because of her consistency in casting failures while performing magic. After marrying Saito, she is later known as Louise Françoise le Blanc de Hiraga de Ornielle (ルイーズ·フランソワーズ·ル·ブラン·ド·平賀·デ·オルーニユェル, Ruizu Furansowāzu ru Buran do Hiraga do Oruniērū).

Character History

Louise 8

Louise as a child

Louise is the third and youngest daughter of the three children of the Duke of La Vallière and Karin de la Vallière. She always argues with her eldest sister, Eléonore, but is very attached to her older sister, Cattleya. She was adopted by her childhood friend, Princess, and later Queen of Tristain, Henrietta de Tristain.

At the Tristain Academy of Magic, Louise is a sophomore and the rival of Kirche von Anhalt Zerbst as their families are rivals as well. She is very popular amongst the students, plebeians, and even the staff but in a negative way. For instance, if an explosion occurs, they conclude that it is caused by Louise, but is usually true. Louise's familiar spirit is Saito Hiraga who is a Gandálfr.

Louise temporarily stays in a dormitory at the Academy during weekdays. However, she returns to the La Vallière mansion probably during weekends. When Saito became her familiar spirit, he lives with her. He sleeps at the floor at the start of the series, but eventually slept with Louise on her bed until they were married, wherein it was presumed that they reside at Saito's home in Japan.

At the season finale of the fourth season, Louise was married to Saito Hiraga, and she was therefore known as Louise Françoise le Blanc de Hiraga de Ornielle. She opened the portal on the way to Japan together with her husband, and she was brought to Saito's home. It is unknown on what happened with Louise and Saito at his house, but she is probably introduced to his family and they lived together in their new home.


Familiar Spirit Summoning Exam

Louise completes the contract by kissing the human

The day before the Familiar Spirit Summoning Exam, Louise confidently told Montmorency, Kirche, and Tabitha that she would not fail in the Exam. On the day of the Exam, Louise was the last sophomore to perform the ritual. She summoned a human from another world and turned out to be unconscious. As the students laughed at a "plebeian" familiar spirit, Louise asked Professor Colbert if she could redo the ritual. She cannot do so as the ritual was very sacred, leaving her no choice to complete the contract. As the human woke up, he was forced to kiss Louise as the contract. After this, runes on his left hand appeared, which read Gandálfr.

Life as a Master

As a master to her familiar spirit, Louise is vain to Saito, treating him like and calling him a dog. Whenever he does something rude or wrong, she whips him or sometimes beats him up with her magic. Though bossy sometimes, Louise cares and dearly loves Saito, being strict on him looking at other girls. For instance, she gave him an absolute rule to look at no other women but to his master only. Oftentimes, when Saito is with other women, Louise easily gets envious and irritated, beating and whipping him. Also, when Louise had had enough of Saito's tactics on looking at other women, she gave him a pair of Medusa Glasses. When Saito looks at other girls, the glasses glow, giving Louise a hint and a reason to beat him up.

Giving Derflinger to Saito

Ep 3

In order to protect her, Louise bought Saito a cheap sword. While buying him a sword, she did not have much money then, buying him a cheap one. To match Louise's sword, Kirche bought Saito an expensive sword, much to Louise's anger. When they confronted the golem of Fouquet, Saito used Kirche's sword to battle with it, but broke. Leaving him no choice, he used Louise's sword and successfully defeated it. After the incident, it is revealed that the sword Louise bought is Derflinger, the talking sword.

Forced Marriage to Wardes

Ep 11 4

Louise unconscious during her wedding

Louise was forced to marry her fiancé, Jean-Jacques Wardes. She was controlled during her marriage to him at Albion when she was supposed to give a letter to the Prince from Princess Henrietta. With the Prince officiating the wedding, Saito broke into the church to stop the almost-finished ceremony to save Louise. The spell was broken, but the Prince was stabbed to death by Wardes, revealing that his allegiance lies to Reconquista and that his mission is to steal the letter.

Louise and Tiffania with other three women were assigned to be the priestesses of the Pope.

Henrietta hypothesized that she might have been past Aquileia's border already. After Louise awakes after being paralyzed by Jeanette, she found out that she was kidnapped by the Gensō Siblings ordered by King Joseph de Gallia.

Battle Against the Ancient Dragon

Louise's efforts in fighting the Ancient Dragon were not effective because her familiar spirit was away. When Saito returns to Halkeginia, he was of great help to Louise. Using the power of Gandálfr and Lifdrasir, they were able to partially defeat the Dragon, and was utterly defeated by Louise's Explosion.

After defeating the Ancient Dragon, Saito proposes to Louise in front of the others to marry him, to which Louise agrees. Louise and Saito marry at the Church wherein she was known as Louise Françoise le Blanc de Hiraga de Ornielle. Afterwards, Louise opened the portal (Louise probably performed World Door) all the way to Japan to live in their new home.


Louise 4

A sophomore at the academy, Louise looks like a young lass because of her height. She has long curly pink hair and corresponding color for her big eyes. Her uniform includes a long-sleeved blouse underneath a long indigo coat reaching her feet, a black skirt, and a pair of long black stocking-like socks and puts on a pair of black shoes. She is also shown to carry her wand with her all the time.

Plebeian Attire

Louise's prize after winning the Tip Race

After winning the Tip Race, Louise wore an outfit which consisted of a black ponytail, a black, tight necklace, a tight, black dress with a pair of matching-colored, tight arm warmers. Down to her legs, she wore black, long stockings and black sandals.



Upon summoning Saito, Louise hates it so much, that it came from herself that she wanted a familiar spirit like a griffin or something. Some examples on how Louise expresses her "hate" towards Saito is by beating him up with her magic and by striking him with a whip. However, as the series succeeds, her love for Saito gets deeper and more intense.


As the two were childhood friends, Henrietta and Louise get along well. When Henrietta orders Louise commands, Louise accepts it enthusiastically, without doubts. Louise is also called by her first two names by Henrietta.


Coming from herself, Kirche "cannot lose to a Vallière" like Louise. With this, Louise hated Kirche, and Kirche hated Louise, too. When Louise bought Saito a sword for "protecting" himself from Kirche in the third episode of the first season, Kirche cannot accept it, and also bought Saito a sword. When Louise sees Saito with other women especially Kirche, Louise quickly gets jealous and envious.
