The Familiar of Zero Episode Rating Graph

Worried that the princess may be blamed for Fouquet's theft, Louise volunteers to go out and catch her. With Kirche, Tabitha, and Saito tagging along, they travel to the last sighting of Fouquet with Longueville. There, they discover the hiding place of the Staff of Destruction only to have Fouquet's golem appear. Wishing to show her worth, Louise tries to take it head on with a spell, nearly being crushed in the process. Only by Saito's quick reflexes is she saved. Her confidence broken, Louise breaks into tears. Saito is moved by this and begins attacking the golem in her name. After discarding Kirche's sword and drawing Derflinger, the runes on his hands glow once again and his ability greatly increases. Louise tries to help by taking out the Staff of Destruction, which turns out to be a "M72 Light Anti-tank Weapon system(LAWs)" rocket launcher from Vietnam War. Immediately recognizing it, Saito grabs it and quickly uses it, blowing up the golem.

Louise has a nightmare where she loses the ability to cast magic. Awakened, she goes into the forest to attempt to cast explosion. Saito finds Tabitha reading a book, and she began to teach him the words, but Louise interrupts, telling Saito that she can no longer use magic. Tabitha saids that she will protect Saito since Louise is unable to do so. In Tristan, Henrietta dispatches the Ostland and Colbert to rendezvous with Saito, carrying a type of cannon (which seems to be a German Flak88 from WW2), and Agnes offers the assistance of the Musketeer Force. Silently, Colbert hopes the weapon will not be needed. Saito, under Tabitha's guidance, learns to read quickly, while Louise broods over her inability to cast magic. Overhearing Tabitha telling Saito that under the influence of Gandalfr, the heart will experience changes, Louise wonders if Saito loves her because of Gandalfr's influence. Just before crossing the border, a Square-class golem, with Sheffield on its shoulder, lands in front of the carriage and blocking off the route into Tristan. Slyphid and Tabitha take to the air, in order to lead Sheffield away. Guiche, Kirche and Tabitha's attacks prove ineffective against the golem, which is protected by Counter, but they manage to halt the golem's advance with their spells. Saito realises her objective is Louise, and tells her to stay back, but she jumps out of the carriage as Malicorn pulls it back. She is grabbed by the golem, who began to crush her unless she uses her magic. Saito's attacks are easily stopped by Counter, and Louise decides to sacrifice herself for her friends. Saito leaps to attack the golem again, and this time, his attack damages the golem, which releases Louise, and Slyphid saves them in time. Colbert has unloaded the cannon, which Saito examines using his Gandalfr powers, and quickly fires at the golem, but the round is stopped by Counter. Colbert, Kirche and Maricom unleash their most powerful spells, and manage to stop it's advance. Derflinger tells Saito that Dispell needs to be cast on the shells, and Louise refuses, saying she can't do it. Tabitha then kisses Saito, eliciting feelings of intense jealousy in Louise, causing her void powers to be activated again. Louise casts Dispel on the ammunition, which successfully pierces the Counter and destroys the golem. On the Ostland, Louise awakens to see Saito, and asks him if she's okay like this. Saito hugs her, and again declares his love for her, saying he does not love her just because he is Gandalfr. Then Louise kisses Saito while claiming that she has to because he's her familiar. Back in Tristan, Louise kneels before the queen, awaiting punishment for defying her. Henrietta punishes her by awarding her the royal mantle, declaring that Louise is now her sister and second successor to the throne, as well as returning Saito his Chevalier cloak. She then welcomes Tabitha as Princess Charlotte back to Tristan. The ending credits also show Maricom and Guiche wearing their mantles with their school uniforms, signifying that Henrietta has reinstated their noble status. When Louise tries to explode Saito when she sees Tabitha holding onto Saito, Sylphid grabs Saito and escapes with Tabitha.

The gang has located a rare dragon, which Siesta's family has kept a map. It turns out to be a Mitsubishi Zero-sen, a Japanese aircraft use in World War II. They bring it back to the school. Colbert said someone earlier used another aircraft to fly during the solar eclipse and disappeared. Saito concluded that the person returned home and this is his chance for him to return home also.

Julio and Saito continue their battle with the Ancient Dragon, but Saito won’t talk about the loss of his partner. Louise can see the pain on his face and has faced with her toughest decision to date.

With the arrival of Wardes and Louise alone, they meet up with Prince Wales in a seemingly deserted church. After finishing up business, Wardes suggests to Louise that they should just get married right then. Confused and repulsed by the idea, Louise tries to refuse his offer, but one of Wardes' allies comes out with a mind-control ring, forcing her into agreeing. With the Prince as the minister, the marriage proceeds and is nearly completed until Saito bursts into the church. Snapping Louise out of her trance, Saito rushes to rescue her. In response, Wardes kills Prince Wales, revealing that he is in fact involved with the rebels fighting the government Albion called Reconquista.

The lovey-dovey antics of Louise under the love potion persist to the point of freaking Saito out. In desperation, Saito demands that Montmorency create an antidote. She refuses to do so until Saito learns of the illegality of creating love potions and threatens her with possible arrest. As the antidote requires the tears of a water elemental, Montmorency leads Saito and Louise to Lake Lagdorian. There, they find Kirche, Tabitha, and a whole new problem.

Queen Henrietta has ordered everyone to Romalia, once there they meet the Pope of Romalia, Saint Aegis the 32nd. He has summoned them to reveal a secret, one that involves void mages and the fate of the world.

Having been concerned for the welfare of the commoners, Henrietta asks Louise and Saito to work undercover and figure out if what nobles are taking advantage of the lesser ranked commoners. Louise ends up wasting all of the money given to her for the mission on gambling in hopes of having enough to afford an expensive hotel. Refusing to ask for more money, Louise ends up working in a bar as a waitress. Unused to the brashness of a commoner's life, she is unable to earn any tips with her temper flaring all over the place. Her moment of salvation comes when a rather arrogant noble decides to enter the bar.

Saito is trapped in Japan while his friends fight against the Ancient Dragon. Even if he is able to return to Halkeginia, will he make it in time?

Siesta, in an effort to win Saito, challenges Louise to a contest. If he can locate Louise at the Seipnir ball, she will relinquish her advances towards him. Louise accepts, telling Saito that if he succeeds, she will allow him to “continue what he started before”. The ball arrives, and each participant takes a turn at the mirror of truth, which transforms him or her into their ideal self. Saito, on the way to the ball, notices a dark shape flying over the academy. Believing Louise to be in danger, he rushes in and begins to search for her. Locating her on the balcony, he has a brief conversation with her before the two kiss. Sheffield then arrives and disrupts the ball, destroying the mirror and reverting everyone to their former selves. Saito then discovers that the girl he kissed is not Louise, but is in fact Princess Henrietta, who had taken Louise's form. She explains that she has always envied Louise, considering her to be much more courageous than herself. She embraces Saito when he attempts to comfort her, and the two almost kiss again. Louise discovers them in this act and runs away crying, ignoring Saito’s attempts to explain. She is confronted and hypnotized by Sheffield who then takes her captive. While going after her, Saito is confronted by Tabitha, who is now in league with Sheffield. After a brief skirmish, Saito defeats Tabitha, but spares her life. He then manages to free Louise from her hypnosis, whereupon the two are surrounded by enemies. They are saved by a sudden wave of fire magic, originating from Colbert and Kirche, riding the dark shape from earlier, which is revealed to be an enormous flying machine.

It's summer vacation and many students are traveling back to their families. Kirche goes along with Tabitha to her home on invitation, leaving Louise and Saito alone for once. However, mischief is still plentiful. Upset at Guiche's continued flirting with other girls, Montmorency creates a love potion and plots to have Guiche take it. Meanwhile, Saito obtains a large pot that was about to be thrown away and converts it into a makeshift hot tub, similar to the hot springs in Japan. While bathing in it at night, Siesta happens to pass by and much to Saito's embarrassment joins him. Seeing this, Louise becomes so frustrated that she interrupts Montmorency's plans by gulping the drink laced with the before mentioned love potion. As can be expected, when Saito returns to her room, Louise falls completely in love, causing many more problems.

Cromwell launches an invasion on the day of the solar eclipse. Louise heads off to battle as Saito's chance to return home draws near.

An abrupt departure from the normal life he once lead, Saito must deal with being Louise's familiar. Unhappy with the arrogance of nobles, Saito exposes Guiche's two-timing nature as an act of revenge. This of course, provokes Guiche into challenging him to a a duel. Despite being severely beaten up by Guiche's magic, Saito refuses to bow down. Impressed, Guiche tosses him a sword to even up the playing field. In a completely unexpected turn of events, the runes etched on Saito's hands begin to glow the moment he grasps the sword. Feeling a surge of energy, Saito manages to defeat Guiche. However, he soon collapses after the fight from fatigue.

The yearly familiar exhibition is literally a day away and Louise is feeling rather depressed about it. Not only does Saito have nothing impressive to show off, but this year the Princess is watching as well, making it even more important. As night approaches, desperation sets in as Saito is unable to produce an act worthy of praise. A sudden mystery visitor turns out to be Princess Henrietta herself and her relationship with Louise is explained. The next day, Saito attempts a presentation only to be dragged off early by Louise. Walking away from the stage, they witness a robbery in progress by Fouquet and her earthen golem. Failing to stop her, Fouquet is able to run off with the fabled Staff of Destruction.

Louise tries to prevent Saito from looking at other girls, but her plan fails. The newly crowned Queen Henrietta assigns the code name 'Zero' to Louise for a mission. When they get home Louise insists she tell him about the misunderstanding that Agnes said. When he tried to explain she beat him until morning causing bruises all over his body. The next morning, Saito and Louise are informed that Henrietta has been kidnapped.

Tiffania travels back to Tristain with the group. While introducing herself to the Queen, she forced to remove her hat revealing a pair of long, pointed elf ears. Elves are shunned by civilized society, and she explains that she is in fact a half-elf. Her mother was an elf that passed away years earlier, and her father was the archduke of Albion and Henrietta's uncle. As the Queen, Saito, Louise, Agnes, and Tiffania discuss the whereabouts of the other void user(s), Henrietta offers to knight Saito again and he accepts. Henrietta also appoints Siesta as Saito's servant, much to Louise's frustration. Saito, Louise, and Siesta arrive back at the academy by dragon to a huge celebration in Saito's honor lead by the self-proclaimed Knights of Ondine, a group of students at the academy captained by Guiche.

The Ostland makes it to Reynald, Gallia’s Kingdom, where Tabitha has offered to repair the ship. While there she informs them that she is taking the crow and becoming Queen. Louise has the deal with her jealous feelings as Saito spends more time with Tiffa.

It starts off with Siesta at the imp cafe with her uncle and cousin, Jessica, telling her to try harder at getting Saito, eventually giving her a love potion. After the credits, it goes to Saito and Louise’s room where Siesta is cleaning and contemplating using the potion on Saito when Louise comes in dragging Saito who is tied up behind. This causes a fight between Louise and Siesta about the treatment of Saito. Finally, Siesta who believes that she can take better care of Saito than Louise is allowed one hour for that purpose. When the two of them get to Siesta's house she decides they should play newlyweds but after several chances she finally decides to use the potion only to drop it out the window where it is found by Montmorency who imeadietly identifies it as a love potion but accidentally inhales it and the first person she looks at is Louise who has come to check up on Saito, but after Montmorency kisses her it is discovered the potion is more like a virus and it is eventually left for Tiffania to sort out. Tiffania uses a long-forgotten spell to wipe the memories of all those affected by the charm, and Montmorency forgives Siesta for causing the mess, reminding her not to do it again. Tabitha is later confronted by Sheffield, who attempts to sway the young girl by tempting her with promises to save the former's mother.

As the Ostland flies at max power to the elven land, Saito and Tiffa are put before the council to decide their fate. Eshmael provoking words causes Saito to lash out, causing the other council members to agree that the barbarians must be destroyed. Will the Ostland make it in time or will a war start with the elves?

King Joseph new weapon is a bomb fueled with Louise’s Explosion spell. Will Saito, with the aid of a new “out of place relic,” reach Louise in time before she makes the ultimate sacrifice?

Albion sends hired mercenaries to make a surprise attack on the Magic Academy and take all of the people from the royal families hostage. Saito and his friends plan on how they will rescue the people taken hostage as it will take too long for the reinforcements to come from the palace. It is discovered the captain was one of those who attacked Agnes's town D'Angleterre's and burnt it to the ground 20 years ago.

Henrietta has a special mission lined up and Louise and Saito are the perfect candidates. But Saito hesitates to go into battle because of what Mr. Colbert mentioned before.

Despite being from a famous magic family, Louise has never been able to successfully cast a single spell. On the day of her familiar summoning exam, she bungles the summoning and accidentally summons a human from Earth. The poor victim of her mistake is Saito Hiraga, a typical high school boy.

The episode begins with the Ondine Knights searching for something when a nude girl drops forn the sky onto Malicorne in the same fashion as when Louise lands on Saito in the opening. Louise kicks Saito in the groin and sends him to the ground then proceeds to ask the girl why she is naked. She introduces herself as Irukukwu. She keeps talking about saving her older sister until Guiche asks her about her older sister, who turns out to be Tabitha. She says how Tabitha was taken as a traitor and stripped of her chevaliar title and how Tabitha's mom was arrested. She continues to tell that Tabitha went to save her mom, but was captured in the process. When Irukuwku asks for help, Malicorne and Saito volunteer promptly, but the others doubt her status as Tabitha's younger sister (on the face that Tabitha is pretty flat-chested and that Irukuwku has huge tits). Irukukwu thinks about obtaining proof and rushes out of the door. The Ondine Knights rush out of the door as well, only to find that Irukukwu has vanished. Not long after, Sylphid appears and testifys for Irukukwu. Saito, Guiche, Malicorn and Louise go to Henrietta to ask for permission to go and rescue Tabitha, which she denies on the grounds that as her personal knights, if Tabitha is rescued by the Ondine Knights, as she is considered a criminal, the rescue could be perceived as an act of aggression on Tristan's part. In response, Saito, Guiche and Malicorn resign as knights in order not to trouble Tristan, and Henrietta responds by having them arrested. Louise asks Henrietta what she thinks of Saito as a man not a chevalier, and Henrietta admits that she is not sure if she has fallen for Saito or simply needs someone to lean on. Louise gives up her position as a noble, declaring that she wants to help Tabitha, to repay her for all the times Tabitha has saved her. Henrietta has no choice but to have her arrested as well. After trying, unsuccessfully, to dig their way out of the prison with spoons, the four get rescued by Kirche and Colbert. Irukukwu reveals that she is really Slyphid, which is a rhyme dragon and capable of transforming into a human form.

Colbert sensei and Saito devise a plan to enter into the building and save the hostages. Benubiro explains to Anies how his captain Snake of the Flame ruthlessly burnt the women and children to ashes. The team use their combined magic to enter the building. During the attack, Benubiro recognises Colbert-sensei who is in fact his captain Enja, Serpent of the Flame. The two enemies begin a heated battle. Agnes becomes furious and charges towards Colbert sensei. Benubiro fires a lethal fireball towards Agnes to stop her from interrupting them, Colbert-sensei pushes her away from the blast and is struck in the crossfire. Agnes takes her revenge for her town upon Benubiro and defeats him. Colbert-sensei in his last moments explains what had occurred on that fateful day. He had been given orders to destroy D'Angleterre's Town as it had been reported to be struck with a deadly plague. After discovering there was no plague, he discovers a girl (Agnes) the only survivor and he carries her to safety. Agnes is still infuriated and she holds up her sword to strike a final blow to Colbert-sensei, but he dies before she can do so. Louise and Saito are saddened by the death of their teacher, whereas Agnes is still undecided if she will ever forgive him.

Julio Cesare transfers to Louise's school and shows an interest in her. He challenges Saito to a fight in which the winner gets to kiss Louise. Saito receives special training from Agnès but Louise shows up and attacks Saito in a jealous rage yet again. He fights against Julio the next day, but Julio loses on purpose.

Henrietta's forces enter South Gotha and claim it. Scarron's traveling tavern sets up shop, and Saito and Louise are reunited with Siesta, Jessica, and Guiche. Guiche shows off a medal and relates a story of coming back from the dead, which no one believes. Using the Ring of Andavari, Sheffield causes some of Henrietta's troops to attack the city from within.

After the events of the last episode, Saito was forced, in his boxers, to read aloud and sign a pledge admitting that he took advantage of Tiffania in the infirmary. However, he refuses to sign it, insisting that it was she who asked him, and leaves. Upon seeing the shack where Professor Colbert kept his books and other materials, he entered and sadly remembered the teacher's wish to someday visit Saito's world. He apparently starts to doze off, but wakes up after hitting his head on the table. His attention then turns to the piles of gifts being left for Guiche and Reynald, and inquires as to their meaning, in which case, Reynald explains that gifts from the ladies are becoming more common after the fight with the Air Dragon Knights from the previous episode. With love seemingly in the air, Saito remembers the fight with Louise and becomes rather depressed. Upon seeing this, Guiche, Malicorne, and Reynald grow determined to cheer him up. A newcomer in the Knights of Ondine, Gimli, comes up with an idea, and they set about to digging a hole to the women's bathhouse, where they use magic to create a small peephole, bringing Saito along to join them. In the bath, Tiffania explains to Louise that it was she who asked Saito to touch her breasts. This leaves Louise a bit upset over her treatment of him, realizing that she didn't even bother to listen, and fears that he may not come back. However, when Tiffania makes the statement that the two are lovers, Louise immediately shoots that notion down. Saito yells for them to stop peeking at her, and his loud voice gathers the attention of Tabitha, who speaks up. The hole is noticed, and their fun is over. They manage to escape, but are found and swiftly punished by the girls. Saito, however, is saved by Tabitha (as a favor for him feeding her dragon earlier in the episode). When Montmorency comes into the dining hall looking for Guiche, Tabitha hides Saito in a rather provocative manner--by pressing her naked body up against him. When word that Guiche has been found, she heads off, but the sound of whispers gains Tabitha's attention, and she soon passes out from fear of ghosts. The dolls appear and start dancing, and Saito is reminded of the party from the first season. Louise shows up, explaining the nature of the dolls' appearance. She has him admit to being with the others who were peeking, but he explains that he was deceived, half expecting her not to believe him. She believes him, though, and they embrace. However, the embrace comes to an abrupt end when Tabitha wakes up for a brief moment, and once again, Louise gets the wrong idea. He ends up in the same position as in the beginning, only this time the pledge is for him never to touch breasts smaller than Louise's (or anyone else, for that matter). In protest, Siesta grabs Saito's hand and rests it on her breast, and in a rage, Louise blows him up.

Henrietta is convinced to sign a declaration of war against Albion. News of a victorious battle for the Tristain and Germania allied forces reaches a town that Louise and Saito are currently in. Saito discovers a sailor uniform on sale at a clothes merchants shop, and buys it, opting to give it to Siesta rather than to Louise. Upon returning to the academy, the two join Agnes and Julio on exploring a secret archive hidden beneath the school, which Agnes was denied permission. Agnes wishes to obtain the information there regarding her home town of D'Angleterre's burning to help carry out her revenge against those involved. Eleonore is picked to open to lock to the entrance. As the group heads farther down, they are joined by Siesta, who is wearing the sailor uniform Saito gave her earlier. After discovering that Saito gave the sailor uniform to Siesta because Louise lacked the chest size to make it look good, Louise blows a part of the cave in the way they came. With little to do but move further, the group finds the archives and are sent to look for the records regarding the town of D'Angleterre's burning 20 years ago. When Siesta trips and makes a mess of the books, Eléonore returns them to their proper place with magic, which triggers the archives' security system and begins to bring the bookshelves to a close. Agnes finally finds the information regarding D'Angleterre's burning, but a part of the page that lists the person who led the attack is missing. The group narrowly escapes the collapsing of the bridge that led them to the archives. Upon realizing that Louise had blocked their way out from before, Julio grants Saito permission to have intimate moments with Siesta. Siesta is happy to oblige and Saito also thinks it to be a good idea, however, Louise is watching and is preparing to blow something else up. When Saito points out that the cave in she made earlier is in the opposite direction, Louise tells him to shut up and blows them up anyway.

Saito and company take refugee in the Charming Fairy Inn while the search for them continues. A plan is created to use the Ostland to fly towards Germinia as a decoy, while Saito goes across the border directly. Scarron provides disguises for them, while Colbert, Seista, Gimli and Reinard proceed to liberate the Ostland. Siesta shows doubts at first of not having any powers but gets encouraged by Saito that she could still help. She hugs him so Louise kicks him in the groin from behind. In Gallia, Joseph and Sheffield uncover a massive object, which Joseph calls Jormungand, covered with pulsing veins and with a single large eye. Posing as a travelling circus, Saito and company cross the border, while Louise broods over no longer being an aristocrat, realising she only has Saito left. Back at the castle, using Siesta as a distraction, Gimli and Reinard take out two guards and they board the Ostland, after dispatching two more groups of guards. Colbert quickly fires up the Ostland, eventually ripping free of the chains that are tying it down. Agnes falls for the ploy, ordering guards to watch the Germinia border. Louise sprains her ankle, and Saito tells her to rely on her, carrying her on his back. She wonders how Saito is so strong, despite being alone in this world. The Ostland is eventually stopped by Tristan dragon knights, and Agnes nearly kills Colbert upon seeing him. Meanwhile, Saito and company arrive in Gallia.
