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.

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.

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.

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.

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.

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.

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.

Are Louise and Saito being sent on a suicide mission? Before they even consider their safety, the couple has one last thing to accomplish and Louise wants to make a covenant.

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.

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.

With his recent victory over Guiche, Saito has become semi-popular among the commoners and several nobles. Kirche in particular has chosen him as her next boyfriend. In a devious plan, she attempts to seduce him, although this fails when Louise finds out. Annoyed by Saito's lack of defenses, Louise drags him out to town to pick up a sword after considering his hidden talents. Kirche, unwilling to let go so easily, matches Louise's gift with a more impressive sword. Of course, it simply causes more problems between Saito and Louise.

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.

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?

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.

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.

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.

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.

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.

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.

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.

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?

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?

While they are traveling to the village where Tiffannia is living, they meet up with Siesta who is carrying cooking supplies and food. At the same evening, while they were having dinner, Louise gets into another fight with Saito and walks off. Agnes, who was making a wooden sword, asked Saito to train a little bit. The next morning while they are traveling, Saito sees Tiffania and chases after her. At first she doesn't recognize Saito but after shouting her name a few times, she turns around and hugs him. Louise and Siesta are jealous when they see how big Tifannia's breasts are. The same evening Louise tries to ask who she is, and Saito explains that she saved him during his battle. Out of spite, Louise starts to fondle Tifannia's breasts. But when Saito stops her, Louise runs away and Siesta follows her. After forming a temporary alliance against Tiffania, the two get attacked by Sheffield. Louise tries to protect both of them against Sheffield, but her void magic isn't strong enough. Out of desperation, Louise tries to summon Saito as her familiar again even though it seems impossible. To her surprise, Saito appears and Sheffield was thrown off guard. Due to this, Sheffield retreats and Saito and Louise renew the contract with a kiss. Saito gets the "Gandalfr" runes burned into his hand again.

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.

Saito begins training daily with the Knights of Ordine. This leads to him not having as much time to spend with Louise, arousing her jealousy once again. Matters only become worse when Tiffania shows up as a transfer student at the academy. A student named Beatrice, whom is revealed as royalty, becomes suspicious of Tiffania when she refuses to remove her hat. After telling her that she will remove the hat eventually, Tiffania decides to reveal her true identity as a half elf. Upon the revelation, Beatrice proclaims that she has the authority of the Pope and insist that Tiffania be put through a heretical interrogation. She proclaims that if Tiffania believes in the true god, she will be able to step into a pot of boiling water she has had prepared. Saito shows to stop her, but upon hearing from Guiche that Louise would be in trouble he interferes, he bows a begs Beatrice to stop. Upon her refusal, Saito draws his sword against her and the dragon knights in her command. The rest of Knights of Ordine join and a battle ensues. Louise is roused from her sleep by the noise from the battle. She then proceeds to end the battle by exploding everyone, including Saito. Later, Tiffania shows up at Saito's bed and ask him to check her breasts to see if he believes they are real. Louise and Siesta show up in time to witness this, and as a result, Louise proceeds to beat Saito with Siesta's approval.

Colbert is alive. He was saved by Tabitha before death. Using knowledge from the dragons plumage he constructed an air ship with an advanced engine. Louise is still suspicious about what she witnessed between Henrietta and Saito and enlists the help of Siesta and Tiffania to capture Saito and force him (by using magic) to reveal what happened the previous night. Pursed across the ship (under the mistaken impression the magic will remove his clothes) by the increasingly desperate trio he is finally cornered and it is revealed to all about Tabitha's involvement in the previous nights escapade. Saito and Henrietta have difficulty meeting each others eyes throughout the episode but the episode concludes with Louise's resolution to trust Saito while Siesta is still concerned.

Using her talents at persuasion, Kirche discover that Tabitha is being held in Al Hambra. Upon arriving in Al Hambra, the gang decide upon a plan of attack. Under the pretext of having a show, they will make the soldiers drink alcohol laced with sleeping potion. When Kirche doesn't assign anything to Louise, she gets angry and demands to be given something to do. Kirche reveals that she knows the Louise is a void mage, and apologises for her past behaivor, and invites her over to Germania. Later on, Derflinger advises Saito to say something to her, saying that Void magic is dependant on emotional strength. Saito decides to do so, and finds her posing in front of a mirror in a dancing costume. Louise begins to tempt Saito, and Saito pushes her onto the bed, but they are interrupted by Guiche. In Tristan, Agnes frees Colbert. She saids that she cannot forgive him for burning her village, but has a chance to end the cycle of hatred that would erupt should she kill Colbert. Back in Al Hambra, the Baron wants Louise to attend to him personally, and she agrees, planning to drug his wine, but discovers that the sleeping potion slipped out of her bra. Saito and Tifa discovers the bottle and go to rescue Louise, Tifa using her magic to wipe the Baron's memories. Having drugged all the soldiers, they encounter Bidashal, who easily defeats all their attacks using Counter. Derflinger tells Louise to cast Dispell on him, which she does, allowing Saito to break through Bidashal's Counter. Tifa stops Saito from killing Bidashal, who tells them where Tabitha is and lets them go, and warns them that Joseph is a cold blooded man, and that it wouldn't end there. Tabitha is awakened by Slyphid, and cries upon seeing the gang, even as Sheffield spies on them using her butterfly.

Saito, Louise, and Tiffania have been summoned to Romalia by his Holiness. They were to meet Julio near the Aquaria’s border, but once there they witness a scene that will affect everyone’s future.

Saito's runes disappear before his, Louise's and Siesta's eyes. While on a trip to the castle, they are attacked by Sheffield, who is revealed to be the familiar of an unseen Void mage that she refers to as "Master Joseph". After arriving at the castle, Saito is given a paper by the princess that would make him a knight and effectively a noble. He, however, turns it down on the issue that he does not believe he can protect the princess or Lousie without the familiar's contract. When asked about the disappearing runes, he tells them about the elf, whom he recalls as Tiffania. Derflinger tells them where they may find her so Louise and Saito prepare to depart. That night while worrying about recent events, Louise awakens to find Saito awake outside on the balcony. She tells him that she is afraid of him leaving again, especially with the disappearance of the runes. He reassures he will not leave despite the absence of any contract. However, when he tries to have sex with her, she blows him up.
