"The Familiar's Mark" is the first episode of the third season of The Familiar of Zero.
Saito's runes disappear before his, Louise's and Siesta's eyes, as his death (in season 2, episode 12) caused the runes to fade away. While on a trip to the castle, the three 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. Saito, however, turns it down because he does not believe he can protect the princess or Louise without the familiar's contract that granted him gandalfr abilities. When asked about the disappearing runes, he tells them about the elf, whom he recalls as Tiffania 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 her that he will not leave despite the absence of their contract. However, when he tries to have sex with her, she blows him up.
