"The Farewell Wedding Ceremony" is the twelfth episode of the second season of The Familiar of Zero.
Louise is secretly approached by one of Henrietta's advisers and is asked to hold the enemy off while the Queen escapes. Knowing that it is a suicide mission, Louise plans to send Saito to safety, but not before marrying him. Catching wind of her plan, Saito uses a sleeping potion on Louise after they wed and asks Julio to take care of her and sets out to meet Albion's advancing troops. Louise faints before she can tell him she has always and still loves him. Despite his valiant efforts, Saito falls on the battlefield. Back at the academy, Louise collapses in grief at Saito's death, however, suddenly the magical flower that is connected to Saito unexpectedly comes back to life. Louise runs out and meets Saito who is very much alive: When Saito fell, the Fairy, who resembles an Elf, saved him, revived him and nursing him back health. While explaining, Saito mentions the fairy's large breasts which then Louise uses as an excuse to fly into a jealous rage, forgets about being sad about him, and starts trying to explode Saito yet again.
