Zero no tsukaima F - Season 1 (2012)

Louise and Saito are searching for their Mansion. Meanwhile, Tabitha receives the medicine that will heal her mother, and Queen Henrietta awards Saito an unexpected item.

Louise's sister, Eleanor, shows up as an unexpected visitor and strongly implies that Saito, and Louise by extension, is ruining the House of La Valliere.

A hot spring is discovered on property, Saito decides it's a great time to have a hot springs party. However, an unforeseen guest appears and shocks everyone.

The elemental siblings have returned, catching Saito and Louise off guard. While the battle rages on, a group of very familiar elves arrive and take advantage of the chaos.

With the Ostland flying at max speed to elven land, Saito and Tiffania are put on trial to decide their fate. Will the Ostland make it in time or will war break out?

The Ostland makes it to Reynald, where Tabitha offers to fix the ship. She informs them that she is taking the crown. Louise gets jealous as Saito spends time with Tiffania.

Saito, Louise, and Tiffania have been summoned to Romalia by the Pope. As they wait at the rendezvous point for Julio, they witness a scene that will affect everyone's future.

Julio and Saito's fight with the Ancient Dragon continues, and Saito still refuses to talk about his former partner. Louise must make her toughest decision so far.

Saito ends up trapped in Japan while the fight with the Ancient Dragon rages on. There's no telling if he will make it back to Halkeginia, much less make it in time to help...
