Following Saito's heroic actions in the War with Albion in season two, Saito & Louise return to Tristain, only to have the runes which bind Saito & Louise disappear. Saito & Louise struggle with a relationship no longer defined as Master & Familiar, as they search for an Elf who has the power to restore the dead to life, and may hold the key to understanding Saito's loss of the Gandalfr's power.
This series is a lot of fun and a great idea. I really enjoyed this series of zero no tsukaima, it was great to see the writers introduce new characters and bring depth to already introduced ones, and hope to see more development of the characters in season 4!!
