Derflinger (ドールフリンゲル?) is Saito's talking sword. It also seems to have the power to warp people, as seen in the start of the third season of Zero no Tsukaima.

Derflinger (nicknamed Derf) was created by the first Gandalfar. It is actually a spirit sword, and upon the destruction of its form, it can transmigrate to a new sword body over a period of weeks. Derf also seems able to absorb magic from attacks cast at it, which it later uses to fuel its various abilities.
