Artemis

The Artemis Rod is Yuki Cross's Anti-vampire Weapon, which she got from Kaien and always wears hidden under her skirt on a leather band. The Artemis Rod is, in its "normal" state, an approximately 20 cm long rod, which can be extended and eventually can turn into a scythe. If vampires touch this weapon, it will react against them with small flashes. For the vampire, this is unpleasant, but they cannot be killed by this. Only when the Artemis Rod is a scythe it is capable of killing vampires.

Yuki left the weapon behind after parting with Zero and leaving Cross Academy in 46th Night. The weapon was left in the custody of the Hunters Association, but was returned to Yuki when Kaname gave it back to her in 57th Night.

Transformation
The first time Yuki picks up the Artemis Rod following her transformation back into a vampire, it tries to reject her, but Yuki persists in spite of warnings from Kaname and it transforms into a scythe.
