Artemis

The Artemis Rode is Yuuki Cross's Anti-vampire Weapon, which she got from Kaien and always wears hidden under her skirt at 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 is this unpleasant, but they can't be killed by this. Only when the Artemis Rod is a scythe, it is capable of killing vampires. Yuuki left the weapon behind after the fight with Rido and leaving the Cross Acadamy. The weapon was in the custody of the Hunter Association, but was returned to Yuuki when Kaname gave it back to her in Chapter 57.

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.
