Artemis

Yuki Cross's magical anti-vampire weapon. When touched or wielded by vampires, it will react against them. It normally compacts into a short rod and extends when Yuki uses it in battle. Yuki carries it hidden under her uniform strapped to her thigh.

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

Trivia

 * Kaname carries the Artemis Scythe on the cover of Volume 2.

Questions

 * Does the weapon still compact as did when it was still a rod?
 * Does the scythe reverts to its original rod form when Yuki is not in battle?
