Koenig's Nebbia Numero Quattro (lit. Mist Number Four) of the Armatura Series is a Box Weapon for anti- use. In other words, it was created under the assumption of countering its own Mist-attribute. It cannot defend against physical attacks, but the magic stones embedded all over the armor are said to enhance the power of illusions. It is an item that any illusionist would like to adorn, but its use demands great ability.
