Demonic Mask
A mask bound to Mishikama by a now dead priestess. Mishikama's only goal in life is to have someone remove the mask. This mask has a personality of it's own that takes control whenever Mishikama is around someone. The mask has the ability to sense a life forms, life force no matter how small or hidden it may be. As such, when one weaker than Mishikama comes along, the mask takes control, and swiftly uses Mishikama's body to slay it, absorbing and feasting on it;s soul to grow the Kaze Katana and itself in power.
Kaze Katana
Literally the Air Katana. This weapon harnesses Mishikama and the Demonic Masks charka and power and uses it for various attacks in the Gale Style. When in use the weapon gives off a pale green aura. the weapon was originally sealed inside a shrine in the village he slaughtered, but was soon taken by the Demonic Mask controlling Mishikama.
Ude Mokuzai
Literally: Wooden Arm. The Wooden Arm is the only part of Mishikama that can hold the power of the Kaze Katana without it taking control over him and in turn the Demonic Mask. The demonic mask knew this, and upon taking control of the first time, ripped the right arm of Mishikama off and replaced it with a wooden prosthetic.
