Users Class: Weapons Class
The Range of the weapon: In default form - the spike and hilt are 2 feet long, the chain is approximately 8 feet long, the loop has a 6 inch diameter.
Weakness: Weakened and easily deflected by Fuuton jutsu, can become dull, fragile, etc... If Maro's mental state deteriorates.
Description: Oni is Maro's key and it takes the shape of a plain spike attached by a chain to a loop. It's physical properties are close to that of a non-ferrous metal, meaning it can conduct heat/cold/electricity and is reflective. Being Maro's key, Oni is highly resistant to lightning based jutsu because his nature is Raiton, also Oni will not conduct electricity originating from any source other then Maro. Also Because Oni is Maro's key, he is able to control and manipulate the weapon without even touching it. For unknown reasons, Oni rejects being coated in poison and thus can not used with poison that the assassins-nin are known for.
