Kanashimi

Kanashimi wears a black Kitsune mask, with hot pink markings all over that have a faint glow. Though this is no ordinary mask. It is cursed, and cannot be remove by any possible means. The mask can take over Kanashimi at it's will, causing him to act aggressive and devious when in control. This includes the feeling of Anger, Sadness, Tendencies to commit crime and murder, as well as other varieties of emotions and acts that cannot be prevented during these times of control the mask possesses. Once Kanashimi gains control of himself, he will feel deep regret of his actions and shut himself away for a while, especially if he committed a bad crime.

The mask prevents Kanashimi from growing in any way, this includes height, age, and it also prevents death. Although he is unable to die, he can still feel everything someone would feel before death. For instance, cutting his leg off wouldn't kill him, rather just make him suffer by extreme amounts of pain before it regrows itself back. (limb healing would take somewhere between 1-3 weeks of complete regeneration.)
