Humanity Nullification Technique

The Humanity Nullification Technique is a unique kinjutsu developed by Nigihayami after synthesizing several of Orochimaru's research experiments, in an effect to reverse the effects of a strange gas upon his own body. He later began to use it in combat, after he discovered that its effects would plague him at random times if he did not willingly activate it in battle. This technique halts all pain that the user feels, and if he uses it on a greater scale, all sensation as well, using his chakra sensory skills to discover whether he has made contact with something. This makes him a very highly formidable opponent, because while he may take serious or even life-threatening injuries, he feels nothing, and is able to continue fighting even if he loses a limb. This also lets him overcome any fear of injury, so that he can fight without inhibition, demonstrating far greater destructive power while using this technique. Feelings such as anxiety or excitement, that impede judgment, as well as remorse or guilt, are also removed by this technique, facilitating better combative skills, but at the price of becoming a monster, and the actual personality of the user is slowly dulled over time as well.
