Description: Greis (Old Man) is a dirty white old marten. His eyes are white from blindness and his ears are deaf from old battle wounds. Despite those weaknesses, Greis is a calm and wise marten. He usually speaks very slowly.
His greatest (And only) ability is a powerful inhalation-induced Longe Ranged Genjutsu - Greis chakra his released from his body like odour and inserts itself on the target's brain through the mouth or the nose. The Genjutsu its constant and, every turn, Greis looses 30 chakra (He can only stay in the battlefield for 4 turns). The foreign chakra stimulates the area of the brain responsible for dealing with pain, thus it will make the hosts will experience increasing levels of pain/burning sensation inside the breathing pipes, lungs and digestive pipes down to the loins. Depending on the quantity inhaled, the severity of said pain varies, so the rank of the victim will determine the ammount of exposure to the genjutsu necessariy for it to translate in full loss of consciousness.
Special Jounin - Roughly 1 turn
S-Class - Roughly 2 turns
Sannin - Roughly 3 turns
Kage - Roughly 4 turns (Greis' already out of play)
Sages - Roughly 5 turns (Greis' already out of play)
To release the Genjutsu, on must either vanish Greis, or have a constant supply of allied foreign chakra, constantly repressing the genjutsu for as long as Greis' in play (Even if both are affected by the Genjutsu, they can release eachother). Momentary repressions of the Genjutsu will lessen the pain, but are irrelevant to the effects described earlier. This only applies when Greis' in play, because there's a constant source of chakra to keep the Genjutsu. After the 4 turns, when Greis vanishes, any normal ways to release A ranked Genjutsus are fair game.
