Poison Mist

Chakra is kneaded within the body and then changed into special chemical substances which is then ejected through the mouth. When this substance comes in contact with the air outside the body, it instantly changes and is transformed into a mist of deadly poison. The poison's ability to kill is tremendous, as even just breathing in a small amount will mean the end of the target's life. As this technique combines ninjutsu, chemistry, and medical knowledge, using it requires fine chakra control and advanced ability in medical ninjutsu.

When used by Ibuse, the gas when inhaled causes the target's body to go numb in a matter of seconds. With the targets paralysed, Hanzō can attack at his leisure. This poison however, must first be generated and stored for five minutes within Ibuse's body before using this technique. This poison is different from the one used by Shizune, as it does not cause instant death.

Trivia

 * In Naruto: Ultimate Ninja 3, almost every character can use this technique by finding a Poison Book for Shizune.
 * In Naruto Shippūden: Ultimate Ninja Storm 3, Hanzō commands Ibuse to use this technique as one of his techniques in the game.
