Fire Release: Suicidal Rebirth Flash

A technique designed for defense as well as deception, the Suicidal Rebirth Flash is a highly dangerous technique and is regarded as a forbidden jutsu due to its danger to the user.

The technique involves using fire release chakra in order to ignite the air around the user, with a thin layer of chakra to protect the user. The technique works by rapidly depleting the oxygen around the user, chocking out any flames from reaching the user; due to the speed at which this occurs, as well as the flames produced, makes the attack appear to have hit, however when the flames die down it will be revealed that the user survived, giving the impression that the user is fire proof.

Weaknesses
If the user becomes over taxed and attempts to use this technique, then it's quite possible for the layer of chakra protecting the user to either fail or ignite as well, thus making the technique a true suicide move by burning the user to ash.
