Iburi Clan's Kekkei Genkai

As the unique kekkei genkai of the members of the Iburi clan, the user can turn their body into smoke. Even in their smoke form, they're capable of interacting with physical objects. Initially, the clan members did not have complete control over the technique, causing them to sometimes transform into smoke without intending to do so. Their ability was partially stabilised, however, through the application of one of Orochimaru's cursed seals on each clan member. While in their smoke form, they are vulnerable to wind, as dispersion while in their smoke form is fatal.
