Gaseous Genjutsu: Oni Steam

One of the Jutsu's that made Saru Konton famous, this Genjutsu is feared by many, including Susaisu Hatake. As a 'Gaseous' Genjutsu, the Genjutsu is cast via some sort of gas, and in Saru's case, this Genjutsu is cast via dust.

The user must cast the Genjutsu via their gas medium, and must make contact with the target(s). Immediately, their vision will blur, and will feel as if their worst nightmares have manifested into an Oni, which then proceeds to use the nightmares as attacks.

It may not be a 'physical' Genjutsu, but it is a powerful one.

After use, the target(s) is rarely able to stand on their feet, as fear flows through them, and they are in shock.
