Name of Jutsu: Futton: Kōmu no Jutsu (Boil Release: Skilled Mist Technique)
Rank: B
Range: 20 Meters
Handseals: Horse
Effect: The user creates a cloud of mist which he releases from his mouth. This mist has corrosive properties, capable of even melting the bones of the Susanoo. The technique has an inherent disadvantage in that its effects are indiscriminate, limiting its usage to areas that do not presently contain allies until the attack is completed. In the event that the mist escapes the containment area, thus putting others in danger, the user can sufficiently manipulate its acidic qualities to safer levels by adjusting the pH levels of the mist.
Though the mist is corrosive to all around it, the user is immune to it, as Mei used it in an enclosed area without endangering herself.
Weaknesses: The mist will still conduct Raiton attacks, though the damage from such attacks is halved.
