Keiko Personal Justu

[Keiko]

Technique Name:

Futtou Iki no Jutsu | Boiling Breath Technique

Availability: Personal
Prerequisites: Suiton, Katon
Rank: D-S
Type: Ninjutsu
Chakra Nature: Futton
Description:

This is a ninjutsu that is always active, regardless of whether or not Keiko is in combat. This peculiar ninjutsu is permanently implanted into Keiko's throat, and constantly converts Suiton and Katon chakra into Futton chakra that pours out of his breath, generating a constant stream of corrosive mist. This mist, in high concentrations, can melt through most objects - however, it typically isn't that powerful on its own. What makes it effective is the fact that the chakra remains in the air, and over some time (undetermined, as it is faster in closed spaces and at higher user levels - a Jonin would be able to generate more than a Genin), the chakra can build up and accumulate into a larger cloud of corrosive gas, although Keiko is completely unaffected by it. Keiko is the only known applicant of this experimental technique, and there doesn't seem to be a way to variate or regulate it, it is merely always in use, much like the Aburame's Kikaichu no Jutsu, and is something that will stick with Keiko for the rest of his life.

Generation of the mist will stop when his Chakra reserves become dangerously low, however that rarely happens and he is bound to pass-out before it does, as the actual chakra consumption is incredibly miniscule. However, one can force more chakra into the technique to speed the production up, but it is typically not expected at lower shinobi ranks, nor is it encouraged as putting too much into the technique may induce dizziness and fatigue.

The technique can be limited, however - by simply holding one's breath or keeping one's mouth shut, the chakra has no method of escaping the user's body and will simply recirculate back into their chakra system, however no mist will be created until they open their mouth again. The mist cannot travel through the user's nose.

You would need to give this a rank of D-S to allow for figuring out the chakra consumption per post it's in use; the highest level of use would, of course, be the level of your futton ninjutsu. Other than that, this looks fine, and quite interesting!
