Description: Lately, Komizu has noticed just how well he can control his Fuuton element. The thought of complete control excited him, which resulted in the creation of this skill. After multiple trials and errors he had finally mastered controlling the air...

Fuuton Mastery is a skill in which the user can completely manipulate the air around them. Without the use of hand signs, they can either release it from their mouth or other body parts. The user is immune to their own fuuton. Wind can't be manipulated unless it's within the user's range (Ranges are stated above).


Requirements:
-Wind must be first element
-Have Komizu's OOC permission or learn from Komizu.

Instead of saying that people can't use Wind against you just make it that you've increased your durability against it. So it's not really going to harm you as much. Also, how would SS-Rank Wind techniques do against you?
