Hm. Interesting idea. However on this site you do not have to expend actual reiatsu to utilize hohō, which is the exact ability you were referring to. Therefore I wonder if you believe this style would be worthwhile? I can't think of a situation in which your character, or any other's, would not be able to use hoho to get leverage in the air. From reading this style, I would assume you want to prevent a situation in which your character would be unable to react to certain threats when in free fall, hence the name I suppose. However since I can't think of a situation in which any character besides perhaps a human character would be unable to fight efficiently in free-fall, I don't know if it has any purpose in this rpg.
That said I do like the originality shown, and it does make sense. I also understand why you would want something like this for your character. Read up on the systems and figure out whether something like this is absolutely necessary. If you still believe it is necessary know that this move only applies to your character and you should not expect the principals you've outlined here apply to other characters unless they learn the style as well. In addition, I see no reason why you should have to type so many words to learn this. You may reduce the word count if you want.
