Alright, B-Ranks then;
Grab onto a sword and mold your wind chakra into it, then as you perform a motion with that sword release the wind chakra from the sword and materialize a strong gust of wind which wraps itsself around you, forming a whirlwind around you which could serve as a defense.
Perform it and list one advantage and one disadvantage, also tell me in what kind of situation you might use it in a fight.
