One-of-a-Kind All-Purpose Tornado Technique

The One-of-a-Kind All-Purpose Tornado Technique, is Kasai Uchiha's signature technique. Originally created as a Genin, it had no real practical use instead being used simply to create miniature tornadoes in her hand to alleviate boredom. However with some help from her teacher, Kasai was able to turn it into a deadly technique capable of immense destruction. Solely dependant on how much chakra the user expended, this technique is capable of creating gigantic tornadoes capable of ripping apart several ships at once, rip through fortifications and even destroy an entire village. Of course it can be shrunk in order to effect areas on a more grounded level such as a team of enemy shinobi, or even a single opponent.
