Tornado Rasengan

A-Rank ninjutsu...only Jinchuriki's can use the justu

The user releases a large amount of Demon chakra around them..*similar to naruto's one tail release form*..then the user creates a larger than normal Rasengan allowing it to absorb the demon chakra..the user then compresses the Rasengan locking the Demon chakra inside so that it spins around the core adding power and color to the attack...the more the user can compress the Rasengan the more powerful it will be.
