Wind Release: Spiralling Shuriken
Wind Release: Rasenshuriken (風遁・螺旋手裏剣, Fūton: Rasenshuriken) is a wind-based ninjutsu invented by Naruto. It is done by mixing wind chakra into the Rasengan and form it into four large points, causing the Rasengan to take on the appearance of a fūma shuriken, with the Rasengan in the centre remaining a perfect sphere.
After colliding with a target, the central sphere of the Rasenshuriken detonates, producing a vortex of wind in the immediate area.
Naruto later improved the Rasenshuriken with Sage Mode. This allows him to throw it at his opponents, and removes the restrictions of having to get in close-range of his opponent. The shuriken can also expand after it has been thrown, compensating for imprecise aim or fleeing opponents by widening the area of effect.
