Rasengan

Rasengan - Spiral Sphere
Rank: A

Type: Ninjutsu

Prerequisite: Konoha-nin

The technique is unlike other jutsu in that it does not require any handseals, it just relied on the ninja's ability to mold chakra. The ninja concentrates a contained, fast, rotating sphere of chakra in the palm of their hand which can cause much destructive impact. Thus the technique was pure shape manipulation of chakra, unlike most elemental techniques which are shape and nature manipulation.
