The Spiralling Serial Spheres is a double-handed version of the regular Rasengan.
When in Sage Mode, the user can use a senjutsu-enhanced version known as Sage Technique: Spiralling Serial Spheres (仙術・螺旋連丸, Senjutsu: Rasenrengan, English TV: Sage Jutsu: Rasengan Barrage). It is fundamentally the same as the normal version, except stronger.
- Jiraiya does something similar when he teaches Naruto how to use the Rasengan; in one hand he forms a regular Rasengan, and in the other he does the balloon exercise.
- When Naruto performs this technique in Naruto the Movie: Legend of the Stone of Gelel, he uses two different versions of the Rasengan: the Gelel Rasengan and the Demon Fox Rasengan. In this movie, he calls it "Twin Rasengan" (ツイン螺旋丸, Tsuin Rasengan, Literally meaning: Twin Spiralling Spheres).
- In The Last: Naruto the Movie, in his fight against Toneri on the moon, Naruto was shown holding dual Rasengan to block attacks, instead of thrusting them onto the opponent.
