The Spiralling Serial Spheres is a double-handed version of the regular Rasengan.
Usage
The user creates two Rasengan, one in each of their hands. The user can then either attack two targets at once,[1] or attack the same target with both Rasengan.[2] When doing so whilst the two Rasengan are spinning in opposite directions against the target, "The counter-rotating spirals interfere with each other in the centre, generating more than twice the power of a Rasengan." (逆回転の螺旋が中央で干渉し合うことで, "螺旋丸"の倍以上の威力が生じる, Gyaku kaiten no rasen ga chūō de kanshō shi au koto de, "Rasengan" no baiijō no iryoku ga shōjiru.)[3]
Senjutsu Influence
Sage Technique: Spiralling Serial Spheres.
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).[4] It is fundamentally the same as the normal version, except stronger.[2]
Trivia
- Jiraiya performed this as a visual aid to teaching Naruto the Rasengan; in one hand he forms a regular Rasengan, and in the other he does within the balloon exercise.[5]
- 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 Ōtsutsuki on the moon, Naruto was shown holding dual Rasengan to block attacks, instead of thrusting them onto the opponent.
