Naruto and Boruto Rasengan Part-4 from Boruto-Naruto Next Generations Episode-65
Boruto-kun is a natural prodigy, being from 2 pioneer families Hyuuga 日向 and Uzumaki 渦巻/うずまき, both being excellent in each paramaeter and one or the other. Where it took Naruto-san months to learn Summoning Jutsu 口寄せの術 and 1 week or so to learn Rasengan (Tsunade-sama staked a bet), it took Boruto-kun less than a week to learn A-rank Jutsu 螺旋丸 Rasengan.
We shall also not forget that he also added Lightning element in Rasengan and created his new jutsu Vanishing Rasengan 消える螺旋丸, which Kakashi-san failed in his prime when he learnt Rasengan from Minato-san. ♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤ Follow my new partner-in-crime @thehokageofanime
