Mark my words NB'ers. This is coming very soon. We've seen one handed mini-rasenshuriken in KCM. We've seen one handed rasengan in SM. The one handed thrown rasenshuriken is coming in BSM. Mark my words! :naruto:
I agree it would be a true testament to how far naruto has come,
and for those who say he's done it already or it wont be anything special then u bothr wrong,
right now he physically uses one hand to do one but he uses a 2 chakra cloak hands in the place of a shadow clone now, which means he can do a rasengan now with no trouble now ever since the fox isn't playing around with naruto's chakra network like for the most of the series.
also it will be a big deal to do a real one handed wind rasengan as then he would be able to do multiple(like 6) wind rasnegans which his chakra cloak hands like he did with the rasengan at the start of the war.
And u can mark those words, right there.
But in my opinion the next attack we will see from naruto is a wind bjuudama, and will be the most powerful attack in the series.
