Naruto-rasenshuriken

[Lochy21]

I'm not sure if anyone has posted a thread about this but in chap 611 narutos rasenshuriken has a black ball centre and he is in sage mode. Is this a bijuu dama rasenshuriken or something??

Thoughts anyone? And how powerful do you think this tech will be?

My bad 612****

Kishi might've intended to draw the rotation of chakra with black lines..idk..:shrug:

that's always there, it's the rotation of chakra, it's just the lines got clustered together due to how small it was drawn
