[Souten no Seigyoku]

Read the chapter. Naruto gains the knowledge of the bunshins when theyre destroyed. So it looks like I was right. The only thing left to cover the plot hole is that Naruto was to dense to realize he was gaining info from his bunshins all this time and needed to have it explained to him. After which he got a slew of bunshin based ideas based on that.

Rasengan Shurikan eh? Looks to me like he couldnt complete the jutsu so he made a poor man's version to tide him over until he finishes it. Maybe he has more wind based goodies.

Definately a good chapter. Helluva cliffhanger.
