Death or Knockout
Fight takes place in The Rocky Mountains
You forget that in the latest chapter tsuna surpass his current flv. After being shot by the dying bullet after he was in hyper mode surpassing yet again reborns expectations again. Then defeating the leader of the vendenci bermuda who made the flame of the night. He didn't even need his vongola gear to beat him after being released to next level. If he were to use the vongola gear with natsu he would probably equal the speed output of goku in super sayan 3. Since Naruto can only fight ground battle and not sky and speed. Tsuna has it in the bag. Also lastly if he were to borrow the shimon ring of gravity like the battle with david spade. He would beat naruto in less than a minute or less with all that power.
@taichokage dude you keep forgetting that tsuan can't use dying will point break through on naruto since he doesn't use the dying will flame. The only way that naruto has a chance of being frozen is if which a big "if" Tsuna used double XX Burner at full gauge which would pass 500,000,00 FV. Then freezing the flame in mid fire in casing naruto in tomb of ice that can not destroyed or melted unless some one use a higher flame then Tsuna. Even with out the dying will point break through tsuna can just charge his globes and add natsu then use Vongola primo ultimate attack with the charge and send naruto to hell.
