Talk no Jutsu does a Fist of the North Star Tower

Naruto Uzumaki from...let's say, KCM1 (because EofS is too much)

Is in the Hokuto no Ken Universe, and encounters the same enemies Kenshiro does, but rather than fighting them (because that's no fun), has to Talk no Jutsu them out of their evil ways. Naruto has full knowledge of their backgrounds up until Round 5. He gets to keep any knowledge he picks up from each fight. If he has to use any lethal attack, he loses the fight (because winning is not the goal). Antagonists and villains are in-character.

Rounds:

1) Zeed (this is the only round Naruto can fight to the end)

2) Shin

3) Jagi

4) Raoh

5) Souther (Shuu can help this round)

6) Hyoh

7) Kaioh (If Naruto gets this far, Hyoh can help this round)

Where does he stop and why?
