What does Naruto do after he kills pein?

Answer 1

Depends on which pein, like Nagato or the one that almost killed Hinata.

After Naruto kills the pein who almost killed Hinata, he leaves to find the person who controls the 6 paths of pien. He finds Nagato, the controler, in a tree made of paper. He confronts Nagato and tells him how much he hates him and that he was also Jiraya's student. After listening to Naruto, Nagato decides to use his remaining power to restore all the lives of the shinobi who died in Konoha during the battle. Naruto leaves and sets up a small shrine for Jiraya before heading back to the village. When he arrives, everyone is there to greet him and express their thanks. The episode ends with all of Naruto's friends begin throwing him in the air in celebration.
