Well, Naruto kind-of-lost his hope and tried to break the seal that the 4th Hokage gave to him. After the 8th tail of the demon fox appeared, the 4th hokage were able to come back to stop Naruto.
He then told him that he is his son and that he must not try to break the seal for it might cause much trouble for Konoha. He told him that the masked-Akatsuki member is the one that is controlling Pain and the one that is responsible why the Fox attacked the Konoha sixteen years ago.
Before disapperaing, Minato, strengthen the seal again and told Naruto that he must do everything to stop Pain in a manner that he believes for there is still hope that Konoha can be rebuilt.
The manga episode ended upon the disapperanace of the demon fox…and Naruto is ready to face and fight Pain, no matter what may happen…
-as if I care about your opinion...-
