A mysterious group of ninja called the Sora from the Sky Country makes a surprise attack on Konoha. This is because Konoha nearly destroyed the Sky Country during the last Shinobi World War. However, they survived and now are after Konoha and the Fire Country for revenge.
The group starts attacking Konoha, causing mass mayhem, with flying ninjas on winged-mechanical devices bombarding the village. Naruto then appears to help with the battle, until meeting and helping an elder man with a fallen villager. He learns this man is a talented doctor and comes from a neighboring village. The doctor tells him to take the fallen villager to the hospital- then disappears.
At the hospital Hinata and Sakura are both trying to heal the wounded. They begin to talk about how many of the villagers' wounds were previously taken care of before arriving. A boy crashes through the door, looking for his sensei, who is currently in Konoha, that was with him to heal the injured at this village. Naruto comments that he had met the boy's teacher but before he and the boy could talk, he faints in Naruto's arms. Later, Naruto and the old doctor sit beside the boy, named Amaru, and Naruto learns a little of the boy's past.
