A mysterious group of ninja from the Land of the Sky made a surprise attack on Konoha. This was because Konoha had nearly destroyed the Land of the Sky during the Second Shinobi World War. The group began attacking Konoha, causing mass mayhem, with Sora-nin flying using a Winged Mechanical Device and bombarding the village. A boy had come a very long way to inform Konoha that his village had been attacked, and that he was looking for his sensei, who was currently in Konoha, so that he could go back with him to heal the injured at his village.
A three-man team, consisting of Naruto, Sakura and Hinata, were sent to accompany the boy, Amaru, and Shinnō, his sensei, to help Amaru’s village. The team travelled through a forest full of eerie beasts and poisonous animals via small rowing boats down a river. A Sora-nin scout suddenly appeared in the sky. Sakura, Hinata and Shinnō hid by the riverside with Naruto and Amaru hiding underwater until the Sora-nin had passed. While underwater, Amaru dropped his scalpel, a present from his beloved sensei, and swam down to get it. As he tried to resurface, he became caught in the reeds. After freeing Amaru from the reeds and helping him back into the boat, Naruto noticed that Amaru was, in fact, a “she”, due to her breasts and corset. Naruto blushed, before a poisonous piranha-like fish bit him and he fainted. Later on, Naruto woke up still blushing, partly because Amaru was sucking the poisonous blood out of the wound on his thigh, thus saving Naruto. Naruto asked her if she was a “she”, and suggested that Amaru had feelings for her sensei, which he was slapped for.
