Alright it's been a couple of weeks after Naruto left the village with Jiriaya and while the old coot does help out with some of his weaknesses he feels likes his traning is going too slow for his liking. When he and Jiriaya went to sleep in the woods one night he started to rummage through the Jiriaya's bag and he found a small notebook hidden in a secret pocket in the bag which he found with his stupid luck(literally someone should make a story where he and Lady Luck becomes a item or go at it). It turns out it's full of locations for tombs of powerful people even one for the home of the Rikudou Sennin that he wasn't able to go in because of seals. It turns out that there's one nearby at the location where the Third Raikage fought against Iwa's army for three days and three nights to a stand still. There the Third Raikage was buried by the reinforcing army if Kumo when he finally succumbed to his injuries and low amount of Chakra left. Well our favorite blond went there since he thought he could find any powerful artifacts on the Kage to help him have an edge against the Akatsuki. When he finally got to the Third's tomp he found a faint Chakra signature there where he saw the Third's Raikage's wraith(sounds better than ghost) just waiting near his tomp! After a short amount of shouting and fainting it was found out that he(Third) din't feel satisfied in dying without a true legacy where he can implement all his knowledge to. From his "Raiton no Yori" and the secrets of Black Lightning to even how to have your skin become an impenetrable armor, even the Heavanly Transfer Technique if he believed that they're worthy. After a long while of arguing with the old and dead man Naruto was able to convince that he was worthy to become his pupil which would led to him eventually going to Kumo and try to become its Raikage.
Oh and also the pairing has to be Yugito because I just love her! My favorite Kunoichi!
