Background information: I'm not sure if this completely certain in the main canon but here I would be saying how the Rasengan is known to the world and almost every elder shinobi and elder civilian is aware of it (they would be told how the Rasengan and Flying Thunder God are Lord 4th's signature Jutsu). The main people who wouldn't know is younger shinobi (Naruto's generation), who most likely forgot it during the time they learnt about Lord 4th, and would be reminded about it. This is to make it so that everyone would be surprised and shocked to see Naruto to master such a difficult technique created by Lord 4th. I feel like when writing a fanfic it's no so much the action the characters do (me included) that interest people, but more so the reaction and new interactions between characters in new scenarios, that make readers interested and that's what makes people interested.

It was the last round of the Chunin exams, under normal circumstances the gap between the forest of death and the final rounds was 1 month; however with innovations due to technology, Konoha were building a giant screen to record, known as a titantron show and broadcast the finals of the Chiunin Exams. Furthermore it would be recorded with cameras, where it will be shown live and in the moment to every nation in the ninja world.

Right now our protagonist was laying in a hospital bed exhausted. Just recently he was able to prove Gamabunta wrong and was to hang onto his head for hours on end so he could become his minion. Try as Gamabunta might, he could not shake of the Genin. As soon as he woke up he encountered Gaara of the desert who tried to kill Lee. Naruto realises just how similar he and Gaara are. Both had vursed births and both had horrible childhoods, yet Gaara was sadistic, did not value comrades or friendship and wanted to watch the world burn.

Quickly, Naruto was rushing to the Chunin exams stadium. He overslept and didn't want to be late for his fight against the prodigy of the Hyuga clan Neji Hyuga. The odds were stacked against him literally and figuratively as almost everyone had their bets on the pale eyed boy. He getting closer to the stadium when met a a tall man with long white hair.

"Hey Pervy Sage are you gonna see me wipe the floor with Neji?"

"What do you mean?"

"The Chunin exams finals yah know."

"Kid what are talking about. The finals are delayed.

"Huh? What'd you mean."

"They're making some additions and improvements to the stadium. There's still another 3 weeks."

"Really. When I was out for that long time that had me worried." He said with his usual grin.

"Oh we'll see yah around kid." Jiraya was about to leave

"Wait you can't leave, you still have to train me for the finals of the Chunin exams." Naruto pleaded

"What? I don't have to train you kid." Jiraya flustered

"But Kakashi-sensei always plays favourites with Sasuke so he won't train me now." Naruto responded "Okay how about this." As he put his hands together in the cross symbol "Shadow Clone Jutsu" as an army of Naruto's apprear and all in unison shout "Transform." As they turned into a busty lady with long blonde pig tails.

So much blood gushed out of Jiraya's nose, that it caused to him to go flying into the river which the female Naruto's responded with a deadpan expression. "He May be strong, but My God is he pathetic with handling his pervyness."

"Oh yeah baby you got yourself a deal!" Jiraya exclaimed, drowning in the riverwith Naruto earning a sweat drop.

"Awesome. What are you gonna teach me?" Naruto asked

"It will be surprise, and I can promise you that you will love it but pack your things first. We're doing this training outside of the village." Jiraya stated, ignoring how he's soaked.

"Really why?" Naruto asked

"So nobody can spy on us when you are training so they cant think of a strategy to counter this Jutsu. I ain't a spy master for nothing." Jiraya responded proudly.

"Ohhh. That makes total sense. All the more chances to kick Neji's ass during the finals!" Naruto exclaimed

"Great now lets get going."
