In this fanfiction, Jiraiya and Pain are the main characters in the fight. But from Konoha's side, Naruto is a very important one. His emotions for Jiraiya would be running high. Then there's Sakura, who is not only a skilled medic - ninja but also cares about the safety of the village. She would be worried about the outcome. And don't forget about the elders in Konoha. Their opinions and reactions to the fight would also play a part in the overall story of this fanfiction.
Well, you can expect a lot of intense emotions. Konoha characters would be on the edge of their seats, seeing Jiraiya fight Pain. There might be shock at Jiraiya's skills and the power of Pain's attacks. They could also be filled with pride for Jiraiya or fear for his safety. And of course, there would be a lot of reactions to the twists and turns in the fight, like gasps when Jiraiya makes a risky move or when Pain reveals a new jutsu.
The plot should be engaging. It could add new twists to the Naruto vs Pain battle. Maybe introduce some new jutsus or strategies that make the fight even more exciting. Also, good fanfictions in this category usually have a good balance between action and the emotional aspects of the characters.
The outcome in this fanfiction could be a draw. Naruto and Hinata would put up a great fight against Pain. Naruto would be all fired up, using his Rasengan and other ninjutsu. Hinata would be there, protecting Naruto's blind spots with her gentle fist techniques. But Pain is no pushover. His ability to control gravity and rain down destruction could keep Naruto and Hinata at bay, leading to a situation where neither side can fully defeat the other.
One possible reason could be that Naruto feels he has learned all he can from Jiraiya at that point. Maybe he wants to explore his own path independently and test his skills without Jiraiya's constant guidance.
It can create a sense of growth for Naruto. Without Jiraiya by his side, he has to rely more on his own instincts and the skills he has already acquired. This can lead to new character development as he faces challenges alone.
One possible reason could be that in this fanfiction, Jiraiya might be preoccupied with other important matters. Maybe he has a secret mission that demands his full attention and he simply doesn't have the time to train Naruto. Another reason could be that there is some sort of conflict or misunderstanding between them that prevents Jiraiya from taking Naruto under his wing. For example, Naruto might have unknowingly offended Jiraiya in some way, or there could be a prophecy or external force that is keeping them apart for the time being.
You can try some popular fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a large collection of Naruto fanfictions, including ones about Naruto vs Pain.
One possible plot twist could be that Hinata discovers a new power within herself during the fight against Pain. Maybe she can tap into some ancient Hyuga ability that even she didn't know existed. This new power could turn the tide of the battle and surprise both Naruto and Pain.
In fanfiction, Jiraiya seeing Naruto as Hokage can be a very emotional moment. It could be a vision Jiraiya has in a story where he's still alive, or perhaps it's a memory in a story set after his death. This often shows Jiraiya's pride in Naruto and his belief in Naruto's potential to lead the village.
