Sasuke's story arc would be completely derailed. Instead of his rivalry with Naruto driving him to become stronger, he might lose his sense of purpose and fall into a deeper darkness. Kakashi would likely be consumed by guilt, which could make him more withdrawn. Hinata might never overcome her shyness as Naruto was a source of her strength and motivation. And the village of Konoha would be in chaos, with many blaming themselves for not protecting Naruto better.
Well, Sasuke's arc would take a very different turn. Without Naruto, he might not have the motivation to constantly strive to be better. He could end up becoming a rogue ninja much earlier, perhaps joining Orochimaru out of a sense of hopelessness. Hinata's arc would be tragic. She might become a shell of her former self, losing the will to improve herself. The village would also lose its future hero. The elders might start to regret their actions towards Naruto, and there would be a power vacuum in the village as Naruto was seen as a potential future leader. This would lead to internal power struggles within Konoha.
The villagers of Konoha would be divided. Some would trust Kakashi and believe there was a good reason for Naruto's death, while others would be furious. The older generation, like Tsunade if she was still around, would demand an investigation. And for Hinata, she would be the most affected. She might feel like she lost her purpose in life with Naruto gone, but then find new strength in seeking justice for him.
Well, for one, Hinata would be completely devastated. She loved Naruto deeply. Her world would crumble. Shikamaru, who respected Naruto's determination, would be angry and confused. Why would Kushina do such a thing? The other Konoha 11 members would also be in a state of disbelief. They had all fought alongside Naruto. Iruka, Naruto's first teacher, would be inconsolable. He had always believed in Naruto and watched him grow. And Jiraiya, if he were still alive in this fanfiction, would be filled with regret for not teaching Naruto more to avoid such a fate.
Regarding his friends, Naruto with Minato's personality would have a different dynamic. His bond with Shikamaru, for instance, would be more about intellectual exchanges. They would probably plan strategies together more smoothly. His relationship with Hinata would also change. Instead of Naruto being the energetic and somewhat clueless one about her feelings, he would be more perceptive. He would pick up on her signals earlier and handle their relationship in a more refined way. And with the other Konoha 11, he would be more of a guiding figure, much like Minato was for his generation.
The other villages might react with a mix of shock and suspicion. They knew Naruto was a powerful force for good in the ninja world. His death could be seen as a sign that something was amiss in Konoha. Some villages might even fear that Konoha was becoming unstable and could pose a threat. Characters like Gaara, who had a special bond with Naruto, would be deeply saddened and might try to find out the real reason behind Naruto's death.
Jiraiya himself would be completely broken. He was Naruto's mentor and had high hopes for him. His actions would likely make him an outcast in the village. Also, the Nine - Tails within Naruto would be a major factor. Its power might go out of control or be lost forever, which could have unforeseen consequences for the balance of power in the Naruto universe.
His relationship with Sasuke would be completely shattered. Sasuke, as an Uchiha, would surely seek revenge against Naruto. This would create a very intense and dark dynamic between them, far from their original friendship.
Sakura's relationship with Sasuke would likely change drastically. With Naruto gone, Sakura might turn to Sasuke even more for support, which could either bring them closer together or cause more friction as Sasuke may not be able to handle her grief. Kakashi, on the other hand, would be deeply affected. He might become more withdrawn, blaming himself for not being able to protect Naruto.
Naruto's optimistic and determined personality would likely make him a fearless Gundam pilot. He'd be the one to always charge forward in battles, inspiring his comrades. His never - give - up attitude would also be an asset in the high - stakes battles of the Gundam Seed universe.
The relationships between the characters might change. If they read about the strong bonds between the characters in Naruto fanfiction, they might strive to improve their own relationships. This could lead to more cooperation among the different factions in Highschool DxD. For example, devils and fallen angels might start to work together more if they are inspired by the teamwork shown in Naruto fanfiction.
Ruby's worldview might expand. She's already a positive - thinking character, but reading about Naruto's journey could reinforce her belief in the power of determination. Naruto overcomes so many obstacles, and Ruby could take that as a sign to keep pushing forward in her fight against the Grimm.
