Socially, there would be a lot of unrest. Naruto has friends and supporters all over Konoha. His departure would cause a rift among the villagers. Some might blame the village leadership for driving him away, while others might try to find ways to bring him back.
Konoha's power structure could be affected. Naruto is one of the strongest shinobi in the village. Without him, the village might be more vulnerable to attacks from other villages or threats. They would need to quickly find ways to fill the gap in their defenses.
It could lead to political unrest in Konoha. There might be those who blame the village leadership for Naruto's departure. This could lead to power struggles as different factions try to take control and change the way the village is run. Some might demand more transparency and better treatment of their shinobi to prevent such a thing from happening again.
It could create a sense of unease and fear. Naruto is a very powerful ninja, and if he turns dark and leaves, the villagers would be worried about him coming back as an enemy. It might also lead to a decrease in morale among the ninjas who once considered Naruto a friend or ally.
Sakura would be heartbroken. She has deep feelings for Naruto, and his sudden departure would make her feel abandoned. She might initially be angry at him for leaving without saying goodbye but would soon worry about his safety.
It would create a sense of panic. Naruto is a very important figure in Konoha. His strength has been crucial in protecting the village. Without him, the villagers would fear attacks from other villages or threats from the Akatsuki. For instance, if the Akatsuki knew Naruto had left Konoha, they would likely see it as an opportunity to capture him more easily.
It would be a huge blow to Konoha. Naruto is a hero in the village, and his departure would leave a big leadership void. The villagers would also lose a great source of inspiration. Hinata is from a respected clan, and her leaving would also have an impact on the clan's standing in the village. Morale among the ninjas might drop as they see two important figures leave.
For Naruto, it would be a big shock. He's always seen Sakura as an important part of the team. He would probably feel guilty, thinking he might have done something wrong. Sasuke might be more reserved in his reaction, but deep down, he would also feel the loss. Kakashi would be worried about her safety. The other ninja in Konoha might start to question the unity of the village if someone like Sakura, who was so well - known, left. And the young ninja who looked up to Sakura would be disappointed and might even lose some motivation in their training.
His friends would be worried. Sakura might be very concerned about his safety and feel sad that he left. She may also feel guilty if she thinks she could have done something to prevent his departure.
However, it could also force Konoha to reevaluate its treatment of its ninjas. Maybe they would realize that they need to be more inclusive and less self - serving in their actions. This could lead to some positive changes in the long run, such as better treatment of Jinchurikis and other marginalized ninja groups.
Economically, there could be some impact as well. Naruto and Hinata are popular figures, and their presence in Konoha likely contributed to the local economy in some ways, such as through tourism (people coming to see the famous Naruto). Their departure might cause a dip in certain sectors that relied on their popularity, but it could also open up opportunities for new shinobi to rise and bring in new sources of income for the village.
Kakashi would be worried. He has always been a mentor to Naruto. His departure would make Kakashi feel like he failed in some way. He would probably try to find Naruto to bring him back or at least make sure he's okay. The rest of the Konoha 11 would also be affected. They would miss Naruto's presence and some might even question the village's decision (if there was one) that led to Naruto leaving.
