Some in the village would be sad to see them go. Naruto is a hero to many, and Hinata is also well - liked. People like Iruka would miss Naruto a great deal. But others might understand their need for a new life away from the village and support their decision.
The village elders might be worried at first. Naruto has been a key figure in Konoha's security. His departure could leave a gap in the village's defenses. However, they also know that Naruto has given a lot to the village already. Hinata's family, the Hyuga clan, might be proud of her for following her heart and starting a new adventure with Naruto, but also a bit concerned about her leaving the safety of the clan in Konoha.
The younger generation of ninjas in Konoha would see Naruto and Hinata's departure as an inspiration. They would think that there is a whole world out there to explore and that they don't have to be tied down to just Konoha. It could also lead to some of them wanting to go on their own journeys in the future, to seek their own paths like Naruto and Hinata are doing.
Kiba would probably be shocked. He's Naruto's friend and also has a connection to Hinata. He might try to convince them to stay, saying things like Konoha needs them. But once he realizes they are determined, he would support them in his own way, like promising to visit them. As for Lee, he would see it as a very brave decision. He would be inspired by their courage to step out of their comfort zone and start a new life elsewhere.
Perhaps they are leaving together to search for a cure for some new and dangerous disease that has started to affect ninjas. They believe that by traveling the world, they will find rare herbs or meet wise sages who can help them develop a remedy. Naruto's determination and Hinata's knowledge of medicinal plants could be a great combination for this noble quest.
The villagers would likely be shocked. Naruto is a hero to many in Konoha, and Tsunade is the Hokage. Their sudden departure would cause a great deal of confusion and concern. Some might think that Konoha is in danger if two such important figures have left.
They could leave because of a prophecy. Some ancient prophecy might state that they need to leave Konoha to fulfill a greater destiny elsewhere. So they trust in this prophecy and leave their home.
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.
One possible reason could be to seek a new life away from the politics and pressures of Konoha. Maybe they feel restricted by the village's rules and expectations. Another reason might be for a personal adventure. They could be in search of something that Konoha can't offer, like a new type of ninja training or a mysterious power source. Also, it could be related to protecting their family. If they sense some kind of threat to their family within Konoha, they might choose to leave to keep them safe.
Sakura might be initially shocked and heartbroken. She has been Naruto's friend for a long time, and his sudden departure would leave a big hole in her life. She might try to convince him to stay at first.
Hinata would be heartbroken at first. Naruto is someone she deeply cares about. But she's also a strong - willed ninja. So she might start by trying to understand why Naruto left. She could look for clues in the village or talk to Naruto's friends to figure out his possible destination.
Naruto would probably be very angry at first. He has always considered Konoha his home and to be betrayed by it would be a huge blow. He might initially try to reason with the villagers, thinking it's a misunderstanding. Hinata, on the other hand, would be more likely to be heartbroken. She's more reserved and the thought of her village turning against her would be deeply painful.
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.
