It could be that Konoha wants Naruto to use his influence to bring peace among different clans. Naruto is well - liked and respected, and his words might carry a lot of weight.
Another plot development might be that Konoha asks Naruto to train the next generation of ninjas. Naruto, being the hero of the village, has a lot of skills and knowledge to pass on. He might face challenges in training the newbies, like dealing with their different personalities and abilities, but in the end, he manages to create a strong new generation for Konoha.
Maybe he has some personal grudges against the village. For example, he might have felt betrayed by the village in the past and that made him reluctant to offer help.
Naruto would probably be conflicted. On one hand, he has a deep love for Konoha, his home. But on the other hand, he might have been hurt by the past events that led to his departure. He could initially be hesitant, but eventually be swayed by the thought of seeing his friends again.
One possibility is that Naruto would return with newfound strength and wisdom. He might have learned unique techniques during his time away. Konoha could welcome him with open arms and immediately put his skills to use in protecting the village. For example, he could train the new generation of ninja, sharing his experiences from his travels.
The antagonist could be a new, self - proclaimed ninja god who wants to rule over all the villages. He sees Naruto as the only threat to his power, so he used a powerful spell to take away Naruto's godlike abilities. Konoha wants Naruto back to stop this tyrant. This antagonist might have an army of brainwashed ninja at his command.
One possibility is that Naruto has left Konoha voluntarily after some great tragedy where his godlike powers were misused. Konoha, now in danger again, wants him back. They send out a team of shinobi, including some of his old friends like Sasuke and Sakura. The story could then focus on their journey to convince Naruto to return and help them fight off a group of rogue ninja who are causing chaos with powerful, dark jutsu.
The village would have to rely more on other ninjas. Younger generations like Boruto and his friends would have to step up earlier. This could lead to a different kind of character development for them, as they are forced to take on more responsibilities without Naruto and Hinata's guidance.
Konoha could need Naruto's help in fanfiction to solve internal political problems. His status as a hero could be used to calm down disputes between different clans within the village. Since he is respected by all, he can act as a mediator and bring peace again. For example, if there are disputes over resources or leadership positions, Naruto's influence can be crucial.
