Well, one possible plot could be that Naruto is forced back due to a new threat emerging in Konoha that only he can help with. Maybe an old enemy has resurfaced and the village elders believe Naruto's power is essential to combat it.
The village elders are very likely to be involved. They often have a say in the big decisions in Konoha. They might be the ones who decide that Naruto must return for the safety or the benefit of the village. Tsunade could also be a part of it. If she's still in charge, she might be in a difficult position of having to order Naruto back or deal with the consequences of his forced return.
Well, one possible plot could be that Naruto is on a very important mission far from Konoha. But due to some political reasons, like the village elders fearing he might defect or get influenced by outside forces, they force him to return. For example, they might spread false rumors about him being in danger or that he's needed urgently for some made - up security reason.
One possible reason could be false accusations against him. Maybe he's wrongly blamed for a crime he didn't commit, like being framed for a major attack in the village. This would lead the village leaders to force him out to maintain 'peace' and security.
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 possible reason could be a new threat to Konoha that only Naruto has the power to face. For example, a powerful enemy has emerged and the village elders believe Naruto's strength is essential for the village's defense.
A new character could be introduced as the main antagonist. Maybe a powerful ninja from another village who has infiltrated Konoha's politics. This character could be the one behind the idea of forcing Naruto back, with the intention of using Naruto as a pawn in a larger scheme against Konoha.
It could be the village elders. They often make decisions for the benefit of the village as they see it. They might think Naruto is needed back in Konoha to deal with potential threats or to boost the morale of the villagers.
As he is forced to leave, Naruto may become more cautious. In Konoha, he had some level of protection, but now on his own, he has to be more aware of his surroundings. This could also make him more empathetic towards outcasts, as he is now in a similar situation. His ninja skills might also improve faster as he has to rely solely on himself in battles and difficult situations.
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.
