Another way Naruto could react is by trying to avoid Tsunade. He might think he's done something wrong and is in trouble, so he'll start taking different routes, being more secretive about his activities. But as he does this, it could make Tsunade even more determined to stalk him. And eventually, when the truth comes out, there could be a big emotional moment between them, either of relief or of anger depending on how it's all handled.
Naruto would be deeply hurt. He would probably feel a mix of anger and sadness. At first, he might try to reason with Tsunade, to find out why she betrayed him.
Well, it could be a really wild plot. Maybe Tsunade has some strange reasons for stalking Naruto in the fanfic. It might be that she suspects Naruto of having some hidden power or connection that she needs to figure out for the safety of the village. Or perhaps it's a case of misinformation and she thinks Naruto is involved in something he's not.
The reaction would be one of shock. Naruto is a well - known figure in the ninja world, and many see him as a symbol of hope. His friends like Sakura and Sasuke would be devastated. Sakura, who has known Naruto for a long time, would likely be in disbelief and filled with anger towards Tsunade. Sasuke, depending on his state in the fanfic, might seek revenge.
He would probably also feel angry. After all, he has sacrificed so much for the village and for them. He might start to question his own beliefs and values. But Naruto being Naruto, he would not give up easily. He would try to prove his innocence and show them that they are wrong. He could go on a journey to find evidence or seek help from other allies who still believe in him, like Shikamaru or Kakashi.
Tsunade could be a bit flustered at first. After all, she is a tough - as - nails leader, and a hug from Naruto, who she has watched grow up, might make her feel a bit vulnerable in a good way. She might then relax and even give Naruto a pat on the back in return, showing her appreciation for the gesture.
Naruto could also become angry. He might feel betrayed by Tsunade and the village. This anger could fuel his determination to prove his innocence or worth. He could set out on a journey to become even stronger, so that one day he could return and show everyone that they were wrong to banish him. He might also start to question his own beliefs and values, which have been centered around the village and its people.
The other kages from different villages would also have reactions. Gaara, being Naruto's friend, would be happy for him and send a grand gift. The Raikage might be a bit surprised but would respect their decision. The Mizukage would probably see it as an interesting development in the relationships between the ninja villages. All in all, the reactions would range from shock to joy, but in the end, most would support the union.
At first, Naruto would probably be excited. He's always eager to get stronger, so he might see this as an opportunity. He'd trust Tsunade because she's the Hokage and a respected medical ninja. But if the experiments got too painful or started to seem strange, he'd start to question things. He might try to talk to Tsunade about it, but in his Naruto - like way, still be respectful.
If Tsunade hurts Naruto, it could cause Naruto to become more distant from her. He might avoid her, and this could have an impact on the village as well. Tsunade, on her part, would probably feel a great deal of guilt. This guilt could make her try to make amends, but Naruto may not be so quick to forgive. Their relationship would be in a state of flux, with Tsunade trying to regain Naruto's trust and Naruto trying to come to terms with what happened.
Tsunade would probably be very suspicious at first. Naruto suddenly appearing from the future? It's not something that happens every day. She might think it's some kind of enemy's trick or a genjutsu.
