One possible reason could be a misunderstanding. Maybe Tsunade received some false information about Naruto that made her think he was a threat to the village, so she took actions that ended up hurting him.
Perhaps he would seek out other powerful ninjas for help. Jiraiya, if he was still alive in the fanfiction, could teach Naruto some new techniques to not only heal his physical wounds but also strengthen his mental state. Or he could go to Kakashi, who has a deep understanding of Naruto and could give him advice on how to deal with the situation.
One possible scenario could be during a training session. Tsunade, known for her tough training methods, might accidentally go too far and physically harm Naruto while trying to push him to his limits. For example, she could miscalculate the force of a punch during a sparring exercise.
She could physically harm him. Maybe in a fit of anger, she punches or uses her strength on Jiraiya. Since Tsunade is known for her powerful physical attacks, it would be a likely way for her to hurt him. Another way is through emotional harm. She could reject Jiraiya's feelings for her in a very cruel way, saying things that cut deep into his self - esteem and his love for her.
There could be. Fanfiction writers often come up with all sorts of interesting and unexpected relationships in their works. Given that both Naruto and Tsunade are important characters in the Naruto universe, a writer might have decided to create a story where Naruto is Tsunade's grandchild to explore new storylines, character development, and the impact on the existing Naruto world. It would likely involve a lot of creativity in terms of how their relationship affects the plot, the other characters, and the overarching themes of the Naruto story.
If Tsunade kisses Naruto, it could strengthen their relationship in a mentor - like way. Naruto might see it as a sign of deep respect and trust from Tsunade. He would likely feel more confident in following her guidance. For Tsunade, it could be a way of showing her pride in Naruto's growth.
Well, it could develop through shared experiences. For instance, if they both go on a diplomatic mission to another village. During the journey, they face difficulties like hostile ninja attacks or harsh weather. They have to rely on each other's skills. Naruto's combat skills and Tsunade's strategic thinking complement each other. This cooperation makes them closer and over time, love might bloom between them.
Naruto might be initially confused. He trusts Tsunade, so being kidnapped by her would be completely unexpected. He would probably start by asking her why she's doing this.
There may be some dark or alternate universe fanfictions out there with such a plot, but it goes against the general nature of the Naruto series. Naruto is more about friendship and growth, not about killing main characters like Tsunade in a random way.
A fanfiction could be set where Tsunade tasks Hinata with protecting Naruto during a dangerous political summit. Hinata, being very loyal to Naruto, takes on the role with great seriousness. She uses her gentle fist techniques in creative ways to fend off any threats. This experience could bring Naruto and Hinata closer together while also earning Hinata respect from Tsunade.
