Another plot twist could be that the situation Tsunade is in is actually a trap set by an enemy to lure Naruto in. So, while Naruto is trying to save Tsunade, he has to also deal with the real mastermind behind the whole thing. This would add an extra layer of complexity to the story.
Naruto's understanding of sacrifice could deepen. If he has to put himself in great danger to save Tsunade, he'll learn more about what it means to sacrifice for others. He might recall the sacrifices of his predecessors like the Hokages and use that as motivation to keep going, even when the odds are against him.
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.
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.
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.
Perhaps Anko is trapped in a genjutsu and Naruto uses his own experience with breaking free from illusions to save her. He could sense her distress and use his chakra to disrupt the genjutsu, freeing Anko. This would show Naruto's growth and his ability to help those in need, even a more experienced ninja like Anko.
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.
