Well, Tsunade being his grandma could give Naruto more direct access to her powerful medical ninjutsu knowledge. He might learn quicker and use it to his advantage in battles, like healing himself faster. This could also boost his confidence, knowing he has such a strong family connection.
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.
She might be initially shocked. Given her own past traumas and her relationship with Naruto, she could be hesitant at first. But then, considering Naruto's lonely situation, she might warm up to the idea and show a more maternal side towards him.
At first, their relationship would be very awkward. Naruto would be a bit shy and Tsunade might be stern. But as they get to know each other better, they could become friends. Eventually, they might develop romantic feelings. For example, Naruto could start to admire Tsunade's leadership skills and Tsunade could be impressed by Naruto's growth.
In many fanfictions, Naruto's determination and positive attitude start to rub off on Tsunade. She has been through a lot and is a bit jaded, but Naruto's energy makes her feel alive again. This new - found connection leads to a budding romantic relationship. For example, Naruto might bring her small gifts from his travels, which are simple but meaningful gestures that slowly warm Tsunade's heart.
If Naruto hypnotizes Tsunade, it could initially disrupt her leadership. She might make uncharacteristic decisions that could throw the village into chaos. For example, she could start allocating resources in a strange way.
Tsunade's character might develop by becoming more maternal towards Naruto. Saving him could make her see him as more than just a village ninja. She could start to care for him in a more personal way, like a mother figure.
The story dynamics would shift significantly. Naruto would be part of the Senju clan in a more direct way. This could mean he has a different standing in the village. Tsunade might pass on her unique skills and knowledge more readily. He could also have a different role in the political aspect of the village. Maybe he would be more involved in clan meetings and decisions. This new family connection could also influence how he is perceived by the other villages. They might be more cautious or more eager to form alliances with Konoha because of Naruto's relation to Tsunade.
The relationship would become extremely complex. Naruto, who respects Tsunade deeply, would be uncomfortable with the power dynamic. He would constantly try to find a balance between respecting her as a person and fulfilling whatever the 'slave' situation entails. Tsunade, on the other hand, would be in a position of having to follow Naruto's commands, which would be a huge shift from her normal authoritative role.
His approach to problems would be different. Naruto usually rushes into things head - on. But as Tsunade's grandson, he could be more strategic. Tsunade is a smart leader and a skilled ninja. Naruto could learn from her how to analyze situations better. Also, his relationship with Sasuke would be affected. He might be more of a guiding figure to Sasuke, rather than just a rival, as he would have a stronger sense of responsibility from his family connection.
Well, it could make Naruto more confident. Having Tsunade as a mother - figure gives him a sense of stability. He might grow to be more empathetic as he experiences a different kind of family bond. Tsunade's tough - love approach could also toughen Naruto up further and teach him more about leadership and responsibility.
