Well, in the fanfic world, the author might have created a backstory or a set of rules. It could be that Tsunade's family lineage has been clearly defined in a way that excludes her from being considered an Uzumaki. Naruto, being a character within that fan - created world, has to abide by those rules. For example, perhaps her family tree has been traced and it shows no connection to the Uzumaki clan, so Naruto simply can't claim her as one.
In this fanfic, there could be multiple reasons. Firstly, the fanfic may be following a different interpretation of the Naruto universe's lore. It could be that the story has established certain criteria for being an Uzumaki, and Tsunade doesn't meet those criteria. Secondly, the plot might be driving towards a specific direction where Naruto's claim would disrupt the overall flow. For instance, if there are political or social aspects in the fanfic related to the Uzumaki clan, and Tsunade's association with them would cause chaos or go against the established order. So, Naruto can't claim Tsunade as an Uzumaki.
One implication could be on the power dynamics. If Tsunade was wrongly claimed as an Uzumaki, it might disrupt the existing balance of power related to the Uzumaki clan in the fanfic.
Naruto could be developed by having him face moral dilemmas that Tsunade has already experienced. Tsunade can guide him through these, and in the process, Naruto becomes more mature and worldly. Tsunade's character can be developed by Naruto challenging her traditional ways. For example, Naruto might suggest a new approach to handling village finances or medical training, which forces Tsunade to adapt and grow. This interaction would make both characters more three - dimensional in the fanfic.
Perhaps a shared experience like fighting a common enemy could bring them closer. If they are in a battle together and Naruto saves Tsunade's life, or vice versa, it could be the start of a deeper emotional connection. Tsunade might then open up about her family to Naruto, and Naruto could share his own feelings about family, as he has always longed for one.
It depends on the specific plot of the fanfic. Sometimes he could be on a secret mission, in a hidden village, or facing a new challenge in an unknown location.
In some fanfics, Naruto might hate Tsunade due to her decisions regarding the village. For example, if she makes choices that Naruto believes put the younger generation at risk or if she is too strict with the shinobi training policies. Naruto, being someone who values his friends and the future of the village, could grow to dislike her.
Maybe it's because you haven't met the specific requirements or conditions for the mission. Check the game instructions for details.
Maybe because Naruto has a large and diverse world - building. It's not just about the Uzumaki. There are other important clans like the Uchiha too.
It could be a friendship - based relationship. Naruto has a way of befriending everyone, and Tsunade is no exception. The lemonaid might be a common interest that brings them closer. For example, they could start having regular lemonaid - drinking sessions where they just chat about their daily lives, Naruto's progress in his ninja skills, and Tsunade's responsibilities as the Hokage.
One possible interesting storyline could be Tsunade teaching Naruto some unique medical ninjutsu skills. This would not only expand Naruto's abilities but also create a strong bond between them as mentor and student.
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.
