In fanfiction, Tsunade might also hurt Jiraiya by using her political power against him. For example, she could ban him from the village or restrict his movements if she believes he is a threat to the village's security in some way. This would not only limit his freedom but also damage his reputation among the villagers. Or she could use her medical knowledge in a negative way, like withholding treatment if Jiraiya is injured, although this would be a very extreme and out - of - character action for her.
One way could be through public humiliation. Tsunade is a respected figure in the village. If she publicly criticizes Jiraiya for his actions or his way of life, it could be very hurtful. For instance, if she mocks his pervy ways in front of the whole village, it would be a huge blow to Jiraiya's pride. Also, she could use her influence over their mutual friends to isolate Jiraiya, which would cause him emotional pain.
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.
In Tsunade and Jiraiya love fanfiction, it often shows Tsunade's vulnerability. Usually seen as a strong and tough leader, when it comes to her feelings for Jiraiya, she can be shy and hesitant. For example, she might blush when Jiraiya compliments her, which is a side of her not often shown in the original series. This shows a different dimension of her character.
In this fanfiction, their relationship would be transformed. They would be like a married couple in a way, but without the formalities. Jiraiya would probably tone down his womanizing ways as he has a family to think about now. Tsunade would be more open and less prickly around Jiraiya. They would bicker less and cooperate more. Their relationship would be centered around Naruto, and as he grows, they would grow together as a family unit, with their bond getting stronger over time.
First, you need to establish their relationship. Were they secretly in love all along? Or was it a spur - of - the - moment thing that led to the pregnancy? Then, think about the reactions of the other characters. How would Naruto react? Or Kakashi? Next, consider the challenges they'll face. For example, Tsunade is a strong - willed woman and Jiraiya is a bit of a free spirit. How will they adjust to the idea of becoming parents? Also, you can add some elements of the Naruto world, like how their pregnancy might be affected by chakra or ninja techniques.
A fanfiction could depict their married life as a blend of adventure and domesticity. They could go on missions together, using their combined skills to defeat enemies. At home, they would enjoy simple pleasures like cooking together (even if Jiraiya is not a very good cook) and sharing stories of their day. Their relationship would be a balance of their individual personalities and the love they have for each other.
Naruto may also develop a darker side to his personality. The abandonment could make him feel betrayed and angry. He might struggle with controlling his emotions, especially his anger. However, this could also lead to him learning how to channel that anger into power in a more controlled manner, like he did with the Nine - Tails' chakra, but in a more refined way.
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.
In such a fanfiction scenario, it could be due to a misunderstanding. Maybe there was false information spread about Naruto that made Jiraiya and Tsunade believe he had done something unforgivable. For example, an enemy could have framed him for a major crime against the village.
A fanfiction about their marriage could explore their past traumas and how they heal together. Jiraiya has his own demons from his past missions and relationships, and Tsunade has lost loved ones. Through their marriage, they could find solace in each other. For example, Jiraiya could comfort Tsunade during her nightmares about losing her brother and lover, and Tsunade could give Jiraiya the stability he always craved. Their relationship would be a journey of growth and mutual understanding.
In the original story, Naruto respects and looks up to Jiraiya as his mentor. He also has a good relationship with Tsunade. But in this fanfiction, the hatred is a complete departure. It changes the whole dynamic of their interactions.
Another aspect is Jiraiya's sense of humor. He can make Tsunade laugh even in the darkest of times. His jokes and light - hearted nature can break through Tsunade's tough exterior and make her feel more at ease around him, which is a first step towards falling in love in the context of these fanfictions.
