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.
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.
Maybe there's a situation where Jiraiya writes a novel that Tsunade reads. In the novel, he describes a love story with a kiss that is clearly inspired by his feelings for her. Tsunade, touched by this, confronts him and then they share a kiss. This could lead to a series of events where they have to deal with their new - found feelings in the context of the ninja world, with all its politics and rivalries.
Their marriage could lead to a more unified ninja world. Since Tsunade is from Konoha and Jiraiya is a well - known and respected figure, other villages might see their union as a sign of Konoha's stability and strength. This could encourage more peaceful relations among the villages.
One possible plot could be that after years of adventures and unspoken feelings, Jiraiya finally decides to settle down. He proposes to Tsunade in a very Jiraiya - style, perhaps writing a novel about their story and presenting it to her. Tsunade, who has always had deep feelings for Jiraiya despite their bickering, accepts. Their married life could be filled with Jiraiya still going on occasional missions while Tsunade manages the village, and they have to navigate the challenges of being in a relationship while having important responsibilities.
One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
In the fanfiction, perhaps they face some challenges after getting married. Maybe there are issues with integrating their different magical abilities and how they use them in a combined way. But through love and understanding, they overcome these obstacles and their relationship becomes even stronger.
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.
One possible fanfiction could be set in their early days. Jiraiya, with his brash and confident self, tries to court Tsunade in his own clumsy way. Tsunade, initially resistant, starts to see his true heart beneath the bravado. They could go on adventures together, and during a dangerous moment, Jiraiya's protection of Tsunade makes her realize her deeper feelings for him.
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.
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.
