Well, to write such a fanfiction, you have to really understand the characters of Jiraiya and Tsunade. Jiraiya is known for his pervy ways but also his loyalty and strength. Tsunade is tough as nails and has a lot of emotional baggage. You could start by exploring what led to their pregnancy. Was it a forbidden love? An accident? Once you've established that, you can start building the plot around their pregnancy. Think about how they'll deal with the news in the context of the ninja world. Will they be shunned? Will they have to hide it? And how will their relationship change? Will they grow closer or will the pressure of the situation drive them apart? There are so many possibilities to explore when writing this type of fanfiction.
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.
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.
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.
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.
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.
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 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.
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.
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.
Avoid the typical 'love at first sight' trope. Instead, focus on their long - standing friendship and how it gradually transforms. For example, show small moments of jealousy or protectiveness that they might have felt over the years but never fully acknowledged.
He would probably also feel angry. After all, he has sacrificed so much for the village and for them. He might start to question his own beliefs and values. But Naruto being Naruto, he would not give up easily. He would try to prove his innocence and show them that they are wrong. He could go on a journey to find evidence or seek help from other allies who still believe in him, like Shikamaru or Kakashi.
