One idea could be that they accidentally find out they're expecting during a mission together. Maybe they had a one - time moment of closeness before and now have to deal with the unexpected pregnancy. This could lead to a lot of drama as they both have important roles in their village and their relationship has always been complex.
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.
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.
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.
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.
One possible reason could be a misunderstanding. Maybe Tsunade misinterprets Jiraiya's actions or words. For example, if Jiraiya writes something in his book that Tsunade takes the wrong way, she might lash out at him. Another reason could be related to their past. If there are unresolved issues from their earlier days together, like an old argument or a failed mission where they had differences in opinion, it could lead to Tsunade hurting Jiraiya in the fanfiction. It could also be a situation where Tsunade is trying to protect Jiraiya in a strange way. She might think that by pushing him away or causing him physical or emotional pain, she is actually saving him from a greater danger that she foresees.
Another good place could be some Naruto - focused forums. There are often threads dedicated to sharing and discussing fanfictions. Members of these forums might recommend some great Tsunade and Jiraiya fanfictions that they have read. It's also a great way to interact with other fans who have similar interests.
Adventure - themed fanfictions are also common. Since they are both powerful ninjas, authors like to create stories where Tsunade and Jiraiya go on dangerous missions together. These stories might include battles against powerful enemies and the development of their relationship during the course of the adventure. It could be about how they learn to trust and rely on each other more during these tough situations.
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.
