A possible plotline is that Tsunade discovers she is pregnant. This creates a whole new set of challenges and joys for both of them. Naruto has to balance his duties as a shinobi and a soon - to - be - father. Tsunade, on the other hand, has to deal with her own insecurities about being an older mother. Also, they might have to face threats from enemies who see the baby as a potential target because of their important positions in the village.
In a fanfiction, the plot could start with Naruto and Tsunade realizing their feelings for each other during a difficult time for the village, like a major war or a natural disaster. After they get married, they could go on diplomatic missions together. Tsunade's experience and Naruto's charisma could help in forging new alliances. However, they also have to deal with internal power struggles within the village, where some clans might be jealous of Naruto's new - found influence through his marriage to Tsunade.
One plotline could be about Naruto helping Tsunade to further reform the Hidden Leaf Village. Since Naruto is now married to Tsunade, he has more influence and they work together to improve the village's economy, ninja training systems etc. Another could be that they face opposition from some traditionalist shinobi who don't approve of their age - gap relationship.
One common theme is the idea of Naruto breaking through Tsunade's tough exterior. Tsunade is often portrayed as a strong - willed and sometimes cold character, and Naruto's warm - hearted nature helps him get closer to her.
Another plotline might be that Tsunade is affected by some kind of dark magic or genjutsu that makes her turn against Naruto. Naruto, realizing it's not really Tsunade's fault, still has to fight her to try and break the spell. He could call upon his friends for help, but in the end, it's his determination and his bond with Tsunade that helps him reach her and break the control.
One possible plotline could be that Naruto leaves with Tsunade on a mission to find a rare herb that is said to have the power to heal any wound. Along the way, they face various enemies who also want the herb for their own malicious purposes. Naruto's skills and Tsunade's wisdom would be put to the test as they battle their way through.
Well, I've come across a few. Some focus on how Naruto and Tsunade's relationship develops over time. In these fanfictions, they might start with a mutual respect and then gradually fall in love. It could be due to Naruto's growth and Tsunade seeing him as a reliable partner, not just a young ninja. There are also those that add in some action and adventure elements around their relationship.
One plot idea could be that Naruto, after achieving great peace in the ninja world, decides to settle down. Tsunade, who has seen Naruto grow from a young boy to a great hero, realizes her feelings for him. Shizune, having been by Tsunade's side all along, also develops feelings. They all decide to form an unconventional family. Naruto's ability to bring people together and his unwavering spirit could be central to this plot.
One possible plotline could be that Naruto discovers a new form of chakra control that gives him an edge over Tsunade. He uses this to take charge in a dangerous mission where Tsunade was initially leading.
Another plotline could be Tsunade's role in rebuilding the village after a major battle. It could show her leadership skills, her decision - making process, and how she works with other characters to bring the village back to its former glory. This would involve aspects like rebuilding infrastructure, training new ninjas, and restoring the village's economy.
Maybe there's a plotline where Naruto is arranged to marry someone from the Rookie 9 for political reasons in the village. At first, they might be reluctant, but as they get to know each other better, they truly fall in love and build a strong marriage. This could involve them working together to improve the village's relations with other villages through their union.
A possible plotline could be that Naruto is chosen by Kami for some greater purpose related to the balance of the world. As a result, they get married. Their union then brings about a new era of peace and prosperity as Naruto uses Kami's power to end all wars. Another plotline might be that Kami falls in love with Naruto's pure heart and determination. She decides to marry him, but they first have to convince the shinobi world that their union is for the good of all.
One possible plotline could be Naruto feeling extremely lost and having to find his own way to become stronger without their guidance. He might start to question his own worth and abilities, but then he could meet new allies who help him realize his true potential on his own. For example, he could encounter some other outcast ninja who have their own unique skills and together they form a new kind of ninja team that challenges the traditional ways of the ninja world.
