Well, they could start as rivals. Naruto thinks Najenda's way of fighting and leading is too harsh, and Najenda sees Naruto as too naive. But then they are forced to work together on a mission. During the mission, they face various challenges that make them realize the strengths in each other's methods. They gradually become friends and allies, and by the end of the story, they have a newfound respect for each other. This plot would be full of character development and interaction without any need for adult content.
A possible plot could be that a new threat emerges that requires both Naruto's and Najenda's unique abilities to defeat. Maybe it's a powerful demon or an evil organization that has the power to control minds. They have to put aside their differences (cultural and otherwise) and form a plan. Along the way, they also learn about each other's values and beliefs. For example, Naruto could teach Najenda about the importance of friendship in his ninja world, and Najenda could show Naruto the importance of strategic planning in her world of resistance. This way, the story focuses on their cooperation and mutual growth rather than any adult - related themes.
One idea could be that Fem Tora is a foreign exchange ninja from another village. Naruto is assigned to show her around Konoha. They explore the different training grounds, visit the ramen stand, and along the way, they learn about each other's cultures and form a strong friendship. Another plot could be that Fem Tora discovers a new chakra - based ability and Naruto helps her master it. They train together and face some initial setbacks but eventually succeed.
Well, a common plot point is the culture shock. Naruto comes from a world full of ninjas and chakra, while Najenda is from a more modern - ish world with different forms of combat. Their reactions to each other's worlds can be really interesting. For example, Naruto might be amazed at the technology Najenda has access to, and Najenda could be intrigued by the idea of chakra.
Another idea is that Zelda characters find themselves in the Naruto world. They could get involved in the ninja academy and learn about chakra. Maybe Zelda herself could try to master some of the ninja arts and use her magic in combination with it. This would lead to a lot of interesting interactions between the Zelda characters and the ninja students.
One plot idea could be a training arc. Naruto could teach Illya some basic ninja skills like stealth or tree - climbing, while Illya could show Naruto some of her magic spells for defense. Another idea is a mystery - solving plot where they team up to figure out why strange things are happening in both their worlds. For example, strange creatures are appearing in Konoha and in Illya's town that seem to be related.
One plot idea could be that Kushina and Danzo have to work together to protect the village from a powerful outside threat. They start off distrusting each other, but as they face challenges, they gradually learn to respect and rely on one another.
Here's another idea. In the My Little Pony world, there is a prophecy about heroes from another dimension coming to help in a time of great need. The Naruto characters arrive just in time. A group of ponies, each with their own special skills and personalities, gather around the Naruto characters. They form a bond similar to a harem, not in a romantic way but in a sense of loyalty and friendship. They embark on a journey to find a powerful magical artifact that can save both the Naruto world (which is somehow also in danger due to the connection) and the My Little Pony world from an ancient evil. Along the way, they face various challenges, learn from each other, and grow as characters.
One plot idea could be a female Sasuke who uses her unique skills in a different way than the male Sasuke in the original. For example, she might focus more on diplomatic solutions to problems in the ninja world, using her intelligence and combat skills to broker peace treaties.
A fanfiction could be about Naruto starting a ninja academy in a small, war - torn village. He uses his own experiences and teachings from his masters like Jiraiya to train a new generation of ninjas. It could explore how he imparts values like friendship, hard work, and perseverance to the young students.
One plot idea could be that Naruto and Wonder Woman meet when a strange rift in the multiverse opens up. They have to work together to close the rift while also dealing with the fact that their powers work very differently. Naruto could show Wonder Woman his ninjutsu, and she could introduce him to the concept of the Gods in her world.
One plot idea could be that Naruto gets transported to the world of Equestria. Princess Celestia senses his strange power and they start to communicate. Naruto helps the ponies in Equestria deal with a new threat using his ninja skills, and in return, the ponies teach him about their magic. It could be a story of friendship and cultural exchange.
