One idea could be that Naruto and Temari team up for a special mission after they've retired from being ninjas. They have to face an old enemy who has new powers. Another could be that they start a ninja school together in a different village, teaching new generations their skills.
Perhaps in the fanfiction, Naruto and Temari discover a hidden scroll that reveals a long - lost jutsu. They then have to figure out how to use it without causing chaos in the ninja world. Or they could be on a journey to find a cure for a strange illness that is affecting ninjas who have retired, all while dealing with their own relationship growing.
A really interesting plot could be a time - travel fanfiction. Naruto and Temari are sent back in time to a crucial moment in the history of their villages. They have to work together to make sure the events unfold in a way that doesn't change the future too drastically, but also helps to prevent some of the darker events that occurred in their past.
One idea could be that Shikamaru and Temari have to go on a joint mission in a foreign land. They face various challenges together which make them rely on each other's skills. Shikamaru uses his intelligence to outwit the enemies while Temari uses her wind jutsu. This mission brings them closer and they start to develop deeper feelings for each other.
One interesting plot idea could be a mission where Naruto and Temari are paired together. They start off bickering as they have different ways of approaching things, Naruto being more impulsive and Temari more calculating. But as the mission progresses, they learn to understand and complement each other's skills. For example, Naruto's ability to quickly adapt in battle combined with Temari's strategic thinking could lead them to defeat a powerful enemy. Another idea is a story set in a time where the ninja villages are having a cultural exchange. Naruto and Temari get to know each other's cultures better, which deepens their bond. It could also involve some friendly competitions between them related to their respective village's specialties.
One idea could be a mission where Naruto, Temari and Tenten are teamed up. They have to retrieve a powerful and ancient scroll from a hidden temple. Along the way, Naruto's determination and positive attitude inspire Temari and Tenten. Tenten shows off her weapon skills, and Temari uses her wind jutsu to clear obstacles. They face various traps and enemies, and in the end, they bond over their shared success and newfound respect for each other.
One plot idea could be that Temari is arranged to marry someone from a minor clan in Konoha. This causes a stir as she is from Suna and has a high status. She initially struggles with the idea of being married into a less - prominent family, but then discovers that the family has some unique and secret techniques that could benefit Suna. Another idea is that the arranged marriage is part of a prophecy. Temari and her future partner must work together to fulfill the prophecy, which involves saving both Konoha and Suna from a great danger.
Perhaps Naruto, in his banished state, has some new and unique abilities that Temari is intrigued by. She decides to help him master these powers in secret. As they train together, feelings start to develop. Their relationship could then be a source of conflict between Konoha and Suna as the two villages have different views on Naruto's banishment and his newfound connection with Temari.
One idea could be a rogue ninja who was once a close friend of Naruto but turned due to a misunderstanding. They could have unique powers and be on a mission to prove their own version of justice.
A cool plot could be that an ice ninja has the power to freeze time within ice. The Akatsuki wants to capture this ninja to use their power for their own evil plans. Naruto and his team must protect the ice ninja and figure out a way to stop the Akatsuki from getting their hands on this dangerous ability.
One idea could be a story where the Ninja Wire is used in a new and unexpected way during a major battle. For example, the characters could use it to create complex traps that not only ensnare enemies but also redirect attacks. Another plot could revolve around a young ninja who discovers a unique property of the Ninja Wire and has to keep it a secret while trying to master it.
One idea could be a story where a medical ninja discovers a new healing jutsu during a difficult mission and has to protect the knowledge from enemy ninjas. Another could be about a medical ninja who uses their skills to heal a long - forgotten and powerful ninja, who then becomes an ally. Or perhaps a story of a medical ninja training under Tsunade to become the best in the village.
