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.
A fanfiction could revolve around a mysterious illness that affects the ninja world. Naruto, Temari and Tenten are among the few who seem immune. They are tasked with finding the source of the illness and a cure. During their journey, they discover that it was caused by an ancient curse. With Naruto's strength, Temari's strategic mind and Tenten's precision, they manage to break the curse and save the ninja world.
Maybe a story where Temari comes to Konoha to train with Tenten. Naruto gets involved as he's always eager for new training partners. They start off not getting along too well. Tenten is a bit jealous of Temari's natural power, and Temari thinks Tenten is too uptight. But Naruto, with his goofy charm, helps them see the best in each other. They end up learning new techniques from one another and become good friends.
There could be a fanfiction where they are all transported to a modern - day world by some kind of magic or jutsu gone wrong. They then have to adapt to this new world while also trying to find a way back to their own world. Along the way, they could learn about modern technology and culture, and how different it is from their ninja world. This could lead to some comical situations as well as some deeper moments of self - discovery for each of them.
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 that Naruto and Tenten are banished due to a false accusation of plotting against the village. They then have to prove their innocence while on the run. They might encounter old enemies who have also been exiled and form an unlikely alliance to clear their names.
One idea could be that Tenten becomes yandere for Naruto after he saves her life in a battle. She then starts to secretly eliminate any girl she sees as a threat to her 'relationship' with Naruto. For example, she might try to sabotage Hinata's attempts to talk to Naruto.
One idea could be a story where Naruto, Hinata, and Tenten go on a mission together. They face a powerful enemy and have to rely on each other's skills. Naruto uses his Rasengan, Hinata her Gentle Fist, and Tenten her weaponry skills. Another plot could be a time - travel story where they go back in time and have to change an important event in the ninja world. It could be something related to the founding of their villages.
One common theme is friendship. Since they are from different villages, it's interesting to see how they overcome their differences and form a bond, like in the fanfic 'The Allied Trio' where they fight against a common enemy and in the process, become great friends.
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.
