Perhaps a plot where there is a competition in Konoha. Naruto, Hinata, and Tenten all enter. The competition involves various aspects like combat, stealth, and knowledge of ninja arts. Hinata's gentle yet strong nature, Naruto's determination, and Tenten's resourcefulness are all put to the test. They compete against each other but also support one another, leading to a great display of their characters and growth throughout the fanfiction.
A possible plot could be a story set in an alternate universe. Naruto is not the hero he is in the original story, but Hinata and Tenten believe in his potential. They work together to help Naruto find his true self and his powers. Along the way, they encounter old enemies who are now much more powerful, but through their combined efforts and friendship, they manage to grow stronger and face the challenges.
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 plot idea could be a training mission where Naruto, Hinata, and Tenten are paired together. They face a powerful enemy that forces Hinata to overcome her shyness and use her Byakugan more effectively. Tenten could show off her weapon skills, and Naruto, of course, his ninja way and new jutsu. Another idea is a love triangle situation where Hinata has feelings for Naruto, but Tenten also starts to develop a crush on him, creating some tense and emotional moments among the three.
One idea could be a story where they team up for a special mission. Maybe there's a powerful enemy threatening the village and they have to combine their unique skills. Sakura with her medical and combat skills, Ino with her mind - transfer jutsu, Hinata with her gentle fist and Byakugan, and Tenten with her weaponry expertise. They start off with some bickering due to their different personalities but gradually learn to work together and become a strong force.
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.
Another plot idea is that they explore their family history together. Since Naruto has always been an orphan and Tenten's family background isn't explored much in the original series, they could embark on a journey to find out more about their parents. Along the way, they would face many obstacles and meet various characters who either help or hinder their search, all while growing closer as siblings.
One idea could be a story where Naruto and Hinata are on a mission together, and Tenten joins them later. Maybe they encounter a powerful enemy that requires all of their skills combined. Tenten's weaponry skills, Hinata's Byakugan and Naruto's Nine - Tails chakra could be used in a creative way to defeat the foe.
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 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 idea could be a story where Neji and Tenten go on a special mission together. They face many challenges and in the process, Neji discovers a new side of Tenten's strength. Maybe she uses some unique weapons or techniques that Neji has never seen before, and he gains a new respect for her.
