One idea could be that Hitomi has a special power that Naruto discovers during a mission. They then have to work together to keep this power a secret from the wrong people.

Maybe she has some information about a new threat and Naruto needs to protect her while getting that information.
A plot could involve Hitomi being a healer who helps Naruto when he is seriously injured in a battle. This could lead to a deep friendship or even a romantic relationship. They might also go on a journey together to find a rare herb that can save a sick friend. Along the way, they face various challenges and learn more about each other.
Perhaps Hitomi is a time - traveler who accidentally lands in Naruto's world. Naruto has to help her find a way back to her own time while also dealing with the chaos her arrival causes. They could form a bond as they try to understand the mysteries of time travel and how it affects their world.
A more complex plot might involve Tayuya being captured by an enemy group and Naruto being the only one who can rescue her.

As they escape from the enemy, they form a bond that is both unexpected and deep.
One plot idea could be Naruto trying to understand Pain's ideology on a deeper level while in the midst of battle.

Another could be Naruto getting trapped in one of Pain's jutsu and having to experience Pain's past traumas first - hand, which changes his perspective on him.
A more complex plot could be set in a time when there is a famine in the village. Ayame's ramen shop is struggling to get ingredients. Naruto, being the hero he is, offers to help. They travel to different lands to trade for ramen ingredients. Along the way, they encounter various characters from other villages, some friendly and some hostile. This journey not only strengthens their friendship but also helps to save the ramen shop and feed the village.

Along the way, a romantic relationship might start to develop between them.
Well, a cool plot could be that there is a mysterious force that links Naruto and Rin across different dimensions. Naruto discovers this connection and tries to find Rin in another dimension. As he does, they both realize that they have a shared destiny to save both their dimensions from a common threat. Maybe it's an ancient evil that was once sealed away but is now breaking free.
One plot idea could be that Selene, with her unique powers, somehow gets transported to the Naruto universe. She meets Naruto and initially they are at odds because of their different ways of handling things. But as they face a common enemy, they start to understand each other and work together. Their combined skills, Naruto's ninjutsu and Selene's otherworldly powers, make for an exciting adventure against the foe.

Maybe a story where Kurotsuchi discovers a new jutsu that she can't control and Naruto helps her. Naruto, with his experience in mastering difficult techniques, offers his guidance. As they work together to tame the jutsu, they learn more about each other's villages and cultures, and this new - found understanding strengthens their bond.
A plot could revolve around Naruto being magically transported into a different era where yukatas are the norm. He has to adapt to this new world while still being Naruto. He might use his ninja skills in unexpected ways in this yukata - wearing society, like using his shadow clone jutsu to help with traditional yukata - making tasks.
