A possible plot could involve Naruto being banished and finding refuge in a hidden place. Kurenai, while on a mission in that area, discovers him. At first, there is tension as she is a Konoha ninja and he is banished. But as they start to communicate, they learn about each other's dreams and fears. They end up working together to protect the place from a group of rogue ninjas, and during this time, their relationship blossoms into something more than just friendship.
One plot idea could be that Naruto, after being banished, crosses paths with Kurenai who is on a solo mission. She initially has her doubts about him due to his banishment but gradually realizes he was wrongly accused. They team up to face a common enemy that threatens the village from afar. This could lead to a growing bond between them.
One plot idea could be that Vampire Naruto has to protect Kurenai from other vampires who see her as a threat. Since Naruto has unique powers as a vampire, he can use his speed and strength to fend them off.
Another idea is a story where Naruto joins the ANBU and is paired with Kurenai for a special undercover operation. They have to infiltrate an enemy organization that is suspected of planning an attack on Konoha. Along the way, they learn more about each other's pasts and develop a strong bond as comrades.
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.
A plot might involve Kurenai and Naruto teaming up to solve a mystery within the Leaf Village. There could be strange disappearances that seem related to a long - forgotten jutsu. They would have to use their unique skills, Naruto's brute strength and Kurenai's genjutsu, to uncover the truth. Also, a story where Kurenai discovers a new side of Naruto during a joint mission, like his ability to inspire others in a difficult situation, could be interesting.
One idea could be that Naruto accidentally discovers a hidden jutsu that makes him irresistible to women, including Kurenai. This leads to a series of comical and heart - warming situations as he tries to deal with this new - found effect on the female ninja in the village, especially Kurenai who has her own reservations at first.
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 the character with the Sharingan is banished due to false accusations of using its power for evil. He then has to journey alone, facing challenges and learning to control his power in new ways. Maybe he meets a group of outcasts who he befriends and together they fight against the unjust system that banished him.
One plot idea could be Naruto being banished to the world of One Piece. He could join the Straw Hat Pirates and use his ninja skills in new and exciting ways. For example, his shadow clone jutsu could be used for various tasks on the ship. Another idea is that he gets banished to the Bleach universe. He might learn about Soul Reapers and Hollows, and his chakra could be seen as a unique form of spiritual energy there. Maybe he could even train with the Soul Society to become stronger.
A possible plot could involve the banished mercenary being from a long - lost clan. The reason for his banishment was a false accusation by a rival clan. As he wanders the Naruto world as a mercenary, he discovers clues about his clan's true heritage and power. He then uses his skills as a mercenary to gather allies and resources to prove his clan's innocence and restore its honor. Along the way, he crosses paths with Naruto and his friends and they either help or hinder his quest depending on the situation.
One idea could be that the banished Naruto discovers the female Kyuubi's true nature. He realizes she's not just a force of destruction but has her own emotions and desires. As they interact, Naruto starts to see her as an ally. For example, she could help him gain new powers in secret while he's exiled, and together they plan to prove his innocence to the village.
