One idea could be a story where Naruto discovers a hidden samurai clan and has to learn their ways to defeat a new powerful enemy. Maybe he has to master their unique sword techniques.
There could be a plot where the ninjas in the Naruto world are being influenced by Aku's dark magic. Samurai Jack, with his unwavering sense of justice, teams up with Naruto and his friends to break the spell. They then travel to Aku's lair to take on Aku directly. Another interesting idea is a world where the Naruto characters are re - imagined as samurai, and Jack has to train them in the ways of the samurai to face a new threat that combines the worst of both their worlds.
One idea could be that the Samurai Girl is on a mission in the Ninja world and crosses paths with Naruto. They initially have misunderstandings due to their different cultures but gradually learn to work together. For example, she might be tasked with retrieving a stolen samurai artifact that has ended up in the hands of a rogue ninja. Naruto, being the helpful and curious person he is, decides to join her in the quest.
Another plot could revolve around the relationships between the existing legendary summons. Maybe there's a power struggle among them, and Naruto has to step in and mediate. He could learn about their ancient rivalries and use his skills to bring them together to face a common foe like a powerful, ancient evil that has been awakened.
One idea could be a story where Naruto discovers a hidden ancient jutsu that changes the power balance in the ninja world. He has to learn to master it without being corrupted by its power.
One interesting idea could be the unique fighting style of the blind samurai. Since they can't rely on sight, they might have developed an extraordinary sense of hearing or other senses to detect opponents' movements, like how real - world blind martial artists do. Another idea could be the backstory of how the character became a blind samurai in the Naruto universe. Maybe it was due to a tragic battle or a special mission gone wrong.
One idea could be the young samurai going on a journey to find a lost ancient sword. Along the way, he meets various characters who either help or hinder him.
One idea could be an OC who is a long - lost relative of Afro. Maybe a cousin who was separated during a raid on their village. This OC could have a different fighting style but the same goal of avenging their family. Another plot could be an OC who is a rival samurai, trained in a secret dojo. They cross paths with Afro and challenge him at every turn. The OC could be after the Number 1 headband for a different reason than Afro, like to prove the superiority of their dojo.
A more character - centered plot could be about the relationships between the Rangers. Like a story where Emily struggles with her feelings for Kevin, and how this affects their teamwork as Power Rangers. This could add an interesting layer of drama to the fanfiction.
Well, a great plot for Blue Eye Samurai fanfiction could involve her facing a new and powerful enemy that has a personal vendetta against her. This enemy could be a former ally turned bad.

One idea could be a samurai who is transported to a modern world and has to adapt to new technologies while still holding onto his samurai values. Another could be a story about a female samurai in a male - dominated world, facing discrimination but proving herself as a great warrior. Or perhaps a samurai who forms an unlikely alliance with a group of bandits to fight a common enemy.
