There could be a plot where Naruto is mistaken for a powerful devil in the High School DxD world. Rias initially tries to recruit him or figure out his true nature. Along the way, they end up working together to solve a mystery that threatens both their worlds. This could involve Naruto using his shadow clones to gather information, and Rias using her devil powers to fight off any threats they encounter during their investigation.
One plot idea could be Naruto getting transported to the world of High School DxD where Rias is. He might use his ninja skills to help Rias in her battles against other devils or supernatural threats. Another could be Naruto teaching some of his ninja techniques to the characters in the High School DxD world, creating a new form of combat.
A more complex plot could be that there is a powerful enemy that threatens both Naruto's world and the world of Rias. Naruto and Rias's harem have to team up to defeat this enemy. Along the way, they face many challenges that test their abilities and relationships. Naruto's positive attitude and never - give - up spirit start to influence the members of the harem, and they in turn show Naruto new ways of using magic and power.
One idea could be that Naruto is somehow transported to the world of Rias Gremory. He, with his strong sense of justice and determination, catches Rias's eye. They start off as friends, training together. As they spend more time, they realize their feelings for each other. Naruto's unique powers also intrigue the other devils in Rias's peerage.
One plot idea could be that Naruto and Fuu team up to save a small village from a mysterious illness. Fuu's unique abilities and Naruto's determination combine to find a cure. Another could be that they get trapped in a strange dimension and have to work together to find a way out, facing various challenges along the way.
A plot could involve Kiba's dog Akamaru getting sick and Naruto using his unique skills and connections to help find a cure. This brings them closer together as they work towards saving Akamaru and also deepens their understanding of each other's values.
One plot idea could be the daughter's discovery of a hidden power within her that she has to learn to control, much like Naruto with the Nine - Tails. Another could be her forging her own unique ninja path that is different from her father's, while still respecting his legacy.
A more character - driven plot could be about the caretaker forming an unlikely friendship with a visitor to the ruins. The visitor could be from a completely different world or culture, and through their interactions, both characters grow and learn more about themselves and the significance of the ruins.
One interesting plot idea could be Shion having premonitions about Naruto's future challenges as Hokage and they work together to prevent them. Another could be that Shion is in danger and Naruto has to use his new - found powers to save her. It could also be a story where they go on a journey to discover a hidden power that only they can unlock together.
