A plot could also involve Naruto being reincarnated at a different point in the Naruto timeline. For example, if he was reincarnated during the time of the Sage of Six Paths. He could have a major impact on the early development of ninjutsu and the ninja world.
A cool plot could be Naruto being reincarnated as an enemy of Konoha in a parallel universe. He has all his memories but has to fight against his former friends and home. This would lead to a lot of internal conflict for him. Also, he could be reincarnated into a time where there are new and strange forms of chakra that he has to learn to master in order to save the world again. For example, a chakra that is a combination of nature and spiritual energy.
One plot idea could be that Naruto is summoned to a different dimension where ninjutsu doesn't exist. He has to adapt and use his raw strength and wits to survive and find a way back. Another could be that he's summoned by an ancient clan that believes he's the key to unlocking a powerful, long - lost jutsu. They force him to help them, but Naruto tries to find a peaceful solution instead of just following their orders.
One plot idea could be that Naruto is framed for stealing a powerful and ancient scroll from the village. The real culprit could be a rogue ninja who has the ability to disguise as others. Naruto then has to prove his innocence while on the run from the village's forces. Another idea is that he's framed for a crime that was actually committed by a corrupt member of the village council, who wants to get rid of Naruto because he's seen as a threat to their power.
Some plot ideas in Naruto mates with a Kitsune fanfiction could involve the Kitsune bringing out a different side of Naruto. Maybe she teaches him about the Kitsune culture and values, which in turn changes his perspective on the ninja world. They could also have to protect their relationship from those who might see it as a threat, such as some of the more traditional ninja clans in Konoha. And there could be a story where they have to combine their powers to save the world from a new, powerful dark force that neither could defeat alone.
One plot idea could be exploring Itachi's time in the Anbu in more detail. For example, showing his first difficult missions and how they shaped his views on the village and his family. Maybe he has to make a choice between following a cruel order from the higher - ups in the Anbu or protecting an innocent. Another idea is a story where Naruto somehow gets a glimpse into Itachi's Anbu past through a special jutsu or a shared dream. This could lead to Naruto having a new understanding of Itachi and changing his perspective on him.
One idea could be that the reincarnated character has memories of the future of the Boruto world. So they try to prevent certain disasters from happening, like the fall of Konoha. Another could be that they use their modern - day knowledge to revolutionize the ninja technology in the Boruto universe.
One idea could be that the reincarnated character has knowledge of future events in the Danmachi world. For example, they know about certain monsters' weaknesses or hidden treasures. This could give them an edge as they navigate the dungeon. Another could be that they are reincarnated as a non - human race in the Danmachi world, like a spirit or a dwarf, and they have to deal with the different cultural and physical aspects of that race. A third idea is that the character reincarnates with a special ability that doesn't exist in the normal Danmachi world, like the power to control time on a small scale, which would completely change their adventures in the dungeon.
One idea could be that the protagonist, reincarnated as a dinosaur, tries to prevent the extinction event. They could use their human knowledge to find a way to survive the impending asteroid or environmental changes.
A third plot idea could be the relationship between the sword and the other characters. Since it's reincarnated as a sword, it can't communicate in the traditional sense. So, how it forms bonds with the people around it, like the protagonist who might be the one it eventually chooses as its wielder. It could be through dreams or visions that it imparts knowledge or feelings to the characters, creating a unique and complex relationship dynamic.
One idea could be reincarnating as a vampire hunter who then falls in love with a vampire. Another could be being reincarnated as a long - lost relative of one of the main characters and causing chaos in the vampire - human relationships. Or perhaps being reincarnated as a wolf shifter with a special ability that changes the power dynamics in the Twilight world.
