A really interesting plot would be if Kaguya's powers and Naruto's godlike powers combined accidentally, creating a rift in the space - time continuum. They then have to work together to fix it while also dealing with the various threats that emerge from the rift. This would involve a lot of action and also exploration of their relationship as they are forced to rely on each other. It could also show how they learn from each other's powers and experiences. For example, Kaguya could teach Naruto about some ancient and forgotten ninja techniques, while Naruto could show Kaguya the value of friendship and teamwork in the modern ninja world.
One plot idea could be that Naruto, in his godlike state, has to train Kaguya to adapt to the new ninja world. Since she has been out of touch for so long, Naruto teaches her about new jutsus and ninja ethics.
Maybe Naruto's godlike powers allow him to enter Kaguya's memories. He then discovers secrets about the origin of chakra that were long forgotten. Together, they embark on a journey to uncover more about these secrets and how they can use this knowledge to better the ninja world. This plot would involve a lot of mystery and discovery, and also give a chance for their relationship to develop as they share this unique experience.
One plot idea could be that Naruto, using his unique ability to understand and reach out to others, tries to find a way to redeem Kaguya. He might journey through different dimensions to learn more about her past and what led her to become so power - hungry. This could involve him facing challenges in these strange dimensions and having to rely on his ninja skills as well as his compassion.
Maybe a fanfiction where Kaguya is reborn in a different form and Naruto is the only one who can sense her true identity. They form an unlikely alliance to fight a new common enemy that threatens both the ninja world and the secrets Kaguya holds.
One idea could be a story where Naruto has to team up with Kaguya to stop a new, even greater threat that is emerging in the ninja world. Maybe a powerful enemy from another dimension that is after Kaguya's power and Naruto's unique abilities. This would force them to put aside their differences and learn to work together, leading to some really cool fight scenes and character development.
One idea could be that Naruto, after achieving great power, somehow travels back in time and meets Kaguya before she turned evil. He then forms a harem with her and some other female characters from the Naruto universe who are also drawn to his unique power and kind heart.
An interesting plot could be that the soulbound connection between Kaguya and Naruto is initially a mystery. Naruto starts having strange dreams and visions related to Kaguya, and as he tries to figure out what's going on, he discovers that their fates are intertwined on a much deeper level. This discovery could set off a chain of events where they have to work together to prevent an ancient evil from being unleashed. The connection could also make Naruto a target for those who fear Kaguya's return, forcing him to protect both himself and the new bond he has with her.
Well, a possible plot could be set in an alternate universe where Kaguya is resurrected as a yandere. She sees Naruto as the key to her new world order and her yandere love makes her go to extreme lengths to get him on her side. Maybe she uses her powers to create illusions that only Naruto can see, trying to manipulate his perception of reality and draw him closer to her.
Maybe in the fanfiction, Kaguya's power is split among several individuals in the Naruto world and Naruto has to find a way to reunite it without causing chaos. Along the way, he discovers hidden secrets about Kaguya's origin and her true intentions.
Another plot could be that both Naruto and Kaguya are sent back in time together accidentally. They end up in a time when the ninja world was just beginning. They have to work together to survive in this primitive world, and in the process, they start to understand each other better. Naruto tries to teach Kaguya about the concept of friendship and loyalty, which she has long forgotten. As they face various challenges, their relationship evolves, and they may even find a way to change the future for the better.
One interesting plot idea could be that the female Kaguya clan member has a unique power that Naruto needs to defeat a new, powerful enemy. So, they team up and during their journey, they start to develop feelings for each other. Another idea is that she is sent to Konoha as an emissary from the Kaguya clan. Naruto is assigned to show her around, and they gradually fall in love while sharing their different cultures. Maybe she also has a connection to the Otsutsuki clan that could add more mystery to the story.
One idea could be that Kaguya is reborn in a different form and Naruto has to help her remember her past without her turning evil again. It could involve them traveling through different dimensions in the Naruto world to piece together her memories.
