The most immediate consequence would be a huge power boost for Naruto. He'd likely gain abilities like teleportation, space - time manipulation, and extreme chakra control. This could make him a target for those who want that power. Also, it might affect his mental state as he tries to cope with the sudden influx of power and the knowledge that comes with Kaguya's abilities.
Well, if Naruto absorbs Kaguya in a crossover fanfiction, it could drastically change the power balance. Naruto already has a lot of power, and adding Kaguya's abilities would make him nearly invincible. It might also change his relationships. His friends could be in awe or a bit scared of his newfound power. And it would surely change the way he faces future enemies. Instead of just fighting, he could potentially just overpower them with his new combined abilities.
Well, Naruto could change Kaguya in the fanfiction by introducing her to the concept of redemption. Given his own journey of facing his inner demons and coming out stronger, he might convince Kaguya that she can atone for her past sins. He may take her on a journey through the ninja world, showing her how people have rebuilt and thrived despite the chaos she once caused. This could make her re - evaluate her actions and change her perspective on the world and her place in it.
In the fanfiction, Naruto could enter Kaguya's mind. He might discover her past traumas that led her to become so power - hungry and vengeful. By understanding her pain, Naruto could offer her forgiveness and a new path. He could show her a vision of a future where she is part of a united world, not feared or hated, but respected and loved if she changes her ways. This could be a powerful incentive for Kaguya to change.
One idea could be that Naruto somehow gets trapped in a dimension where Kaguya has become a yandere for him. She tries to keep him there all to herself, while Naruto has to figure out a way to escape and also deal with her obsessive behavior.
One possible scenario could be that Kaguya, with her vast power, teaches Naruto unique jutsu. Since she has knowledge of chakra from the very beginning, she might show Naruto how to access and control chakra in ways that no one else in the village could. This could make Naruto even more powerful and give him an edge in battles. For example, she could teach him how to better utilize the Nine - Tails' chakra in harmony with his own.
There are indeed some out there. A lot of fanfiction writers like to take the concept of Naruto and Kaguya and give it a romantic spin. However, the quality can vary greatly. Some might focus more on the emotional connection between them, while others might include more action - adventure elements along with the romance. It really depends on what you're looking for in a fanfiction.
In 'Naruto and Kaguya love' fanfiction, one of the common themes is the discovery of self - worth. For Kaguya, through Naruto's love, she can start to see herself in a new light and realize her own value. Another theme is the breaking of cycles. Kaguya was part of a cycle of power and conflict, and Naruto's love can be the key to breaking that cycle. And of course, the theme of love against all odds is also very common, as their relationship is not an obvious or easy one given their respective roles in the Naruto story.
It's also possible that some non - human characters could be part of the harem. For example, some of the tailed beasts in human form (if that's possible in the context of the fanfiction). They would bring their own set of powers and a very different kind of relationship with Naruto compared to the human characters in the harem.
The baby could have the power of Naruto's Nine - Tails chakra, which gives great strength and speed. Combined with Kaguya's chakra, which is extremely powerful and has space - time manipulation abilities, the baby might be able to warp reality. It could also have Naruto's ability to create multiple shadow clones, but with an added twist from Kaguya's powers, like the clones having space - time abilities too.
