Naruto's relationship with Kakashi would be interesting. Kakashi, being a knowledgeable ninja, would likely try to help Naruto understand his connection to Kaguya better. He could share any knowledge he has about the Otsutsuki clan. Naruto would probably respect Kakashi even more, as he is one of the few people he can turn to for guidance in this new situation. And with the younger generation of ninjas, they could see Naruto as an even greater hero and look up to him more, which might also put some pressure on Naruto to always be a good example.
When it comes to the other Kage, Naruto's new status as Kaguya's grandson could lead to a mix of reactions. Some might be more wary of him, fearing that he could become too powerful and pose a threat. Others, like Gaara, who has always been Naruto's friend, would likely be more supportive. Naruto would have to work hard to maintain good relations with all the villages, using his new identity not as a means of dominance but as a way to promote peace and cooperation among all the ninja clans.
His relationship with Hinata could change. She might be in awe of Naruto's new connection to such an ancient and powerful being. Naruto could also be more protective of her, fearing that his new enemies might target her to get to him. With his friends like Shikamaru and Kiba, they might look at Naruto in a different light, seeing him as even more of a mystery and a source of great power. They could be both more cautious around him and more eager to help him in any new battles or challenges.
At first, it might be one of suspicion. Naruto would be wary of Kaguya's power and her past as a sort of villain. But as they face challenges together, they could start to respect each other. Naruto might see the good in Kaguya that was buried under her past actions, and Kaguya could come to admire Naruto's tenacity and his strong sense of justice.
At first, it could be a relationship full of tension. Naruto would be cautious because of Madara's past actions. But as he gets to know the grandson, he would see that he is his own person. They might start to respect each other. Naruto would offer his wisdom and experience, while the grandson would offer a fresh perspective.
Their relationship might start with Kaguya being instantly drawn to Naruto because of his strength and positive energy. But as her yandere side kicks in, she becomes over - possessive. Naruto would be confused at first, but gradually try to understand her.
He might be more laid - back. Naruto was always hyper - energetic and eager to prove himself. His grandson, having grown up in a more stable and peaceful era (assuming so), could be more relaxed. He may not have that same intense drive for recognition all the time.
Their relationship could develop through Naruto showing Kaguya the beauty of the modern ninja world. He could introduce her to his friends and family, which would gradually make Kaguya see the value in human connection and change her view on the world.
In a fanfiction, their relationship could develop through shared knowledge. Naruto is curious about the history of the ninja world which Kaguya knows a great deal about. As he asks her questions and she shares her stories, they start to bond. Also, Kaguya could be intrigued by Naruto's determination and his never - give - up attitude. This could lead to a relationship where Kaguya becomes a sort of mentor to Naruto in some ways, while Naruto helps Kaguya to see the good in the current ninja world. Their relationship would then be a mix of learning and mutual admiration.
His understanding of the ninja world would expand. He might become more cautious and calculating in battles, as Kaguya's training could expose him to different strategies. Also, he could develop a more solemn side to his personality, considering Kaguya's own complex nature and the heavy knowledge she might share.
In the fanfiction, Naruto might develop new skills related to Kaguya's power. As he delves into her story and the nature of her abilities, he could learn to control or even mimic some of her powers. This would not only make him stronger but also change his fighting style. His understanding of the origin of chakra and the world itself would deepen, which could lead to him being more of a philosopher - like figure in the fanfiction. He might start to question the cycle of hatred in a more profound way, seeing how Kaguya's actions were influenced by her own experiences. Also, his relationships with other characters could change. For example, if he discovers that Kaguya had some connection to certain characters in the present, he might treat those characters differently or have a newfound respect for them.
He might gain some of Whitebeard's physical strength. Whitebeard was incredibly strong, and Naruto could inherit a portion of that. So he could be even more powerful in hand - to - hand combat. Also, he might get some kind of seismic - sense ability, like how Whitebeard could sense things through the vibrations in the air or ground.
He might have some Egyptian - inspired markings on his body. For example, he could have a small ankh symbol on his forehead or some hieroglyph - like tattoos on his arms. His eyes could also change to a more golden color, similar to how Anubis is often depicted with golden eyes in Egyptian mythology.
