On a more emotional level, it could mean a lot to Naruto and Konan themselves. Naruto, who has always been searching for family, would gain a new family member. And Konan, who has lost so much, might find a new purpose or connection through this relation. It could lead to some really interesting character development for both of them.
Perhaps they start off as enemies, not knowing their relation. But as the story unfolds, through various battles and interactions, they begin to suspect that there is more to their connection. It could be that they both have a strange mark on their body that is only found in their family, which leads them to uncover their relation. And then they have to decide whether to continue as enemies or join forces.
One implication is a change in his moral compass. Jashinists are often associated with dark and violent practices in the Naruto universe. So if Naruto is a Jashinist in fanfiction, it means he could be involved in actions that go against his original kind - hearted nature.
One implication is that his power levels would be off the charts. Since the Kyuubi is an extremely powerful entity, Naruto would have a whole new set of abilities.
One implication is a change in his combat style. Instead of relying on his shadow clones and Rasengan, he'd use puppets for attacks and defenses. It makes him more versatile in battle.
One possible plot could be that they accidentally get caught in a jutsu that causes Konan to become pregnant. Naruto, being the responsible person he is, decides to support her fully. They might face challenges from their respective villages as their relationship was unexpected. Konan may have to deal with the physical and emotional changes during pregnancy while Naruto tries to protect her from any harm.
One implication is a change in his status. He'd have more political power and influence. For example, he could use his position to form alliances between the Whirlpool and Konoha more easily.
One implication is a change in his status. He would be seen as royalty in the context of that fanfiction. This might mean he has certain privileges and responsibilities.
Well, it's a very strange implication. It would completely distort the Naruto story. Naruto's world is about ninja clans, rivalries, and personal growth. If he's suddenly the Biblical God, it would mean a shift from his ninja - like qualities to god - like omnipotence. His relationships with his friends would also change as he'd be in a much more superior position. It's also a bit disrespectful to the religious connotations of the Biblical God as Naruto is a fictional character from a non - religious source.
It could mean a major change in the Naruto universe's cosmology. If Naruto is the God of Death, then concepts like the afterlife and reincarnation might be re - defined according to the fanfiction's plot. Also, his enemies would have to face a much more powerful adversary, which could lead to very different battle scenarios. The whole ninja world would be forced to re - evaluate their understanding of Naruto and his place in their world.
The implications are far - reaching. Firstly, his power level would skyrocket, allowing him to perform feats that were previously unthinkable. This would also change the power balance in the Naruto universe. Politically, villages might try to ally with him or try to control him. Emotionally, Naruto himself would have to grapple with this new identity. He might struggle with the responsibility that comes with being a 'god'. His friends might have mixed feelings too. Some could be proud but also feel a bit of a distance now that he has such a lofty status. It would completely transform the story and the way we view Naruto and the world he inhabits.
