What could be the reasons for a 'naruto is antisocial' fanfiction?

Well, it could be fanfiction where Naruto isolates himself from his friends. For example, a story where he becomes disillusioned with the ninja world and decides to live alone in the forest, shunning all his previous relationships.

One example could be a fanfiction where Naruto turns his back on the village due to being constantly ostracized and becomes a lone wanderer, causing chaos in his own way as he battles his inner demons. He might avoid social interactions and lash out at those who try to approach him, which is quite different from his usual friendly self in the original series.

It could be due to the failure of protecting his village or his loved ones. Naruto has always been about protecting those important to him. If he fails at that, his anger is understandable.

In regular fanfiction, Naruto is often depicted as a positive force in the village, working towards peace and harmony. However, in antisocial fanfiction, he might be at odds with the village. For instance, he could oppose the Hokage's decisions and act independently in a way that is not for the common good. He may not care about the traditional ninja values anymore and instead do things his own way which is not in line with the social norms of the Naruto universe.

One reason could be the fear of losing his friends. Naruto has always been very protective of his comrades. In some fanfictions, he might face a situation where he is on the verge of losing them, like a powerful enemy threatening to kill them all. This would make him afraid as his friends are his most precious things.

In some fanfictions, Naruto might leave the Anbu due to internal conflicts within the organization. There could be corruption or power struggles. Naruto, being the idealistic character he is, would not want to be part of such a messed - up system. He might have discovered some dark secrets about the Anbu that made him decide it was not the place for him.

Well, in the fanfiction, perhaps Naruto realizes that Konoha's politics are too complex. There are always hidden agendas and power plays. He, being a straightforward person, might get tired of all the behind - the - scenes stuff. Also, he may feel that his friends are changing because of Konoha's influence. For example, they might be more focused on the village's reputation rather than their true feelings, which makes Naruto sick of it all.

In fanfiction, Naruto could feel sick due to overusing his chakra. He often pushes himself to the limit in battles and training, and this excessive chakra use might take a toll on his body, making him feel ill.

In the 'naruto rejects rias fanfiction', Naruto might reject Rias because of their different character traits. Naruto is known for his boisterous, positive, and somewhat naive nature. Rias, as a devil in her own story, has a more complex and often manipulative side. Naruto, with his straightforward ninja values, might not be able to deal with or accept Rias' way of doing things. For example, Naruto believes in hard work and loyalty among his comrades, while Rias' actions might be driven more by power plays and strategic considerations within her devil society, which Naruto could find unappealing.

Maybe she wants to keep her real relationship with Naruto pure. Fanfiction can be full of all sorts of wild and untrue interpretations of their relationship. She values what she has with Naruto in reality and doesn't want to be influenced by fictional ideas. For example, some fanfictions might create unnecessary drama or unrealistic scenarios between them.
