Yes, it can be. The idea of Naruto, a well - loved character, in a romantic relationship with Amaterasu, which has its own significance in the Naruto universe, can attract a lot of fans. Many fanfiction writers like to explore unique pairings, and this one offers a chance to blend different aspects of the Naruto lore in a romantic context.
One common theme is power adaptation. Naruto has to adapt his ninja powers in the DxD world which has its own set of rules. Amaterasu, being a powerful ability, often becomes a focus in terms of how it can be used or controlled in this new world.
Obviously Naruto would be one of the main characters since it's about him being the son of Amaterasu. Other likely main characters could be his friends like Sasuke and Sakura. They would play important roles in Naruto's journey as he discovers and deals with his new identity.
Well, a frequent theme is the discovery of each other. Naruto might stumble upon Amaterasu in some way, and they start to understand one another. Also, the theme of forbidden love often pops up. Given their different natures and the fact that such a relationship might not be accepted in their respective worlds, it can add an element of drama to the story. Additionally, there could be themes related to sacrifice, like one of them having to give up something for the sake of the relationship.
Sure, there are probably some out there. Some fanfiction writers like to create unique and unexpected pairings. For Naruto and Amaterasu, it's a rather interesting concept as Naruto is a ninja with his own story arc, and Amaterasu is a powerful entity in the Naruto lore. These fanfictions might explore how such a relationship could develop, perhaps starting from an encounter where Naruto discovers something unique about Amaterasu and a bond gradually forms.
One common theme is the clash of different powers. Naruto has his own set of abilities, and Amaterasu has her significance. Writers often explore how their powers interact and complement each other in a romantic relationship. Another theme could be the discovery of new aspects of the Naruto universe. Since Amaterasu is not a character directly involved in Naruto's main story in the original series, it opens up new areas to explore.
Perhaps a story where a character from the Naruto universe, who has a connection to Amaterasu, travels to the Young Justice world. There, they meet a character who has a similar power but in a different form. They exchange knowledge about their powers and together develop a new technique that combines the elements of both their abilities. This new power could then be used to save both worlds from a common threat.
The 'naruto blessed by shinigami fanfiction' might center around a situation where Naruto has a connection with the Shinigami. It could involve Naruto being sent on a special mission by the Shinigami or having to face challenges related to this newfound blessing. For example, he could be dealing with the consequences of having such a powerful entity's blessing, like other characters being jealous or him having to learn how to control the new powers that come with it.
Perhaps a powerful demon that has a grudge against the power of Amaterasu. It targets Naruto because he is the one who seems to be getting closer to Amaterasu. The demon could be from an ancient time when Amaterasu was first used to seal it away, and now it's back to stop Naruto from fully understanding and using Amaterasu.
Apart from Naruto and the Shinigami, there could be other characters from the Naruto universe. For example, Sasuke might be involved. He could be either jealous of Naruto's new blessing or he could end up being an ally in Naruto's journey with this new power. Also, Kakashi could be there to guide Naruto in understanding and using the power given by the Shinigami. Maybe there are also some original characters created specifically for this fanfiction that are related to the Shinigami's realm or have some connection to Naruto's new situation.
