What could be the plot of a Naruto and Rias fanfiction involving Rias' sick brother?

One possible fanfiction idea could be that Rias' sick brother is a key factor in a power struggle within their supernatural world. Naruto, being an outsider with his own set of skills and values, could get involved. Maybe he forms an alliance with Rias to protect her brother from those who would use his illness to their advantage.

One possible plot could be that Naruto, as Rias's brother, brings his ninja skills to the world of High School DxD. He might use his jutsu to protect Rias and her peerage from various threats, like the devils from other factions or rogue exorcists. And along the way, he could also teach some of his ninja techniques to the members of Rias's peerage.

The plot might involve Naruto trying to adapt to the new environment of being related to Rias. Since he has his own strong sense of justice from his ninja world, he could conflict with some of the more underhanded tactics in Rias' world. But in the end, they work together to overcome difficulties. For example, when facing a powerful enemy that neither of them could handle alone, they combine Naruto's ninjutsu and Rias' devil powers to defeat it.

Well, it could be that Naruto somehow gets transported to the world of High School DxD and discovers he has a connection to Rias, like being her long - lost brother. Maybe he uses his ninja skills to protect her from the various threats in her world.

Well, in a 'Naruto is Rias' brother' fanfiction, there would be a lot of potential for character development. Naruto, being from a world where he had to fight for his place and for the safety of his village, would bring that same determination to protect Rias and her friends. He might be shocked at first by the devil society's hierarchy and customs, but would gradually find ways to fit in and make changes. Rias, on the other hand, would have a powerful and loyal brother by her side. They could face off against common enemies, like other devils who oppose Rias' ideas or angels who see Naruto as an unknown and dangerous element. The fanfiction could also explore their family backstory, how they were separated in the first place and what it means for them to be reunited now.

The plot could involve Naruto finding himself in a situation where he has to interact with Rias's brother. The brother, being too involved in his own world of power and politics, simply brushes Naruto off as unimportant. Naruto then decides to prove himself not through grand displays of power, but through his kind heart. He helps those in Rias's group who are being overlooked or underestimated, just like he was in his own village. This catches the attention of Rias's brother who starts to see the value in Naruto he had previously neglected.

Well, one possible plot could be Naruto growing up in the world where Rias lives. He might struggle to fit in at first because of his different upbringing in the Naruto universe. But then, he could use his ninja skills and strong will to protect his sister Rias and her friends. He could also introduce some new ninja - like elements to their world, like new combat techniques or ways of training.

Issei could be involved. He might be initially skeptical of Naruto, but as they train together or fight side by side, they become friends. Akeno could also play a part.
