One possible storyline could be that Naruto, as a yokai, has to hide his true identity in the Highschool DxD world. He might get involved in the power struggles between different factions while also trying to fit in at school. Another could be that he uses his yokai powers to help out the main characters in Highschool DxD, like Issei, in battles against their enemies.
A possible storyline is that Naruto's yokai nature gives him a connection to the supernatural elements in the Highschool DxD world that others don't have. He might discover secrets about the world that no one else knows. For example, he could find a hidden place or power source that is related to both yokai and the devils or angels. His presence could also stir up old rivalries as some characters may see him as a threat to the existing power balance.
