There are a few new characters in Overlord Vol 15. Some of them are representatives of kingdoms or groups that have caught Ainz's attention. They come with their own motives and abilities, and their interactions with the existing characters, especially Ainz and his followers, add new twists to the story. For example, there could be a diplomat from a far - off land who tries to negotiate with Ainz, bringing in a different perspective on the power balance in the world.
In Overlord Vol 15, we meet new characters who are crucial to the evolving plot. These characters often have unique abilities or knowledge that either aids or challenges Ainz. Some might be powerful magic users from a hidden sect, or leaders of a small but influential group. Their entry into the story creates more opportunities for conflict and cooperation.
