I'm not entirely sure which new characters are introduced specifically in volume 9. But generally, in the Overlord series, characters like Ainz Ooal Gown remain extremely important. His actions and decisions drive most of the story. The floor guardians such as Albedo also continue to be significant as they carry out Ainz's orders and protect Nazarick. There may be some minor characters from the human kingdoms or other races that are introduced to show the different perspectives in the world.
In Overlord volume 9, a key plot point is Ainz's attempts to expand his influence. He uses different strategies to assert his dominance. There are battles against powerful foes that test the strength of Nazarick. The volume also delves into the backstories of some of the minor characters, which gives more depth to the overall narrative. For instance, we might learn about the history of a certain village that now falls under Ainz's rule. Additionally, the power dynamics between the different floors of Nazarick are further explored, with some guardians vying for more important roles in Ainz's grand plan.
