Also, Demiurge, with his intelligence and strategic thinking, is important in the events that unfold in Volume 1.

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.

Probably the members of Ainz's guild are important. They might be involved in his plans or have their own sub - plots in Volume 17.
