If any readers think this pace is slow, then I encourage you to read the novel,, which have excellent translations and are keeping up with the latest chapters.
The reason this pace is a bit slow is because there is a lot of explaining people need to do regarding their thought processes, I like it because it makes the story feel concrete.
In the future, so much more will happen, and Harold will see many changes in sceneries, so do not worry about this being a slow political manga forever.
