It might have a more advanced plot. The story could be more complex compared to the previous volumes as the characters have already been established in earlier installments.
In volume 5, it may build on the foundation laid by the previous volumes. The world - building that started in earlier volumes might be expanded further. We might see more of the consequences of the actions taken in previous volumes. For example, if the protagonist made certain decisions in volume 4, volume 5 could show how those decisions affected not only him but also the other characters and the world around them. The character development might also be more advanced. Characters who were relatively one - dimensional in the beginning might have become more complex and multi - faceted by this volume. And the pacing could be different. Maybe it's faster - paced as the story is approaching a climax or a major turning point.
