Unfortunately, without having read Danmachi Volume 19 Light Novel in full, it's difficult to name the new characters precisely. But typically, new characters in the series are designed to bring fresh challenges and interactions. They could be powerful adventurers that Bell and his friends have to team up with or compete against, or they could be some strange creatures from the deeper parts of the dungeon with their own motives and behaviors.
I'm not entirely sure about all the new characters in volume 14. But sometimes new characters are introduced to either help or hinder the main characters' progress. They could be other adventurers, or perhaps some mysterious figures related to the dungeon's secrets.
There might be new adventurers who join Bell's party temporarily or become their rivals. These new characters could bring in new skills and perspectives. Maybe there are also some characters from the background of the dungeon world, like merchants or informants who have important information related to the new challenges in Volume 8.
I'm not entirely sure about brand new characters introduced only in Volume 7. But of course, Bell Cranel remains very important. His growth and development are central to the story. And Hestia, as his goddess, is always significant. Other existing characters like Ais Wallenstein also continue to have an impact on the events in this volume through their interactions with Bell.
Since I haven't read volume 14 in detail, I can't say for sure who the new characters are. But it's possible that there are new members of a guild or organization that Ainz has to deal with. These characters could bring new dynamics to the story, whether they are powerful warriors, cunning mages or something else entirely.
Since I haven't read Konosuba volume 17, I can't say for sure. However, in previous volumes, new characters were often introduced to add more variety to the story. They could be allies or antagonists. In volume 17, new characters might be from a different part of the world in the Konosuba universe, like a powerful wizard from a far - off land or a sneaky thief from a seedy underworld.
I'm not entirely sure without re - reading it specifically, but there may be some minor characters introduced to add more flavor to the story, such as local villagers or new adventurers in the area.
I'm not entirely sure without reading it specifically, but likely Bell Cranel would still be one of the main characters as he is central to the series.
Bell Cranel is surely one of the important characters as he is the main protagonist. His actions and growth are central to the story.
Since I haven't read this particular volume, it's hard to say for sure. However, new characters might be introduced to represent different factions in the story's world. For example, they could be from a secret organization or a far - off land that has its own motives and goals, which will then interact with the main character and his group, either helping or hindering their progress.
I'm not entirely sure which new characters are introduced in Volume 12 specifically. But it's common in the series for new characters to be related to the main character's new adventures or challenges. They could be fellow students if he's at a new school, or locals from a new place he visits.
