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.
The main character is undoubtedly Naofumi. He has to endure a lot in this new world. Raphtalia is very important. She is a demi - human girl who was once a slave. Naofumi helps her grow and she becomes an important part of his team. Filo, a Filolial Queen, is another mainstay. She's cute but also a force to be reckoned with in battles. Malty, the Princess, is a character who brings a lot of conflict into the story as she is the source of Naofumi's initial misfortune through her false accusations.
The main character is the Shield Hero. There are also other heroes like the Sword Hero, Spear Hero, and Bow Hero who play important roles in the story as well. And then there are characters in the new world he is summoned to, such as Raphtalia, who becomes an important ally of the Shield Hero.
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.
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 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.
Well, from what I know about the series, in volume 6, it could potentially focus on the Shield Hero's attempts to gain more power or allies. There might be more political intrigue in the world he's in, like dealing with the different kingdoms and their attitudes towards him. Also, his relationship with his party members might be explored in more depth, such as any conflicts or growth within the group.
It has indeed finished. All the planned arcs and plotlines have been wrapped up, providing a complete reading experience.
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.
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.
