Maybe there are some characters from a rival kingdom or a secret organization. They could be there to either oppose or help the Shield Hero in some way. Without reading it thoroughly, it's hard to say for sure.
It's likely that there are new characters who play important roles in the new plotlines. They could be magic users with unique abilities or warriors from a different culture. These new characters might bring new dynamics to the story, whether it's in terms of alliances or rivalries with the Shield Hero and his existing companions.
I'm not entirely sure who the new characters are specifically. But it's possible that there are characters related to new areas the Shield Hero visits.
I'm not entirely sure specifically which new characters are introduced in Volume 6. But it could be characters related to the new areas the Shield Hero explores or those involved in the political or magical aspects of the story.
I'm not entirely sure which new characters are introduced specifically in volume 5. But it could be some side characters that play important roles in the local area where the Shield Hero is. Maybe some people related to the political powers in that region.
Based on the general trend of the Shield Hero light novels, volume 7 may introduce characters who are related to the ongoing story arcs. Since Naofumi is constantly facing new challenges, new characters could be those who hold keys to solving problems or creating new ones. For example, there could be new magic users who have different views on Naofumi's power. Raphtalia and Filo will remain important as they are part of Naofumi's core group. And there could be some authority figures in the world who start to take notice of Naofumi's actions in this volume and interact with him, thus becoming important characters in this part of the story.
It's possible that in this chapter, we might see the introduction of characters related to the local area where the Shield Hero is currently exploring. For example, there could be a local guide or a merchant who has some important information or items for the hero. Or perhaps some new antagonists who will oppose the Shield Hero's progress.
It's a great start to the series. The story in volume 1 sets up the basic premise well. We are introduced to the main character, the Shield Hero, and his rather unfair situation. The world - building is interesting, with different heroes and their roles. The writing style is engaging and makes you want to keep reading to find out how the Shield Hero will overcome the initial hardships he faces.
The most important character is of course Naofumi Iwatani, who is the Rising of the Shield Hero. He's a complex character who grows throughout the story. Another key character is Raphtalia. She starts off as a slave that Naofumi buys, but she grows into a strong warrior and an important part of his team. And then there's Filo, a bird - like creature who also plays a significant role in the story, providing both comedic relief and combat support at times.
There's also Malty S. Melromarc. She is the one who frames Naofumi at the beginning, causing him a lot of trouble. And then there's the King of Melromarc, whose distrust of Naofumi also adds to the hero's hardships. However, characters like Queen Mirellia later play important roles in trying to set things right for the Shield Hero.
The main character is the Shield Hero. There's also Raphtalia, a demi - human who becomes an important ally of the Shield Hero. Filo, a Filolial, is another significant character. And there are other heroes like the Spear Hero, Sword Hero, and Bow Hero.
Important characters include the Shield Hero himself. He has to deal with a world that's against him at the start. Raphtalia, a demi - human, is key. She starts off as a slave but becomes a strong fighter and an important part of the Shield Hero's life. Filo, a magical creature, adds a lot of charm and power to the group. And the other heroes can't be ignored either. Their actions and attitudes towards the Shield Hero shape much of the story's conflict.
Another important character is Glass. She is a strong warrior from another world. Her battles with the Shield Hero are quite interesting as they both respect each other's strength. And then there is Ren Amaki, one of the other Cardinal Heroes, who has his own story arc and interactions with the Shield Hero throughout the novel.
