I'm not entirely sure which new characters might be introduced in chapter 130. But the main character throughout Solo Leveling is Jin - woo. He's the central figure in the story.
Since I haven't delved into chapter 130 specifically, it's difficult to name any new main characters introduced. But we know Jin - woo is always at the forefront. He might encounter other hunters or beings with unique abilities in this chapter. It could be that an old acquaintance returns with a new mission or goal that ties into Jin - woo's journey. Or perhaps there's a new antagonist that shows up, but without reading it, we can only speculate based on the general nature of the Solo Leveling story.
In Solo Leveling 130, while Jin - woo remains the main character, there might be some side characters that get more focus or new ones that are introduced briefly. However, since I haven't read this chapter in detail, it's hard to say for sure. But typically, the story also features hunters and other powerful beings that interact with Jin - woo, and there could be some of them playing important roles in this chapter as well.
There could be new characters in Solo Leveling Volume 9 novel. It's possible that there are new recruits in the hunter organizations that Jin - Woo is associated with. These new characters could bring in fresh perspectives and new storylines. Maybe there are also some characters from other dimensions or parallel worlds if the story takes a more fantastical turn in this volume, which would add a whole new layer of complexity to the plot.
A mysterious figure also appears. This character seems to have some hidden motives and knowledge about the world of hunters that not even the main character is aware of at first. Their presence adds an air of mystery to the story.
One of the new characters is a young assassin. He is very stealthy and has a set of special skills for killing. He initially appears as an antagonist but later on, there are some interesting developments in his relationship with the main character. There is also a new guild master who brings in new rules and politics to the guild system in the story.
In Solo Leveling Vol 6, there might be some new characters related to the deeper exploration of the gates. However, Jin - Woo remains the most important character. His friends and some of the guild leaders also continue to be important as they interact with Jin - Woo in different ways.
There is also a young trainee who looks up to the main character. This trainee has potential but is also naive in some ways. His interactions with the main character and other experienced characters provide some lighter moments in the story as well as show the growth of the next generation in this world.
I don't have the exact details on Volume 9, but considering the pattern of the series, there could be powerful hunters from other regions introduced. They might come with different fighting styles and powers. There could also be some characters who are somehow related to the ancient history or mystery that the series often delves into.
The main character is Sung Jin - Woo. He is the central figure in the Solo Leveling series, and in chapter 106, he is likely to be the focus as well.
The main character is Sung Jin - Woo. He is the central figure in 'Solo Leveling' and I assume he still plays a major role in the 108th part of the novel.
In 'Solo Leveling 104 novel', aside from Sung Jin - woo, there may be other important characters like his family members. His mother and sister, for example, play a role in his life and can be considered important in terms of his motivation and the emotional side of the story. Also, there are his comrades in the hunter's world who often join him in battles or quests.
The main character is a hunter who is on the journey of leveling up to 99. But I don't know the exact name without more research on the novel.
