Who are the important new characters in Mushoku Tensei Volume 9 Light Novel?

I'm not sure which new characters are introduced in this volume specifically. It could be characters related to the new areas or story arcs that start in this volume.

I'm not entirely sure as I haven't read Volume 8 in detail yet, but there could be some characters related to the new places Rudeus visits. Maybe a new mentor figure for his magic studies.

There may be a new teacher figure who plays a crucial role in the protagonist's magical training. This character could bring in new techniques and knowledge.

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.

The protagonist is surely an important character. His actions and decisions drive the story forward. There may also be his friends or allies who play crucial roles, like those who have been with him since the earlier volumes and continue to support or challenge him in this one.

There's Sylphiette. She is one of Rudeus' friends and later love interests. She has her own growth arc and her relationship with Rudeus is a key part of the story. Eris Boreas Greyrat is another important character. She is a noble and has a feisty personality. Her interactions with Rudeus are full of energy and she also plays a role in his development.

There might be a new mentor - like figure who has a unique perspective on magic. Maybe there's also a new rival, someone who challenges the main character in his pursuit of knowledge or power. These new characters would add more depth and variety to the story.

The protagonist is of course very important. His actions and decisions drive the story forward. His family members also play significant roles. For example, his father who has his own set of values and expectations for the protagonist. And his friends, like those he meets during his studies or adventures, are important as they support him or sometimes oppose him, which creates interesting dynamics.

The main character is Rudeus Greyrat. He is a NEET in his previous life and gets reincarnated in a new world in this volume.
