I'm not entirely sure as I haven't read it thoroughly, but generally, light novels often involve unique worlds, characters with special abilities, and complex storylines. It might be about a hero's journey, perhaps with elements of magic, adventure, and self - discovery.
It's mainly about the adventures of the protagonist. He embarks on a journey filled with challenges and growth. He has to face various foes and overcome many difficulties in a fantasy - like world.
I'm sorry I don't know the specific main characters in this light novel. But typically, in a hero - themed light novel, there would be a protagonist who is the central figure in the story, and there might be side characters like friends, mentors, or rivals who play important roles in the protagonist's journey.
Another option could be to check out some specialized light novel websites. However, make sure they are legal in your region. For example, BookWalker is a well - known platform that offers a variety of light novels, and it might have 'mushoku no eiyuu'.
Hard to say. It could be on hiatus, but without concrete information, it's difficult to give a definite answer. Try following the mangaka's social media or the manga's official website for the latest.
