I'm not sure who the main characters are specifically as I haven't read it. But it's likely that the bored immortal is one of the main characters. There might also be a mortal character who becomes intertwined with the immortal's life and helps to bring some new perspective or change.
Since I don't know the specific 'mortal immortal light novel', I can't say for sure. But it could be a protagonist who is in the process of becoming or is already an immortal while still having mortal qualities.
In the 'Immortal Asura' light novel, the main character is probably the one with the most development. He could be a young and inexperienced asura - in - training at the start, full of potential. There might be an older, wiser asura who acts as a guide or a source of knowledge for him. And then there could be rivals, who are also asuras or beings with similar powers, vying for the same resources or status. These characters would interact and their relationships would drive the story forward.
Perhaps there is a female lead as well. She could be a strong - willed warrior or a magic user. She might start as an adversary of the Immortal King but later become an important ally. Their relationship could be filled with tension, respect, and eventually friendship or something more, which adds an interesting dynamic to the story.
The main character is a cultivator who embarks on a journey of self - improvement and power - seeking.
I don't know for sure. It could be an aspiring young cultivator who is determined to find the immortal sutra.
The main character is clearly the unwanted immortal adventurer. However, in a story like this, there could be a cast of other important characters. There may be a group of adventurers that he initially tries to join but they reject him because of his immortality. Among them, there could be a leader - type character who is the most vocal about not wanting him around. There might also be a mysterious figure who has been observing the adventurer from afar, perhaps with some ulterior motives related to his immortality. Additionally, there could be a local healer in a village he visits who is kind to him despite his situation, and this healer could play an important role in his journey.
The main character is, of course, the Immortal God Emperor. He is a very powerful figure with extraordinary cultivation skills.
One interesting aspect could be its unique take on immortality. It might explore how an immortal character deals with boredom over centuries or millennia. For example, they could show the character constantly seeking new experiences in a world that has become dull to them over time.
Since I haven't read it, I can't say for sure. But it's likely that the main character is the bored gamer. There might also be characters in the other worlds that they meet, like a wise old wizard who guides them, or a fierce warrior who becomes their ally or rival.
Another important character is Sun Rong. She is Wang Ling's classmate and has a special connection with him.

They all contribute to the daily life and comical situations in the story, creating a rich and interesting cast of characters.
