I'm sorry, I haven't read it so I don't know the main characters specifically.
Since I haven't read the 'I shall master this family light novel', I can't name the main characters. However, in this type of family - centered light novel, it's common to have a young, determined protagonist, perhaps a girl or a boy who is trying to make their mark in the family. There might also be some authoritative family elders or rival siblings as important characters.
Meng Hao is the main character. He is the one who drives the story forward with his adventures in the cultivation world.
Since it's about surviving with potions, there might be a main character who is either a novice at using potions and has to quickly learn, or an expert who has to rely on their skills in a new and difficult situation. There could also be other supporting characters like a mentor who teaches about potions, or a fellow survivor who teams up with the main character.
It's a light novel that likely focuses on a character's journey to master or take control within a family setting. Maybe it involves family politics, inheritance battles, or personal growth within the family context.
I'm not sure who the main characters are as I haven't read the novel yet.
In addition to them, there are various sect leaders and powerful cultivators who are either allies or enemies of Meng Hao. For example, the elders of different sects who often try to manipulate or oppose Meng Hao as he rises in power and influence in the cultivation world.
The main character is Alex. He is a young and talented star pilot with great ambitions.
Perhaps there is also a mysterious old sage in 'the dungeon master light novel'. The sage could be a source of knowledge for the dungeon master, guiding him on how to improve the dungeon, manage resources better, and deal with the powerful entities that lurk within it. This character could also have his own hidden motives which add to the complexity of the story.
Since I haven't delved into 'Taming Master Light Novel', I'm unable to name the main characters. However, in light novels, the main character often has some unique traits or abilities. There could be a main character in this novel who is an expert in taming or is on a journey to become one. And there may be other important characters around them, such as those who help or oppose the main character in their taming - related endeavors.
The main character is unnamed at first but gradually earns a name as he progresses in his journey to master the gods. There are several antagonist - like gods who oppose him. For example, there is a goddess of darkness who tries to thwart his plans. And on his side, he has a few mortal friends who, though not as powerful as the gods, provide him with emotional support and practical help in his adventures.
Since I don't know the specific 'word master light novel', I can't say for sure. But usually in such novels, there would be the 'word master' as the main character. There might also be a mentor figure who helps the word master develop their skills.
