Who are the main characters in 'poisoning the world novel'?

I'm not sure specifically as there could be many novels with this name. It might be about a character or group that has the intention or action of 'poisoning the world' in a metaphorical or literal sense, perhaps through spreading harmful ideas, substances, or causing chaos on a large scale.

One common theme is environmental degradation. The world is often shown as being poisoned by pollution, waste, or some sort of ecological disaster. For example, the air might be unbreathable or the water undrinkable.

I'm not entirely sure if it's a widely popular light novel genre. Some light novels with rather extreme or edgy concepts like 'poisoning the world' can gain a dedicated following, but they often don't reach the mass popularity of more common genres. It could be that the nature of the theme is a bit too dark or complex for the general light novel reader.

Without having read the 'the world in 9 1 2 novel', it's impossible to accurately name the main characters. However, if we assume that the numbers 9, 1, 2 are related to the characters in some way, perhaps there are nine siblings and one of them, the firstborn (represented by 1), has a special relationship with a character who is an outcast or different in some way (represented by 2). But again, this is just wild speculation.

I'm not sure specifically which 'poisoning world novel' you are referring to. There could be many novels with themes related to a 'poisoning world' in different genres. It could be a post - apocalyptic novel where the world is poisoned by pollution, chemicals or some sort of dark magic. Without more context, it's hard to recommend a particular one.

Typically, there is a central protagonist who is the focus of the story. There may also be side characters like a wise old wizard or a brave knight.

I don't know specifically as I haven't read it. But they could be ordinary people who get drawn into the secret world, like a young adventurer or a curious scientist.

I don't know since I haven't read it. But it could have a brave hero or heroine as a main character who is involved with the heart of the world in some way.

I'm not sure specifically as I haven't read this exact Circus World Novel. But generally, there could be the ringmaster as a main character. He's in charge of the whole show and has a lot of authority. There might also be a star acrobat, a young and talented performer who is the center of attention during the shows.

Since I haven't read it, I can't say for sure. But often in a novel, the main characters are those who drive the story forward, so it could be a protagonist who is on a journey to discover the 'world of difference' and some secondary characters who either help or hinder this journey.
