There could also be a mentor - like character. Someone who has either been through a similar experience before or has some special knowledge that can help the protagonist in their journey through hell and back. For example, an old wise man or woman who gives crucial advice at key moments.
Perhaps there is an antagonist as well. This character could be the one causing the 'hell' situation in the first place. It could be a person with evil intentions, like a tyrant in a dystopian world or a powerful sorcerer in a fantasy setting who makes life difficult for the main characters.
It's difficult to determine exactly who the main characters are. However, we can assume that there are at least two characters involved in the love story. They could be people from different backgrounds, like one being from a more conservative upbringing and the other from a wilder, more hedonistic side of the 'sin city'. Their differences and similarities might play a big role in the story as they navigate their relationship through the trials of the city.
Since I haven't delved into the 'hoarding in hell novel', it's hard to say for sure. However, it's likely that there is a central character who has the hoarding trait. There may be some sort of guide or mentor figure, perhaps an otherworldly being who tries to influence the hoarder's actions. And of course, there could be enemies in the form of hellish creatures that oppose the hoarder's activities or try to take advantage of their hoarded items.
I don't know for sure as I haven't read it. It could be a group of outcasts or people with troubled pasts.
I'm not sure specifically as there could be many novels with this title. However, generally, there might be a protagonist who is at the center of the 'descent into hell' experience. This could be a flawed character, perhaps someone who has made a mistake or is being forced into a difficult situation.
It's possible that the main character is a fallen angel or a damned soul. There could also be otherworldly beings like demons or spirits that play important roles in the story. Without reading the graphic novel, it's all speculation, but these types of characters are common in stories about hell.
Another possible theme is transformation. The experience of going to hell and back is likely to change a person. In the 'To Hell and Back Novel', the characters may start as one type of person, but through their harrowing journey, they are transformed into someone different, having learned valuable lessons and grown as individuals.
Well, the exact main characters would depend on the specific plot of the 'hoarding in hell light novel'. However, it's common to have a protagonist who is thrust into the hellish world and starts the hoarding journey. This character might be an ordinary person from the real world who ends up in hell for some reason. There could be a mentor - like character who gives some guidance on how to survive and hoard in hell. And there would likely be adversaries, such as powerful hell - born creatures or other humans who have turned to the dark side in hell, all of which play important roles in the story and the main character's hoarding adventure.
I don't know the exact main characters as I haven't read it. But it could have a female protagonist given the title's connotations.
Without having read the 'Ghosts in Hell House Novel', it's hard to say for sure. However, it's common to have a protagonist who is either lured to the hell house out of curiosity or is somehow forced to go there. There could also be a sidekick or a mentor - like character who helps the main character deal with the ghosts in the house.
