I don't know for sure. You'd need to read the novels to find out the main characters.
I'm not entirely sure specifically as I haven't read it in great detail. But generally, it's likely a story with its own unique characters, plotlines, and settings that are developed over the course of the series.
A 'wallbanger novel' is often a type of contemporary romance novel. It usually contains elements like passionate love stories, strong characters, and a good deal of emotional drama. These novels are known for their ability to keep readers engaged with the relationship dynamics between the main characters.
Alice Clayton is a well - known author of wallbanger - type romance novels. Her works are quite popular for their fun and flirty stories.
Another main character could be Professor Grey. He is an older, wiser figure who has a lot of knowledge about the secrets in the series. He often provides guidance to the younger characters, but also has his own secrets that are gradually revealed as the story progresses.
Maybe there's a financial advisor or a mentor figure in the story. This character could play a crucial role in helping the millionaire manage their wealth, make important business decisions, or even in guiding them through personal and moral challenges that their wealth has brought about.
The main characters include Kamijou Touma, who often finds himself in the middle of various conflicts due to his unique ability to nullify any supernatural power. Index, as mentioned before, is another important character. Her knowledge and her relationship with Kamijou are central to many storylines. And then there's Mikoto Misaka, a powerful electromaster. These characters, among others, form the core of the 'toaru series novel' and their interactions, goals, and growth are what make up the fabric of the story.
In the 'kinnporsche series novel', the main characters are Kinn and Porsche. Kinn is likely to be a complex character, perhaps involved in some sort of power - based family or organization. Porsche, in contrast, might have his own unique traits and background. Their interactions and the development of their relationship are what drive the story forward.
The main character is Boogiepop. There are also other important characters who interact with Boogiepop in different ways, but I can't recall all their names at the moment.
I'm not sure exactly as I haven't read this particular series in detail. But usually in a prophecy - based novel, there is a hero or heroine who is central to the prophecies. Maybe a young person with some special abilities.
Not having read the 'nitiman the series novel', I can only speculate. Nitiman must be a main character. There may be a mentor - like figure who guides him, or a group of comrades with whom he shares his adventures. There could also be antagonists who oppose Nitiman's goals, creating conflict and driving the story forward.
