I'm not entirely sure as I haven't read it specifically. But generally, a light novel in the context of 'netoge' (which might refer to online games) could be about various things like the adventures of characters within the game world, their relationships, and how the virtual and real worlds interact.
Perhaps there is a lead character who is initially a loner in the online gaming world. Then he meets a mysterious girl ('yome') in the 'netoge'. There might also be his friends in the game, like a guild leader or a skilled gamer friend who play important roles in the story, either supporting or challenging the relationship between the main character and the 'yome' character.
Another theme might be identity. The idol has a public identity as a popular figure, but also has this secret virtual - world relationship, so there could be exploration of different identities. And also, the theme of virtual vs. real might be present, as it bridges the gap between the online game world and the real - world idol industry.
The 'netoge no yome ga ninki idol datta ken light novel' might explore the concept of how the two different worlds, the netoge (online game) world and the idol world, collide. Maybe the main character has to deal with the fact that his virtual wife is now a public figure. It could be filled with comical situations, like trying to keep their relationship a secret or dealing with the idol's fans.
Since I don't have detailed knowledge of this light novel, I can only make general assumptions. It may tell a story in a fantastical setting. There could be a group of characters, each with their own personalities and goals. The plot might revolve around the characters' attempts to achieve something, perhaps related to their dreams or the future of their world. And it may also explore different cultural or social aspects within the fictional universe of the novel.
Online platforms like Amazon or Barnes & Noble could be good places to search. They usually have a wide range of books, including light novels. Also, some dedicated Japanese book import websites might carry it.
Perhaps her physical appearance. The 'ookii' might imply that she has some distinct features in terms of her looks that set her apart from other characters.
Yes, I do. The characters in light novels can be really interesting, and if the ookii onnanoko has a unique personality or story, it's easy to like her.
