I'm not entirely sure as I haven't read it specifically. But generally, a web novel could be about various things like adventure, fantasy, or the coming - of - age story of the main character.
One unique feature could be its world - building. It likely creates a world that is distinct from our own, with its own rules, cultures, and species. This makes the story very immersive.
Light novels usually have a variety of themes. 'naze boku no sekai wo daremo' might be about a protagonist who feels isolated in their world, as the title could be loosely translated to 'Why is no one in my world?'. It could explore themes of loneliness, the search for connection, and perhaps the character's journey to change their situation.
One light novel that might be similar is 'Sword Art Online'. It also has a complex world - building aspect like 'naze boku no sekai light novel'. Another could be 'Re:Zero − Starting Life in Another World'. It has a unique story with the protagonist facing various challenges in a different world, just like in 'naze boku no sekai light novel'.
I'm not sure specifically as I haven't read this light novel. But generally, it might be about a dilemma between the world and a girl. Maybe it's a story where the protagonist has to choose between saving the world or being with the girl he loves.
You might try looking for it on some well - known online light novel platforms like J - Novel Club or BookWalker. Sometimes, these platforms have a wide range of light novels available for purchase or even for free reading in some cases.
Well, character crossovers are often a cool concept in 'boku o hero fanfic'. Imagine a hero from this universe meeting a hero from another well - known superhero universe. It can lead to really unique and exciting storylines. Also, exploring the villains in new ways, like giving them more complex backstories or motives that make them more than just the 'bad guys' is quite interesting.
