Well, 'Kumo desu ga Nani ka' is a light novel. The story follows the adventures of a reincarnated girl in a fantasy world from the perspective of a spider. The light novel format allows for in - depth exploration of this unique concept. It has a dedicated fan base who enjoy reading about the complex world - building and character development in the light novel form.
There's no clear indication that it's popular. Just from the title alone, it's not a name that immediately rings a bell as a super - popular light novel. But it could be a hidden gem that only a small group of dedicated readers know about. Maybe it has a really unique story that just hasn't caught on with the mainstream yet.
Well, in light novels, they often have unique settings and characters. 'Kumo desu nani ga' could potentially be a story set in a fantasy world where 'kumo' plays a significant role. It might involve a journey of a kumo - like being, facing various challenges and making friends or enemies along the way. There could be elements of magic or special powers associated with the kumo concept.
One difference could be in the editing. Light novels usually go through more professional editing compared to web novels. So, the 'Kumo desu ga Nani ka' light novel might have a more polished writing style.
Since I haven't read'murabito desu ga nani ka web novel', it's hard to give a detailed account. However, from the title, it could be that the story centers around a character who identifies as a'murabito' (a regular person). The 'nani ka' part implies that there is something going on with this person. It could be that they get involved in a strange or unexpected situation in the web - novel's world, like uncovering a mystery or facing a unique challenge.
I'm not entirely sure as it could be a very specific or relatively unknown novel. It might be about an isekai (another world) setting where there are monsters (mamono).
You could try looking for it in specialized Japanese or international bookstores that carry a wide range of novels, especially those with isekai themes.
I don't know the exact plot as I haven't read it. But generally, in an isekai - type novel, the protagonist is often transported to another world and then starts some kind of adventure. Maybe in this novel, the main character, after arriving in the other world, begins their journey as a 'joushu' (which might be some kind of role like a lord or leader).
This novel seems quite specific. If it's a Japanese novel, perhaps looking into Japanese - language bookstores or online stores that focus on Japanese literature could be a good start. You might also want to search for any fan - made translations or summaries on the Internet, but be aware of the legality and accuracy of such sources.
