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.
Well, 'Sore wa marude amagasa no you ni web novel' could potentially be a very creative or abstract description. 'Amagasa' might be used metaphorically here. It could imply that the web novel has some characteristics similar to an amagasa, perhaps in terms of being protective (like an umbrella protects from rain) in the context of the story, or it could be about the shape or style being reminiscent of an amagasa in some way.
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.
It could imply that even a humble or unassuming swordsman (assuming 'kensei' means swordsman) is still the strongest in the context of the web novel. Maybe it's about a character who doesn't seem extraordinary at first glance but has hidden, overwhelming power.
One example could be a web novel where the story is centered around a traveling merchant. The merchant has an amagasa that he uses not only to protect himself from the elements but also as a sort of trademark. The amagasa becomes a symbol in the web novel, just like the phrase'sore wa marude amagasa no you ni web novel' implies a connection. The amagasa might be described in great detail, and its presence affects the mood and the flow of the story. It could be that the color of the amagasa represents the merchant's mood, or when he loses the amagasa, it marks a significant turning point in the story, showing how integral it is to the web novel, similar to the connection the phrase is trying to convey.
This phrase seems to be related to a web novel. 'Jimina ken sei' might be a proper name or some sort of special term in the story. The part 'sore demo saikyou desu' implies that despite certain circumstances, something or someone is the strongest. It could be that in the web novel, the character or entity named Jimina ken sei has some sort of unrivaled strength or ability, whether it be physical strength, magical power, or some other form of dominance within the story's world.
It can introduce an element of surprise. The plot can revolve around the other characters gradually realizing the true strength of the 'jimi na kensei'.
It's a visual novel that likely tells a unique story. Maybe it involves themes like dreams and stars as suggested by 'chiisana hoshi no yume' which could mean 'the dream of a small star'. However, without playing it, it's hard to say exactly what it's about.
