Well, one key element could be the concept of survival in the isekai world. The characters probably have to face various challenges like finding food, shelter, and dealing with dangerous creatures. Another element might be the relationship with 'goshujinsama', which could be a source of guidance or power in that new world.
I'm sorry, I don't know who the author of 'shoushaman no isekai survival novel' is. There are so many novels out there, and without more information, it's hard to determine the author.
I'm not entirely sure as it could be a very specific or niche novel. It might be about a character named Shoushaman's survival in an isekai world. That usually involves things like adapting to a new and often fantastical environment, facing strange creatures, and maybe learning new magic or skills to stay alive.
The unique premise of the story makes it stand out. A skeleton knight in an isekai world is not a common trope, which immediately grabs the reader's attention.
I'm sorry, I haven't read this light novel in detail. But generally, 'isekai' novels often involve a character being transported to another world. Maybe in this one, the 'maou sama' becomes a 'yuusha' which is quite an interesting concept. It might have unique plot twists and character developments related to the transformation from a demon lord - like figure to a hero.
