Another is 'The Road' by Cormac McCarthy. This novel presents a post - apocalyptic world filled with desolation and despair. The father and son's journey through this cruel world, facing starvation, cannibals, and the harsh environment, really reflects the cruel side of the world.
It could be about a character who is lost in a world full of hardships and challenges. Maybe the story follows their journey to find themselves or a way out of this cruel world.
The main theme often revolves around the coexistence of cruelty and beauty in the world. It might explore how characters navigate through difficult situations and still find elements of beauty in life, like relationships or personal growth.
I'm not sure specifically as I haven't read this novel in detail. But usually, the main characters are those who drive the story forward and face the most significant challenges related to the novel's themes.

I'm not sure specifically as I haven't read this novel. But generally, there could be a protagonist who is likely to be the central figure through which the story unfolds. This character might be someone who is deeply affected by the cruel world and has to find their own way to deal with it.
A 'Cruel and Beautiful World Fanfic' might explore the complex themes presented in the original work more deeply. It could focus on the characters' struggles in the cruel aspects of the world while still finding beauty.

Since we don't have much information about the specific 'lost in the cruel world visual novel', we can only guess. There might be a young and naive character at the center, who is the main character. Then there could be some antagonists, perhaps people who have become cruel because of the world they live in and try to make things harder for the main character. There could also be side characters like friends or family members of the main character that play important roles in the story, either helping or hindering the main character's journey in this cruel world.
Survival is a major theme. In many cruel world novels, like 'The Hunger Games', characters are constantly fighting for their lives in a harsh and unforgiving environment.
I recommend "Reborn Queen of the Other World: Looking Down on the World". The female protagonist is the Crown Prince of the War God of a generation. He is vicious, cunning, cold, heartless, cruel, and bloodthirsty. He is below one person and above ten thousand people. After she was reborn in the Western Continent, she once again disguised herself as a man, holding the elements of water and fire, killing the Pope of Light, destroying the Angels of Light, destroying the Temple of Light, opening up a path of killing, collecting magical pets, battle pets, and male pets…I believe this novel will definitely satisfy your taste. I hope you like this fairy's recommendation. Muah ~😗
