How Does Upper Demon 1 Typically Challenge Heroes In Dark Fiction?

A new world with nearly unlimited possibilities. A system, classes, magic, skills and monsters. Sounds exciting? But for Jin it didn't go quite as he expected nor was there a princess or a Goddess to welcome him to this new world, his only hope was the system he received. Left alone in the darkness, How will he survive when he wasn't human in the first place?

My best friend and I were pulled together into a steamy dark-fantasy romance novel, where we became the Demon King's newest sacrificial consorts. As someone who had actually read the original book, Elodie went pale. After all, this was the raunchiest, most over-the-top novel the two of us had ever read. She grabbed my hand, trembling. "Camille, if I'd known, I never would have wished on my birthday a few days ago to die of pleasure in some gorgeous man's bed. Now it looks like that dream is actually coming true—except the price is my life..." What she didn't notice was the drool sliding down the corner of my mouth. As the highest-ranking succubus, I'd spent years disguised as a human in the modern world, starved of nourishment and all but withering away. Now I'd crossed into a world with no morals and no rules to hold me back. It suited me perfectly. So the moment I laid eyes on the Demon King in front of me—blisteringly hot to the touch and devastatingly handsome—I didn't hesitate for a second. I lunged forward and sank my mouth into his veined, muscled chest. "Sorry, Elodie. A blessing like this, I'm claiming for myself!"

In a world with machines and angels, the main character has to become the strongest to avoid getting killed and discarded.

I found an old quill in an antique shop and decided to buy it since I have always wanted to write with quills. However, as soon as I touched the quill to the paper, I was transported into the book. I wasn't the only one there, though three males who always hide their identities behind masks were in the book with me. They claim the quill belongs to them, and I must return it. Since I refuse, they follow me into every book I go into. One day, I was debating which of my mature books to write when I accidentally spilled the ink onto my book, 1001 Dark Tales. The only way they'll help me out of the book is if I give the quill back, and there is now a fourth. As I go through more of the book with them, I start noticing things. Things I had never planned for in my book, and it concerned me because even though I hadn't written those parts yet, none of the other stories I had used the quill on had ever gone that off track. However, when we tried to leave the book, it wouldn't let us back out. It seems we're stuck in the book until we finish all 1001 Dark Tales.

He is a demon but also he is a fallen angel. After the war with seraph, he lost his love and became a demon with a broken heart, until he met a girl.

He died killing the Demon King. He woke up sixty years too early. Now the monster is a young man. And he is running out of reasons to stay away. --- Lysan Dusk was the hero who saved humanity. He killed the Demon King, ended the war, and delivered the world from suffering, and his reward was betrayal. He wakes up in a young student's body in a dormitory room of a magical academy, and the calender shows that the date sixty years before he was born. The world outside hasn't broken yet. The war hasn't happened. Lysan's plan is to keep it that way by staying completely out of it. Fail his combat exams, spend whatever borrowed time he has left, living a quiet life, where nothing requires him to be a hero. The man who will become the Demon King, the most feared monster in history is still young and beautiful, with pale grey eyes that find Lysan across every crowded room like he is the only person worth seeing. Lysan knows what those eyes will become. He has looked into them across battlefields, spent a lifetime seeing them in nightmares. He never expected it to feel like this up close. Roman is everything Lysan was warned about — magnetic, dangerous, impossible to ignore. Everyone except Lysan, refuses to be charmed, refuses to feel anything at all. But now, he is failing spectacularly at them because Roman keeps finding him. Keeps watching him and making Lysan's carefully rebuilt walls feel like paper. Lysan knows the ending. But for the first time in two lifetimes, he is wondering if the ending can change. If the monster can be loved instead of killed. If staying is braver than running.
