Strongest Survival by Otome Game’s Heroine (LN) - Vol 3 Chapter 15: Intruder

With the marriage of her prostitute mother to the Count, Aria’s status in society skyrocketed immediately. After leading a life of luxury, Aria unfairly meets death because of her sister Mielle’s schemes. And right before she dies, she sees an hourglass fall as if it were a fantasy. And just like that, she was miraculously brought back to the past.

Arthur got randomly transported to another world. Some people would find that terrifying, but not for him, who was tired of his old life; it was an opportunity.

And, after having bad luck all his life, the tide changed.

It was a world of magic where wizards fought side-by-side with their familiars. Arthur got summoned to be one of these so-called familiars.

He was furious. The thought of becoming a pet was not something he liked. Well, that changed when he saw who his master was.

A hot-woman. And, to make everything better, Arthur was inside the Frostpeak Magic Academy, which only had women students.

“This is heaven. All familiars are beasts, but I'm different. I'm a good-looking man inside a place filled with hot girls.”

When he thought his luck could not get better, he unlocked a system that helped him with everything. Of course, he used the system for a greater good, like getting girls.

I woke up in my sleep, and a strange door appeared in my home…Behind every door is a strange world.

In the nightmare world, Jiang Cheng added the news from the strong man to the fat man, and he almost cried when he heard the latter, “If you die here, the whole family will stand upside down and bleed?”

“Is such that.”

“Then I don’t think you are too scared?” The fat man widened his eyes.

Jiang Cheng turned his head and said in a very formal tone: “Because I am an orphan.”

- Description from novelbuddy

On the haunted mountain in the kingdom, they say there lived a witch.

She was born a princess. But even before her birth, the priest declared her to be cursed and demanded her death. They poisoned the mother to kill the baby before she gave birth, but the baby was born out of the dead mother—a cursed child.

Again and again, they tried to kill the baby but she miraculously survived every single attempt. Giving up, they abandoned her on the haunted mountain to die but she still survived on that barren land— A witch

‘Why won’t she die?’

Years later, the people finally had enough of the witch and decided to burn the mountain. But someone arrived to her rescue and took her with him from that burning place, because dying was not her destiny even then.

Draven Amaris.

The Black Dragon, who ruled over supernatural beings, the Devil who no one wished to cross a path with. He hated humans but this certain human girl would pull him towards her whenever she was in danger.

‘Is she really a human?’

The devil named this mysteriously tenacious girl “Ember”, a piece of glowing coal in a dying fire.

This is a tale of the man who brings death and the girl who denies it.
