500th Time Reborn, A World Only Known By Women: The Karma System - Chapter 651 From Destruction to Babysitting

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?

“I miss the feudal era very much.” Chen Muyang once said to his friends.

When a friend asked him the reason, Chen Muyang said yearningly: “Because of polygamy in the feudal era, think about it, you can have many wives, you can sleep in different ways every day, and you can sleep together.”

“Cut!” The friends despised them, but their yearning was no less than that of Chen Muyang.

- Description from novelbuddy

On one spring evening when I was eight years old, I, Erica, Duke of Aurelia’s daughter, realized something.

Huh, I have reincarnated into a fantasy world, haven’t I?

Moreover, it was the romance-fantasy girl game that had the reputation of being bloody, 『Liber Monstrorum ~Phantom Beasts and the Winter Princess~』

The face reflected in the mirror was that of the villainess character of that game.

After repeatedly harassing many characters, including the heroine, she would die without exception, signaling the beginning of an event called the bizarre incident. She was a villain who deserved to get the consequences!

—I absolutely don’t want a destiny like that, though?

No, for me who has remembered the memory of my previous life, there would be no such thing.

In my previous life, I was harassed immensely by an irrationally angry yandere man who proclaimed ‘She is absolutely in love with me.’

My cause of death, too, was from being stabbed by another yandere man who I only had talked with a few times……

Now that I have become the haughty villainess Erica, I shouldn’t encounter more misunderstandings like with the previous life’s yandere men anymore, right……?

In that case, it will be fine as long as I deal with the death flags that I may have raised myself.

All right! First of all, before the bizarre incident begins at the Magic Academy, I will strike down the death flags accordingly!!

—Or so I thought, but it seems that I am about to die.

Eeh, how did this happen—!?
