An Isekai Gone Wrong

Looking outside the humongous windows showed the dark blanket of the night, the bizarre two moons in the sky were the only light shining upon the quiet, vast forest, making everything look almost idyllic, that is of course if one was originally from this world and was was using the night to finally rest to once more wake up and repeat their normal lives.

That was of course the difference between the creature currently looking outside the window and the rest of the population living some distance away from such tenebrous looking castle; the key word being creature, after all, it was hard to think of the being currently using the castle as residence as human, due to the red horns, tail and bat wings growing out of their body.

Taking their sight away from the window, the demon-like creature once more returned to the desk that they had used for the last several days and continued their study, the stylish glasses once more present on their face. Sitting down, they grabbed a heavy looking book and continued reading, trying to understand their situation.

It had been quite the tedious, but exciting days since the creature had found themselves upon this world, days that they used to find out everything that they needed to finally understand their situation. After all, not everyday one was transported to another universe after dying, but that usually happened in stories, not to real people, but alas, here they were and they had to make sense of all the insanity.

As they continued to read, their mind was pulled backwards in time, to the moment everything had changed, to the moment the huge billboard had crumbled under their own weight and at the last moment, he had pushed a woman out of the way, just before being flattened and apparently dying instantly.

Next thing that happened they had awakened naked in the middle of an empty room made out of stone, with dozens and dozens of books, vials filled with ingredients, jars full of ingredients. They had opened their eyes and found themselves drenched in a blue viscous liquid, with no idea what had happened, confused and alone.

The moment they had decided to look around, sure that they weren’t dreaming, they had to get used to their new centre of mass and that’s when they found out how different they were now. They had stopped being male, now their… her body had become female, and what a body it was, with huge, bouncing breasts overflowing her hands, soft as marshmallows and tipped with cherry coloured nipples. The rest of her body was equally impressive, with long legs, dainty hands and curves everywhere, but the most surprising things were the extra stuff that came with the body, like the two sets of horns, one set on her forehead, thin and strong, while the other seemed almost draconian; she also had a spade tipped tail and two big and strong wings growing from her lower back.

She was a sex bombshell, and one that had been transported to another world at the moment of their , but what exactly had happened? Well, once she was able to once more find their balance, something that was a lot easier once she stopped thinking about every single step, they found out that their body was deceptively strong, way too strong to be a normal human.

After trying to get accustomed to her new body, she tried to find anyone else on the obvious fantasy castle, but besides armour, weapons, jewellery and other paraphernalia left forgotten everywhere there was nobody, as if they had all disappeared suddenly; could it be that her summoning and the disappearance of everyone in the castle was linked? After finding some clothes, albeit a bit too tight in some places and completely loose in others, she was ready to find answers to all the questions she had, after all, she was sure that she had died.

All the stories she had seen about situations like this always showed the person or creature responsible for such actions, then they gave the mission or the reasons, but not this time, so maybe it was never like that or there was something very strange at place in here, because the rather macabre decorations, the dark symbols and her current looks did not say heroes or defenders of the innocent.

The answer was found in the enormous collection of books that she had found in several places, among them the main laboratory, the place where she had woken up, there were also other places, like the main library in the castle, or even several other places, one of them clearly the bedroom of the demon that had commanded that place, but all of them were gone, only trinkets left behind.

It had took her a full day, but since apparently she didn’t feel hunger, she had a lot more time to see what exactly was going on with her and she had found the answer in one of many esoteric and clearly dangerous books, the kind of book that said ‘look at me, I’m clearly evil’; it was weird, the text was clearly written in another language, but she was clearly able not only to read, but comprehend the content. Opening and studying other books showed the same thing; she was able to count upwards to 15 different languages, but all of them were comprehensible. What was going on?

Finally, she found out what was going on after reading books specifically about demons, and with them and what seemed to be notes and research that she had found in the laboratory, a clear picture was finally forming. She was now what was called a Succubus Queen, the ultimate form of the female demons that roamed the world called Diamat; demons hailed from another dimension, but they had been summoned long time ago and they now called this place home, much to the lament of the mortal races, but what truly surprised her was the information of why she found herself in this world.

Something pulled her from her ruminations and studies, it was a sound outside, something that her fine senses picked immediately, it wasn’t only the sound of birds flying after being disturbed, it was something else, something that she had only read about, something that told her other human beings were approaching, she had to prepare, so closing the book she had been reading and extinguishing the candles in the reading room with only a slight move of her hand, the new Succubus Queen began a series of events that would forever change the world of Diamat.
