Demon Lord's Reincarnation

"Who's there?!" The person shouted at the intruder who got behind it. The person was still alarmed at how someone was able to escape its senses. 

"Oh my, you took over that body without even knowing anything about her. If you were to go out like that everyone would immediately know that you're a fake." When the person heard what the unknown intruder said the person quickly realized that this intruder was somebody that the owner of the body knew. In fact, it would seem that they had an intimate relationship. 

"How am I a fake? I was just surprised that someone suddenly entered my room." The person tried acting as if Irene wasn't possessed. 

"The way you're talking to me is already proof that you're not the real one, but since you like to play this little game, let's play. If you really are Irene you should know who I am." From within the shadows emerged a beautiful golden-haired maiden. 

'This person isn't an elf or a human, she's one of those fakes that called themselves demons. What would a demon like this have to do with an elf? Not only that I can smell the stench of Death on this one, she's alive but at the same time not.' 

"Of course I know who you are, you're my teacher." Irene(?) smiled at the golden-haired maiden as it made a guess. 

"That's correct," The golden-haired maiden smiled back. When Irene(?) heard that it was correct it almost sighed in relief. Yet the moment its muscles loosened she felt that its legs were being frozen. As Irene(?) was about ready to used spell words, a block of wind had covered her mouth making it unable to speak nor breathe properly. Irene(?) then tried using its hands, but rocks had encroached both of its hands. Irene(?) was fully detained it wanted to use no chant spells but against someone like this demon in front of it as its opponent, doing so was near impossible. 

'I got no other choice I need to change hosts.' The moment the one possessing Irene's body thought of that, it tried to detach itself from Irene's body but it quickly found out that it could not. It then saw the Golden-haired maiden smile mischievously. 

"You know my student has never called me teacher before, she always called me master or my esteem master. The way you looked and talked to me was all wrong from the start. The moment Irene would see me she would usually do a dogeza but you actually looked at me directly. Well anyway, there are a lot of flaws in your acting, don't you think so, Primordial Demon?" 

When the primordial demon heard what the golden-haired maiden said it was surprised. Time had eroded their myths, and they weren't even spoken of as legends nor were they part of any fairy tales. They have long been forgotten in the annals of time. The only beings that could remember them would be the ancient races of deities, dragons, and the high elves. 

The only other being that knows of their existence was the ancient human hero that has been guarding their prison for a few millennia. Noticing the shocked expression of the primordial demon possessing Irene, the golden-haired maiden's mischievous smile grew even wider. 

"You must be thinking how do I know about you senpai. You are one of the original demons, or to be more precise actual demons. Unlike us who came after, we were simply called demons but the truth was we were either humans that evolved differently or monsters that gained wisdom. The humans simply called us demons since they feared us, but in the back of their minds, they were thinking of you guys."

The Golden-Haired maiden slowly walked up to the detained Irene(?). She then eyed Irene(?) from head to toe while muttering something under her breath. 

"While I was trying my best to save myself, the Giant Tree Jubokko had shared glimpses of its memories with me and I came to gain knowledge about you guys. Well to you guys the tree might have been called a different name. That's the problem when an era ends and a new one takes root, the name changes all the time. The Giant tree Jubokko is what we used to call it during the era of demons but in this era the era of humanity's dominance they call it the world tree. But its name during your time was something different Hrl bnzl hgll or in the current tongue the life tree." 

When Irene(?) heard the golden-haired maiden speak the old tongue it was surprising but when Irene(?) heard her say the life tree it was shaken to the core.

Now that Irene(?) knows that the life tree still exists it was imperative that it should escape and tell the others. Irene(?) wanted to make the body it was possessing explode and then after it was free it would possess another individual and flee the kingdom. 

Yet as it was about to execute its plan he noticed that it could no longer circulate its mana. It then looked at the Golden-Haired maiden who was smiling ever so brilliantly. 

"You know I learned quite a bit about you guys from that tree. I was truly curious about what true demons were like, but after seeing you I'm quite disappointed, you're just a parasite. Though I guess not all primordial demons are like you, the others should still have their true bodies."

Irene(?) grew incensed when it heard what the golden-haired maiden said. A lowly fake demon was telling it that she was disappointed. Irene's(?) body started to look like it was burning, something was about to happen. Yet despite the situation, the golden-haired maiden continued to look calm as if nothing was happening. 

"Well, it was kinda fun messing with you, but seeing how easily you're provoked and how easily you got caught in my trap makes me think that the primordial demons aren't really such a big deal."

The golden-haired maiden tapped Irene's(?) forehead and out came a red mist. Once the red mist came out of Irene's body, the golden-haired maiden freed the unconscious elf. The red mist tried to flee but was blocked by an invisible barrier. 

"This was a rather interesting encounter, but the game is over." As the golden-haired maiden was about to end the other party's life, the primordial demon spoke. Now that it was free from the body of the elf, the primordial demon felt a bit better. 

"Hahaha nice one my kohai however, even if you beat me nothing will change. You must never underestimate us primordial demons, as long as chaos and fear exist we will exist, and we will grow stronger. At this moment we haven't even regained a quarter of our true strength, but once that gatekeeper dies we will once again create joyous chaos. The era of man is about to end, it will once again go back to the era of true demons. Well, this doesn't really matter to someone like you who's already dead." 

"Let me tell you one last thing before you go senpai. Even if what you say comes true, I don't think you'll ever win. Seeing as that idiot who loves battle still exists, he with that vicious smile on his face will annihilate all of you." The golden-haired maiden shrugged her shoulders as she destroyed the red mist in front of her.
