Demon Lord's Reincarnation

Valdel and the others within the smaller dome of malice saw what happened and was surprised as to how Ren was easily subduing the primordial demon. They couldn't even see how he did it, all they saw was him lifting his hands. Those that have better perception noticed Ren's hand blurring but that was it. None of them was able to witness that first slash, nor the subsequent ones. That one move of his was such a Godly technique that many were in awe. 

'How powerful have you become Ren? How far will you go, will it be in a place that I cannot follow?' Valdel clenched his fist as he was frustrated, his childhood friend that used to be near his level was now moving further away from him. Even though he was always praised as a genius, even though he tried his hardest to keep up, Ren was always ahead of him. Now his back was slowly fading from right in front of him. 'How can catch up to you if you keep on sprinting forward?' 

Valdel wanted more power, for the first time in his whole life he wanted something more than just saving others and becoming a hero. 

...

'Who the f*ck is that b*tch! Why the f*ck is she looking at Ren like that!... Damn it, even though I already know that Ren is very attractive and that he was going to have more women... Even though I know already, even though my head has already accepted it... It wouldn't be so bad if not for every time I see him after he leaves there's always one or two more women. If he gets even more than this maybe he will forget about me... I don't want that to happen! I know Ren would never let that happen, but still, I can't help but feel anxious every time I see a new woman. I need to do something to make me the number one among all.' Lara gritted her teeth as her icy cold eyes stared at Tsukiko.

...

'Oh, so his true name is Ren, that's a rather cute name much better than Kretos...' Henrietta felt Ren's surging mana and smiled with excitement on her face.

'He's more powerful than I expected, I wonder if he would teach me the techniques he just used. Also, I wonder if I could ask him to spare the primordial demon so I could experiment on him. Hmmm, No he doesn't need to spare him but just even a bit of his flesh would work, if possible I want his brain to be intact.' Henrietta looked at Ren who was smiling viciously at Nyarlom and sighed.

'I guess who won't listen to me in his current state. I'll just get whatever I can in the aftermath.' Henrietta was already planning on what kinds of things she could do with the material she would gain from the body of a primordial demon. 

...

'That's Kretos... Well, I guess his real name is Ren, that is what he called himself... Though I do wonder who Kretos was. Ren did say that Kretos died long ago, was he perhaps a friend of his?' As Afeus was thinking he felt Ren's surging mana and looked at the smiling Ren. 

'I already knew he was powerful but not that powerful. What happened to him in the few days he disappeared? Did regaining his memories gave him a boost in power or was he always this strong?' Afeus looked at Ren in amazement. He always thought that Ren was hiding how strong he truly was, but he never knew what were the limits of his strength. Even after fighting against such a strong opponent, the limit of his strength wasn't clarified. It was as if Ren's power was endless. 

...

While Ren and Nyarlom were staring at each other, Haruto was trying to evacuate the survivors. Well not all of them, the system wasn't allowing him to rescue those that have killed. 

[Criminals aren't allowed in the establishment. We must uphold the highest of standards. We must make the establishment as safe as possible. Only paying customers are allowed in the establishment.] 

...

Nyarlom could no longer remain as calm as before as he started to tremble, but he was not trembling in fear, in fact, he got even more excited and started laughing maniacally. 

"Kekekek HAHAHAHAHA! This is the best, you really are the best! Your power, your pride, and that glimmer of excitement in your eyes as you fight, you love the taste of battle don't you?"

"I don't just love the taste of it, I love every part of it. Truthfully this fight isn't enough to satisfy me and was an utter disappointment. Well, this wasn't even a fight since you were no match for me." 

"That's good to hear, that's really good to hear. If you really want to have the battle you crave, then you should allow me to live and wait for me to regain my full power we'll have a fight that will surely excite you." 

"Hmmm, that does sound intriguing. I'm really interested in seeing you at full power, but... You've done too much. If you didn't touch my women then I would have let you leave after I beat you half to death, but now this is where you die." Ren once again raised his right hand and this time he wasn't using two fingers but his whole hand as a blade.

"I see, I see, well since negotiations have failed, I shall take my leave." Nyarlom bowed and was about to scatter and turn into a form mist but before he could do anything, Ren had his left hand open and was slowly closing it. Nyarlom was constricted by an invisible force, as a primordial demon, he knew that what Ren was using wasn't mana, nor was it malice it was something else entirely. 

"There's no leaving for you here. This will be your final resting place. It's rather disappointing I truly did want to fight you at full power." 

"Kekeke Hahaha! That's alright even if you do kill me, my brethren will come out and spread joyous chaos all around. Not only that with your personality and power I'm sure you will be contributing to that chaos. My only regret is that I would not be there to witness it." Even as his end was nearing Nyarlom remained unperturbed. 

"Before I finish you off, can you tell me your name?" 

"I'm the Primordial Demon Nyarlom. I hope everyone remembers my name as they have their nightmares."

"I see... Is that all you wanted to say? If so then even though it was not what I expected I will still thank you for the battle. Goodbye primordial demon, Nyarlom." Ren swung his hand downward and this time everyone could see him do so. A ray of silver light enveloped Nyarlom. As he was being bathed by the light from the fusion of Spirit Aura and mana, Nyarlom was laughing merrily. After a few seconds, Nyarlom's body disintegrated and left no trace behind. 

From that body, a red mist floated out of it, when Tsukiko saw this she immediately shouted. "Ren!" When Ren noticed the red mist it was too late it had already entered his body. 

"What was that?" Ren asked Tsukiko. 

"That was Nyarlom's spirit form. I thought that strike of yours would have destroyed his soul as well, I didn't expect him to be so resilient. Ren, you need to hurry, a primordial demon in spirit form can possess the body of another living being. The first thing he would do is merge your soul and spirit and replace it with his. I know that you're strong, but even you can't train your soul. We can cleanse your soul back in the tree of life, so quickly before he fully merges with your body." 

The moment Ren heard Tsukiko's explanation he couldn't help but laugh a bit. When Tsukiko saw Ren like that she thought that Nyarlom had already succeeded. Seeing the worrying look on Tsukiko's face Ren stopped laughing and spoke. 

"There's no need to worry, if he had invaded my soul that would mean there's no longer any hope for him." 

"Huh? What do you mean? I don't-" Tsukiko wasn't able to finish her sentence as a feeling of intense fear assaulted her. It was as if she had a memory of Ren's soul that she couldn't remember. All she could remember was this intense fear. 

...

Inside of Ren, Nyarlom was on his way to Ren's soul. He already planned for all of this to happen the moment he saw how strong Ren was. Still, after succeeding he was surprised at how easily he was able to invade. 

'Well, it doesn't matter, with such a powerful body in my control nobody will be able to stop me from enjoying all the chaos I want. Oh, there it is, as expected his soul is much larger than a normal human's soul.'

As Nyarlom entered Ren's soul to merge with it he was surprised to appear in a white room with no one there. He was in a physical form which confused him even more. While he was unsure as to what was happening, Nyarlom suddenly felt his back grow cold. He then heard a joyful voice speaking to him. 

"Welcome visitor, I hope you're ready to provide us with a lot of entertainment." When Nyarlom turned around he saw thousands upon thousands of people smiling at him. They were all smiling the same vicious smile that Ren had. He then spotted someone he knew pretty well. 

"That's impossible how are you in here? Y-y-you're the God of battle, death, and victory, Leonard Tranor." 

"Oh, you know me? Oh, that's right, you're a Primordial Demon, wasn't I the one who sealed you guys before the reset? Heh, so you were able to survive the reset because of my seal. How lucky of you guys."

When Nyarlom heard what Leo said he knew that the person in front of him was the real deal. "Then that must mean... I see... I was destined to lose the moment he appeared." 

Nyarlom finally understood what his current predicament was. He looked at the smiling faces of the many incarnations of the strongest mortal soul and sighed, as he was about to experience a fate worse than death.
