Demon Lord's Reincarnation

"I remember you said that if I become strong enough you'll tell me everything. So do you think I'm powerful enough now? I want to know more about you and your battle against the ORIGIN. It has been so long and the only things I truly know about you are the bits and pieces I hear from the other incarnations as well as those poor souls that are captured into our soul realm. Yet nobody would tell me the full story, no it seems like no one truly knows the full story... So the one who has been praised as the first hero of humanity what is the purpose of your eternal battle?"

The original incarnation looked at Ren and smiled at him gently. Among the various reincarnations of the Strongest Mortal Soul Ren wasn't the strongest like Rei Kuraki or the smartest reincarnation like Cry Loder, he didn't have the best companions like Edge Regius nor did he have the most incredible weapons like Leonard Tranor. Ren wasn't too weak nor too strong, among all the heroic and reckless reincarnations Ren seemed oddly normal.

'Yet, he's the only one who wanted to learn the truth about me, about us... Even Cry Loder who wishes to see the truth of everything never asked me such a question.'

"Hmm, you have indeed grown more powerful than that time you asked for the truth. You might be strong enough to learn a portion of the truth, but if you want to learn everything you need to prove yourself."

"Hoh, then how can I prove myself? Don't tell me that I need to be able to hit you at least once, or are you going to say something that if I can hurt you then you'll approve of me? Well, that's what I usually tell my opponents, but let me tell you now even though I truly want to fight you, and my blood is boiling just thinking about battling the strongest among all these battle-perverted incarnations... But, I understand my worth. At my current level, I won't be able to hit you much less harm you."

The original incarnation chuckled before responding.

"Of course I know that. I already faced every single reincarnation in this realm and even together except for Rei Kuraki, none of you can even touch me. Well, I guess Leonard Tranor can hold on for a little bit because of his greater tenacity... Still, I do understand... That's not the kind of challenge I wish to bestow upon you. At some point, the so called Demi-Gods and I think even the New Gods will be coming to the Sect you're staying at, so if you're able to defeat or repel them, then I can agree to tell you everything I know."

"Then, it's a deal. I will defeat all of those that come just like normal."

"Even though I already know that all of you are this kind of person hearing your confidence in everything you do is really..." The original incarnation shook his head as he smiled helplessly at Ren.

"Anyway, since you're here I guess it's alright to tell you a little bit about my story. Do you want to listen or do you want to wait until you finish your challenge?"

"Well seeing as you're willing to tell me a bit of your story I'm willing to listen." Hearing Ren's answer the original incarnation nodded his head and started to tell a tale.

...

"Back when the ORIGIN first created humanity there was no concept of age. As long as you weren't killed by some accident any human being could live potentially forever. Not only could every human live forever but the planet where humanity was birthed, the world called EDEN was a paradise like no other."

"EDEN had everything humanity needed, and in there humanity flourished. At first, humanity was content with what they had but then they started to wish for something more. Humanity started to create things that never existed before. Seeing the humans create things shocked the Ancient Gods as back then only the ORIGIN had such an ability. Even the Ancient Gods could only control the things that they received from the ORIGIN. Even their ability to create the Old Gods was an ability given to them by the ORIGIN, they did not have the ability to create new things."

"Unfortunately, this was the start of humanity's misfortune. Seeing their ability to create new and wonderful things made the ORIGIN appreciate the humans more than his first creation the Gods. Jealous, the Ancient Gods started to attack humanity with a little plague every now and then. Of course, the Ancient Gods did not go too far as the ORIGIN was protecting humanity, but then after a while the Ancient Gods noticed something."

"Slowly but surely the ORIGIN's attention on humanity was disappearing as he was no longer intervening as much as he did before. The Ancient Gods grew bolder by the day until finally, one Ancient God accidentally killed a human. Of course, humanity pleaded with the ORIGIN for justice but then the ORIGIN did something that no one expected and instead of punishing the Ancient God who murdered a human, the ORIGIN actually annihilated the first humans. After annihilation, The ORIGIN then recycled the souls of the humans and recreated them."

"The madness and jealousy of the Ancient Gods had started to infect the ORIGIN. Every time humanity grew to a certain point the ORIGIN would annihilate and recreate them. The ORIGIN restarted humanity by using the same souls and every time he did so he would cleanse these human souls before placing them back into EDEN."

"At some point in time, a human had somehow remembered the past annihilation. The horror he felt upon gaining this knowledge was enough to drive him crazy. It turns out the paradise of EDEN was no paradise at all, it was just a cage that trapped humanity in an endless cycle of death unable to move forward. He tried to warn the others but no one believed him, and once again humanity was cleansed and restarted."

"Upon the new start, that man who remembered still retained his memory. The man was no longer affected by the cleansing. It was at this moment that the man swore he would break free from the cage he was imprisoned in. Obviously, I'm sure you could guess who this man was."

The original incarnation looked at Ren waiting for him to answer. Seeing the look the original incarnation was giving him Ren sighed before responding.

"The man who broke free from his shackles was you. So what happened next?"

"The next part can only be told, once you proved yourself."
