Okami Wa Nemuranai - Chapter 20.18

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again.

- Description from novelbuddy

Kyros Steele was the strongest warrior in the Omega Kingdom. But when the Great War of All began, this kingdom fell. Kyros was captured.

Destined to become a slave through necromancy, Kyros could only curse at his led bitter life.

But on his final moments, he meets an eccentric Old Man who claimed to be the God of Time.

Much like Kyros, this Old Man was fated for suffering and defeat. Because the God of Time could not be killed, the Great Gods conspired to curse him and make him human first. And so the God of Time escaped but was now human. Even if he used his powerful magic to send his consciousness back in time, he would still be defeated, for his soul was no longer a god but a man.

Helpless as his time-traveling rebirth would easily fail, the God of Time offers and asks for Kyros's help. He would send Kyros back along with his own consciousness back in time. This would hide the God of Time from his enemies and give Kyros the chance to fulfill his revenge.

Just when the two were about to time travel, a shocking mystery caused the God of Time to marvel in awe. Kyros was not a human but had the bloodline of the most accursed and dangerous race of all.

Kyros is the legendary Nephilim.

And so begins the Ascension of the Nephilim.
