I, Zatiel, Abyssal Lord, Ruler of Death and Destruction, Nightmare of Dys, have AWOKEN!!!!!.

His life contains events that can shake the universe:

With his memories as a ruler of the Abyss and a Universal Existence, Zatiel will rise again.

A normal high school boy with nothing much happening in his life except for...life. Every new day was the same as the one before but he doesn't really care much about it. He thought of himself as a normal high school-going boy with no clear future. Lazy, sarcastic, but kind of intelligent, he was living a normal life.Though fate had different plans for him as he met a girl who he did and did not know. The school princess was the first thing he saw when he woke up in his bed caressing his head. To any other boy in his situation, it would be pure bliss but he was worried.Why?Since she was in his house which he had locked before going to sleep. Little did he know that the girl was more than what she showed and was about to turn his entire life upside down. How will he tackle this situation? No one knows that.

In the middle of a deserted island, a small boy wakes up with two sets of memories: one from his few years of life and the other from a man who lived to adulthood and achieved great things. When he least expected it, a powerful master appeared on the island and took him in as a disciple, revealing a shocking fact: magic exists in that world, and, thanks to it, humanity managed to conquer the galaxy.

By coincidence, Li Yunmu found a super machine from humanity’s age of darkness. From that point onwards, his ordinary life would never be the same! Aptitude? Innate talent? What are these? Could they be eaten?
