Ryuk’s life in the forsaken Grade E city was bleak, but it truly shattered when a Knull raid took his last family and left him for dead. 

On the brink of despair: 

[System Activation Complete.]

[Congratulations, Host has awakened the Draconic Pets Evolution System!]

[Welcome host, to the path of domination.]

Thrust into Endearth, a shattered mirror of Earth teeming with mythical creatures—vampires, werewolves, cosmic gods—and the unstoppable Knulls, Ryuk sets out on a journey of relentless growth, vengeance, and discovery. But power comes with a price, and the dual nature of his gift could either save humanity or destroy everything.

This is a story of evolution, redemption, and defiance. Join Ryuk as he rises from nothing, building unshakable bonds with allies and carving his path in a world where strength is the only currency.

A/N

1. Hardworking protagonist. Ryuk doesn’t rely solely on his system; he earns his power.


2. Overpowered potential. Growth takes effort, but Ryuk will become a force to be reckoned with.


3. No hiding strength. He plays smart, but when it’s time to fight, Ryuk doesn’t hold back.


4. Dark and morally complex. Ryuk is vengeful and will cross any line to protect what matters.

5. No harem. Relationships are meaningful, not shallow.

6. Lastly, if this novel stirs even the faintest flicker of interest in your soul, pour your undying devotion into it! Haha, just kidding… or am I? But seriously, please shower this story with power stones and drop some reviews. Your support fuels Ryuk’s journey (and keeps me caffeinated while writing). Thank you!

"It is the manifestation of your willpower," the blue-scaled Ryuk answered Ryuk's question, and Ryuk couldn't help but raise his hands to feel the tattoo on his eyes.

"The cultivation of Aetheris must be treated just like the cultivation of Apex Energy."

"But I suppose you don't have any manual to cultivate it, as that world of yours will have no idea it even exists."

"I'm afraid you will have no choice but to find a way to increase it yourself, or the basic level will be all you ever manage to reach, for as long as you stay in that low-level world."

"All I can say is that your Aetheris is the manifest energy of your willpower. Train your willpower, and your Aetheris increases."

"Right now, you're at the most basic level of it, so be aware of your abilities."

"Atheris gives the illusion of ultimate power, but it's an illusion."
