Oskar Zelek, a 42-year-old NEET and unfulfilled economist, is fatally stabbed while trying to protect a girl… only to be given a second chance by fate.

He is reborn as a tiny hydra in a dangerous, chaotic world — one that is slowly approaching a catastrophe...

From a helpless hatchling, Oskar begins a brutal journey toward becoming one of the legendary Demon Lords.

Alongside Valeria, a cunning and proud vampire, he builds something impossible: a nation of monsters. Together, they unite forests, mountains, and islands under a single growing banner.

But the world does not remain still.

Deadly dungeons awaken. Ancient cataclysms spread. Rival gods, human empires, and ruthless guilds driven by greed and ambition all begin to move — each one ready to crush anything that threatens the balance.

And something far worse is coming from beyond the world itself.



What you can expect in this story:

This is a long-form fantasy story focused on kingdom building, survival, and character growth — from the very bottom to world-shaping power.

A strong emphasis is placed on both main characters’ pasts, and how those experiences shape their present decisions. Their struggles, mistakes, and personal growth are a core part of the story.

There is also a slow-burn romance developing in a harsh and unstable world, where survival often takes priority over emotions.

The story follows the rise of a kingdom from nothing into a major world power, set against the backdrop of an approaching catastrophe from another realm.

You will see many factions, battles, and characters throughout the story — each with their own goals, conflicts, and influence on the world.

This is a planned long series (~800 chapters), focused on gradual progression, world expansion, and long-term character development.

This series will no longer be updated on this platform.


All future chapters and ongoing updates will continue on Royal Road under the same title.


The existing chapters will remain here as an archive for current readers.
