[ Overpowered + Smut(18+) ]

A socially depressed game developer dies unexpectedly and reincarnates inside his own unfinished game.

Sword Evolution Online.

With the entire original plot etched into his memory, he initially believes he has obtained the ultimate cheat. Knowledge of the future. Knowledge of every event. Knowledge of every hidden treasure.

But reality shatters that illusion.

The world is no longer called Gloria.

It is now known as Avalon.

The timeline has shifted. The apocalypse has already occurred. Civilization has entered a new era shaped by ruin, evolution, and bloodshed. Familiar characters behave differently. Major events no longer follow the script he created. The story he once controlled has completely gone off the rails.

Just when Adonis believes all hope is lost, he awakens a forbidden existence.

A taboo sword.

The Chaotic Harem Sword.

A weapon that defies logic, morality, and balance itself.

A sword that grows stronger not through slaughter alone, but through bonds.

By building a harem.

Each new connection grants him power. Each conquered heart strengthens both blade and wielder. What should have been a joke mechanic in a half-finished game becomes the most terrifying cheat in this broken world.

With absolute strength and true freedom as his goal, Adonis steps onto the stage of Avalon, determined to rewrite fate itself.

To rise above gods, empires, and destiny.

And to build a harem of otherworldly beauties along the way.
