(Underground World)
Beneath the polished streets and glittering towers lies an empire unseen - the underground.
Here, law holds no weight. Power is measured by blood spilled, oaths broken, and the symbols one dares to carry. Every gang is a kingdom, every leader a throne, and every name whispered with either respect... or terror.
Among them, none are feared more than the Black Feather Gang. Their mark is unmistakable: a black feather tied at the waist, earned only through blood. And above them all - the one no one dares name - the King of the Black Feather. His sign is a single red feather among the black, a symbol of command and death.
No one has ever truly seen him. For those who claim they did... never lived to tell the tale.
His fighting skills are said to be sharper than any blade; even a single touch from him can end a life. That is why the underground trembles at the mere mention of his existence.
And yet - for nearly two years, the Black Feather Gang vanished into silence. No moves. No killings. No feathers left behind. To the underworld, it was as though they had disappeared. Some believed it was peace. Others whispered it was a storm waiting to strike.
Now, rumors begin to spread again... the Black Feathers are returning to their true path.
Leo( main lead)
At twenty-seven, Leo stands at the throne of the underground - or so he believes. He came in like a storm: young, rich, arrogant, his empire built as much on glass towers as on blood-soaked alleys. To the world above, he's a billionaire with polished shoes, velvet suits, and the kind of arrogance that makes men bow just to avoid his gaze. To the underworld, he's the "new king" - ruthless, loud, and untouchable.
But there is one truth he does not know. His rise came during the two years of silence, when the most feared gang of all - the Black Feather - disappeared from sight. He believes himself superior, but the veterans of the underground whisper otherwise. They know the Black Feather is not gone, only watching. And if they return, Leo's throne may prove paper-thin.
Kai (main lead)
Twenty-four, quiet, and forgettable at first glance. He doesn't belong to the world of blood and steel - at least, that's what his face says. His beauty is gentle, refined like a classical painting: pale skin untouched by scars, soft lips, and hair that falls in messy dark waves across his brow. He looks like someone who has never touched violence, someone too fragile to even hold a blade.
Yet those who dare to meet his gaze never forget it. His eyes, a calm black-brown, hide storms too vast for words. They carry a sharpness that contradicts the innocence of his face - a confidence buried deep, as if he's hiding truths no one is meant to see. He smiles softly, speaks kindly, and walks as if the world is harmless... but there's something in him that unsettles even the bravest.
Because behind that gentle mask is a shadow no one can quite name.
Mark (23)
Leo's loyal secretary, silent and precise. He holds the underground's numbers, faces, and secrets in memory sharper than knives. With neat brown hair, pale skin, and warm hazel eyes behind thin glasses, he seems more professor than criminal.
But the stillness in his posture carries authority, and the calm in his face conceals a man no one dares to underestimate.
Nero (The Parrot)
A splash of grey feathers and eyes like polished obsidian. More than a pet, Nero is Leo's sentinel, repeating words no one else dares speak. In a world of liars and traitors, Nero alone speaks freely to his master - mocking, warning, and witnessing every truth the underground fears.
The Whisper of a King
In this world of shadows, loyalty is dead and power is everything.
Rumors spread like wildfire - that the silent King of the Black Feather has stirred once more.
No one has seen his face. No one knows his true intent.
But one truth echoes across the underground:
The day he returns... the world will bleed.
