"Hey, Ju Mi, you think you know your brother? You may be his twin sister, but you don't know a thing about him. That guy… he's the Viper No. Zero, the former leader of Shadow Vipers!"
The name Viper No. Zero was spoken in whispers, a legend wrapped in shadows. Always dressed in black, his face hidden behind a half-black, half-white mask, one side laughing, the other crying. No one knew who he was. He appeared from nowhere and vanished into nothing.
On the back of his black jacket, a single number burned like a warning, Zero painted in deep, bloody red. That's why they called him The Viper No. Zero.
He was the heart of Shadow Vipers, the gang that ruled the streets of Itaewon, not with chaos, but with order. No criminal could set foot in their territory. No predator could hunt while the Vipers watched. They weren't just delinquents. They were the ones who hunted the hunters.
The Predator of Predators.
But a year ago, Viper No. Zero disappeared without a trace. And with him, the Shadow Vipers faded into the past. Itaewon was left unguarded.
Now, a new gang has risen... Big Dragon. But they are nothing like the Shadow Vipers. Corrupt. Ruthless. Hungry for power.
The streets tremble once again.
And somewhere in the shadows… the Viper watches.
