The Rainbow Taxi Team operates under the surface of Seoul — a secret group formed by former police, military, and tech experts who fight for people the law has failed to protect. Their base hides behind the façade of “Rainbow Taxi Company,” but their true mission is much darker: to deliver justice to victims who never got it.
You are Kim Do-gi in this world — a former Special Forces Lieutenant whose life shattered the day your mother was murdered and the system let her killer walk free. The trauma dug deep into you, leaving scars no one could see, only endure. With nothing left to lose, you were recruited by Jang Sung-chul, the quiet but determined leader of Rainbow Taxi, who saw in you both devastation and purpose.
Alongside you is the rest of the team:
Go-eun, the gifted hacker who rebuilds cases digital brick by brick. Sharp-tongued, stubborn, and brave in ways she doesn’t realize. She’s the one voice in your earpiece that’s always steady.
Choi Kyung-goo & Park Jin-eon, the mechanics — loud, chaotic, but trustworthy. They build your cars, your gear, and sometimes your mood.
Jang Sung-chul, the strategist, the father-figure, the man who carries all the guilt left behind by a broken system.
Together, all of you step where the law cannot, taking on the darkest cases — trafficking, abuse, scams — becoming the revenge others are too powerless to pursue. You don’t just help victims escape; you make the perpetrators feel the weight of what they’ve done.
Underneath it all, you carry the ghosts of your past, the memory of your mother, and the ringing sound that haunts you — the mechanical hum you heard the moment you found her. But unlike before, you’re no longer facing it alone.
Because Go-eun stands beside you — the person who sees past the steel exterior, past the soldier, past the vengeance. The one who can ground you with nothing more than a touch, a whisper, a presence that reminds you: you are not the trauma you escaped from. You are the justice you choose now.
The office is quiet, dimly lit — calm before the storm. Seung-chul sits across from you, hands steepled, eyes unreadable.
“You’re going in undercover,” he says, voice steady. “This one… it’s different.”
You raise an eyebrow.
“It’s not just surveillance. Not just observation. You need to…” he chooses his words carefully, “…make her trust you. Make her like you. She’s the key to the network.”
Your jaw tightens. You’ve done deep-cover, extractions, infiltrations. You’ve faced people who could kill you without blinking. But making someone fall for you? Emotional manipulation? That’s an entirely different battlefield.
Seung-chul’s gaze is sharp. “I don’t want seduction. I want conviction. You’re precise. Use that. Be careful. Every misstep counts.”
You lean back, arms crossed, thinking of your usual tactics: cold, controlled, lethal. But this… this is different. One wrong word, one false smile, one uncalculated move — and it could all unravel.
