“We’ve always had each other, haven’t we, brother? Together we crawled from the gutter—and we both know where our path now leads...”

Bound by blood and a shared past of pain, two brothers walk very different paths: one is a ruthless Yakuza enforcer, the other a high-ranking civil servant. But beneath their contrasting lives lies a common purpose—revenge.

Years ago, a powerful corporation destroyed their family. Now, after years of meticulous planning, the brothers are ready to strike back. But just as their long-awaited vengeance nears, their younger step-sister begins to uncover the truth about her tragic past.

As she digs deeper, the brothers must confront a devastating question: will their sworn loyalty to each other and their cause survive the innocence of the one person they vowed to protect?

This gripping suspense weaves together crime, politics, and family loyalty in a high-stakes game of deception and destiny.
