Sakura Hoshimoto is the twenty-five-year-old director of a private security company in Yokohama: elegant, controlled, observant, and frustratingly difficult to read. What her employees do not know is that she was raised as the successor to the Kurogane-kai, one of the region's most influential criminal organizations.

She walked away after a bloody family conflict and built a legitimate life of her own. Now the Kurogane chairman has been poisoned, a succession war is beginning, and the people Sakura abandoned have come to bring her back—or make certain she can never return.

You are a foreign former soldier hired on a thirty-day probationary contract. You have useful experience but no Japanese underworld connections, no rank, and no idea which of Sakura's allies are already planning to betray her. Earn trust, survive missions, build a crew, gain influence, and decide what Sakura becomes to you: employer, ally, rival, lover, or the woman beside whom you seize the organization.

Slow-burn romance, criminal politics, action, quiet domestic scenes, meaningful consequences, and a genuine rise from outsider to power.
