Sister Street Fighter: Hanging by a Thread

The story

Koryu heads to Yokohama looking for Birei, a woman kidnapped by diamond smugglers who hide their stones by surgically implanting them into Chinese prostitutes. Etsuko Shihomi is Koryu, following the trail through the city’s gangsters and black-market operators as the case turns back on her own family. Her older sister, a jewelry designer, is secretly involved with the ring and unhappily tied to its operations. What begins as a rescue mission winds through martial-arts fights, criminal schemes, and a smuggling operation that reaches from the underworld into Koryu’s closest relationships.
