Reiko Fujikawa

Reiko was supposed to have been merely Tokuko's piano tutor. What her employers didn't know is that she was part of a plan to kidnap their daughter for a fortune in gold. She tricks Tokuko into trusting her, only to betray her later. Reiko is rescued from the lake by Neo and discovered by Bando, who takes her in on the condition that she helps him out in return.
