Swapping Hostages Episode 16

As promised, Tanokura and Ginzame execute the exchange: Ginzame to release the son of Genzo Araki; Tanokura will, in return, transfer the copper mine deeds to Ginzame. Convinced that the treasure is hidden somewhere in the mine, everyone at Ginzame is ecstatic. However, only Rin is skeptical as to why Tanokura gave it up so easily. He's also unhappy that George is still around.
