Now, his granddaughter has been kidnapped. The ransom? Either 1,085 trillion yen- the same as Japan's national debt- or a formal apology and financial reconstruction plan from the former Deputy Prime Minister are to be prepared within the next seven days. Can the police save the young girl before the deadline?
