Amazing isn't it? A guy with massive fortune fear that his 5 children would repeat the family massacre he witnessed before. So he had his 5 children to be raised outside to prevent that only for all his children (except 1) to be killed off because of his fortune. And now he's on deathbed waiting for his final breath but all his children has predeceased him. And to add his massive fortune has completely gone, disappear without a trace except for a company worth minus 130 billion yen bankrupt. Just like the wise says, "fortune that are inherited never last". And to boot the killer is a fucking idiot who somehow didn't realize there's no way for the owner of company with 130 billion yen of bad debt would still have money for anything. Did he not watch TV, or looking at the company stock price and profit report. What makes him think there are any fortune to be inherited anyway? The killer committed 4 first degree murder for NOTHING. NOTHING.
