I would like apologize for not posting more often. Been busy of late. I am still rereading Varley's article. There is ton of rich information that needs to be answered. As for The Signore, my final answer is that the book, even though it is fiction, portrayed Nobunaga as a lonely man. One must remember that he put most of his energy to unite Japan. When you experienced a lot of backstabbing in your life, you tend not to trust people.
At the moment, I am writing a fiction novel on Nobunaga. It will take at least three months to finish the first draft. A word of advice to the current economic slump. Have plenty of cash, buy gold, and pay your debts off. As for the Okehazama book, the editing process is still going on. Little by little it will be done and published.
Tenka no tame!
