The protagonist does not fight, has no access to telecommunications, and specializes in "economic warfare." He changed the battlefield of the anti-war espionage war from the rumbling of artillery to the rustling of abacus and the ticking of telegraphs. By manipulating material futures, counterfeiting the enemy's currency, using intelligence gaps to carry out financial sniping, and destroying the enemy's inflation system, he made every inch of land won by the Japanese army on the battlefield an economic burden. This is a story about a "war economist" who sees through the nature of war and uses the flow of wealth to determine victory or defeat.
