Takeda No Kin, Mori No Gin

[Machine Translation] Akechi Mitsuhide was summoned by Oda Nobunaga, who had arrived in Kyoto, and given a mission. Nobunaga, a follower of numbers, needed to understand the financial strength of the rival feudal lords. In particular, it was essential to identify the Yunoku gold mine and Iwami silver mine, which were the source of funds for Takeda and Mori. To do so, however, he would have to infiltrate into the heart of the enemy's territory and check the ledgers that showed the amount of gold and silver produced. It would be a dangerous journey with no guarantee of life if they were discovered. Mitsuhide, accompanied by his ally Shinkuro and his foolish son, set out for Koshu in secret. The three arrive at Tago no Ura on Suruga Bay, where they meet an eccentric man who calls himself Tsuchiya Jubei Nagayasu. The true value of gold and silver is questioned.
