Tập 1: Furuta Sasuke thương lượng cho ấm trà Hiragumo trong khi Nobunaga thử thách lòng trung thành của anh ta bằng một chiến hạm.

1

Furuta Sasuke, a 34-year-old vassal of Oda Nobunaga, is sent on a diplomatic mission to Shigisan Castle to negotiate with Matsunaga Hisahide, a general who betrayed Nobunaga and allied with the Mori Clan and Ikko-ikki. Nobunaga instructs Sasuke to offer Hisahide a pardon for the betrayal in exchange for the Hiragumo teakettle, a highly-prized and artistic piece. October 1577 is the date of the siege. On the day of the negotiations, Hisahide refuses to surrender, instead filling the teakettle with gunpowder and strapping it to his chest. After the kettle explodes, Sasuke manages to preserve the top of it. In 1578, the first of Nobunaga's immense sea vessels are completed, known as the Great Atakabune, and it is set on display in the harbor. A merchant disparages Nobunaga for spending so much on the fleet, and Nobunaga, overhearing, kills him, not for the disparagement, but for not sticking to his opinion. The lord then, as a test, asks Sasuke whether the Hiragumo teakettle or the Great Atakabune military vessel is superior. (Source: Wikipedia)
