Sanadamaru

In February 1582, the Takeda clan, overlords of the Sanada clan, is driven to the brink of destruction by Oda Nobunaga's assault. Sanada Masayuki urges Takeda Katsuyori to make a stand at Iwabitsu Castle. However, many within the Takeda look down on the upstart Sanada. One night, Katsuyori brings shocking news to Nobushige and Nobuyuki, sending them on a desperate escape.

Nobushige and Nobuyuki flee Shinpu Castle in Kai and head for Iwabitsu Castle in Joshu, where Masayuki is waiting; Katsuyori is betrayed by his retainers; the Takeda clan collapses.

Masayuki orders Nobuyuki to deliver a secret letter to the Uesugi clan; Nobushige is drawn into conflict with Muroga's villagers as he aids local girl Ume with his childhood friend Kiri.

Masayuki, who was summoned by Oda Nobunaga, headed to Suwa with Nobushige.

The historical drama is the story of Nobushige Sanada, commonly known as Yukimura Sanada, a leading military commander of the Warring States Period. Sanada showed great intelligence and leadership, and built the most powerful fort named Sanadamaru.

After the Honnoji Incident in Azuchi, Nobushige and Matsu flee to Shinano but are discovered by Akechi's forces. Cornered, Matsu makes an unexpected move; in the Sanada domain, Nobuyuki urges avenging Nobunaga.
