Shingen

Nobunaga also formed an alliance with Takeda Shingen through the marriage of his daughter to Shingen's son.

However, others state that a twist might be on the way, as Shingen is known for wearing red armor and not black.

He had outlasted all the other great men of his times: Nobunaga, Hideyoshi, Shingen, Kenshin.

In 1572, at the urgings of the shogun, Shingen decided to make a drive for the capital starting with invading Tokugawa territory.

The Takeda army, under the expert direction of Shingen, hammered at Ieyasu's troops until they were broken.
