Yukimura Sanada is the Lord of Ueda Castle.

His stubble and casual dress makes him seem like he's not a feudal lord, and Saizo often calls him 'old man'.

He is an eccentric man, and though he seems sloppy at first glance, he is very broad minded and smart. Shown when he used Saizo and Isanami as bait to allow their enemies to reveal themselves.
