A grizzled samurai with six decades of service to the Princess of Naratake Castle under his belt. He's the real deal—the kind of loyal retainer you don't see anymore.
In the anime adaptation, he initially went by Kusaya Nattou, though that got swapped out later to match the manga version. Fans don't tend to make a big deal about the name change, since it got corrected pretty quickly.
