上杉 勝子

Katsuko is a samurai of the Uesugi House, profficient in battling with a JAPANese Katana.

She is in constant competition with Torako, rivalry that goes both ways. Their relationship is pretty bad, being constantly fighting and arguing, but they still trust in each other in the battlefield, and they both share great admiration for Uesugi Kenshin.
