上杉 虎子

Torako is a mage of the Uesugi House proficient in the Yin-Yang arts. She has an iconic accessory in her head that resembles bear ears. She is in constant competition with Katsuko, 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.
