Uesugi Katsuko

Katsuko is a busho in the Uesugi family.

She is in constant competition with Torako.

After defeating the Uesugi family, Rance picks her and Torako out of a lineup for H.

However, she even treated this as a competition and felt superior to Torako because Rance chose her first over her rival. (Furthermore Rance commented she was prettier than Torako. However whether Rance genuinely thought so or was it a spur-of-the-moment remark because he was having H with her at that time is unknown.)

In Rance Quest she, along with Torako, follows Kenshin outside of JAPAN.
