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. (Rance thought she was prettier than Torako.)
