Rapunzel is the older sister of Girom. Their father died early of an illness, after which their mother became deranged and physically abused the siblings on a daily basis. Gradually driven to their limits, one day Rapunzel and her brother finally broke down and chopped their mother to death, then ran away. The scar of this matricide survives into her adulthood: Rapunzel grows up to be bloodthirsty, arrogant and riotous (to the irritation and exasperation of many Knights), and appears to share with her brother Girom (notably the only one she holds dear and is gentle with) a love for killing women. Despite being quite far from most visions of beauty herself, Rapunzel is shown to be helplessly narcissistic and looks down on everyone, men or women, as obnoxiously ugly.

She also enjoys talking about how she'll have orgasms in the middle of fights.
