Jolyne also has a vindictive side and repays tenfold any wrong committed against her, notably indirectly cutting Romeo's tongue for betraying her and forcing her crooked attorney to crash his car. However, she readily uses lethal force against her archenemy Enrico Pucci, as he was the one enemy she explicitly said she would kill. Jolyne usually doesn't seek to kill and even said that she didn't want Ermes to become a murderer. Jolyne is particularly violent in her fights she's used the cutting ability of her string to gruesomely wound her opponents, severing ears and nails, for instance. to violently confront an inmate who cut in the queue for buying their lunch. She also advocates aggressively asserting herself, especially in prison, and once told F.F. A former delinquent living in a maximum-security prison, Jolyne had to toughen up and can be especially rude, frequently taunting her enemies.

She mainly wears a white linen peacoat with an elaborate flower motif with a matching scarf. In the one-shot, Jolyne makes an appearance in many different outfits.
