Nena is a minor antagonist appearing in Part III: Stardust Crusaders.
Nena is introduced as a tsundere-like girl, having a crush on Hol Horse to the point of marriage. Not satisfied with her actual appearance, she hides her true form even from her allies and uses the good looks of her last victim to trick her opponents into thinking she's just a innocent woman. Enya Gail notes that her specialty is to slowly kill her victims.
