Ludwig is a handsome young man with blond hair (silver hair in the novel) that has bangs hanging on the right side and red eyes, traits that were passed down to Cosette in both the novel and manhwa.
Ludwig was once married to Rowena Weinberg where she tells him about naming their future child (depending on the gender), but Simon Edinburgh manipulates Ludwig into divorcing and kicking Rowena out of the Parvis Family after she fails to get pregnant.
After Rowena was kicked out, Ludwig later marries Simon's daughter, which results in the birth of Keira Parvis and Zekehart Parvis. As soon as Keira and Zekehart were born, Ludwig was unaware that Rowena was pregnant with a daughter who was possessed by a demon after Rowena gave up her soul.
- The name Ludwig means "famous battle", composed of the elements hlud "famous" and wig "war, battle".
- Like Cosette Weinberg, Ludwig's hair color differed in both the manhwa and the novel:
- He has blond hair in the manhwa.
- He has silver hair in the novel.
