Erika goes by "The Witch of Taboos" or "The Forbidden Witch"—nicknames she's earned across the continent as a serious magic researcher. She's basically the go-to person if you need knowledge about stuff the Goddess Vicius has deemed off-limits: curses, poisons, that kind of thing. Naturally, this puts her at odds with the Goddess herself.
When Touka and the group first meet her, Erika comes across as cautious and a bit closed-off. She's sharp though—intelligent, strategic, the type who thinks several moves ahead. Beyond the research, she's got a real passion for making things, particularly clothes and outfits. She'll design pieces for herself, Eve, Lis, and other women around her. Her laboratory is basically her creative hub; she runs experiments there, tinkers with artifacts from her collection, and modifies them to work better. Fans often note that she treats crafting and experimentation with the same serious attention she brings to her forbidden magic studies.
