Nemesis is a foreigner from the mythical world of Tetra-Heaven who serves as the partner of Veronica Ananko, the chief of the Another Logic Counter Agency (ALCA) in Naien. She is titled the Goddess of Wrath and Punishment, yet her demeanor contradicts that name. She is perpetually smiling and rarely becomes serious, even in the midst of a crisis. Despite a youthful, childlike appearance, she possesses a sharp tongue and a perceptive nature, often pointing out the flaws in others with snide remarks. She is also highly knowledgeable and well-read, belying her small stature. Nemesis has a notable fondness for zombie movies and is drawn to grotesque or macabre things. In the story, she acts as a supporting figure, assisting Veronica in overseeing the training and education of logicalists at ALCA, such as hosting remedial classes. Her relationship with Veronica is one of close partnership, and she appears alongside Veronica in various administrative and observational roles. While her specific combat abilities are not detailed in the available information, as a foreigner goddess she is inherently powerful and participates in the logic-based trance system that defines the series. Her character shows little overt development, remaining consistently cynical and amused throughout.
