"Mediana, known as The Dangerous Doctor, is a brilliant physician and toxicologist who was ostracized by the medical community for her unorthodox studies. Draped in a nun-like habit with a large golden medical emblem, she carries a massive syringe capable of injecting potent medicines—or deadly poisons. She is driven by an unwavering commitment to preserving life, which ironically prevents her from testing her toxicology on humans. Instead, she uses demons as her primary test subjects, viewing their existence as a gift to her macabre research."
