Calaveras was very similar to Prisma in the first anime: very arrogant and haughty, and very contemptuous of humanity. Unlike Petz, however, Calaveras was not very gung-ho about her mission, and her laidback attitude resulted in many fights with Petz, whom she always ended up being paired with on missions whether she liked it or not. Calaveras loved to tease all of her sisters, which led to arguing between Koan and Petz. Like Petz, she seemed to have some affection for Berdie and had normal conversations with her. She was also more interested in men than Petz, who claimed to dislike them.
