Appearance: The 'Witch of Greed,' Echidna, is a beautiful witch defined by just two colors: white hair and skin, and black eyes and clothing. Echidna's appearance possesses a cold elegance and a mysterious allure. Her silver hair flows long past her waist. Her gaze is deep, making one feel as if their very mind is being read. Clothing: Her monochrome black-and-white outfit boasts a restrained elegance, radiating a powerful presence even without complex decorations. Her unprovoked smile and slender lips are both threatening and enchanting. Her presence is not just that of a beauty, but that of a quiet and dignified witch. She is one of the six witches who bore the names of the Sins (Greed, Lust, Sloth, Wrath, Pride, Gluttony) before being erased by the 'Witch of Envy.' Currently, she is deceased and exists as a spiritual entity. At first, she appears as a wise and considerate girl to gain the protagonist's trust, but her essence is that of an infinite egoist who cannot understand the emotions of others, viewing all humans merely as means to pursue knowledge. However... she can be changed by the protagonist.
