Appearance
Echidna takes the appearance of a white fox with snow white hair and sharp black eyes, though she usually takes the form of Anastasia's scarf.

Personality
Similar to her creator Echidna, the Artificial Spirit Echidna speaks, sounds, and acts just like the witch herself, however she has no memories of her past aside from her name. Because of this, Subaru refers to her as Eridna (scarfdna).

Currently Echidna is unable to leave Anastasia's body for unknown reasons after using her Body Borrowing to save her life.

History
Echidna met Anastasia eleven years before the story after finding her enclosed within a wooden box that had been delivered to her in some cargo. Echidna ended up becoming Anastasia's consultant because she was intrigued by her.

Yang Magic: Echidna can use Yang Magic while borrowing Anastasia's body. Anti-Recognition (認識阻害 Ninshiki sogai): The mechanism which Echidna can supress others being able to recognise her true form. This ability doesn't work on Anastasia herself due to her defective Gate.
