Echidna (エキドナ) is an Artificial Spirit in the form of a White Fox, usually taking the form of Anastasia Hoshin's scarf.


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.


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.


Echidna met Anastasia eleven years before the story and became her consultant because she was intrigued by her.


Body Borrowing: In emergencies, Echidna can overwrite her existence onto Anastasia's od, making her able to temporarily borrow her body, and by doing so, she can use the mana inside of Anastasia's body to use magic.

Yang Magic: Echidna can use Yang Magic while borrowing Anastasia's body.

  • Jiwald (ジワルド): Jiwald is a Yang Element magic that allows Echidna to fire heat rays from her fingers.


  • Echidna's name refers to 42355 Typhon I Echidna, 42355 Typhon's moon and a companion to a binary asteroid. In Greek mythology, Echidna is a monster who was the mate of Typhon.
