Echidna

This page is about the Witch of Greed Echidna, for the Artificial Spirit, see Echidna (Artificial Spirit).

Echidna (エキドナ) was the Witch of Greed and one of the Witches of Sin. Mentioned throughout the series, particularly for her connection to Roswaal and Beatrice, she formally debuted in Arc 4 as a major supporting character and later secondary antagonist.

Throughout arc 4, her soul served as the overseer of the trials to remove the magic barrier surrounding Sanctuary. Learning of Return By Death, she attempted to get close with Subaru, but he cut her off after discovering her motives. At the end of the arc, she achieved complete rebirth by transferring her soul into a clone.

Appearance
Echidna has been described with two words - white and black, which express her extraordinarily stark beauty. She has long white hair that's reaching all the way down her back, and barely exposed white, porcelain-like skin. Most of the time she wears a pitch-black dress which is more similar to a dress someone would wear to a funeral, than casual attire, and a black butterfly hairpin (jade green in the anime). She has deep black eyes that shine with inhuman intelligence. Despite her extraordinarily beautiful appearance, Echidna injects overwhelming fear into everyone who is "lucky" enough to meet her, to the point people start vomiting in her presence, although it's worth mentioning Subaru somehow did not receive that side effect, he did however note that she was just as dangerous as the White Whale and the Sin Archbishop of Sloth if not even more. She is often seen smiling and acting very nonchalantly, until the topic shifts to something she's genuinely interested in. Due to her beautiful appearance, she often gives off a maidenly impression.

Personality
Echidna's curiosity toward the unknown and her thirst for knowledge are the two things that define her behavior. She refers to it as love, and currently directs those feelings toward Subaru's Return by Death, which she is interested to the point that she longs to become his advisor to record the many possibilities created from his ability.

Described as being black hearted, she cannot understand the feelings of others, and can be seen as a sociopath by normal standards. If it is to get a hold of more knowledge, she has no problems with employing sophistry, lying, and deceiving others. However, she interacts with ill will only toward three people in the world: Satella, Emilia, and one other person.

History
A long time ago, Echidna worried about everything, thinking of them as children that needed to be protected. She thought it was easy to control a world where things broke apart with the swing of a hand, however she decided to put her efforts into protecting things instead. Despite this, no matter what she tried, she was unable to do anything by herself, making her experience how powerless she was. Although she despaired, she didn't give up, knowing that she could reach her goal if she had more people with common interests. From that point on, she kept persevering, no matter how much she lost or was hurt, all to reach her goal.

Over 400 years ago, she served as a tutor for young Roswaal after saving him. In the following years, she created three Artificial spirits and started researching means of immortality by transferring her soul into a body which belonged to someone else. Throughout the years, she gathered humans and demi-humans alike, in order to create a perfect "sanctuary" which would be able to support the barrier. When Roswaal was 16 years old, he faced off against Hector and after being defeated and nearly killed, Echidna saved his life and engaged Melancholy. After Ryuzu Meyer, the Apostle of Greed, sacrificed herself in order to bypass the requirements and instantly activate the barrier, she successfully fended Hector off and saved the lives of everyone in the Sanctuary.

According to Echidna, royals of every country came to visit Echidna to borrow her wisdom at some point in the past when she was alive.
