Echidna and Subaru

Intro Appearance Echidna's barely-exposed skin was porcelain-like and pure white, so white that it seemed any semblance of color had been completely bleached from her existence. Her black eyes shone with intellect and were the only part of the woman that looked alive. Her long straight hair reached down to her back and was as white as her skin, and it also had a black butterfly hairpin (jade green in the anime). Anyone who saw her would be instantly captivated by her striking beauty, although the sight of her would also inject overwhelming fear into a person's soul. Although her spirit in the Castle of Dreams was in her late teens, Echidna's slender body appeared as though it was in its mid-twenties.Personality Echidna's curiosity toward the unknown and thirst for knowledge were the two things that defined her behavior. She referred to it as love and directed those feelings toward Subaru's Return by Death, which she was interested to the point that she longed to become his advisor to record the many possibilities created with Subaru’s Authority.
