Eda is so fascinating as a character. When we're first introduced to her, she is presented as Sister Eda, the gunslinging nun who is something of a long-time rival to Revy and her opposite. Where Revy has no standards of morality, Eda judges her as being too impure to enter the church proper. Where Revy is hot-headed and quick to anger, Eda is cool and keeps a constant pokerface. She's also presented as the right hand of Yolanda, in the same position Revy is to Rock and Dutch, and Boris is to Balalaika.
Then Bloodsport Fairy Tale happens. We meet Eda, a sleazy and moneygrubbing mercenary. She's no longer in her nun's habit and instead in more chic and revealing clothing. She's actively flirtatious with Rock, teases and banters with Revy, and feels very different to when Eda was first introduced, though it's a believable enough departure. You think "Ah, this is the real Eda! When she's on the clock at the church, she's more reserved, but when she's off and out of the habit, she's much more wild and fun! Cool!"
Her appearance is also a perfect parallel with Revy's: She wears a bright pink graphic top with spaghetti straps, a light blue denim skirt and a white belt, high heels and a cross tattoo on her right bicep. This contrasts with Revy's more practical black tank top, denim shorts, green double grommet belt, combat boots and tā-moko inspired sleeve tattoo. Not only that, Revy wears a ponytail while Eda has her hair down, the back part tucked away by a hair band. The only bit of her outfit that does not have a counterpart with Revy's is her Terezi ass looking glasses.
However! That's not the real Eda either! In Roberta's Blood Trail, we meet Edith Blackwater, a CIA agent from North Virginia who graduated from Harvard University. She dresses in a very formal looking suit, wears her hair in a bun and has a pair of prescription glasses, a stark contrast to every other time we've seen her. And she's still the opposite of Revy somehow! Revy is an escaped felon on the run from the US government, Eda has the backing of it and all her actions are sanctioned by the CIA, Revy never even finished middle school, Eda attended an Ivy League college, etc.
I just think it's interesting that she's under several layers of false identity that slowly gets peeled back over the course of the series and has multiple introductions of sorts. And I have a feeling that "CIA agent" isn't all that she is, and has yet another layer of identity under that. I should really read the light novels and her spin off series...
