In Black Lagoon, Eda is a member of the "Rip-Off Church" or as it's more commonly known, the "Church of Violence." She and her superior, Sister Yolanda, sell guns to the various factions of Roanapur, and the Lagoon Company are a frequent customer. Eda and Revy have an adversarial kind of friendship with each other, and Eda constantly teases Revy about Rock, which never fails to annoy Revy.
