About me: Echo and Faith are sisters and deadly nurses. They are related to the Twins of Prevention and it shows in the way they tell their targets to not misbehave while holding them down and injecting them with an untraceable toxin which will kill the targets in a matter of seconds. The Grim Reaper himself follows the sisters and reaps the spirits of the ones they kill. Echo and Faith each have a special doll that they carry in their medical bags. Despite their deadly intentions toward targets, the sisters are actually very friendly and love helping people.
