Echo

Height: 164 cm (5'5")

Vincent's personal servant. She is somewhat emotionless, like a puppet, and treats Vincent's word as law. She fights with blades that come out of her long sleeves. It may seem that Vincent treasures her, but he actually does not care that much.

In Chapter 23, he goes as far as to poison her to prove that the antidote for the poison that he poisoned Shalon with works. Echo is shown to have her own mind when she saves the bottle of antidote that Vincent almost drops off the veranda, because she remember what Oz said the first time they meet. In Chapter 33 she admits that she finds Vincent annoying. She seems to developed feelings for Oz after both of them go to the festival together and Oz shows her what it is like to have fun, he also gives her a hair ornament which he was suppose to give to the girl he like, although he didn't know that.

In recent chapters she's known to have another personality called Noise, who is actually Zwei. Noise loves Vincent deeply and, according to herself, is the original personality inside Echo's body. She (Zwei) controls a chain called Duldum that can control other people or immobilize them using strings. Zwei used her chain to immobilize Gilbert, and also used it within Echo to capture Shalon.

With Zwei in possession of the body, she rejoins the Baskerville group and goes to Sabrie along with Lotti, where she meets Elliot and Reo. She immobilizes Reo using her chain, Duldum, but is only able to control his body, not his mind. Meanwhile Lotti stops Elliot.
