Personalities (I say this because they share the same body) :
Echo Baskerville: Echo is an emotionless, fifteen year old girl who believes that she is not allowed to have fun unless her master tells her to, and if she does, she fears that she will be punished severely. She fights with blades that come out of her long sleeves and she enjoys recording everything she witnesses for there is so much see hasn't seen and wants to cherish those memories forever. Echo is just an Echo of Noise.
Noise/Zwei/Duldee Baskerville: Noise has a loud, more playful personality than Echo and uses others freely to her own will. She believes the world exists just for her and sees Echo as a useless child who is just taking up space in their body. Noise uses Duldum (her chain) to tie people up with stings and turn them into her "puppets", or what most people would call "possessing" people. Only one person has ever broken these invisible strings. Noise is a Noise of Echo.
Bio/History: One day, after Echo decided to have fun with someone other than her master, she was beaten to the point to which she couldn't move. To be punished even further, her master threw her into the closet to see how much "fun" she could have without him. As soon as Echo entered the closet, she had already broken it's rules, believing that if she had fun, she would be punished again. In order to survive, Noise, her other personality, now comes out for half of the day, using Echo's body, as compared to before when the turns were random and could sometimes go on for weeks, to teach the other children why they all must have as much fun as possible. Noise is the strict rule enforcer of the closet and if the children who haven't already become nightmares, she turns them into her personal puppets who are made to have "fun" at all times. No matter how much the other children may cry out in pain, she will continue smiling, even if her other half, Echo, is crying. They are two opposites despite the fact that they share the same body.
Appearance (this mainly shows the slight differences they have when using Echo's body, don't worry, they have the same hair color, I think the person screwed up on the hair color when doing the second one since it is a fan coloring and all) :
Echo Baskerville:

Noise/Zwei/Duldee Baskerville:

Echo watched as they feasted on the gorgon snakes and quickly recorded every detail of it in her journal.
"Good job." Her voice was monotone and no emotion besides it whatsoever, but they knew very well that she was complimenting them.
"I bet Hina and Sayu would have been very good hunters in the other world." Once again, a monotone vibe with no emotion. Echo continued writing in her journal, making sure she got down every detail of what just happened.

(( (how to tell who's talking)
Echo= black
Noise= red ))

Echo looked around for the person who was supposedly "hiding" themselves. She couldn't see anyone. Did they mean her? Did she really blend in that she went unnoticed that whole time? She continued sitting on her little rock and writing down everything there was to write. She still couldn't see who they were talking about.
"Don't worry. Echo will make sure no one spies on Hina and Sayu. Echo is a good girl." Again, monotone and no emotion, but even so, she had still gotten her point across that no one (that she knew of) was there.
