Chello (New Bendy OC)

Name: Chello
Gender: Female 
Alignment: Neutral Good

Backstory: Chello was a sweet kind woman. Her voice would give some very good impressions from the others who worked at the studios. 
She was a gentle soul, until the day it happened. 
Chello realized something was wrong, so she walks outside one of the rooms, only to be attacked. 
She was screaming, and trying to break free, but no one heard her cries of desperation as she is dragged into the ink machine. 

30 years later...
Chello is now a walking demon who comes out through the floors of the animation studio to see everything has drastically changed, and it's falling apart. 
But she wasn't the only one here. 
There was another, who was sitting near one of the animation desks, and she befriended a woman who was in the same condition as her, only for her to revert back to normal. Seems like this woman has some of her morality taken away, and is fighting over control.
