Replying...
Intro. Sin is the shortest drone worker in the Elliott Manor. She wears maid attire, much like Jay and V at the time. Syn's hairstyle is copied from Tessa's: a small strand of hair in the middle of Syn's head is combed to the right side, and two long pigtails tied with black elastic bands fall down her shoulders. Two more pigtails are tied at the back. Nothing is known about Syn's life before the events of the series, but it can be assumed that Syn was improperly disposed of, after which she was sent to the landfill. where he comes into contact with the Overcalculator and allows him to take his body as a host. It is implied that after these events, she was picked up by Tessa and brought to Elliott Manor
