Monoko

{{Monoko}} is a young monochrome grade school girl who has black hair tied into twintails and wears a white dress shirt with a gray skirt and white socks. She has a look of distress on her face, and she looks a bit worse for wear in that she has various scuffs and scratches on her body. When introduced to the Stoplight effect, she becomes a much more horrid sort of creature. Her pupils go white, her eyes and mouth begin to leak nasty fluids, she goes tense and her veins pop out, and a large gaping wound appears in her stomach. But most strikingly, she gains extra arms. One on the top of her head, two in the form of her ponytails, and two more, one coming from the middle of her left arm, and the other just below the right arm.

{{Monoko}} is a very slow and unintelligent individual. Despite her grotesque apperance, she acts like a little child. She's very much dependant on her bigger sister, and becomes nearly petrified with fear when Monoe goes missing. She also isn't particularly brave, and deals with stressful situations by breaking down and refusing to go on further.
