I heard a story of a girl that switches schools often. Sometimes people disappear after she arrives. She's said to be from nowhere. Strange things have happened after she arrived. For example, a man had a baby. Another example, writing on the bathroom walls became true. What is the name of this mysterious girl? Who is she?
