On October 5, 1994, a seventeen year old high school student named Yuri meets a polite yet mysterious elderly gentleman at the crosswalk. Although puzzled by his questions, she answers them honestly to the best of her ability. As Yuri walks across the street, she hears the man mutter the word "Emit" to her. Yuri thinks nothing of the conversation until an oddly familiar yet attractive young man approaches her a month later on the street.
