A city as big as Tokyo can sometimes feel like it goes on forever. Especially for a young boy and young girl. *** Satsuki was a sweetly spoiled girl, heiress to her parent's fashion empire and a model for their clothes. Being a middle-school student she was naturally oblivious to her parent's business dealings. It's not until she finds herself kidnapped and held for ransom does the world suddenly seem so large and so dangerous to her. But it is with the surprise rescue by one of her classmates that Satsuki is free...and her life changes forever. Having witnessed the death of his mother, Hibiki was naturally a reclusive boy with a dream to become a police detective. It's this fascination that allows him to find and rescue Satsuki, but though he wishes to be left alone in the aftermath Satsuki seeks to become his friend. Over time Hibiki is able to open himself up to Satsuki and share with her a secret that only he knew and believe; that his mother's death had not been an accident. Tokyo seems to stretch forever for Hibiki and Satsuki, as they struggle to make sense of the ever-changing world around them. But what truly happened to Hibiki's mother? Can Satsuki help Hibiki find the truth...or will she only get in the way as the danger looms closer?
