In this chapter, we learn that Yurika is a voice actress who has just returned from a diving trip with her fiance, Hiroyuki Sanada. The two of them are staying at a hotel in a seaside resort town in northeastern Japan. Yurika tells Hiroyuki and the other divers that she's back from her trip with Hiroyuki. She's upset that Hiroyuki seems to have given up on her, but he assures her that he'll be back soon.
