Case Closed - Season 1 - Eps 640: The Memory Trip of the Eight Sketches (Okayama)
Kogoro, Ran, and Conan are invited to Okayama to review the food served there. They then meet an amnesiac woman and decide to assist her in regaining her memories. The woman sketches out pictures which gives them clues on locations she visited. The woman recognizes the sound of a suikinkutsu from a cellphone; the group deduces she visited the Salt Palace. There, she discovers her name to be Mayuko Kichise from her friend, Kanae Nonomiya. Nonomiya reveals Kichise is an important witness who can prove her brother did not rob a jewelry store and prompts her to regain her memories. Nonomiya tells them the location of Kichise's home where they find it had been searched and pictures of Kichise and her boyfriend were ripped. Later at a restaurant, Kichise receives a note demanding her to be alone if she wants her memories. She separates from the group and is approached by a masked stranger.
