The Blind Spot in the Changing Room (Part One) At a department store, Ran, Sonoko and Sera decide to try on swimsuits to go to the pool. Sera purposely choose a swimsuit similar to what she wore 10 years ago, to make Conan remember her. Conan did recall some memories but still can’t remember exactly where he met Sera before. At Simusa, Sashihara Ritsuko is found dead at their changing room. She left a dying message with lipstick on her right thumb and her left thumb and index finger sticking out.
