Shinichi enters the case's keyword, "ta-n-jo-u-bi" (birthday), releasing Ran from the infra-red ray sensors. He rushes to Ran, feeling confused after calling her two times, and suddenly realizes something. Standing up, Shinichi states that now he understands why they are trapped in the room, and that Ran is the culprit behind everything.
