Kogoro received a call from Hotta Gaito, a spirit detective who is going to summon the spirit of Haneda Koji. Kogoro and Conan met Kokuri Senpei, the Toto TV director at the hotel lobby and discovered Gaito dead on his bed. Kogoro saw a figure flew to the nearest balcony and decided to check if there were casualties in the next room and found out that Masumi Sera is the one living next door.
