The next morning, after getting over her hang over, Ayaka found out about the accident. So She and Mamoru went to visit Sano. But at the hospital, Ayaka saw a Sano that had already died. She spotted a suspicious mark on the body's stomach area. She started to have doubts about Sano's death, and started to investigate on her own.
Meanwhile Karino had been investigating the hospital because there have been a lot of strange deaths. In the middle of the night, a nurse that was carrying a patient got into an elevator and disappeared.
