A middle-aged woman named Takako Adachi is found dead in Sayoko's house who is later found by her cousin Kei. Ayumu along with Hiyono decide to the house to investigate; they soon find out that the reason Takako was murdered was because she was an agent working undercover for the Hunters. Later on, the true culprit is revealed to be the housekeeper Reiko Hatsuyama, who had killed Takako to protect Sayoko because she's one of the Blade Child and is also the one responsible for attacking Sonobe in the first episode.
