While making bombs for Keigo, Minene remembers the time when she was captured by a detective named Masumi Nishijima while confronting Takao. Although they developed a rapport as they evaded and defeated the killer, Minene ended up knocking Nishijima out to escape. Aru sets up Yuki and Yuno on a date to a bridal fair for a mock wedding, where they meet Keigo's wife, Naoko Kurusu, while he investigates Yuno's house. When Yuki and Yuno return, they find Aru at the door of the room with the corpses. However, the wall is demolished and the corpses are buried in a deep hole in Yuno's garden. Even though this is Yuno's doing, she has no recollection of the event, nor of Yuki visiting her house before. Aru theorizes that Yuno's mental balance is so fragile that she modified her own memories as a defense mechanism. Meanwhile, Keigo frames Yuki and Yuno as suspects for his murder of Karyuudo.
