The Last Lead.The device has a password to input yet, making them anxious that the messenger aren't allies, so Ryōta decides to go alone to the place where the map leads to. Two individuals wearing black overcoats appear at the spot where the device got activated. Later that night, Kazumi comes into Ryōta's house to narrow down the map's topography. Kazumi then starts asking Ryōta what he feels about Neko and strips herself naked while trying to get him to sleep with her. On Sunday, Ryōta arrives at a church indicated on the map, only to find it in ruins. He asks an old lady nearby about the church who states that it was unsuspectingly destroyed, however, there was no news coverage for it. Inspecting the church, Ryōta finds a German inscription on the walls. Suddenly, a police squad appears and seizes Ryōta without questioning. Fortunately, Neko makes it in time to destroy their cars and guns while Kotori teleports the mad chief of police to a tied-up tree somewhere. The girls tell Ryōta not to be so hard on himself and they should combine their strength together. Kogorō gets a call regarding the alien egg. Kana discusses Kazumi's perversion while the others were away. When they return, Ryōta brings intel of the German inscription with some words that were underlined in blood but is still unwilling to turn the device on at their current location. Meanwhile, the lab receives reports about #1107, #7620, and a high school boy (Ryōta) aiding them. Chisato's assistant, Kurofuku, goes to pinpoint their location with the witch, Nanami Tokō, making her appearance.
