Detailing everything to Kogoro about the witches, he agrees to analyze the medicine molecular structure and look for a way to synthesize them; unfortunately it may take half to several years. Also Ryota has him look at the fertilized alien egg. The girls are glad to rely on Ryota; Kana states that Ryota likes Neko. Some classmates invite Neko to karaoke, though she gets flustered for singing in public. Ryota tutors his next-door neighbor Kitsuka. Next day, Kotori tells Ryota rumors that the lab was founded hundred years ago by alien ruins, and powerful aliens that can destroy humanity. Chisato reports to the higher-ups that after interrogating Kikako their top priority is to capture #1107 and retrieve something known as the Grane. Ryota takes Kazumi to Akihabara to find equipment for the observatory's computer although she acts that it's a date. He later takes out the communication device, turns it on, broadcast a map in German language. Kazumi translate it says "Kill the witches now. Only then will we reveal the truth."
