As he is being charged the apprehension of Dr. Sakaki, Minamoto thinks back to his early days with the psychometric physician and decides to investigate the matter for the real culpable. As Minamoto attempts to convince Taizō against wielding Shiho's psychometry in the investigation, Dr. Sakaki is allowing his libido to get the better of him as he examines a patient—and would have succeeded if not for Minamoto's timely arrival with the affirmation of his participation in the upcoming euphoric nocturnal engagement. After a week of accompanying Dr. Sakaki on his nocturnal playboy adventures, Minamoto finds no sign of impending treachery—nor an avenue for proving it. Frustrated at their leader's obfuscation to their legitimate inquiries, Shiho tries using her psychometry but is foiled by an active device that guards against telepathy and psychometry. As the girls summon Naomi as well as Natsuko and Hotaru to act as a deus ex machina, Kugutsu even gets into the act by creating a life-size doll of Minamoto to throw off the girls—who are neither deceived or amused at the mirage as they rush out after their leader. The girls' first stop is at B.A.B.E.L. Headquarters where Taizō explains the whole story behind Minamoto's strange behavior as of late and gives Kaoru Minamoto's limiter release device after they free Ichirō who then guides them to where their leader is. Meanwhile, at the dinner date, Minamoto is starting to put two and two together. Kugutsu wants to effect the mirage of Dr. Sakaki being a spy in order to have the Doctor slain without getting his hands dirty—a qualm that the desperate Kugutsu has quickly abandoned as he prepares to finish off Sakaki. Fortunately, Kugutsu's bid for revenge implodes on itself when Ichirō guides Kaoru and her teammates to Minamoto to quickly finish off the remaining waitstaff dolls before leading Shiho and Aoi up to the roof (after Minamoto releases their limiters) to do battle with Kugutsu while Natsuko, Hotaru, and Naomi are all guided through successfully saving Dr. Sakaki's life.
