Saya gets Ranmaru a date, in the form of forensic expert Yukino Shiraishi, who happens to be Saya's upperclassman in her high school days. During Ranmaru and Yukino's date, Ranmaru discovered that the demons who were responsible for the Machida massacre five years ago and for the death of his police comrades were believed to be of European origin, with Yukino filling Ranmaru in on the background on a Western urban legend that the demons were summoned by alchemists in order to achieve immortality during the Middle Ages in Europe. Ranmaru was horrified that the pictures in a book found in southern Italy were the same ones that he had encountered a few weeks ago. During a conversation with Saya, she told Ranmaru that Yukino's late mother was murdered supposedly by a vicious thief. Thinking that Yukino may be in danger since her mother's death was at the time when the Machida massacre took place at the same time, he went back to the forensics building to check on Yukino when a Phantom humanoid appeared in the dark and tried to attack Ranmaru, but a spiritual barrier appeared out of nowhere and dazed the human larvae, forcing the humanoid to fight Ranmaru himself. He was eventually wounded by Sakura's broadsword, making the humanoid retreat in defeat with an arm cut off from it.
