EPISODIUM
Under Yamato's order, Hibiki, Daichi and Io rides on the secret train of JP's to Osaka to help find their chief scientist, Fumi Kanno, who has lost contact recently. They are greeted by another summoner of JP's, Hinako Kujou, at their arrival, but the other summoner Keita Wakui is less welcoming of the three fellow summoners and is returning to his mission of hunting down malignant demons. At the Osaka headquarter, its computer system is under attack from the whole Japan's network. At the same time, Hinako receives Keita's death clip, Hibiki instantly concludes that the scene of Keita's death is related to the hacker attack. Although Hibiki asks an operator to inform Keita not to head to the location of his death scene, Keita cannot receive the call due to being ambushed by Gozuki and Mezuki. All four summoners head to the abandoned theme park where the hacker attack originates from.
