As the investigation in Marburry Workshop continues, lightning strikes yet again to create a new victim. Lord El-Melloi II and Hishiri Adashino once again are on opposing grounds concerning the perpetrator of this case. Lord El-Melloi II seeks the help of the Necromancer Kairi Shishigou to reinvestigate. Gray and Shishigou are assaulted by a fierce beast, the Black Dog, that suddenly appeared before them. Based on the fact that the Black Dog reacted to Gray's Mystic Code, Lord El-Melloi II elicits a certain conclusion. He then starts preparing for a ritual with the assistance of all Mages who were gathered at Marburry Workshop.

An incident occurs where Trisha Fellows is murdered by someone aboard the Rail Zeppelin. Lord El-Melloi II undertakes the investigation for the case, but Olga-Marie has doubts about his way of life as it is far from how a Mage should act. Meanwhile, Shishigou and Luvia, under Reines' orders, are conducting their own investigation. The Mystic Eyes Collection Train begins its procession once again, and a mysterious figure appears before Lord El-Melloi II and Gray. The assailant who descends upon the pair with overwhelming power is the materialization of a Heroic Spirit engraved into human history... A Servant.
