The difficult issue Reines and Melvin brought up with Lord El-Melloi II was a case involving a former student of his, Mary Lil Fargo. Mary is the only daughter of the Fargo family, a branch of the Animusphere family that rules over the Astromancy division. Responding to Mary who felt she needed her former mentor's assistance, Lord El-Melloi II and Gray visit the Fargo estate to witness the dismantled corpse of Mary's father, Ernest Fargo. Disjoined from traditions of Astromancy, the crime scene is representative of Modern Magecraft. Lord El-Melloi II dives in to elucidate the matter.

One peaceful day, Gray heads by herself to see Reines. With an unexpected turn of events, the two head out to Carnac, an established department store, to go shopping. Not accustomed to shopping in a department store, Gray continually is at Reines' mercy. Furthermore, Luvia coincidentally joins the two midway, causing the three girls to start a tea party.

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.

As Adashino's deductions are playing out, Lord El-Melloi II makes his comeback. He sees a clue to the identity of the true perpetrator of Trisha's murder from Gray's testimony, and requests Melvin to delay the Mystic Eyes Auction from starting. His objective is to seek assistance from Olga Marie, and grasp conclusive evidence to overturn Adashino's deductions. Meanwhile, in London, Shishigou gathers up Flat and Svin in order to proceed with certain preparations. As each of them reflect upon their own ideas, the fated Mystic Eyes Auction finally begins.
