Murder aboard the Rail Zeppelin! Someone has killed Trisha Fellows, and Lord El-Melloi II steps up to take on the case himself, but Olga Marie questions his way of life, as his behavior is far from typical for a proper Mage. Meanwhile, Shishigou and Luvia, under Reines's orders, are conducting their own investigation. The Rail Zeppelin begins its procession once again, and a mysterious figure appears before Lord El-Melloi II and Gray. Radiating overwhelming power, their assailant is a manifestation of the Heroic Spirits engraved into human history: a Servant.
