Lord El-Melloi II's Case Files: Rail Zeppelin Grace Note - A Grave Keeper, a Cat, and a Mage

Lord El-Melloi II, head of the Department of Modern Magecraft Theory at the Clock Tower, gives a lecture to his talented students. After the class and a stormy assembly of the Clock Tower, where a hidden struggle for power unfolds, El-Melloi II returns to his room. In a fit of rage he heaps curses on the other lords, but one of them unexpectedly rebounds on him.

Realizing that the curse threatens his life and that this is no accident but a carefully prepared trap, El-Melloi II launches an investigation together with his loyal companions: his quiet apprentice and bodyguard Gray, the eccentric but brilliant Flat and the composed Svin. They set out to discover who is behind this malicious plot and how the curse can be lifted. Along the way they face dangers and mysteries that heighten the tension and threaten not only El-Melloi II's life but everyone around him.

This special episode is a prologue to Lord El-Melloi II's Case Files, set years after the Fourth Holy Grail War, when Waver Velvet has inherited the title of Lord El-Melloi II.
