Lord El-Melloi II Sei no Jikenbo: Rail Zeppelin Grace Note EP3 - Thunder and the Underground Labyrinth

The rowdiness of the classroom seems like how it usually is in Modern Magecraft Theories, but there is something wrong with Lord El-Melloi II's behavior. Luvia, who had come to visit and attend one of his lectures, asks Gray the reason why, and it turns out it's because his favorite tearoom has basically closed shop. Lord El-Melloi II heads to the tearoom to inquire on their circumstances as he realizes work just can't progress at this rate, but when he goes down into the sewer system to investigate, an ominous shadow attacks him. Gray, worried that he hasn't shown any signs of returning from the investigation, seeks help from Flat and Svin.
