Lord El-Melloi II is pissed, and he doesn’t hesitate to take it out on one of his more talented but insolent students, Flat, with a head-grabbing move that another student, who looks like a magical girl, has patented it. Meanwhile, a new student, Luviagelita Edelfelt, is not amused, and asks Gray what, exactly, is the lord’s deal.
In continuing with the domestic comedy that surrounds him, the source of Waver’s foul mood is the unplanned closing of his favorite coffee shop due to an electrical fault. As a loyal and enthusiastic regular, he offers his services to track the cause. Turns out one of the exterminators the owners hired went missing into the labyrinths beneath the shop.
El-Melloi’s investigation leads to an encounter with some kind of lightning-aligned beast, and when he fails to return to the coffee shop, Gray is called, and Gray calls Flat, who along with his classmate Svin meet Gray in the tunnels to search for their professor.
They locate him, a bit beaten up but otherwise fine. Svin takes him above for medical attention, while Gray and Flat follow the illuminated tracks of the monster that attacked the lord. They eventually encounter that beast—a kind of giant demented electrical rabbit—and Flat shows he’s no slouch when it comes to magical barriers, making a good team with Gray.
They eventually reach the source of the monster: the workshop of a Clock Tower zoology mage, Gurdoa Davenant, who sees the death of the exterminator and others to be a small price to pay if he can reach the Root. He summons several more rabbit beasts that surround the students, suggesting an excellent battle is about to take place.
Unfortunately, Lord El-Melloi returns with Svin (in his own form of beast mode) and a bunch of documents tying Gurdoa to a number of crimes for which the Clock Tower has frozen his assets and declared a warrant for his arrest. It would seem the modern world cannot bear mages like Gurdoa, willing to break the rules of magecraft to pursue his own lofty designs.
He later admits to his students he was partially bluffing and probably would not have been much help if Gurdoa didn’t go peacefully (which he does), but I imagine if he’d let Gray, Flat, and Svin let their collective hair (and hoods) down, they could have put on quite a show. Instead, it’s a much more subdued (and thus boring) resolution.
This episode’s case file was okay, but nothing to knock one’s socks off, especially after the spectacle of Gray unleashing her power (and as-of-yet unspecified connection to Saber). However, the post-credits scene bodes well for some future excitement: according to Luvia, two positions for Association participants in the Holy Grail War have closed—not something El-Melloi wants to hear.
