Field Day starts orderly enough, with members of Class 2 and Class 1 exchanging pleasantries, and Yunyun, apparently from “Class 3” challenging Megumin to a battle (turns out she’s the only member of Class 3).
From there, a series of contests from tug-of-war to…donut grabbing(?), to the cavalry battle. The latter is worth 100 million points, rendering all the previous exercises and their somewhat random pointless.
Then the teachers join in, with Roswaal, Vanir, Pandora’s Actor, and a reluctant Rerugen wondering what he’s doing with these weirdos. Classes 1 and 2 decide to join forces to beat back the faculty, who then deploy their trump card, the Mobile Fortress Destroyer from KonoSuba.
While the show should be lauded for bringing in so many more familiar faces, it’s odd that Class 1 is only around half the size of Class 2 (though “Class 3” is a good joke), and for an episode with so much activity, there’s precious little action, which is to say…animation, only the suggestion of it through panning montages.
