: The OVA is notable for including almost every major witch and side character from the series in various costumes (such as Nene Odagiri in a yakisoba-themed outfit).
: The central plot revolves around the Supernatural Studies Club members— Ryu Yamada , Urara Shiraishi , Toranosuke Miyamura , and Miyabi Itou —forming a temporary pop group for the school festival.
The episode is widely regarded by fans as a high-energy "fan service" piece—not in the ecchi sense, but in its dedication to showing the cast in diverse outfits and lighthearted scenarios.
: While primarily "for fun," the episode includes cameos of characters from the manga's second arc, such as the archer girl who shoots at Yamada, which were otherwise skipped in the 12-episode TV adaptation.
