Latest in the virgule-abusing Nasu-verse franchise is the title-is-a-mouthful/is-that-capital-i-or-small-l Prisma Illya, an alternate universe offering focusing on the mahou shoujo antics of Illya, Rin, and some new characters. I went into it expecting Carnival Phantasm-style screwing-around comedy, but was surprised to find an action-packed series along the lines of Mahou Shoujo Nanoha.
The combination of Ueda Kana and Itou Shizuka are hard to resist as Rin and her ojou-sama rival Luvia; Choucho does the OP. Prisma Illya shows genre awareness but thankfully it’s an earnest entry rather than a nutty parody, and the Fate characters cameo but don’t derail the story. And the action is well-animated and excellently designed: Rin, Illya, Luvia and Miyu battle the Alter versions of Fate/Stay Night’s Servants (Assassin makes a very brief appearance) with all sorts of tactics and pyrotechnics. It’s a short series too, making Prisma Illya an enjoyable confection.
