This summer, we'll find out if TYPE-MOON's Nasuverse and Baka and Test go together like peanut butter and chocolate, because the adaptation of magical girl remix, Fate/kaleid liner Prisma Illya is going to be a very B&T anime. Silver Link (Baka andTest, C^3) is producing the Shin Oonuma (B&T) directed project, with Baka and Test creator Kenji Inoue supervising the scripts and B&T animator Nozomi Ushijima on character designs.
For a couple of non-Baka and Test credits, C3 creator Hazuki Minase is writing, with an opening by Choucho (Hyouka, Gargantia ending).
In the manga, from Fate doujinshi-creator-gone-official Kalmia, a magical girl version of Illyasviel von Einzbern gathers Class Cards. Rin Tohsaka and Gilgamesh are also significant characters, with Shirou Emiya, Sakura Matou,Kiritsugu Emiya and Irisviel von Einzbern around in smaller capacities.
