At first it looked like one of Kyouko's Mirakurun doujins from Yuru Yuri, then the "anti-magic" got dropped and I was reminded of Nanoha. I thought "NanoFate science babies would be a great idea!" but there's already Vivio.
I've known of Little White Butterflies for years and years and years, and I've seen some horrific shit from them. Once in a blue moon though, something vanilla, or almost vanilla, comes out of 'em, despite the fact that they've spun off Team Vanilla as a dedicated vanilla group/brand/whatever.
