Cirno proves that every Boolean ring is commutative

Cirno has a PhD in mathematics.

Here's an educational slideshow. Don't ask me why I made this; all you gotta know is that this won't become a math channel. Well, maybe.
My good friend Emiko generously let me borrow her voice for this skit; I told her to record everything in one take.
Anyway, the pictures were taken in MikuMikuDance using models by arlvit and Maddoktor2. I wanted to animate Cirno properly but it would've taken too long for a shitpost so fuck it.
