@allison @kaia she's a magical ice fairy from a series of shitty bullet hell shooter computer games that became a massive meme in japan back in the 2000s and by the 2010s had spread all over the internet. autistic japanese internet users gave meme personalities to the dozens of characters (all of whom are little girls with magic powers btw) because they barely had any personality to begin with. cirno's thing is that she's an idiot tomboy and can't do math. yw
