>>2594016She is an ice fairy, fairly strong for one of her kind. She first appeared as the second stage boss of popular japanese bullethell games (well, mostly) series "Touhou project". She is often connected to the digit 9, especially enclosed in a circle and the word "baka" etc. referencing her, let's name it, stupidity. One of the most popular character from the series, maybe even the most popular one

That should be enough information for you, now you know who the cirno is
