COY stands for Cross Over Yuri. The premise is pretty simple, I have a list I've compiled of over 500 cute girls from various anime and manga. I then use a random number generator to make pairing, which I then draw. Every third picture is a threesome.
This was the first official COY, meaning it's the first to be generated using the random system described above. And what a doozy of a first pairing it is! Two of my favorite anime, Dragonball Z and Azumanga Daioh, meet with my favorite girls from each show. Wow. In hindsight, though, I kind of wish this pairing had popped up later, as my art really wasn't that strong back then. Oh well, nothing saying I can't take a crack at this crack pairing again later!
