https://neuralblender.com/ Describe your picture in the box and hit Go, then the image will show eventually when it finishes the queue. It may take some time but it will show up, don't need to refresh or anything.
@karolat@cheru@Jack maybe it doesn't know what k-on is, maybe changing the description or something. One time i wrote "Azumanga Daioh" and just drew a pink square
