Artist is 紫(ユカリ)[Yukari] but that's a common enough name that I don't quite want to turn it into an artist tag. Most characters with it should be tagged full name, but even so... Thoughts?
Circle is 子猫猫像(こねこねこぞう)[Konekonekozou], so maybe we can use that? I'm going so for now, a mod can correct if they decide on a different course of action.
