Dohoho. Someone beat me to the punch and linked this to an already existing parent while I was trying to make sure I had Eiwa's name right. But yeah this is from Spears of Vision, released at Comiket 72.
I think danbooru must have almost every worthwhile picture on it already. I've gone back and found 7 year old pictures on cd and tried to upload them and it either finds the same checksum or someone parents it in a day.
