I thought the lettering on it had been done by spacealien_vamp, like so many of my icons, but since I didn't credit her on my icon page, maybe I'm misremembering?

You remember correctly, I did make that one. It was shortly after I purchased my embroidery sewing machine and before I loaded Japanese fonts onto my computer, because I had to get the kanji by taking a screen capture of the sewing machine pattern-making software.
