Finally! I drew this sometime last month as a birthday present for Honigmilch, but it was to be a surprise so I couldn't upload it until now. XD
We didn't have any Onigiri at her party, but there was sushi, so no complains on the japanese food front. The kanji and kana, btw, read "neko no onigiri" which translates to "cat's riceball", although the riceball part is not entirely correct... whatever!
