Doujinshi circle of Furari and Kome Dorobou. They frequently pick on Shinki.
From their answers to webclaps of January 29, 2011:
ところでフラリさんと米泥棒さんは違う人なんですか…？
え、何暗黙の了解…？いいや限界だ、聞くね！＞背の高い方がフラリで低い方が米泥棒です。
イベントでブースに立ってる二人がそうです。
By the way, aren't Furari and Kome Dorobou the same person?
Oh, what? An implicit understanding? Whatever! I'm at my limit! I'm asking you! Now! (A quote from Kira Yoshikage)> The tall one is Furari and the short one is Kome Dorobou.
Two people on our booth at events are actually us.
