Curious...the art credit is to "Komuou". When I looked up the kanji string, the first hit took me here. From the inclusion of "Fluffy, Fluffy Reimu" strips, I realized this was Kurobane's page. Kurobane's wiki article says his circle is Komuou, yet the art credit and his Pixiv user name are both "Komuou". So...we credit this to Kurobane?
