Yep, just read the Ch 2 of Kamio Yui and this is one of the easiest drops of WSJ manga I had in the past year. Very dissapointed by Hiroshi Shiibashi since I am a fan of Nurarihyon and I also liked Illegal Rare. This cannot compare to either of these.
Sadly, it is in a very good position (and Saiyuki as well which I started to like a lot) unless it somehow really gets hated by the readers. For now, ne0lation and Gokutei Higuma are struggling big time, David-Kun is doing awful in sales, Souma is....Souma. And there is Hinomaru Zumou constantly lurking with it's erratic positions, low and stalled sales, and an anime which flopped big time.
