I'm a little bit afraid for beezelbub since it's location this week in WSJ is 13 http://kidoailakutrad.free.fr/ as you can see on the right of this page is a shonen jump section which I believe the order of the series is the order of this weeks rankings the current rankings for beezelbub isn't looking to good but hey at least it's doing better than the ones below it.
I'm not really sure, but an issue with color pages means it's unranked. I don't think I've seen Beezlebub going any lower than 10 so it's actually doing very well compared to the other series that started around the same time like Hoop Men which was canned this week or Medaka.
