The only new volumes I got were the Cotton-Drifting arc (numbers 3 and 4) and the last volume of the Atonement arc (volume 18), so my volume count goes up to 48, though it'll be 49 around the end of the month, as the first volume for the Massacre arc is being released in a couple of weeks, and I preordered it a few weeks ago. All I need now is the Time Killing and Beyond Midnight arcs and my Higurashi manga will be up-to-date. (May or may not get Demon Exposing arc in the future.)

EDIT: Damn, Dark Absol! I don't think I know anyone with that much manga ever O_O. Where are you keeping all of that?
