Not sure if anyone else has been around to see this, but I spotted an advertisement for Ayumi's Mirrorcle World single in Second Life at the avexisland sim a couple of days ago.
It's strange that they haven't posted this there until now because back when the single came out ads for BoA's new album were everywhere in the sim.
Yup, Avex has a sim in Second Life, but usually I don't see anyone there. (I'm assuming it's because of the time difference...and there's no music playing.

) If you're in SL and want to see, just go to the Map and put in "avexisland" as the region name.
