An "expert" difficulty level on Beatmania IIDX. Can be accessed by holding down the VEFX button on the arcade machine while selecting a song.

According to Konami, the word "Another" means "insanely difficult" in the Beatmania IIDX series.
I gave a toy in my store like three glances because it said "another" and it made no sense to me.
