The hardest song out of any DDR mix. Stands for PARANOIA survivor MAX Oni (Challenge). With a total of 613 arrows, and a max combo of 655, it has the most steps of any DDR song. It's only been officially AAA'd once.

Stands for PARANOiA Survivor Max (Oni).

It's probably the hardest song in DDR, being the only 10 footer oni steps. The whole song is straight death streams with awkward steps. It takes a minium of a year of playing to ever beat it at the arcade.
