Wouldn't that be two phantasms, one anti-army (the magic pages) the other, anit-unit (the journey through hell)?

The Noble Phantasm is just the gate to a 異界. It can either be used to pull stuff in the 異界 to the place Dante is, or to pull stuff from the place Dante is to the 異界, since it's a two-way door.

That said, Mask didn't do some edits, so don't consider that sheet as finished.
