Defeat Monsters! is the fourth plot scenario in Hyperdimension Neptunia.
The party doesn't leave immediately, they stay in Planeptune and fight off more monsters despite IF wanting to hurry on to the next landmass. The girls deal with yet another Sand Worm monster, and Neptune and her party encounter a mysterious woman who suddenly attacks them without reason. The party defeats her and the woman deduces that the reason she lost was because they were on Neptune's home turf, Planeptune. She states that it will not be like this next time and leaves. IF questions what her problem is, thinking that she was probably menstruating or something.
