The Dark Goddesses from Neptunia VII are too easy compared to the rest of the game and amount of hype they get. You're fighting Gundam sized versions of the Goddesses. You're in a pocket dimension with only tiny floating platforms to stand on. And you can only use your skills. However, that isn't much of a handicap. Your skills are really strong in this game and they only thing stopping you from spamming them is the cost. But lo and behold your SP regens during these fights. And there is EXE and coupling skills that use a completely separate bar and are even stronger than the normal skills.

At least the music is awesome.
