Hyperdimension Neptunia Victory II just came out in Japan. We’re still we’re waiting for a publisher to announce an English version, but in the meantime check out the opening video for the PlayStation 4 game.
Compile Heart is preparing downloadable content for the game like consumable item packs and in May there is an event called "The Neptumaster." The Neptumaster is a free download where Neptune and the CPUs have to battle a dubious idol group which has a Noire, S-Sha, and… Arfoire? or at least characters that look like them together.
