Hyperdimension Game Neptune ~Megami Tsuushin~

There is a parallel universe called Gamindustri. A long time ago, in Gamindustri, a big incident took place. But the conspiracy of the 4 continent's Guardian Goddesses (Hard), crushed it and brought peace. This is the story of what happened after the Goddesses resolved the incident.

Based on a video game series which pokes fun at several facts and details of the gaming industry; even to the point were character names are affected. For example "Neptune" is a reference to Sega's cancelled "Neptune" console.
