Hyperdimension Neptunia was a 12-episode fantasy/ comedy TV anime that aired from July 12 to September 27 of this year. The series is an adaptation of a video game RPG series developed by Idea Factory and Compile Heart, with the anime adaptation being created by David Production. Funimation currently has North American streaming rights to the series.
In the virtual world known as Gamindustri, the four goddesses of each country agree to a “friendship treaty” that bans each country from using military force to gather Share Energy, an energy source that grants a goddess influence and power over any territory in Gameindustri where their populace strongly believe in them. While the goddesses learn to get along with one another, they have to face enemy threats attempting to exploit Share Energy for their personal gain over the world of Gameindustri.
Neptunia is yet another case of an anime series shamelessly being used as promotional material for its video game source material. It also panders fairly heavily to the otaku crowd with its milking of the moe craze for its female cast and nods to the video game industry coming from characters, country names and elements to some of the worlds that the characters visit.
All the characters seen throughout this series milk differing character archetypes that they don't really grow out of and have little depth to show for it, many of said characters milking differing character types that have become popular from the moe craze. Much of the female cast serve to pander to its audience with their character quirks, idiosyncrasies, revealing or fetish-themed outfits (these especially prevalent with the transformed states of the goddesses) and usually getting into suggestive predicaments during comedic or serious moments.
The series also panders to video game fans as character names, countries and elements to the worlds that are visited by the characters are nods to past and present elements of the video game industry. For instance, Neptunia and Neptune are references to Sega's canned attempt to create a Genesis/ 32X combo video game system called the Neptune, and Nepgear being a nod to Sega's handheld game system from the 1990s called the Game Gear.
The series attempts to mix comedy and adventure in its focus on the goddesses focusing on the group either bonding in crazy predicaments involving whatever video game nods that are referenced or dealing with any random enemy threat either causing trouble for anyone among their group or attempting to whore up Share Energy for their personal gain. Both elements to the title's storytelling are hard to care for because of Neptunia's shallow characterization and a number of the villains in the series being hard to take seriously as threats because of their comical behavior or incompetent actions. Even in the instances where the group have to deal with a serious threat, Neptunia quite often milks plot devices that are either too convenient or milk the tiresome “power of friendship” cliche to thrash the enemy they confront.
