Reference excerpt

Hyperdimension Neptunia (超次元ゲイムネプテューヌ, Chōjigen Geimu Neputyūnu; lit. 'Super Dimensional Game Neptune') is a series of role-playing video games produced by Compile Heart and Idea Factory, which revolves around and parodies the real-life video gaming industry usually from a Japanese perspective along with parodies of other forms of Japanese otaku subcultures. The series has also branched off into other forms of media, such as a manga, light novel and an anime. The series debuted in Japan on August 19, 2010, with the video game of the same name for the PlayStation 3, and received sequels: Hyperdimension Neptunia mk2 (2011), Hyperdimension Neptunia Victory (2012), and Megadimension Neptunia VII (2015) as the last of the main series, until the release of Neptunia Unlimited (2026). All previously released main games have been remade at least once (such as the first three as the "Re;Birth" trilogy) and since then multiple spin-offs and crossover games have also been released for various platforms. An anime television series adaptation, titled Hyperdimension Neptunia: The Animation, aired in Japan between July and September 2013. An OVA, titled Nepu no Natsuyasumi, was released in July 2019. A second OVA, titled Nep Nep Darake no Festival, was released in October 2022, and third OVA, titled Hidamari no Little Purple, was released in April 2023.

Setting

Games within the series takes place in the world of Gamindustri (a pun on "game industry"), which is divided into four regions/nations, each ruled by one Goddess CPU: Planeptune, Lastation, Lowee, and Leanbox. Each region is completely different from the others in appearance and atmosphere, with each representing a specific video game console. Lastation represents the PlayStation, Lowee represents the Wii, and Leanbox represents the Xbox, while Planeptune represents the cancelled Sega Neptune. In the beginning of the story, the four goddesses are fighting each other for "shares" in a war known as the Console War. Shares are the manifestation of the belief citizens put into their goddess, and without shares, a goddess dies. Because some of the games feature time and/or dimension travel there are slight differences in the settings for each title.

Development Prior to Q3 2009, Compile Heart was conceptualising a new RPG project centred upon character designs by Tsunako, with the intention of collaborating with a partner company. This game was originally planned to feature three princess sisters and a protagonist. However, the partnership deal fell out, and as a result the project plans were redesigned and eventually became "Neptunia" close to the end of 2009 following the completion of Trinity Universe's development. During the early stages of the project, the characters Noire and Blanc were originally coloured red and blue respectively, however their colour schemes were changed to black and white so that they could better fit in with the new game setting and plot. The release of the first sequel to the original game, Hyperdimension Neptunia mk2, saw the introduction of a reworked game engine and the replacement of various components such as the battle system and dungeons, which were completely rebuilt from scratch. Hyperdimension Neptunia Victory later built on this, with the parts from mk2 which were considered "weak" by the developers removed and improved, eventually setting Victory as the foundation for the design of future titles within the series. Following Compile Heart's collaboration with David Production to produce the Neptunia television animation series, the developers were able to change their approach to direction and script-writing based on their experience with the anime development staff, which resulted in the changes to the narrative found in the Re;Birth games on PlayStation Vita.

Release history Hyperdimension Neptunia is the first game within the series, with the name originally derived from the scrapped Sega Neptune which combined the Sega Mega Drive/Genesis and Sega 32X into one unit, originally scheduled for release in 1994 or 1995 before the project was dropped after the release of the Sega Saturn. There are two sequels which have been released under the names Hyperdimension Neptunia Mk2 and Hyperdimension Neptunia Victory. Another game, titled Hyperdimension Neptunia PP (神次元アイドルネプテューヌPP, Kamijigen Aidoru Neputyūnu PP), was released on June 20, 2013, for the PlayStation Vita in Japan and it was released in the west in June 2014 as Hyperdimension Neptunia: Producing Perfection, developed by Compile Heart, Idea Factory and Tamsoft. During a streamed interview at Tokyo Game Show 2013, Idea Factory and Compile Heart announced that Hyperdimension Neptunia Re;Birth 2: Sisters Generation was under development. Re;Birth 2 was released on March 20, 2014. Hyperdevotion Noire: Goddess Black Heart (超女神信仰ノワール激神ブラックハート, Chō Megami Shinkō Nowāru Geki-Shin Burakkuhāto) with Noire as the main character, was released on May 29, 2014. On March 16, 2014, two new next-generation games were announced, titled Hyperdimension Neptunia U: Action Unleashed (超次元アクションネプテューヌU) and Megadimension Neptunia VII (新次元ゲイムネプテューヌVII). Hyperdimension Neptunia U: Action Unleashed is an action game spin-off exclusively for the PlayStation Vita released on August 28, 2014, in Japan, developed by Tamsoft, whilst Megadimension Neptunia VII is a main series title for the PlayStation 4. At Tokyo Game Show 2014, an enhanced remake of Hyperdimension Neptunia Victory for the PlayStation Vita, titled Hyperdimension Neptunia Re;Birth 3: V Century, was announced.

Games

Main series

Hyperdimension Neptunia (2010)

The game that introduced the series premise. Since its release, the game's story has always remained standalone in the isolated "Superdimension", never receiving a true sequel, as the games from mk2 onwards take place in a separate "Hyperdimension" universe with its own storylines, direct sequels and connected multiverses. The game was remade as Hyperdimension Neptunia Re;Birth 1 released in 2013 with a modestly rewritten story and a combat system inspired more by Victory, Hyperdimension Neptunia Re;Birth 1 Plus in 2018, and Neptunia re★Verse in 2020, which in itself is based on the first Re;Birth game.

Worked examples

Example 1 — a first encounter with Hyperdimension Neptunia

Start with the simplest possible case. Write down what Hyperdimension Neptunia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hyperdimension Neptunia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hyperdimension Neptunia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hyperdimension Neptunia

In research: Hyperdimension Neptunia appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hyperdimension Neptunia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hyperdimension Neptunia is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010 manga, 2013 anime television series debuts, 2013 manga, so understanding it makes those chapters shorter.
In everyday life: Look for Hyperdimension Neptunia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
