Choujigen Game Neptune: Sisters vs Sisters (超次元ゲイム ネプテューヌ Sisters vs Sisters, lit. Super Dimension Game Neptune: Sisters vs Sisters), also known as Hyperdimension Neptunia: Sisters vs Sisters, is an orthodox spin-off RPG for the PlayStation 4 and PlayStation 5. This game follows Nepgear and the CPU Candidates waking up to a Gamindustri two years after the Buzzoer Phenomenon terrorized the four nations.

Story

Handhelds vs. smartphones—the little sisters’ portable revolution that began over time…

That day, the four CPUs set off in response to a request for help from the PC Continent far beyond the sea, while Nepgear and the other CPU candidates that stayed behind visited a certain research facility.

There, they were trapped in a capsule and put into a deep sleep by the “Gray CPU,” and awakened to a Gamindustri two years later.

People now had the latest model of smartphone, called the “MagiPhone.” It became a world in which the market share was dominated by smartphones.

Nepgear is told that Planeptune fell to the “Buzzoer Phenomenon,” in which hordes of monsters to appear, and that her older sister Neptune went missing.

Having lost her sister and a home to return to, Nepgear fell into despair.

This is a story of destruction and restoration, by CPUs, for CPUs, to pave the way from a future of despair, to a future of hope.[2][3]

Hyper Dimension

Nepgear and her friends live in a world called "Gamindustri".

The land under Purple Heart's protection, Planeptune.
The land under Black Heart's protection, Lastation.
The land under White Heart's protection, Lowee.
The land under Green Heart's protection, Leanbox.

The four nations were affected by the "Buzzoer Phenomenon", in which a massive amount of monsters appeared, and now the people refrain from going out, leaving the streets deserted.

Probably due to the advent of smartphones called "MagiPhones", that are affecting the Shares ratio, the access to the world called "Ultra Dimension" has been severed.

With the direct communication's means cut off, now the people are connected through their smartphones.

It's said there is no person who doesn't own one these days.
As they are used for SNS, games, and assistant functions, people's dependent on them.
