Hyperdimension Trip

by DarthImotet87

Multiple worlds collide as some of Gamindustri's worst enemies arrive in Earth Dimension to conquer it. Now, Nanashi and Shizuku, having been sent to Gamindustri, must join forces with the CPUs of both Hyper Dimension and Ultra Dimension to save their people and stop an ancient CPU's vengeful bid for global annihilation, as all-out war erupts between the two opposing forces!

1. Chapter 1

Chapter 1: Prologue:

Gamindustri. A world which exists beyond our reality. Where four CPUs rule above each nation.

The nation where CPU Purple Heart rules, Planeptune. The nation where CPU Black Heart rules, Lastation. The Nation where CPU White Heart rules, Lowee. The Nation where CPU Green Heart rules, Leanbox.

In the past, Gamindustri had been exposed to threats such as ASIC, the Deity of Sin, and the CPU of the ancient nation of Tari.

But thanks to the efforts of the CPUs, Gamindustri has seen lasting era of peace and prosperity...until now.

For that peace is suddenly shattered as Neptune and her friends discover a pair of gravely injured otherworlders who's world has been conquered by sinister forces.

As new information comes to light, it quickly becomes apparent that some of Gamindustri's worst enemies are involved.

Rei Ryghts, CPU of the ancient nation of Tari, who nearly brought down Planeptune two years prior, has somehow regained her lost powers, completely swallowing her meek human form, and has vowed vengeance against the CPUs for defeating her. Joining forces with Arfoire and Anonydeath, Rei has conquered the Earth Dimension, in order to build an army of slave soldiers to invade and crush Gamindustri.

Can Neptune and her friends save Hyper Dimension, Ultra Dimension and even Earth Dimension from Rei's tyranny, or will Rei Ryghts succeed in destroying the multiverse itself?! Because on top of everything else, an even greater threat may be lurking in the shadows...

Find out in Hyperdimension Trip!

Disclaimers:

This story is intended for readers 16 years of age and older. It is a war fic, and as such, does contain a some of the following: blood, violence, coarse language, and suggestive themes. If you are under the age of 16, or are offended by such content, please turn back now.

This story is non-canon, taking place in an AU which mostly follows the anime, but mixes in certain aspects, characters and events from the games as well. There may be multiple versions of a character in a certain scene, in which they will be referred to with an acronym representing their respective home dimension before their name (i.e. In scenes where both Hyper Dimension and Ultra Dimension Histoire are present, they will be referred to as HD Histoire and UD Histoire respectively). I also took a few liberties here and there, while also making some minor character personality changes, though, for the most part, I tried to remain faithful to their canon personalities as much as possible.

Examples include the following:

Compa is more serious and less of a ditz, taking a much more active roll in the early chapters of the story.

Plutia is less slow and more articulate, noticeably capable of using words which she would otherwise be incapable of pronouncing.

Rei Ryghts is far more psychotic, and unhinged than even her Ultra Dimension counterpart from Victory/Re;Birth3.

Neptune is more or less the same, with the exception that her habit of breaking the fourth wall is almost non-existent (with a war going on, there's very little opportunities for Neptune to not be in serious mode). Don't worry though, there's still the occasional humorous banter that you'd expect between Neptune and other characters.

Final Notes:

Please be sure to leave a comment. I am not really the best writer, so there will likely be much to criticize. I welcome that criticism, as it is criticism that helps an author to improve as a writer. Just remember to please keep it respectful and constructive. Also, I tend to update irregularly. Please be patient for future updates, and also, do not assume the story is dead just because it hasn't been updated in a while. And also, please do not pester me about chapter updates, as I will ignore your comments if you do. Thank you.
