Quick note: This story takes place in an alternate reality where Sunset never left Equestria for power, instead, she left it because she felt everypony was turning against her. She also does this at a later point in time from the original Equestria Girls movie, and she is a little older than she was in said movie.

After running away from Equestria, Sunset Shimmer, or as her friends had once called her, Sushi, thought she would live out the rest of her life alone with nothing more than homework to bother her from day to day. All that changed when she soon realized bizarre things were happening around her, along with a mysterious stranger named Jostle Joyride, who then brings her into the world of Stands, magical entities of one's fighting spirit, and a plot of world domination from an unknown enemy.

Together with Jojo and a new group of friends, Sunset must stop this new enemy, or risk losing the world she had come to take refuge in. This is the tale of Sushi's Bizarre Adventure.

This story takes place in an alternate reality where Sunset never left Equestria for power, instead, she left it because she felt everypony was turning against her. She also does this at a later point in time from the original Equestria Girls movie. In this universe, the girls never got their geodes, and so they don't have super powers. Other than Stands. And because Twilight never came over, she never faced the Sirens in a Battle of the Bands.

This takes place between SuShi part 2 and 3.

With this being the case, Twilight Sparkle has never been to the human world, since Sunset never stole her crown.
---I>>>>>>>]
Something strange is happening in the human world. After spending many years honing their new abilities, Stand power, the Sirens have decided it was finally time to put their plan into motion: Their return to Equestria to rule over it with an iron fist. But not all of them agree with this plan and Sonata Dusk, having grown accustomed to this world, turns against them. On the run, she would have to forge unlikely friendships and worse, fight against her sisters and their minions to protect the people of this world.

On the other side of the mirror, Princesses Celestia and Luna, days from retiring as rulers of Equestria, sense the coming danger and decide to hop through it for one last adventure, a rather strange one at that.

“OIII Josuke! I used Za Hando to erase the barriers between dimensions and now I’m a pony! Isn’t that wacky, Josuke?”

Yes, it is. Too bad Okuyasu pulled something else through too.

HapHazred made a joke of this a few weeks ago in the Writers Group forums. I turned it into a story.

Takes place sometime before the ending sequence of Jojo’s Bizarre Adventure: Diamond is Unbreakable.

Expect about 2-3 chapters.

Two sisters. Ancient power. Sealed evil. Thousand years.

Trixie couldn't care less about ancient history. Or so she thought before she got involved in a tangle of ancient evils awakening, a secret cult preparing for its return, and joining with a group of people who share her same abilities. Now she travels across the world along her newfound companions are the Ash Witches. They look for the only power that could hope to stop this ancient evil.

However, as their trip drives them to the frontier town of Neigh Orleans, they will be stopped by a new menace. A sadistic pair of mercenaries who could stop their mission for good. Trixie can save her friends, but only if she can take the impossible choice.

What will she do?
