[Western Crossover] Star Rail Secret Identity: Open for Business

The space-time traveler Una passed through the Honkai: Star Rail universe, and when she came back out, she discovered that some heartless jerk had turned her spaceship into a wish-powered energy source. ==

From then on, Una put on secret identities and embarked on the road to collecting wishes (forced to work)

[Gotham's Dream]

The Elation Walker grinned at the camera and announced that the game had begun. The Sparkle virus was spreading through the city.

The Songster of the Galaxy held out a feather to the knight. "I can help you, Mr. Batman."

And so, the Dark Knight accepted the outsider's goodwill. "From now on, fight alongside me, Robin."

[Justice League]

A warrior in silver armor flew down from the sky, saving people attacked by Parademons. A male electronic voice sounded from inside the armor, cold but gentle.

The new hero fought alongside the newly formed League on the battlefield and, naturally, received an offer from the Justice League afterward.

The girl inside the armor was silent for a moment, then asked carefully, "Do you accept short-term positions?"

[The Death of Heroes]

Darkseid's Anti-Life Equation ravaged Earth. A genius in an azure qipao walked across the desolate land.

This world's next generation of guardians watched her warily with immature green eyes. The woman merely lowered her gaze coolly, her eyes green as water.

"He's extremely valuable for research."

Behind her stood the other person's father and brother, who should have been dead. Bruce raised his lifeless blue eyes, reflecting his child dressed in a Batman suit.

[Justice Lords]

An idealistic martyr came to the world of the Lords and joined forces with the knight to reclaim the people's freedom. After it was all over, his companion asked why he had offered to help.

The man with a celestial ring above his head replied, "I can feel the discontent in those people's hearts. A rule that brings people pain isn't the 'order' I want."

"In the paradise I envision, everyone should have a place of their own, and everyone will find fulfillment. They will live wonderful lives under the protection of order..."

The others felt the sky collapse after hearing that. How is that any better? People wouldn't even be allowed to have their own wills!

Can their universe even be saved? They escaped the wolf's den only to enter the tiger's lair!

The Death Saint holding a meet-and-greet at Arkham Asylum (Arkham Knight), the Pathstrider demigod bundled up and carried off by Batman after being defeated three to one (Court of Owls)... Una's journey continued, reaching from the end of time to the world beneath her feet.

[Special Guest/This Secret Identity Isn't Quite Right] (Lycaon)

A handsome furry in a butler's uniform was stopped by a green-eyed child. "Father, he's exactly the butler I need."

Warnings:

The Justice Lords world may be misleading in its blurb. I'll make up for it and tie up the blurb's loose ends in an extra chapter with an if storyline!

* This is my first quick transmigration story. When I started writing, I never expected it to be signed and published. The writing is very immature, there's no technique to speak of, and it's extremely amateurish. The characters aren't any smarter than the author, and the author has no brains...

* Quick transmigration, jumbled timelines, and plenty of stereotypical fanfic tropes. Most DC characters will use the versions I like best. The Honkai: Star Rail characters also have a lot of headcanons!

* All Honkai: Star Rail characters are the protagonist's secret identities. Her identity is never exposed, and she's extremely powerful and invincible.

* The third world, featuring Castorice, will include a fan-girl segment and shipping. There will be some fake Batman/Bruce pairings and other mentions. I'll include warnings in the subtitles, so please take care!

The Court of Owls x Tirisias chapter chooses to deny that Lincoln is Wayne's son, and Lincoln dies at the end. Please skip it if that bothers you!

* Major OOC warning!!! Protagonist-as-a-tool warning!

It's called quick transmigration, but the story actually contains a lot of the Batfamily, and treats villains like the Joker unfavorably.

* This story has a 50% plus 72-hour anti-theft setting. Feel free to skip between worlds. The quick transmigration stories are relatively standalone, so you won't be confused.
