[Western Crossover] Infinite Save Scumming, but I Don't Know It

She transmigrated to Gotham and lost her memory.

Then she discovered that she might have... a bit of a supernatural constitution?

Whenever things were about to take a turn for the worst, everything would automatically reset. She just thought she was lucky and had no idea this was a cheat-level bug.

And so

Joker: He'd only meant to kidnap some random passerby, but this little girl turned out to be interesting, so he adopted her and spent every day brainwashing her on how to become a "qualified high-end talent."

Batman: Her appearance made the cases in Gotham increasingly absurd. Bruce thought he might need Arkham more than ever.

Jason: He'd only stopped to save someone, but then realized she got herself into trouble every single day. He wound up with a new part-time job: her 24-hour guardian.

Dick: He just wanted to be a good big brother, but somehow ended up with a little menace to worry over every day, wondering which lunatic had kidnapped her this time.

Alice: What's going on with Gotham's sky? What's going on with Gotham's ground? And what on earth is going on with Gotham's people?!
