[Western Crossover] Gotham's Fourth Calamity

You Nailuofulainiya came across a new game called Gotham.

She really liked its world-building feature. The game could even link up with the infinite-flow battle royale next door, and you could invite teammates. How cool was that?

Then an infinite-flow battle royale game inexplicably appeared in her world. Everyone who turned eighteen had to enter it, or they would be automatically erased.

Until she met the superheroes.

A superpowered person appeared in Gotham. She acted strangely and never wore a mask as a vigilante, shining like a star in the night.

She also seemed to have trouble understanding what people said.

Was she dumb?

Not really, considering she was doing a great job as a vigilante.

The Spoiler met this superpowered person for the first time and was given a rose.

"?"

Then she was told, "Wifey, marry me."

She recruited this superpowered person to be a vigilante.

"Want to be a vigilante?"

"Okay."

The heroine's inner self is just an ordinary person, and she won't be killing her way through the infinite-flow world.

Pairing undecided. It might be with one of the Batgirls, one of the Batboys (not Bruce or Damian), the Flash, or no pairing at all. There may also be different endings.

Theme: Why is a raven like a writing desk? Because there's no reason for liking you.
