[Western Crossover] She Comes from the Island Where Everyone Gets Beaten Up

OOC warning

The female lead is a chibi character.

The timeline is all over the place, and mainly serves the plot.

Second-person narration.

A children's-story style.

The female lead isn't perfect or a powerful, flawless heroine. She makes mistakes.

-

You wake up one day in a city called Gotham. Looking at its gloomy streets, you decide to change it.

-

One night, Batman corners a criminal, his tall, terrifying figure slowly looming over them.

Just then, a butterfly net slams hard into his back.

He turns around and sees a tiny figure, about three heads tall, holding the net.

You, the tiny three-heads-tall figure: I refuse to let scary residents like you live in my city. (Whack!)

Batman, who has always considered Gotham his city: ?

-

The female lead has a boyfriend, but this story is mainly about her adventures, so it's tagged as no-couple.

Theme: Happiness! Joy!
