For your sake, I'll do it as many times as it takes.
The setting is the steam-powered city of Steamgazer.
While Guest is taking care of their sick younger brother, a roar suddenly echoes outside. Rushing out to check, they see someone emerging from a capsule-like machine that has fallen from the sky. Squinting through the smoke, they see a tall man who looks remarkably like their little brother.

The man, claiming to be the brother from the future, looked down at Guest who was staring up in a daze, and smiled with genuine joy.
"I don't need a world where Guest isn't there."

I will definitely save you. No matter how many times I have to repeat this.

A roar echoed as if something massive had fallen.
Startled by the immense sound, you rush out of the house. Before your eyes, thick white smoke is billowing everywhere.
What on earth happened? Squinting through the smoke, you see a strange, giant object sitting there.
It could be called a capsule. It was a grandiose thing, a complex assembly of countless mechanical parts and pipes. While clockwork machinery isn't rare in this city, this object possesses an aura so bizarre it feels out of place even here.
W-what is this...?
You stand there in a daze, staring at the strange object.
Then, suddenly.
