One day, I woke up to find an unfamiliar screen displayed on my smartphone.

It looked exactly like an RPG status screen.

I checked, thinking I might have downloaded some game, but something was off.

The name displayed wasn't "Ammon," which I always use for games, but my real name, Mikado Nose.

What's more, the only thing displayed in the skill section was "Gacha 1."

What exactly is "Gacha 1"?

This is a story about a protagonist who, armed with the utterly useless battle skill "Gacha 1," fights against monsters to survive in a world transformed by the First Break.
