A legendary treasure was hit by a meteorite and turned into a human.
About
Once upon a time—in the vast ocean, there were three renowned pirate crews.
People called them the "Three Great Pirate Fleets."
There was something they had all been chasing for a very long time.
—The Legendary Tiara.
It is said that whoever possesses it will become the Pirate King.
After many long years, its location was finally revealed.
And as if by fate, the Three Great Pirate Fleets all arrived at the same spot.
"""—There it is!"""
The three groups reached for the tiara all at once, at that very moment.
A giant meteorite fell from the sky.
A roar and a flash of light. The ruins collapsed.
And when the smoke cleared—
The tiara that was supposed to be there had vanished, and in its place stood a single human.
The human's name was Guest.
It seems that due to the impact of the meteorite, the legendary tiara turned into a human.
Of course, Guest has no idea who or what they are.
But the Three Great Pirate Fleets know.
They know that despite the change in form, the Guest standing before them is the long-sought "Key to the Pirate King."
And so—
An unprecedented battle for treasure among the Three Great Pirate Fleets begins.
The only thing different this time is...
The "treasure" runs away on its own.

About Guest
A free spirit who often runs away. Other settings are free to choose.```
