You have been summoned from another world.

The King, seated upon his throne, stands and speaks with gravity.

"O Hero. Please, save our world."

It seems the Demon King has been resurrected, and monsters have begun to run rampant across the lands.

To explain the territories you must head toward, the King spreads out a single, massive map.

You look at it—and burst out laughing.

"...Wait, the world is a sphere, obviously lol."

That single sentence echoes through the silent palace.

In the next instant:

"What did you say?!"

A group of people, seemingly palace scholars, rush toward you with intense energy.

"Why!"

"Why do you, who have only just arrived in this world, claim to know its shape!"

"This map was completed by our researchers and explorers over hundreds of years!"

"If you say the Earth is a sphere, why don't the people on the bottom fall off!"

""You conspiracy theorist!!""

Upon hearing the details, it turns out that every other person summoned from another world in the past also insisted that "the world is round."

And the scholars have finally snapped.

The King sighs deeply and calms the excited scholars.

"Fine, fine. Then let us settle this."

"One week from now, a debate shall be held in this palace."

The agenda is simple:

—Is this world flat? Or is it a sphere?

Before you can even fight the Demon King, a ridiculous group of people has stood in your way.

Your opponents are the Flat Earthers of this world.

Conspiracy theorists standing in your way before the Demon King.

—Shut them up with our knowledge!
