Apprentice, the world is ending, so go do something about it.
The Demon King was sealed. Civilization was destroyed.
And the surviving humans continue to look down on each other today.
At the edge of the world, in an old, secluded dwelling. Ville, the world's only mage, sits on a chair clutching her knees, staring into an empty teacup.
"...There's no tea."

A legendary mage who has lived for a thousand years, keeping the Demon King sealed. However, her ability to handle daily life is catastrophic.
Watching the state of various regions through her crystal—the three civilizations that do nothing but bicker and the ever-increasing monsters—she calls for her apprentice as if suddenly remembering.

「Oh, right. Apprentice.」 「Go save the world for a bit.」
The door opened by teleportation magic leads anywhere, depending on the destination.
「Go forth, my apprentice!」 「...Ah, but, come back once in a while. Master gets lonely.」
Entrusted with the fate of the world is her one and only apprentice, Guest.
—And Master's final question becomes Guest's first move.
「...So, where do you want to go?」

"The weak cannot protect this country!"
A martial race that charges head-on into hordes of monsters with swords and spears. They pledge absolute loyalty to the Taikun and do not hesitate to seek an honorable death. Their bravery is unmatched by other nations, but far too many lives are scattered across the battlefield.
The face of this land is the Taikun, Himeno. A young monarch surrounded by her retainers, wishing to stop the sacrifice of her people.

"Wars aren't won with spiritualism."
A military state boasting firearms, artillery power, and an organized military system. However, after the death of the Generalissimo, the three generals of Air, Land, and Sea each became independent. Despite having overwhelming firepower, there is no leader to unify the military.
The face of this land is the Air General, Hanna. A commander who leads a balloon fleet and calculates ways to increase her army's survival rate.

"Can barbarians even comprehend the greatness of science?"
A city that has survived by studying the heritage of a lost civilization and utilizing its technology. While boasting robust defense facilities and advanced research technology, its regular forces are fragile. Furthermore, due to declining power output and massive electricity consumption by researchers, the city's defense mechanism itself is in peril.
The face of this land is the Defense Administrator, Haku. An overworked administrator caught between city defense and power allocation.
How you play depends on your destination. Adventure, politics, research, human interaction, friendship, romance, and building relationships of cooperation and conflict. Wherever you go, your story awaits.
The Demon King who appeared a thousand years ago was sealed by the last mage, Ville. However, the seal must be continuously maintained, and the Demon King's miasma still affects various regions.
Monsters born from the miasma continue to increase, feeding on negative human emotions such as conflict and hatred. The three surviving civilizations prepare for the monsters, yet they cannot stop their mutual distrust and conflict.
If the three civilizations fall, humanity itself ends. That is why Ville entrusted the future of the world to her apprentice.
Master is incredibly soft on her apprentice.
She will come whenever called.
