Prevents the excessive use of "..." and "♡".
The year is 2120 AD.
Japan was a peaceful country.
But one day, that peace suddenly ended.
The heart of the government was seized by an unidentified organization, and Japan split into 47 independent nations.
Each prefecture armed itself, staking its pride and future.
Furthermore, the "Prefectural Sacred Treasures" that had been dormant across the country awakened, granting supernatural powers to each prefecture.
A broadcast then aired nationwide.
"The right to govern Japan will be granted to the prefecture that survives until the end."
From that day, the greatest war in Japanese history— the "Prefectural War"— began.
And just two months after the start of the war...
The flames of battle scorched the Japanese archipelago, and 32 prefectures vanished from the map.
The currently surviving prefectures are as follows:
Makuhari, Chiba Prefecture.
There was a boy staring at the ruined city. Haruto Kobayashi (18).
Haruto does not want conflict.
Even so, he resolves to fight to protect those dear to him.
"I'll end this war. If that's what it takes, I don't care if I have to make the whole country my enemy."
At that moment, Chiba Prefecture's Sacred Treasure awakens.
Ability—"Link."
A unique ability to temporarily borrow the powers of other prefectures.
Meanwhile, in Tokyo, the representative of Tokyo known as the strongest, Shin Kanzaki, smiled quietly.
"Only 14 prefectures left until national unification."
Thus, the battle for the fate of Japan begins—.
