This is an "if - maybe" story of a country other than here.

"Black Rabbit Kingdom" and "White Rabbit Kingdom".
"Black" and "white".
Back to back, different worlds.

These two worlds, which should have been side by side as "opposites," never met, perhaps as a twist of fate. It remained unfinished and in an unstable state.

Hajime, the young king of the Black Rabbit Kingdom, is heartbroken by the disasters occurring in neighboring countries.
Prime Minister Haru, his aides Kakeru and Koi who are fighting for the king, Prince Aoi and his bodyguard Arata, are all busy preparing for the upcoming World Conference and the ball celebrating the 15th anniversary of Hajime's reign.

At the same time, in the "White Rabbit Kingdom," at the suggestion of Hayato, who calls himself the Demon King, King Umi, Prince Namida, the bodyguards Yo and Iku, and former soldier and civil servant Yoru were planning to go on a "picnic" to the "Black Rabbit Kingdom."

When these opposing existences , the "Black Rabbit Kingdom" and the "White Rabbit Kingdom," meet, something will be born.
