The year is 2661 CE. Ten years ago, Bashin Dan became the trigger that stopped the Earth from resetting itself. On the anniversary of this sacrifice, Barone and Clackey hold a conference, celebrating the union of Mazoku and humanity, and also Dan's feats.

However, beneath that peace, an organization named Cardinal Sign advocates for the subjugation of Mazoku and human supremacy. They resort to terrorist attacks, violence, and have somehow obtained the 12 Zodiac X-Rares which ought to have vanished together with Dan.

Amidst all this chaos, the bearers of the core's light feel a weird sensation, one that they've felt before. What could be the meaning of it, and what is the meaning behind the card that appeared within their decks, named "The Clash King's Miracle"?

西暦２６６１年、地球。

人類と魔族の統一政府による統治が続く中、

新たな組織が不穏な胎動を始めていた。

そのひずみは各地に広がり、

かつて馬神弾と共に世界を救うために戦った

仲間たちにも届きだしていた…。

馬神弾が地球を救い、光となってから１０年。

果たして〝平和〟はもたらされたのか、それとも。

バトルスピリッツは新たな歴史を刻み始める。
