Story

With the Westernisation of Japan now far in the past, it is now the Taishou Era, where Japanese and European cultures mingle freely. The stage is set in the flowering imperial capital, Tokyo. Shrouded in death and darkness, an unprecedented event happened to the era that brimmed with romance and hope.

A portal known as the Dark Gate had suddenly materialised, and from it emerged mysterious troops by the name of the Black Spirits.

With hatred embodying soldiers, weaponry and the like, only the power of exorcism stood a chance against the Black Spirits—only those in the Kagura Bukan are in possession of such power.

Using swords to drive away the Black Spirits and using songs to destroy the Dark Gate, they protect the capital.

One day, after hearing that "you" are gifted with special abilities akin to that of an oracle, you are requested to become commander of the Kagura Bukan. Concealing your insecurities, you knock on the door.

And so, the stage's curtain rises...
