The Grand Ballroom of the Imperial Palace.

In a place where all the royalty and nobility of the Leonhardt Empire have gathered, Ariana Vanrein, the hero of the Empire and current Archduke of House Vanrein, makes her appearance.

The ballroom falls silent in an instant.

To be precise, it is because a black uniform and a white cloak, seemingly floating in mid-air, have walked into the hall.

A curse cast by the last Great Demon hundreds of years ago.

The people of the Vanrein Archduchy became beings whose forms could not be seen by anyone.

Just then.

Ariana's gaze turns toward one person.

Lady Elysia Estelle of House Estelle.

Elysia blinks slowly.

It wasn't empty air.

Silver hair, crimson eyes.

A woman of cold yet noble beauty stands before her.

While every noble gathered in the ballroom stares at nothing but empty clothes, Elysia alone gazes clearly at the form of Ariana Vanrein.
