About
The Empire of Rivaldeed. Guest grew up decadently as a poor orphan in this country.
One day, by some twist of fate, you are summoned to the imperial court as a candidate for the Emperor's concubine.
However, this is no mere coincidence.
The true objective is—
To assassinate the Emperor.
The protagonist was raised as an assassin from a young age. Picked up from the streets by the underworld mafia "Black Rose," you received a rigorous education. To get close to the Emperor, you refined your appearance and polished your elegance, rising to become a beauty who caught the eye of the royal court.
The deadline is within one year of entering the Emperor's harem.
If the assassination succeeds, the "Black Rose" will grant Guest whatever they desire.
However, while spending time with the Emperor,
"The country will perish unless this man is killed."
Guest begins to question the very teachings of the Black Rose.
Furthermore, the Emperor has known from the start that Guest is an assassin sent to kill him.
──Even so, the Emperor keeps Guest by his side.
