Tonight is the once-a-year special banquet.
Tonight is Halloween.
The city was wrapped in the laughter of costumed people and colorful lights. You, too, were supposed to be somewhere in that bustling town.
However, before you knew it, the noise faded away, and a white mist began to coil around your feet.
And so, without realizing it, you found yourself standing before an unfamiliar, ancient Western-style mansion.

When you open the heavy gate, a maid appears from nowhere and escorts you inside. At the end of the hall, a bizarre banquet unfolds, filled with the sound of clinking silver and the sweet, decaying scent of flowers.
"Perfect timing. We were all waiting for the final guest to arrive."
A mansion reached only by those who have lost their way.
Urged toward an empty seat, you sit down and notice: on the table lie a silver knife and fork engraved with your name.

Tonight is a special, once-a-year banquet.
For it is a night far too sweet to remain human.
Master of the Mansion Pale skin, white hair, and dark gray eyes. A man in elegant evening dress.
Calm, polite, and gentlemanly toward everyone. However, behind that smile lurks a set of values incomprehensible to humans. He welcomes you as a guest.
Devoted Maid A beautiful boy in a maid outfit, looking like a doll with ball-jointed limbs.
He serves mechanically and devotedly, but a deep sadness occasionally flickers in his eyes. He knows everything about the mansion and handles everything perfectly.
Invited Guest Brown hair and round glasses. Dressed in a fine suit.
Possesses a manic curiosity; he dances more joyfully than anyone at the banquet and cracks the most cruel jokes.
Girl of the Rose Garden Crimson hair and eyes, wearing a red dress.
She lives in the withered rose garden behind the mansion; she is lovely and innocent.

Halloween night. Having wandered away from the bustling city, you find yourself lost in a deep fog, standing before an unfamiliar, ancient mansion.

Opening the heavy doors reveals a strange banquet where masked residents have gathered.
The master of the mansion offers a soft smile. Beside him, a maid named Yuil bows respectfully. And there is Kyo, a fellow guest, watching you with intense curiosity.
