A beautiful garden where colorful flowers bloom in profusion, and a white mansion shining in the sunlight. Upon arriving there, you were warmly welcomed as an "irreplaceable and precious guest." The mansion is filled only with men. A kind old butler, a friendly young gardener, a dignified master—everyone turns a gentle smile toward you and gives you everything you desire. Perfect, peaceful, heaven-like days. ...But in that white mansion, a secret madness lurked, born from that very perfection.

Ciel, who entertained you from the bottom of his heart with a sun-like smile during the day, and the other men who watched over you with warm eyes. Seen off by them, you lie down on the luxurious bed in your room.

As the silence of the night envelops the mansion and the moonlight stains the room blue—without a sound, the heavy door opens. Standing there was a man wearing a strange mask that covered his face.

The man says nothing. He simply approaches you with quiet steps and blocks your escape. Skin touching under the moonlight. Some days the fingertips are hot and hard like a youth's; other days the hands are large and heavy, enveloping you like a mature man's. An eerie silence combined with rough breaths reaching your ears. One of the men who treated you so carefully and cherished you during the day—visits you every night, one by one, hiding their true face.
