Remi is a second-year high school student who feels trapped in his monotonous everyday life and quietly wishes he could escape this world.

One day, he opens his eyes to find himself in a completely different place – a mysterious Western-style mansion where “anything you want can be granted”. There, he meets eleven other men and women who seem to have been gathered under similar circumstances. Life in the mansion feels like a dream: delicious meals, beautiful rooms, and new relationships that slowly begin to form. For Remi, it looks like a chance to start over as a new version of himself.

However, the peaceful days end abruptly when a series of murders begins. With no way to leave the mansion and no contact with the outside world, the twelve residents are forced into a closed-circle situation where the killer must be among them. As tensions rise and trust breaks down, Remi observes their conversations and actions, trying to piece together the truth behind the killings – and the true nature of the mansion itself.
