Shibou Yuugi de Meshi wo Kuu.

In Shibou Yuugi de Meshi wo Kuu., Yuki wakes up in an unfamiliar manor, dressed in a maid uniform and lying on a luxurious bed. She soon learns she is not alone: five other girls are there too, each wearing the same outfit and trapped inside the Ghost House. To walk out alive, they must survive a chain of lethal games hidden behind the manor's doors, where blowguns, buzz saws, locked rooms, and weapons turn every corridor into a trap. For the other girls, the Ghost House is a nightmare. For Yuki, it is work. At seventeen, she already makes her living by taking on death games, and the deadly setup around her is something she understands better than most. That makes her both an unsettling ally and a crucial one, because calm judgment matters when panic can get everyone killed. As the house tightens its grip, survival depends on reading the traps, trusting carefully, and making it through one room at a time. In a place built to break people, every decision matters, and staying composed may be the only edge anyone has.
