Shibou Yuugi de Meshi wo Kuu.

Yuki wakes up in a strange mansion, wearing a maid’s outfit and lying on a bed. She soon realised there were five other girls with the same uniform and they unknowingly reached here. Now they are trapped in a ghost mansion and have to survive the deadly traps, like Saw, weapons, and even locked rooms. Everyone is scared of it except Yuki, for her playing death games is a job, and she is ready for it.
