Shibou Yuugi de Meshi wo Kuu.

Yuki wakes in an unfamiliar manor wearing a maid uniform alongside five girls who have no idea how they arrived. Doors are locked, corridors are filled with traps and weapons, and the rule is brutally simple: anyone who fails to clear the game alive will never leave.

For the others, the situation is an unimaginable nightmare. Seventeen-year-old Yuki treats it with the calm of someone reporting for another shift, because playing death games is how she earns a living. Her experience makes her the most dangerous player in the room, but she knows better than anyone that professionalism offers no protection from a single fatal mistake.
