Shibou Yuugi de Meshi wo Kuu.

When Yuuki wakes up in an unfamiliar manor wearing a maid uniform, she recognizes this as the start of a new death game. After assessing the situation, Yuuki begins to wander before discovering a room with five other maids. Each one is visibly anxious, and she learns from them that they are all new players who joined this lethal game for the prize money.

But Yuuki is different: she is a death game veteran whose only goal is to achieve 99 consecutive wins. Tasked with navigating a manor filled with countless instruments of murder, Yuuki takes point as the only experienced player in an environment that is designed to actively work against her. Despite this, she is determined to reach the end of the game with as many people as possible—if it coincides with her final goal.
