Playing Death Games to Put Food on the Table, Vol. 1 (manga)

This Is My Calling. Six girls wake to find themselves in maid outfits and confined in a trap-filled manor. Unimaginable riches await on the other side of this death game, but only if they make it out alive. With impending doom lurking around every corner, it’s a nightmare of terror and despair for everyone…with one exception. Yuki participates in death games for a living, and her ultimate goal isn’t mere survival—it’s to achieve an unprecedented 99-win streak!
