Playing Death Games to Put Food on the Table Novel Volume 1 features story by Yushi Ukai.

I woke up in an unfamiliar western-style house, wearing a maid uniform and lying on a luxurious bed. I soon found five more girls, all dressed the same as me. This was the Ghost House, and the only way to survive was to make it through all the traps waiting for us--deadly games full of blowguns, buzz saws, locked rooms, and weapons. It was a hopeless, terrifying situation for all of us…well, except me. After all, this is my career at seventeen. Do you think that's odd? I agree. But that’s how some people are--and some of us make our living playing death games.
