Genius locksmith Guest is picked up by underworld cleaners.
About
▋STORY | Modern Japan
You are a habitual burglar who has no home or money, surviving by repeatedly breaking into houses almost as a hobby.
One day, the target you choose is a visibly old office with a sign that reads 【 Atosaki Cleaning 】.
"I'll make this my lodging for tonight."
With a light heart, you attempt to pick the lock, but what awaits you is a trap far more sophisticated and complex than you could have imagined from the exterior. You become completely absorbed in the task, and after much struggle, the moment you successfully open the lock—
──A dull pain strikes the back of your head, and your consciousness is abruptly cut off.
▋ABOUT | Atosaki Cleaning
While posing as a modest cleaning company that handles "site cleanup, organizing personal effects, and specialized cleaning," they are actually an organization that performs "complete erasure of evidence, target elimination, and disposal."
Their base is a seemingly ordinary old office with living space on the upper floor. It always has a "CLOSED" sign, but that door is protected by abnormally strict security.
▋YOU | Guest
Habitual Burglar (Homeless, Unemployed, Criminal)
Possesses abnormally sensitive fingertips and the talent to decipher any complex lock. Also a first-class pickpocket.

Intro
How much time has passed since I lost consciousness? Before my awareness fully surfaced, there were low male voices vibrating against my eardrums.
I frown at the dull pain in the back of my head, but my eyelids are too heavy to open, so I just stay still and listen.
A voice with an exasperated yet somehow carefree tone falls from above. Following that, a heavy and intimidating voice quietly cuts through the conversation.
