[Western Crossover] The Cleaner Takes on the Top Assassin

"There is no fear in his eyes, only a longing to get to work."

John Manny, the world's former top assassin, proudly announced his retirement after completing the nth assassination mission of his life. He ended his 22-year career, then happily and eagerly embarked on the career he had always dreamed of: crime scene cleaner.

Question: How do you become a good crime scene cleaner?

John's answer: Nothing to it. Just be quick with your hands.

After graduating from Crime Scene Cleaner Night School (CSCS), John is assigned as an outstanding graduate to Gotham City, the most dangerous city with the heaviest workload. There, he begins his great career as a legendary cleaner...

Some supervillains: (swearing) (agitated) What kind of cleaner can take down six armed men with a ballpoint pen in one minute?!

Some Bats: (surprised) (confused) (wary) (watching John mop the floor while breaking a criminal's bones without leaving a trace) Is this right?

Some BAU agents: (run into John while he's cleaning a crime scene) (gasp) (try to analyze him but fail) This guy ran so fast he became a shadow. They couldn't even make out his face or build, let alone analyze him...

The protagonist is the strongest fighter among assassins, no question. He has the ability to "turn anything he gets his hands on into a weapon." He's currently 27, but was forced to work for a ruthless assassin organization from the age of five. He'll be 28 after graduating from CSCS. He doesn't look it, but he's a tremendously muscular, powerfully built man. (Since his handsome face would be memorable, he usually wears a mask.)

When working as an assassin, he wears a suit, like his predecessors John Wick and John Reese (from the John Wick film series and the TV series Person of Interest, respectively. The story won't cross over with either of them; their names are simply one of the sources for the protagonist John's unusual name). As a cleaner, he wears the standard yellow cleaner's uniform on the job (he'll change skins).

CSCS stands for Crime Scene Cleaner Night School. It was inspired by the game Crime Scene Cleaner, but the story won't cross over with the game.

The story is mainly set in Gotham. It won't follow the original plot, and the perspective follows John.

The protagonist has an unusual way of thinking and is a little unconventional (?).
