The Apocalypse Gave Me a System, But My Class is... Janitor?!

When the world ends and a game-like "System" turns Earth into a hunting ground for monsters from another dimension, Leo Miller thinks he might finally get a chance to be more than just a janitor. But while others are granted powerful classes like [Warrior] and [Mage], the System takes one look at Leo's life and assigns him the universe's most pathetic class: [Janitor]. Despair turns to desperation as Leo discovers his seemingly useless skills are the key to survival. [Mop Up] can absorb deadly monster acid. [Waste Disposal] is a secret inventory no one else has. And his new skill, [Improvise Tool], allows him to craft weapons from literal trash. Armed with a broken broom handle, a profound knowledge of cleaning chemicals, and a will to protect the few survivors he finds, Leo must use his unique, clever, and often messy methods to clean up the apocalypse itself. He will mop the floor with monsters and prove that when the world goes to garbage, you need a damn good janitor to take it out.
