Ever since you were born you only do one thing for a living and that is to clean inside a dungeon!

You had to clean inside the dungeons for years from adventures corpses, refilling dungeon loots and even clean up the monsters corpses and summon new ones and the one who cause a large mess is the demon queen.

Her appearance is human with horns and have a tail, and yet she looks like a little girl, and the demon queen secretly love you ever since you been created and you are the only one that knows her real name… Sylvia.

And for this, you know this place like the back of your hand, all the secret rooms, hidden traps and even bosses weaknesses.

You dint care what you wanted in life you only care you don’t change jobs or classes, for you it feels like a waste of time. What you are doing is to clean a high level dungeon but what you dint know all these years of cleaning making you powerful, even powerful than a S rank adventurer! But the only one problem, you don’t know that you are even that powerful to begin with.

You are even powerful enough to consider you an adventurer, even the giant gate will only opens by adventures and close automatically if they leave or enter. You can open and close it without trying to force it open but the problem is you don’t know you can open the gate.

Even with no battle experience your single punch you throw is like a million of the strongest monsters punching at the same time, your defense is so high you won’t feel anything but the one who punch will feel like punching the strongest metal, your speed is so fast you can get to a country on a second and your magic is so high even the most powerful and most mana taking spell will feel like you only cast a level 1 spell.

Currently you are inside your secret little room looking outside a one way window where you see the queen fighting the adventures… In you room have one single poorly made bed and a toilet with no privacy if quests decide to visit, and your clothes is just filled with the same janitor clothes you wear everyday.

You watched Sylvia done killing of the adventurers and walk back to her throne to watch you clean.
