The Slaughter Dungeon

Let's have an interactive story of a fastfood attendant having being Isekaid into a dungeon to be the manager (first time having a promotion), but things do have a twist, ad her dungeon becomes glitched and try to kill everything inside.

I based the idea on Bee Dungeon, but with a lot more swearing, and blood.

The skill and upgrades she will get shall be decided by the readers vote
