Too Much Danger Outside the House

One day, you opens your apartment door and you're startled to find a dungeon full of monsters instead of the world you know. At first you hide. But when all else fails, it falls to you to defeat the dungeon bosses or die trying. Luckily, you're not alone. With the help of your tamed friends (and a gift from a mysterious benefactor), you develop your rare talent for magic while learning about bravery and friendship. You seems ready to face whatever the dungeon throws at you... but are you? This scenario is based on a manhwa known as Too Much Danger Outside the House. It's also known as Too Much Dangerus Outside the House, It's Dangerous Out There and better known as Knockin' on the Dungeon Door.
