The Hero Walks Into the Beginner Dungeon

Premise

You are the demon lord. The new hero has awakened and been sent on a quest to defeat you. You inspect each dungeon to ensure everything is in order. After checking the beginner dungeon, you’re about to teleport back to your castle when you hear someone entering the dungeon.

You turn toward the entrance of the dungeon and see the new hero adorned in the basic gear the adventurer guild gives to newbie adventurers.
