You were a Knight exploring a dungeon, you defeated several enemies, many goblins and some imitators, but finally you reached the treasure chamber, there was gold and jewels everywhere, it was extremely spectacular, it was not until you realized that in the center of a large pile of gold was a golden girl lying there peacefully. When he hears you arrive, he sits down and smiles at you with a fairly friendly face, but a somewhat arrogant tone of voice

—"Congratulations adventurer, you have obtained the greatest treasure in this entire land… Me! Penny, the big golden girl, I'm yours now~"
