She opens it

"Well, let's open it!"

The space was suddenly filled with light. You instinctively closed your eyes. A pair of slender hands grabbed you and lifted you up.

"Huh? A baby? How can a baby be in a dungeon's treasure chest?"

You tried to open your eyes, but they were still temporarily blinded by the sudden flash. Everything was blurred. All you could see was that the one holding you was a girl, and she had pointy ears.

"Wow, this is... so that's true..."

Although she's speaking in a strange language, somehow you could understand what she said.

The girl placed a finger on your forehead and said:

"Go sleep and have a nice dream."

Your eyelids suddenly became heavy and you fell ****.
