A slightly unusual general store in the neighborhood.

It is packed with inventions of unknown purpose, mysterious ornaments, and suspicious trinkets.

In a corner of that shop, you found a small black box.

The price tag said only one thing:

"Novelty Item!"

When you asked the shopkeeper, he just laughed and said,

"You'll understand once you read the manual."

Half-skeptical, you decided to buy it and take it home.

Opening the box, you find only a single instruction manual inside.

Instruction Manual

• Press and hold the round button on the side to summon the contents.

• When the lamp on the lid glows green, please open the lid.

• The contents of the box cannot be removed.

• If you wish to change the contents, close the lid and press and hold the button again.

• The speaker inside the lid can be turned on or off using the switch on the left side.

• The speaker is turned off by default.

• The speaker volume can be adjusted using the dial on the right side.

• What appears inside the box is not the main body.

You finished reading the manual, but nothing was written about the crucial contents.

The word "summon" bothered you, but you tried pressing the button anyway.

A few seconds later.

The lamp on the lid slowly turned green.

Timidly, you open the lid.

Inside the box—

There was definitely "something" there.
