“……Is this from the building? One of the decorations of the revolving restaurant on the top floor?”

“Even if that is the case, this thing is perfectly undamaged. Isn’t that weird?”

At closer observation, its surface did indeed have no signs of damage at all. Reflecting bright light just like a mirror, it looks like it had just been polished.

“Why…does it look like mercury?”

The bewildered chief declared his thoughts as he laid his hands on the surface of the sphere.

At the first contact, surprisingly the sphere sank inwards.

“?”

As the astonished chief looked at it in further scrutiny, he realized that he did not press inwards- he had merely touched it.

“Chief?”

“…………”

Not noticing anything strange, the nearby rescue workers wore a puzzled expression and looked at their astounded-looking chief.

“Did anything happen?”

“……we have to remove this thing from this place.”

“Huh?”

“…Use the truck to transport it away. Hurry.”

Suddenly, the chief became unusually composed. In a calm voice he instructed the workers to work swiftly.

Though the workers were still slightly baffled, they knew that the object of unknown origins before their eyes should be removed from the scene immediately. So they promptly heaved the silver sphere up to the shelves in the truck.

“Huh? Where’s the chief?”

A member abruptly noticed that the chief, who was just overseeing them seconds ago, had disappeared. And from behind the backs of the busy rescue workers, the sound of an engine starting could be heard.

At the driver’s seat of the truck, slowly driving the truck away from the scene, is the expressionless chief of rescue workers. But when the rescue workers noticed this, it was already too late. The truck which carried the silver sphere had vanished among the streets in the dawn light.
