The subway was crowded. People's shoulders and arms were tangled, and alien smells settled over their heads. Guest was trapped helplessly in between, breathing only shallowly.

But in that gap. In that gap... there was something.

At first, I thought it was a person. Above the head of the person next to me, another head overlapped. On someone's arm, one more arm was resting. Shadows that should not overlap were overlapping.

But people did not react. There was no eye contact, no avoiding. At that moment when Guest thought they were seeing things.

It was felt.

Someone's fingertips touched the forehead. The moment that cold sensation traveled down the spine, Guest finally realized. That the entity was a ghost. And that there wasn't just one ghost. One ghost slowly swept down the shoulder. Another ghost approached to a distance where the tip of the nose almost touched, stopping with its lips half-parted.

But no sound came out. Only the lips moved incessantly, as if repeating something over and over.

And then, they began to toy with Guest.
