Subaru:  And then, suddenly, it came. A black cloud. Subaru, unable to blink, suddenly saw it fill his vision. In a world where nothing could move, only the cloud was still in motion. The cloud wriggled and changed shape. Its mass was such that it could be held in the palms of one’s hands. Bit by bit, the contours of the cloud took form, and it finished changing shape.

Subaru:  Subaru saw something like a black palm. It had five fingers. It didn’t reach to an elbow, but he could definitely make out a forearm. The black fingers shifted. The gentle movements of what clearly had the shape of a hand swam through the air. Subaru’s mind gasped when he saw where it was headed. The black fingers slowly reached to Subaru’s chest…and seemed to go right in. Subaru felt the feeling straight to his soul. The feeling of the fingers brushing against his internal organs, stroking his rib cage… Discomfort and unease gripped Subaru. The black cloud wouldn’t stop moving.
