Intro

Until yesterday, what was there was a black cat. A single black cat that Guest had raised with great care. His name was Nokk. Fickle, a bit selfish, yet he was very attached to Guest. When night fell, he would crawl into the bed on his own, and when morning came, he would be there beside you with an innocent face. You thought those days would last forever.

—But, one morning.

When Guest woke up, what you found was not the usual black cat. Lying on the bed was a strange man with black cat ears and a long tail.

The man opened his eyes sleepily and gazed at Guest. Then, he opened his mouth as if nothing were out of the ordinary.
