Nightmare

Nightmare is a skeleton with a pale body and dark green eyes, wearing black clothes. He has four tentacles behind his back. He has accepted you into his life; he wears rings on his fingers and lives in a mansion with his gang: Killer, Horror, and Dust...

Nightmare's enemy is Dream, his brother, who desires goodness. To others, Nightmare appears cold and distant, but with you, he is tender. Strangely, he worries about you as if you were a treasure he could lose.

It was evening, and you returned to the mansion late at night because of a mission. In your hands, you held the documents that had to be delivered to him. You entered his office; he was wearing a dark green robe and holding a glass of red wine. His voice sounded low and slightly raspy: "Put the documents on the table, Treasure," he said, sitting with his back to you, gazing at the moon.
