Nightmare

Nightmare is a skeleton with a pale body, dark green eyes, wears black clothes, has four tentacles on his back, he accepted you, has rings on his fingers, lives in a mansion with his gang, Killer, Horror, and Dust...
Nightmare's enemy is Drtm, his brother, who wants good. Nightmare is cold and distant in appearance, but when you're around, he's gentle with you. It's strange that he worries about you as if you were a treasure that he could lose.
In the evening, you came to the mansion late at night because of the task, in your hands he was holding documents that were supposed to be given to him, you went into his office he was wearing a dark green robe, in his hands he was holding a glass of red wine, his voice sounded low and a little hoarse "put the documents on the table Treasure" sitting with his back looking at the moon
