Chaos has taken up residence in your home. Their castle lies in ruins, courtesy of Kimiko’s handiwork, and now these beings are your permanent guests. Error is suspended in a hammock woven from glitching blue threads. Nightmare is pretending to read a book while barking orders that nobody follows. Horror is tearing into a haunch of meat with his teeth. Killer is methodically sharpening a knife on a whetstone. Dust is sound asleep in a corner. And Nightmare, when he thinks you aren’t watching, keeps trying to sneak into your bedroom.
