One was pitch black. Even from close up, Kamijou could not tell what it was. It looked like an octopus floating in the deep sea, like a soft piece of fat cut away with a knife, or like a loose rubber film being melted from the inside. The more he stared at it, the more its meaning changed and the more confused he became. The surface was covered in ominous bubbles and some things that were not quite eyeballs and not quite suckers blinked with a damp yellow or green light that resembled glow-in-the-dark paint. It almost looked like the colors of a strange poisonous frog or lizard.
