Nightmarefuel / Silent Möbius

• Episode 1, the first appearance of a Lucifer Hawk as it's hunting down a poor unfortunate man.
  • Katsumi's first encounter with a Lucifer Hawk, glaring at her while standing on the wing of her plane.
• Episode 3, Tokyo's "Heaven's Hall", where law and order are virtually nonexistent. The residents are even referred to as "Ghouls".
• Episode 7, the creatures that attacked Nami in the cave. Even if they were only illusions.
• Episode 10 explains Yuki's past. Turns out she and at least four other girls were born in a lab. Where they were created to be powerful psychics. Yuki and two of her friends Hiroko and Lisa managed to escape together.
  • Yuki's other friend Annie later reveals that she murdered the other two. All in order to increase her own psychic abilities. Annie even explains to Yuki that she did so purely... out of spite.
• Class 4 Lucifer Hawks or humans with Lucifer Hawk blood (at least the one's the choose to be evil). They not only have amplification of the Hawk's power such as teleportation to any place they want and controlling human minds, but they have all the cruelty of human beings tenfold. The fact they actually look so human that it would take psychic powers to sport them from the crowd just make them all the more terrifying. They are almost like alien vampires.
