Terminology / Demon Ranks

 * The Underworld - A place where the souls of the all recently departed go, an Afterlife or Realm of the Dead located below the realm of the living. Exact conditions of the dead vary depending of the pantheon, but every soul comes there and while some may be punished and others rewarded, for the most the Underworld is a place of waiting and either rest or boredom.
 * Rank A: Nether Demon - They are often both the most powerful and ancient demons, in some ways closer to sentient concepts than anything else. Their bodies are mostly made from nether, the essence that flows through the realms of the living and the dead.
 * Rank B: Archdemon - A demonic creature of unimaginable power. They have innumerable powers that are beyond the comprehension of that of lesser demonic beings and are able to rule over an entire pantheon as their god out of both power and fear with very few beings capable of opposing them.
 * Rank C: Succubus - They possess incredible supernatural power, unchallenged dominion over demons of lust and corruption, and tremendous supernatural abilities in both domains.
 * Rand D: Hellhound - A supernatural canine connected to the Underworld. Features that have been attributed to hellhounds include black fur, scales, glowing red or sometimes yellow eyes, super strength and speed, ghostly or phantom characteristics, foul odor, and sometimes even the ability to speak. They are often assigned to guard the entrances to the world of the dead, such as graveyards and burial grounds, or may undertake other duties related to the afterlife or the supernatural, such as hunting lost souls or guarding a supernatural treasure.
 * Rank E: Imp - A small lesser demon, often shown as small and not very attractive creatures. Their behavior is described as being wild and uncontrollable, with a sense of free spirit and enjoyment of all things fun. Most of the time, the pranks were harmless fun, but some could be upsetting and harmful, such as switching babies or leading travelers astray in places with which they were not familiar. They are often willing to bind themselves to magic-users as familiars, serving as spies and informants using their ability to take animal forms. They have some abilities relating to fire and are hard to kill, possibly to the point of being immortal.

Characters

 * Crystal Hollow - A 19-year-old woman who was a very kind and gentle girl with dreams of becoming an artist. After being betrayed, imprisoned, drugged, tortured, beaten and raped by several people who manipulated her, Crystal's kind personality changed completely to that of a woman vindictive, cruel, brutal, unstable, psychopathic, relentless, bloody and sadistic. She completely discarded almost all of her old, kind and generous personality in order to become a sadistic, violent and cold-blooded killer so that she could have her revenge. After meeting Jigoku, Crystal was able to acquire power from demonic forces and uses those abilities for her own good. While using him as a source, she started to care about Jigoku and falling in love with him.
