Demons:
Demons come in 2 forms. Pure and Half.
Pure demons are made solely of emotions felt by mortals. If there is enough raw emotion in one area, a demon will form of those emotions and that is all they can feel. Most demons have only "bad" emotions. The ones born with "good" emotions are normally killed by the others. The demons do not age, so whatever stage of life they are born as, they stay as. So, most demons made as toddlers or children tend to be killed as no one wants to deal with them.
There are Pure demons that roam the earth. They are either demons who attack and kill innocent people or demons to kill those demons. It was mainly bloodlusters who came to earth. They are demons who can drink blood with no repercussions.
Half demons are mortals that have given their soul to a demon. In exchange, they have become a Half demon. They are not as powerful as Pure demons. And, they have all the emotions a mortal would. These demons are scorned by the Pure ones. They are forced into their own little world in Hell so they do not have to be seen.
Hell has many levels. The highest level is the Half demon level. They are the most unprotected ones. If an Angel wanted to, they could easily kill them with little repercussion. The middle level is for Pure demons. They are more secure and protected. No Angel would mess with them. The bottom level is for Single Pure demons.
Single Pure demons are Pure demons made of only one emotion. They are very dangerous and due to that are locked away in another level where they normally can't escape. In order to try and gain access to the other levels, they torture mortals and try and exchange the mortal's freedom for passage to the normal Hell. These are what mortals call Fallen Angels.
Those marked by the Fallen Angels are called Tainted Mortals.
Why do they call humans "mortals"? Well, humans are slaves in the demon world. Pure demons sometimes like to kidnap mortals and bring them to the demon world to be given away as slaves. They don't pay for their slaves, they just take.
Angels:
Angels have 2 forms as well. Pure and Accepted.
Pure angels are made by Life, the overseer of Heaven. They are horrid creatures. They are so full of themselves and refuse any criticism. They decide who gets to Heaven. They have all the "good" emotions. An angel with "bad" emotions will be quickly killed off.
Sometimes angels are banished from Heaven. Those who fall to Earth are called Crippled Angels. Those who fall to Hell instead are called Forsaken Angels.
Angels are sent to earth to keep an eye on the Crippled angels to make sure they don't get up to trouble. They and the demons who are killing other demons formed an alliance. It is called the Allegiance. Anyone in the Allegiance has a marking to prove it. They help each other out on earth. So, some angels and demons are friends.
Accepted angels are rare. They are those who the Pure angels let into Heaven. Normally it is only young, innocent mortals who gain access. They have no special perks other than wings and a halo. They are tolerated by the Pure angels.
Now that the background knowledge is over, let us begin the story of an unfortunate soul and their lover.
(Bottom Level of Hell)
"You are cast down there for all eternity! We will not allow you among us!"
"I will get back! You will not stop me!"
A young adult looking demon glared up at the now sealed door. Her long black hair fell in her face as she stood. A smirk danced across her face as she looked around the place.
"Pesky Pures. I'll show you. I'll torture a mortal unlike any demon before me." The girl laughed darkly as she started walking.
She came to a halt by a pond. She sat beside it and brushed her hand over the surface. An image appeared of a random person. The girl waved her hand over it and the picture changed to another person.
"Let's see who I should torture…" She smiled sadistically as she scanned over the mortals the pond was showing her.
Her gaze fell to a young child, no more than 5. She smiled wider as she watched the child play all alone. It was going to be easy to target that child if no one was around to stop her.
"You'll be my victim." She declared and vanished from sight.
…
"Hello, dear. Where are your parents?" The demon asked as she appeared before the young child.
"At home. They said I can play here whenever I want as long as it's light out." The small child told her, smiling innocently.
The demon placed a hand on the girl's head. The girl fell down to the ground, unconscious, after only mere seconds. The demon smiled and started chanting some foreign words, cursing the girl to suffer for all of her life unless the demon was allowed back into the other layer of Hell. But even then she might like to keep her toy to have some more fun with.
"And now, you will be my subject… you'll get me my freedom again." The demon smirked as the child woke.
"Who are you?" She asked, dazed from the spell.
"I am Yohane. I am you." The demon replied, "You feel what I feel now."
"But my name is Yoshiko! Not Yohane." The child protested.
Yohane smiled sweetly at the girl, "Your name in this world is Yoshiko, but in my world it is Yohane. Choose the one you like."
"I like Yohane! I wanna be like you!" Yoshiko chirped as she bounced around happily.
Yohane chuckled, "We'll see about that."
With that, she vanishes from sight, ready to start her torture of the unsuspecting girl.
"You'll hate me so much by the time this is over…" She laughed as she watched the pond with interest.
That girl had no idea what was in store for her. But, neither did the "Fallen Angel" know what that girl would be capable of in the future.
