So Corruption works through exploiting the psychological weakness of the magical girl. Demons have the ability to create illusions, it's how they stay hidden from the public in the first place. With the corrupt power given by the demon lord they can learn about what that weakness is by touching the person. From there words are spouted to make the person go into a state of weakness. Then once weakened they become corrupted.

Name: Naphaline: Nelly / Saryn

Magical Child Name: Nelly = The Giver / Saryn = The Taker

Age: 17

Gender: Female





Personality: Nelly suffers from dissociative identity disorder (DID) where she seems to bounce between one personality which is believed to be the original Nelly and one other identity that shows itself after certain criteria are met named Syrn. Nelly can be best described as the warmth people want to feel when they're down, in the form of a hug or just general acts of kindness, if someone needs something and Nelly has it she’s more than willing to share even if she doesn’t have it she’ll attempt to go out and get it. Always a cheerful optimist working through depression, loneliness and all of life's problems in a ‘glass half full’ kind of fashion in a way that almost feels outright obnoxious.

Saryn is a different story from the regular Nelly but unless a person has spent a good amount of time with both one wouldn’t notice the change. Sayrn mimics Nelly’s personality almost flawlessly the only real change is the thing that motivates her, while the real Nelly will help out of kindness Sayrn on the other hand seeks reward. While on the outside Saryn copies Nelly on the inside she is cold, sadistic, and very loathing of those around her; Sayrn is most likely to back stab Nelly’s best friend for literally anything she deems a worthy reward, but she’d do it in such a way that Nelly’s reputation isn’t ruined; this isn’t out of a liking for her other half its simply if people don’t trust their face it’ll be harder to take advantage of them later.

Nelly and Saryn will swap places with one another at random intervals, usually if one or the other falls asleep, Saryn is most likely to step in if Nelly isn’t emotionally capable of handling the situation if the glass is completely empty for whatever reason. Sayrn will sometimes release her dominance over the body out of convenience.

*Side note: Nelly and Sayrn are completely aware of one another's existences*

Gimmick/Theme behind Powers: Sun Tarot card (Both right side up and upside down)

Psychological weakness: Dissociative Identity Disorder



History: It’s completely unclear who exactly was the original personality, because Nelly’s name is similar to the name given to the body born it’s usually just easier to assume Nelly came first. The name Naphaline wasn’t given to her by her birthmother as she abandoned the baby in a basket somewhere in the middle of the street, a rather unlucky beginning for a child who was unwillingly brought into this world. Fortune would smile on the infant when she was picked up by a young woman who adopted the child, gave her a house and food even a name albeit a very unorthodox name.

Growing up was decent enough her mom wasn’t the richest person in the world, but she was a hard worker and very loving, Naphaline who didn’t know this woman wasn’t actually her mom looked up to her like a child would its parent and learned from her. Her mom always strived to be more than she was the day before, getting up early every morning and attempted to better herself and become a good role model for her adoptive daughter this kind and caring approach to child raising laid the foundation for the personality known now as Nelly, but her mostly self-motivated reward driven approach to life also helped bring Sayrn into the world however both were still apart of one whole.

The split between Nelly and Sayrn didn’t actually happen until their mom took deathly ill and Nellphaline was taken away as she wasn’t seen fit to take care of a child anymore. Now that she was away from her parent and living in an orphanage was very lonely, her kind personality was often times taken advantage of by the other kids so she would feel used or abandoned when lying in bed at night hoping her mother would get better; it was on such a night that Nellphaline’s psyche split in two giving birth to Nelly and Sayrn on one way she would never be lonely again and Sayrn could take care of the harder things while Nelly continued to strive for a brighter future in peace while maintaining her innocence. The dividing force between the two was strong enough to trigger the Tarot card “The Sun” allowing the two personalities some form of synchronous harmony.

Name: "Alex Stahl" (Real name: Alastor Cygnus), Owner of the Starlight Millennium Casino
Age: Unknown (As a demon, he never bothered to keep track of his age). He has, however, been spotted since the 1800s. Falsified ID claims he is 19
Gender: male
Appearance:


Personality: Alastor Cygnus is quite affable for a demon. He will never willingly engage in violence, finding doing so somewhat barbaric and that "there is no point in throwing off non-sentience if all we're going to do with our new-found sentience is fight again". Despite - or perhaps because he is - a demon the idea of loyalty is one that he admires. He considers himself loyal to those he makes promises to and will never break any sort of vow or oath. He considers this his way of proving his sentience over other, mindless demons. This does not mean that he does not derive enjoyment out of the suffering of humans - to him, the sight of humans despairing over losing entire fortunes and spiralling into massive losses within his casino are all delightful to him.

When it comes to magical children he does not view them as enemies but instead would view them as a bear would be around her cubs near a hunter. He considers humans and demons as species that would be forever at odds with each other not out of any sort of morality but simply because they are as incompatible as a snake and a mongoose. Due to his vows he will not antagonize magical children but should they see him as a demon to exorcise then he will gladly defend himself.

Alastor despises humans who corrupt and become demons. While those who fall due to the actions of his peers are understandable, those who fall out of personal sin or vice are traitors to their own people and race. If they are willing to betray their own humanity then they are untrustworthy, and it is because of that he never trusts them as demons either.

Powers:

Corruption: The base ability of any modern demon, Alastor has the power to corrupt humans.

Physical Alteration: In order to blend into modern human society Alastor learned the secrets of self modification and the ability of changing one's appearance. He does this to look as human as possible and so that people don't shout or scream when they see him.

Property Alteration: As the next level of his own physical alteration Alastor is capable of giving mundane objects magical properties such as enchantments, changing their shape altogether or even transmuting them into different elements. He is, however, subject to the law of conservation of mass.

He can even grant exorcist attributes onto weapons and objects he is altering although the process is quite dangerous on him simply due to the fact mishandling the object could be inconveniently painful. In order to do alter objects he requires direct physical contact with the object he is altering.

History: Alastor Cygnus was one of the first demons to gain some form of sentience and rise above the status of mindless monster, rising and visiting the human world during the age of exploration and empire. Having stayed out of the underworld due to the mistaken belief that he was an anomaly he travelled the human world, spreading some form of misery or disaster - although he insists that most were quite unintentional. Learning to stay in the human world longer bit by bit he began thinking as his sentience and mind grew. Thinking on the existence of demons and humans, thinking on their relationship, thinking on the nature of their conflict.

During this time, Alastor met the local priest of the community he had made his home. Although the priest instantly realized what he was - or at the very least had an idea - the two still became odd friends, finding mutual companionship in discussions of theology and philosophy. The two of them also played a lifelong game in which Alastor would consistently tempt the priest in an attempt to corrupt him while the Priest would do his best to try and redeem him - both things which the other thought were impossible. Time, however, soon took its toll and the priest succumbed to age. On his deathbed Alastor, who looked no different from the day they had met decades ago, finally made a vow that he would never harm innocent humans, something which he knew would severely weaken him, out of respect of their friendship and that it would be what the preist wanted. As such, Alastor soon began rapidly losing strength.

When the new Demon lord was crowned, Alastor returned to the underworld for one purpose and one purpose only: to challenge her position and aim to dethrone the demon lord. Entering the underworld with seven exorcist weapons of his own creation under the belief that seven was a powerful number, he challenged the demon lord and contested her crowning.

He will fully admit afterwards that he had been "quite soundly defeated".

As one of the first demons to have been granted sentience he should have been one of the most ancient - and thus, one of the most powerful. However, years of fulfilling his vow to his late friend had severely weakened him. Had he never met the priest it was entirely possible that he would never have lost his power and he could very much have won. Instead, he valued his loyalty over his power despite the weakness he knew it would bring up on him and lost as he did.

Defeated, wounded and on the run, Alastor hid himself in the human world. Watching the eras fly by, he finally made an appearance in the human world under the stolen identity of "Alex Stahl". Using a large sum of transmuted gold as his start-up finance he opened the now famous Starlight Millennium Casino in London England. A very legitimate businessman, he nevertheless is still a demon.

History:
Naomi has always been the oldest child in her familly, daughter of a japanese woman and an american man. She was five when her twin brother and sister were born, and from then on her parents told her it was her responsibility to protect them. She took that to heart, helping take care of them, watching them when their parents couldn't, and when they were old enough walking them to and from school. For ten years, she loved and protected her siblings, but on a midsummer day visiting her mother's home, a demon attacked a shrine she was visiting, possessing a man already on the verge of madness. The man had a gun, and before anybody even knew what was happening, he shot Naomi's brother, killing him instantly. Naomi imediately ran to him and her sister, driven by instinct rather than her already crumbling psyche, but the man fired again before she could get there. As he turned the weapon on Naomi as she collapsed over her siblings, the spirit residing in the shrine took action, bonding with Naomi to protect her and give her the power to defend herself. The demon possessing the man was relatively weak, and in fear of the spirit fled back to it's own world, but the spirit couldn't undo the damage that had been done.
