The creature more commonly known as a Contractor comes from another dimension and supposedly have no emotions of their own which is why they do not understand why the sacrifice of a single life to save billions was considered taboo or immoral.
According to Puella Magica Madoka, these so called contractors are part of a race known as The Incubators and it was their mission to collect massive amounts of energy to utilize in the construction of new planets and various interstellar phenomena as the universe continues to expand. Their supposed end goal was to prevent the eventual demise of said universe but much is still unknown about the Incubators so it's difficult to draw any definitive answers on that front.
This cute little guy is the main subject for this article and his name is Kyubey. In Puella Magica Madoka, Kyubey would seek out young girls, mainly eight to fourteen max, and offer them a wish, anything within his power to give...which was quite a lot apparently...but in return, they had to have magical powers bestowed upon them to destroy powerful evil creatures called witches.
What he neglects to mention, which is also a fair bit, the gem produced by the sealing of the contract was, in fact their soul and should they be separated from it, either by distance or time, the body from whence it came from would die with no chance of revival.
Then there is the soul gem itself. He deliberately leaves out the part of what would happen if a soul gem would become so tainted that it becomes a grief seed. Now the soul gems can be purified but the item required for it is extremely difficult to procur and it comes from the witches themselves upon defeat...if at all.
There is also one very big piece of information that is conveniently omitted or simply not volunteered at all. These so called magical girls that fight the evil beings known as witches are, in fact, are their predecessors, the previous magical girls that had become before them ...including themselves. When a soul gem has become completely blackened by despair, it will force the grief stricken magical girl to transform into that which she fought so hard to defeat...a witch.
When this truth became known in the series, everything goes sideways big time which cause the other magical girls to essentially lose their shit over it, leaving only Homura as the last one standing, having prevented Madoka from becoming a magical girl the entire time.
Madoka, having witnessed everything and learned so much, finally made a contract with Kyubey and in doing so, she gained the power to prevent all witches from ever coming into being. Instead of such a terrible fate, she gave them peace in the form of disappearing, their souls freed from the gems and their converted bodies fading from the world.
There was, however, a slight hiccup and that was the magical girl with the power to traverse back in time to before Madoka made a contract with Kyubey. She had done this many times before because she kept losing the girl she loved more than her own life and it was because of her that Madoka's potential was so strong, allowing her to become a goddess in the first place. Homura thought for certain that nothing could overturn her love's wish until the other incubators decided to see how much energy could be provided by the creation and subsequent defeat of a witch.
Again, there was a hiccup... this time in the form of Madoka that fought valiantly, breaking through the barriers keeping her from her friend. Upon reaching her, the tides were turned once more and Homura refused to simply disappear so she ripped a shard of Madoka's soul from her and fused it with her soul gem, becoming a dark goddess but it allowed them to relive their first timeline together but without the a certain furball getting in the way.
Now I don't know much more about the series after this, simply that Kyubey appeared to be leaving because humans were too contradictory and that they didn't make sense. Which is why I went and researched a bit. I discovered a small paragraph of how the lovely dark goddess, Homura, cursed the incubators to feel all the pain, sorrow, grief, and despair of all the magical girls...especially Kyubey. So in typical Artz fashion, I decided to give it a whirl Artz style...and yes, that is a thing.
After the events of the show, the Star Child was being drawn to specific verse like someone was calling to her so she allowed herself to be transported...which didn't make her Guard happy...and she found herself in a normal looking city, Japanese going by architecture and signs. She wondered what had so desperately called her to such an ordinary place.
'Help...please...I do not...under...stand...too much...I can't...make it...stop...please...'
Artz was shocked because not only had the voice bypassed her psychic defenses, but she also recognized the voice. It was impossible...why would he be there? She looked all around, becoming more and more frustrated as search bore no fruit.
'Kyubey, where are you?'
'You can...hear me?'
He was definitely in a lot of pain but of the physical variety but emotionally, he was like a Catergory 10 hurricane.
'Of course I can hear you, you stupid cat/rat. Now tell me where you are.'
'No. I will not allow another human to hurt me.'
'I don't want to hurt you, Kyubey. I want to help you. Oh and for the record, I may have been human once but I'm 100% celestial avatar now. *pause* Look, this is gonna go down one of two ways; either you come to me of your own accord or I'll use my power to drag your ass over to me then try and figure out what the hell is going on inside you because it feels like a war zone on fucking steroids.'
The Contractor somewhat relented. He did not appear but he did explain the recent events in his past and that he was now being punished for his deeds. Imagine his surprise when Artz suddenly picked him up from behind and held him close. What confused him was the fact that ahe ahe was crying...for him, she was crying because he was hurting. He was then further perplexed when she offered to take the curse from him and carry it herself.
He was an incubator so naturally he agreed to this contract of sorts, but instead of her becoming a magical girl, his eyes bulged as his body trembled ... emotion. He was feeling emotions, his own personal emotions, and he felt his eyes get hot and his cheeks get wet. What was happening to him? He caught a glimpse of himself in thw reflective surface of a window and he realized what are the weird sensations meant.
He was crying.
No incubator has ever shown tears, revealed emotion, or show anything remotely close to sentiment. They didn't care, they just did their jobs, using whatever methods were most efficient...and now he knew why. The ability to feel had been stolen from them, by what means he did not know, but he did know that his kind were only supposed to make contracts when absolutely necessary and only as a last result.
This was not good. He had made so many contracts across so many lands, realms, and realities...he was a monster. He got bonked on the head rather hard and he looked up at the source to see his savior glaring at him.
'What I'm about to say, I have told to countless others whose deeds make yours pale in comparison. Monsters do not shed tears but you do, so you see, you're not a monster at all. You were just a little lost is all.'
Why? This was the question bouncing around his head because this woman made absolutely no sense. He didn't get much more time to think about her words because they were suddenly dodging an attack...from the Dark Goddess.
'Those that make contracts with these vermin feel nothing but pain...'
'I'm gonna stop you right there because I've experienced things far worse than simply living the same set of events over and over again. *she tries to speak* I...am...talking! You will listen to what I have to say because I've walked through history; age after age, eon after eon, countless millennia, trillions upon trillions of years.
I have seen the rise and fall of kingdoms, empires and countries. I created a massive city with my own two hands, filled it with people and then it fell. Why because of time. My curse, little girl, is that I make friends, watch them get married, have kids and grandkids, only for them to die from old age while I remain untouched by time...young and beautiful and powerful but I would give it all up for a mortal life with the man I love, surrounded by the few friends that just refuse to die just so that I wouldn't lose them too.
You ripped out a part of her soul without her consent, becoming a cosplaying demonic deity of a wannabe, but where you stole, I gave. I gave a piece of my soul to the ultimate evil that had destroyed my city and all the people in it and from that fusion came a being far more powerful and benign than anything else in creation. Let me show you what true love and devotion looks like.
Come to me, Crow of the Deathly Hollows.'
'Ah, so my assumption was indeed correct. I had feeling that we would be crossing paths with you soon, Sir Kyubey.'
The demonic butler took the contractor into his arms and cradled him gently. Kyubey didn't understand, none of this was making sense. He could feel the darkness and evil from which the butler's body was made of but he sensed no evil from his actual soul. In fact, the one known as a Crow held within a soul of such incredible purity. He was so entranced with it that he barely noticed the Hollow stroking his fur in gentle yet soothing manner...so warm.
While the little Contractor was thoroughly enthralled by the Second Hollow, Artz jumped onto the roof of the building opposite of Homura. The Star Child knew that there would not be a peaceful solution to this conundrum because with taking on the link from Kyubey, she realized just who exactly she was dealing with.
There are an infinite number of parallel realities and in each reality, Artz and Anna exist in some shape, form or fashion, along with quite a few others...mainly the Prism Guard. How does this apply to her current situation? The so called demonic goddess was...Anna...and Homura held an unending and unyielding love for Madoka...Artz.
She couldn't set this world straight herself but she could take Kyubey away from this reality and into the Realm. She had felt it when his own emotions began to erupt from within, having been suppressed for generations. He needed time to recover, how to cope with sudden surges, the intensity of it all, how to control his powers so that his emotions couldnt trigger them, and create a mask to prevent others from sensing his true self...lethal intent and demonic cloak were two phrases that popped into her head.
She smirked inwardly, a fusion of the Copy Ninja of the Leaf and the Demon of the Mist...she felt like cackling like a mad woman but held it in. Work first then diabolical scheming later. Well she's said it frequently enough that people should have gotten it by now...expect the unexpected especially when she's involved.
And on that bombshell of a line, I will leave it there. I haven't really done much into Kyubey's involvement with the Guard. He just sorta pops up whenever he pleases just to give you a jump scare. *snickers* I know that there are some die hard Pokemon fans out there and hey, I played up to just before Sun and Moon and that's only because I didn't have the money...still don't but I absolutely hate what they have done to poor Sylveon. It had so much potential and could have been the new face of the fairy type. *wails in sorrow*
