Chapter 1: The boy and the Demoness
-Age: 2-
It's been a year since Lilith had taken Hadrian from his home dimension and brought the little Potter to Earthland.
And If Lilith were to be honest. She enjoyed the baby boy's company. Aside from changing his diapers, the little boy was a joy to be around, he drank milk directly from Lilith's breast who enjoyed the experience, but at moments for a split second, Lilith noticed the flicker of blue flames around Hadrian's body.
Smiling to herself, Lilith would spend days at a time, being around the baby boy, watching him as he crawled around with a silly smile on his face, the heat of the nearby volcano no longer bothering him.
Good, his body is processing the Slayer Magic within him Lilith thought to herself as she sat on the couch, enjoying the baby's babbling.
-Age: 3-
Already Hadrian was starting to bring forth his Magic in the form of blue fire, something that made Lilith proud to no end.
With the signs of his Devil Slayer Magic beginning to grow, Lilith watched as the little Potter waddled around, struggling to stand on his two feet as he used nearby objects to help himself stay upright.
Smiling at the babbling baby, Lilith bent down and picked him up by the armpits, bringing him up to her breasts where the little Potter laid his head on.
Giggling at her future mate's action, Lilith moved towards a nearby window and looked out, watching the volcano as it continued to give off heat, occasional spots of lava shooting out of the volcano and sliding down the side.
Looking down, Lilith noted the awed look on Hadrian's face as he stared at the lava that slid down the side of the volcano.
"That's lava, it comes out of the volcano" Lilith says, kissing Hadrian on the forehead.
Looking up at the only person he knew, Hadrian babbled as he placed his hands on top of Lilith's breasts.
"Bava" The Little Potter spoke, causing Lilith to coo and smash her breasts into Hadrian's face.
"Oh you said Lava. That is so adorable" Lilith gushed as she hugged Hadrian tightly.
Giggling at Lilith, Hadrian smiled as his entire body was soon engulfed in bright blue flames.
Squeaking in surprise, Lilith stood up and made sure that Hadrian wouldn't burn anything inside the house.
"Hey, be careful! The walls and the house may be fireproof but it doesn't mean that the inside is!" Lilith exclaimed.
Looking up at Lilith, Hadrian's lip began to tremble as tears began to form in the corner of his eyes.
Realising that she had scared her mate, Lilith pulled the young Potter into a hug as she stroked his hair, causing Hadrian to rest his head on her.
"Don't worry, I am not angry at you. But you should know to be careful when you use your Magic, ok?" Lilith asks, looking down at Hadrian.
Nodding his head, the little Potter held tightly onto the Demoness, enjoying the softness of her breast.
Chuckling at the little boy's attachment to her breasts, Lilith held Hadrian as she sat back down, watching as lava slid down the Volcano.
-Age: 4-
Narrowing his eyes, Hadrian growled as arm was engulfed in bright blue flames. Standing outside his home, Hadrian took a deep breath as he stood before a large boulder that had broken off from the volcano and tumbled down near their house.
"Hellfire Demon: Destruction Fist" Hadrian roared, smashing his fist into the boulder.
Boom
The boulder explodes from the impact, remains of the boulder flying everywhere as Hadrian remains frozen, breathing heavily with his arm out.
"Very impressive" A voice calls out, eliciting a smile from Hadrian.
Turning around, the young Potter's eyes soften when he sees Lilith standing before him, currently in a bathrobe that showed off a dangerous amount of cleavage.
"What can I say, I try to impress," Hadrian says, spreading his arms out.
Giggling into her hand, Lilith smiled as she walked towards the young Potter.
"That may be, but while you have power and the Magic required, you must also learn the many spells that you will one day need to fight and you know what that requires" Lilith says with a knowing smile.
Groaning in frustration, Hadrian kicks a small bit of the remains of the boulder in frustration.
"…Study" Hadrian says in annoyance.
In response, Lilith merely giggles.
-Break-
"Do you understand now?" Lilith asks as she stands before Hadrian who was currently in his seat with a desk in front of him and a notebook and pen on the desk.
The young Potter looked up at Lilith with a blank expression on his face.
"…No" Hadrian answers.
Sighing slightly, Lilith rubs her forehead and takes a deep breath.
"Alright, simply put there are two different types of Devil Slayer Magic. The most common and well known type is in fact the weakest. Commonly known for its black markings, this type of Devil Slayer Magic is the result of those using the Curse of Etherious… I hope you know what the Etherious are" Lilith asks with a raised eyebrow.
"The Etherious are Demons created by the Dark Wizard, Zeref… These Demons are known to the Demons of Purgatory such as yourself as the-""Fake Demons" Lilith says, cutting Hadrian's explanation off.
"Yes… The Etherious are known as the Fake Demons as they are made by a Human. The Curse the Etherious uses is weak compared to the Curse we Demons use, as a result the Devil Slayer Magic from the Curse of the Etherious is far weaker and limited compared to the other type… In fact the Etherious Devil Slayers are just knock off Dragon Slayers as they also eat their element which you cannot do" Lilith admitted, scratching her chin in thought.
"Anyway. Now there is the more powerful type of Devil Slayer Magic. This is the one you use. The Demons of Purgatory would know you as a True Devil Slayer as not only do you use our Curse but you also gain a Demon Form. While the Etherious Devil Slayer can also gain a Demon Form, the use of their Curse will in fact make the wielder go insane, making them rash and causing them to create poor decisions. One thing about True Devil Slayers is that they are the rarest of the three Slayers, due to this not much is known about them, except of course God Slayers trained by Gods and Dragon Slayers trained by Dragons follow traditions that all Slayers follow" Lilith explained.
"Traditions?" Hadrian asks, confused.
Smiling at the young boy, Lilith began to place books on Hadrian's desk.
"One thing about all Slayers that they have in common is Mate Markings. Mate Marking is where a Slayer marks their mate for all Slayers to know, as a result all Slayers and even Demons, Gods and Dragons know to stay away, or at least not pursue that Mate romantically, of course their are the rare exceptions where the Slayer has multiple Mates, but anyway the only Slayers that can't have Mate Marking are the Etherious Devil Slayers due to their curse affecting their mentality and behaviour" Lilith answers calmly.
"As a result many Etherious Devil Slayers became ineffective after a certain period of time… Of course this was before the Etherious wiped them out in fear of their power"
"So besides the power, what other differences are there between Etherious Devil Slayers and my type?" Hadrian asks curious
"The difference between Etherious Devil Slayers and True Devil Slayers is that like a Demon of Purgatory, you will grow stronger just by being around your element, which means that any fire Magic directed at you will in fact strengthen you, unlike Dragon Slayers you will not need to eat your element… Another thing is that unlike Etherious Devil Slayers your senses will be enhanced" Lilith answers.
Blinking in surprise, Hadrian leans forward, interested in what he could gain.
"Like what?" Hadrian asks curious.
Smiling down at her future Mate, Lilith bends down towards Hadrian, giving the young Potter a perfect view of her cleavage.
"One interesting fact about Slayers is that they gain properties of the creatures they kill. For their senses, Dragon Slayers senses such as Smell, Hearing, Sight, taste and touch are dialled up to 11. For God Slayers they gain the ability to sense the use of their element within a certain vicinity and those in their element, this in turn makes it basically impossible for someone of the same element or in their element to sneak up on the God Slayer; Due to that they are just as dangerous as Devil and Dragon Slayers. And for True Devil Slayers, they gain the ability to sense the Magical energy of everyone within their vicinity, making it nearly impossible to sneak up on them and it allows you to sense any Demonic blood or energy within a person which in turn allows you to sense what type of Magic the individual uses as it is connected to their Magical Energy. No Demon will be able to trick you through disguises" Lilith smiles coyly at the young Potter.
Without another word, Lilith straightens up and pats Hadrian on the head, momentarily freezing as she feels a bump on his head.
-Age: 5-
"Hey Lilith?" Hadrian turns towards the woman who had raised him, looking up at her with a questioning gaze.
Now 5 years old, Hadrian had small black horns protruding from his head, his sclera had gained black cracks that had slowly begun to grow over time, slowly consuming the white of his eyes.
"Yes, Hadrian?" Lilith asks, looking down at the young Potter.
Currently located in a village, both Hadrian and Lilith looked around, with Lilith in her Human form.
With the majority of men drooling over Lilith's figure and the jealous glares from the women, nobody really noticed the small horns and the eyes of the young True Devil Slayer.
"Are we like them?" Hadrian asks, pointing to a couple holding their child as they sat near a river, smiling as the child splashed around, laughing happily.
Smiling down at the young boy, Lilith shook her head.
"Not exactly. We are more like that man and woman" The Demoness answers, gesturing to the parents who held each other as they watched.
Tilting his head, Hadrian felt confused as to how he and Lilith were like the man and woman.
"Why them?" Hadrian asks curious.
"Because one day we will have a child of our own. Don't you want to be a daddy?" Lilith asks as she lifts Hadrian up into her arms.
This caused the young boy to pause, a daddy? He had never thought about having one let alone being one.
"I-I don't know" Hadrian answers, frowning slightly.
Smiling at her future Mate, Lilith kisses Hadrian on the forehead and the both of them soon leave the village, returning home near the active volcano.
-Back on Earth-
"WHAT DO YOU MEAN MY SON WAS KIDNAPPED!" the voice of Lily Potter echoed through the halls of Hogwarts.
Currently located in the Headmaster's office, Albus Dumbledore let out a tired sigh as he looked at the couple before him, with two small babies in their arms.
Born only a few minutes apart with red hair, the Potter couple gave birth to twins, Violet Potter and Alex Potter, both. twins had the same hair as their mother but Alex has hazel brown eyes and Violet has emerald green.
Immediately after the wards lost its power, the Potter couple immediately left to go see Dumbledore to retrieve their son, only for the news of his kidnapping to reach their eyes.
"It is as I said. After you both went into hiding I intended for Hadrian to be placed with Sirius… The only problem was that Sirius was illegally imprisoned by Barty Crouch Senior who sent Sirius straight to Azkaban without a trial. After that I had planned to place Hadrian with the Longbottoms only for hoth Alice and Frank to be tortured to insanity, resulting in young Neville to be placed with his grandmother" Albus answers, looking down in shame at failing both parents.
"Then how was Hadrian, our son, Alex and Violet's older brother, kidnapped?" James asks with a worried expression on his face.
Sighing slightly, Albus pulled out his wand and placed the tip at the side of his head. Closing his eyes in concentration, Albus slowly moved the wand away as pulled a glowing string from his head.
Realising what was going on, Both Lily and James walk towards the pensive as Albus places the string into the bowl.
"I am truly sorry. I had tried my best to locate young Harry to no avail, I hope you can forgive me" Albus says just as both Lily and James enter the pensive, both Alex and Violet sitting on their parents' chair as they look around with child-like curiosity.
-Back in Earthland-
"Hellfire Demon: Devastation Talon" Hadrian roared as he slammed his leg into an incoming boulder that had been launched from the volcano.
Quickly jumped to the side, Hadrian snarled as he brought his fist back as another boulder was falling towards him.
"Hellfire Demon: Destruction Fist" Hadrian screamed as he punched the boulder, destroying it on impact.
Taking a deep breath, Hadrian looked up at the volcano, glaring at it with anger.
This is starting to get annoying, The young Devil Slayer thought to himself.
"Demon Slayer Secret Arts: Annihilation Surge" Hadrian yelled as bright blue flames engulfed both of Hadrian's arms, bringing both arms to his chest, Hadrian swung them outwards in a single motion, sending a wave of fire, consuming all the boulders falling down.
As the flames began to dissipate, Hadrian let out a breath as he fell to his knees, tired from the large use of Magic.
Tilting his head slightly, Hadrian was able to somewhat sense a familiar Demonic Energy making its way towards him.
"I must say I am impressed with your progress, you are able to use the Secret Arts despite the already large amount of spells out had been used" Lilith says with an impressed tone.
Chuckling slightly, Hadrian attempted to stand up, only for his legs to lose strength and fall down, into the arms of Lilith who had caught him.
"I strive to impress" The young Potter mumbled as his eyes slowly began to close, exhausted from his large use of magic.
(A.N: I am going to make one thing clear, Magic and Curse may be two different things as Magic is not as dark or evil as Curse, but I will still call Curse, Magic as it is just a darker version of Magic, just powered by dark emotions and it keeps things simple.)
-Age: 6-
Letting out a pained yell, Hadrian felt his arm break as he landed on it with a loud crack.
Standing above the young boy, Lilith looked down at the young Potter, arms crossed.
"I know you can do better than that. Get up" Lilith ordered with a blank expression on her face.
Growling in anger, Hadrian opened his eyes revealing glowing emerald green eyes, the sclera of his eyes now fully black, consumed by the cracks that were once visible in the white of his eyes.
Slowly getting up to his feet, Hadrian felt his arm surge with pain, causing him to let out a pained yell.
Sighing to herself, Lilith shook her head and waited, knowing that he needed a few moments.
Slowly but surely, Hadrian felt his Demonic Regeneration kick in, slowly healing his broken bone.
"That's one of the things we Demons have over the Gods and Dragons, we have better healing." Lilith says with a smug grin. "But do not forget that healing requires Magic, that means you are not invincible" The Demoness warns with narrowed eyes.
Taking a deep breath, Hadrian nodded his head and looked up at Lilith with a determined gaze.
With black horns protruding from his head that could be grasped by both hands, Hadrian cracked his neck and bent his knees slightly, ready to lunge at the Demoness.
Moments passed and Hadrian charged at Lilith, dark blue fire engulfing his arm as he swung forward.
"Hellfire Demon: Destruction Fist" Hadrian roared as he striked, hitting Lilith in the face.
A few moments passed and the young Devil Slayer blinked. She had not moved an inch, completely unaffected by his attack.
Chuckling to herself, Lilith grabbed Hadrian's wrist and twisted.
CRACK
Letting out a scream of pain, Hadrian watched as dark purple flames covered Lilith's fist as she pulled her arm back.
"This is how you do it Hellfire Demon: Destruction Fist" Lilith yelled out, striking Hadrian in the gut, sending the young Potter flying back.
Landing on the stone, Hadrian gasped as he coughed up blood, his vision blurry as he began to focus his Magic on healing the damage that Lilith had done.
With what seemed to be hours but was mere minutes, the pain that consumed Hadrian's entire being slowly began to fade with only exhaustion and soreness replacing it.
"I'm impressed. That type of healing should have knocked you out and yet here you are, awake… If only barely" Lilith says, walking towards Hadrian.
Breathing heavily, Hadrian wobbled as his vision began to blur, a headache beginning to form as he struggled to stand on his own two legs.
As his strength began to leave him, Lilith moved forward, catching the young Potter just as his legs lost the strength to carry him.
"Rest my love. You have done well" Lilith whispered into Hadrian's ear as his eyes slowly began to close and he fell into the warm embrace of sleep.
-Break-
Slowly opening his eyes, Hadrian let out a yawn as he attempted to sit up, only for a pair of arms to stop him from moving any further.
Chuckling slightly, Hadrian looked up to see the sleeping form of Lilith, nude and pressing her soft warm body against his equally naked body.
Relaxing in the Demoness' embrace, Hadrian wrapped his arm around Lilith's waist and pulled her closer to him.
Feeling Lilith's large breasts press against his chest, Hadrian looked at Lilith's sleeping face.
The Demoness was beautiful but when asleep she seemed radiant, something out of a dream.
As Hadrian continued to look at the woman who cared for him for nearly all of his life, Hadrian paused as he felt something off.
Pulling his arm back, Hadrian blinked as he looked down at his hand, which had begun to change as the end of his fingers began to show signs of claws, the end of his fingers becoming pointed as they lengthened slightly.
Huh, didn't know I would get claws, The young Potter thought to himself in surprise as he turned his hand around, inspecting the change.
Knowing that he would get to spend time to test the results of his continued transformation, Hadrian placed his arm back around the Demoness' waist, relaxing into her embrace once more.
-Age: 7-
Taking a deep breath, Hadrian wiped his forehead, removing the sweat that drenched his face.
Currently in the middle of a forest, far from his home and the heat of the volcano, Hadrian felt weakened as he no longer had the power boost from the increased heat and distance towards a large fire source.
Not too far from the young Devil Slayer, Lilith watched with a smile as Hadrian dropped down and began to perform push ups counting every time he performed a pushup.
It seems I was right with keeping Harry near that volcano during his first years in training Lilith thought to herself, recalling how the continuous absorption of Magic due to the vicinity of a large fire source resulted in a larger Magical Container for the young boy while also resulting in excess Magic being pushed throughout his body, further enhancing his strength and physical abilities.
And now she stood, watching as Hadrian trained without the boost of his element being nearby, weakening the young boy as a result.
But certainly not weak The Demoness thought to herself, looking at the muscles that had begun to form on Hadrian's torso and arms, a result of gaining large amounts of Magic constantly.
Looking closely at the young boy, Lilith noted the change in Hadrian ever since he became a Devil Slayer.
The first and most notable one was his black horns that protrude from his head.
The second was his eyes, no longer white, the sclera of the boy's eyes was pitch black, leaving only his pupils and iris unaffected even if it's a little more prominent as a result.
The next was claws that the young Devil Slayer grew, replacing his fingers with sharp pointed claws, his entire hand gaining a darker skin tone as a dark bone-like plating formed over it.
The last noticeable change was the young Potter's feet which had begun to change, forming into dark talons with the same bone-like plating forming over Hadrian's feet.
Smiling at the young boy, Lilith noticed that the young Devil Slayer's skin had gained a greyer skin tone, something that was hardly noticeable until you looked closely.
I wonder what the end of his transformation is going to look like Lilith wondered.
While this was happening Hadrian turned around, rolling onto his back and began to perform sit ups, unaware of the lustful eyes of Lilith.
-Age: 9-
Two years had passed and Hadrian found himself standing on top of the volcano, looking down at the place he called home.
The young baby boy that was once brought here as a Human, the young Devil Slayer was no in his Demon Form, with dark grey skin with dark bone like plates over his body, 5 large clawed talons that were once his feet and sharp claws.
With a deep breath, Hadrian bent his legs and jumped off the edge of the volcano, jumping down the side of the volcano towards his home of 8 years.
As the young Devil Slayer got closer, he noticed a man standing beside Lilith, he had tanned skin and black hair with horns protruding from his head and a tail swinging behind him.
Blinking in surprise, Hadrian landed before the two, cracking the ground slightly from the impact.
"Ah hello Hadrian, good to see you are here" The man says with a smile. This man is Lucifer, twin brother of Lilith and a man who helped train Hadrian when he had truly begun his training.
"Lucifer, how are you today?" Hadrian asks with a raised eyebrow.
Chuckling slightly, Lucifer turned to Lilith with a smile, silently asking her to answer.
"I asked Luci here to bring you a present for your birthday" Lilith answers with a bright smile.
Cocking an eyebrow, Hadrian looks at Lucifer who was shaking his head with a smile, amused by Lilith's giddiness.
Without a word, Lucifer brought his hand out and in a flash of hot white fire a sheathed sword emerged.
"This is Armageddon, this is the blade I used in my youth, and now, it belongs to you" Lucifer says with a smile, handing the sword to Hadrian who stared at the blade with a gaping mouth, showing his sharp teeth.
"T-Thank you" The young Devil Slayer stuttered in shock.
Lilith smiled brightly at her brother and her future mate's relationship.
They get along so well Lilith thought to herself happily.
-Back on Earth-
Within Potter Mansion, Lily Potter could be seen in her room, crying as she held a picture tightly in her hands.
This picture was of the last she had seen her eldest son.
With Hadrian in her arms as he babbled happily, right before the Potter couple went behind the wards to protect them.
I wish we had never hidden under those stupid wards Lily cursed internally as she continued to cry.
"Mommy?" A small voice hesitantly called, shaking Lily lightly.
Quickly realising who was here, Lily wiped the tears from her eyes and sat up, looking down at her son who stood at the side of the bed, worry in his hazel brown eyes.
Now 5 and a half years old, Alex had spent all of his life, seeing his mother in her room, crying with a picture in her hands. A picture of his eldest brother, Hadrian. Or as he is known in the Wizarding World, The-Boy-Who-Lived.
"Yes Alex, is something wrong?" Lily asks, trying to hide the tear marks on her face but was unable to hide her red eyes.
Sighing slightly, Alex offered his hand with a soft smile on his face.
"Come Mommy, Violet wants to go to the pool" Alex says, internally hoping his mother would accept so she would be able to at least be distracted by the fact that her eldest son was missing.
With a sad smile on her face, Lily nodded her head and took Alex's hand, getting up from the bed and allowing him to lead her to the backyard where James and Violet were.
Seeing his wife, James smiled softly at her and made his way to her.
Giving the beautiful redhead a hug, James whispered softly into her ear, allowing Lily to relax in his embrace.
"We will find him. I promise" James promised.
As the Potter twins watched their parents hug, Alex turned his head slightly to look at his twin.
"Any luck?" Alex asks hopeful.
Shaking her head with a sigh, Violet slumps forward.
"Nothing, I looked in the library but I couldn't find anything. Truthfully I couldn't even understand half of it" Violet grumbles.
Alex sighed, knowing that finding their brother would be nearly impossible, if he was alive that is.
I'm sorry Mum, Dad. We failed you Both twins thought to themselves with their heads down in shame.
-Break-
Snap, Snap, Snap
Hadrian let out a sigh as he sat at the front yard, a ball of light blue fire above his claws before it was extinguished with a snap of his claws.
Snap
The light blue fire forms above the young Devil Slayers claws once more.
Snap
Snapping his claws once more, extinguishing the flames, Hadrian stared at the volcano in the distance, patiently waiting for Lilith to arrive.
"Hope you weren't waiting long" Lilith says as she sat beside the young Devil Slayer.
Shaking his head, Hadrian turned towards Lilith with a blank expression on his face.
"No, so what did you want me out here for?" Hadrian asked curious as he extinguished the flames with a snap of his claws.
"It's about Armageddon. I want to use it to create a seal for you" Lilith states.
Frowning, Hadrian turns to the Demoness, tilting his head slightly .
"And why do you want to create a seal?" Hadrian asks cautiously
Letting out a sigh, Lilith placed her hands together on her lap.
"The reason is that due to your age you aren't able to go back and forth between your Human Form and your Demon Form, now this isn't your fault. In fact it was pretty common for True Devil Slayers, this is due to your growing powers and strength. The reason for this is because True Devil Slayers, in terms of raw power, are the weakest of the 3 Slayer types... But as a result Devil Slayers have easy access to their Demon Forms, gaining it at an incredibly young age and being able to maintain it indefinitely, boosting their power to close the gap in power between the 3 Slayers Types. If there are any 1st generation Slayers then it is incredibly unlikely that they will be up to your level of power as I made sure you trained like a Devil Slayer back in the day would. In fact for your age you are certainly more powerful than the Devil Slayers when they were your age" Lilith states.
Cocking an eyebrow at that, Hadrian thought it over and hesitantly noded.
"Fine, I will let you create a seal. But how would I be able to access my full power afterwards?" Hadrian couldn't help but ask.
Lilith giggles and smiles down at the young Devil Slayer with amusement in her eyes.
"Oh that is simple, just unite the sword with yourself" Lilith answers.
Blinking in surprise, Hadrian turned to the Demoness with confusion present on his face.
"And how am I supposed to do that?" Hadrian asks, cocking an eyebrow.
"Oh that's simple… Stab yourself" Lilith answers.
Pause. The young Devil Slayer stared at Lilith… Then blinked.
Standing up, Hadrian grasped Lilith's head and began checking her over.
"Hang on there a second Lils, I think you might have a couple of loose marbles in there" Hadrian says as he turns Lilith's head to look at the back.
"I do not!" Lilith whined, swinging her arms around, tears in the corner of her eyes.
-Break-
"How did this happen?" Hadrian thought out loud as he sat on the ground, tied up with rope.
Standing in front of Hadrian was Lilith, pouting at him with her cheeks puffed up.
"So are you going to create the seal or not?" Hadrian asks with a raised eyebrow.
Lilith narrowed her eyes at the young Devil Slayer, her cheeks puffing up more.
The young Potter sighed and shook his head, knowing exactly what the Demoness wanted.
"I am sorry Lilith. That was mean of me" Hadrian apologises.
Lilith looks at the young Potter for a few moments, then smiles brightly at Hadrian, happy that the Devil Slayer apologised.
"Now let me fucking go" Hadrian orders.
Lilith the pouting Demon returns.
-Break-
"Alright, ready?" Lilith asks, holding Armageddon in her hands.
Nodding his head in response, Hadrian took a deep breath and growled, his body soon engulfed in dark blue flames.
Taking in a deep breath, Lilith placed the blade of the sword into the ground, the handle pointed upwards.
"Talu Markato, Unra salook, Ta raso. Mingu sanu milorock" Lilith began chanting in Demonic Tongue as slowly Hadrian watched his flames being absorbed into Armageddon. Slowly the sword's blade began to shift to dark blue, dark runes being formed in the centre of the blade as it continued to absorb Hadrian's Demonic power, sealing it within both the blade and within the young Devil Slayer.
With a few final words, Lilith gestured to Hadrian and nodded her head to the sword.
Understanding what she wanted, Hadrian grasped the handle of the sword and hissed as his horns began to recede, along with his claws and talons, his skin regaining its original colour and the bone-like scales beginning to recede.
As the transformation came to an end, Hadrian let out a shuddering sigh as he fell to his knees, drained from the sealing of his power.
Now with slightly tanned skin, Hadrian's sclera was now white, his head lacked the horns that were once there and his talons were now replaced with feat, the young Devil Slayer appeared Human.
"It is done," Lilith says as she smiles at Hadrian.
-Age: 10-
Just a bit… Further Hadrian growled as his body was drenched in sweat as a pair of chairs was wrapped around his arms.
Attached to those were two large boulders, dragged across the ground as they created massive lines in the dirt with every step Hadrian took.
Feeling his body break only for his Demonic healing to repair the damage, Hadrian felt his entire body protest his movements as his muscles were torn and healed within seconds.
The more the young Devil Slayer healed, the more Magic was being consumed to allow Hadrian's healing factor to work.
After the last two steps, Hadrian let out a gasp as he fell to his knees as the chains magically released their hold on him.
"Are *gasp* you *gasp* happy now? *gasp*" Hadrian asked as he struggled to breath, nearly wheezing with every breath.
From the trees, Lucifer emerged with a smile on his face.
"I am indeed impressed, Harry. Now come on, I'll take you to Lilith. I am certain she would like to help you rest" Lucifer says with a slight chuckle.
"Yeah fuck you too" Hadrian cursed the Demon, only receiving a laugh from the Demon in response.
Without a word, Lucifer bent down and picked Hadrian up, throwing the young Devil Slayer over his shoulder like a sack of potatoes.
"Oh you are a fucking dick" Hadrian cursed as he winced at the surge of pain from having Lucifer's shoulder press into his stomach.
Letting out another amused laugh, Lucifer walked towards his sister's home occasionally chuckling at Hadrian's curses, knowing that the young boy would be back to normal after he recovered.
-Break-
Letting out a content sigh, Hadrian laid in the hot bath, the water soothing his sore muscles as he closed his eyes.
"Hey no falling asleep on me young man" A voice states, eliciting a chuckle from the young Devil Slayer.
Opening his eyes, Hadrian looks up to see the amused face of Lilith who was also in the bath, her arms wrapped around his torso as he laid against her.
"Why not? Your boobs are incredibly soft and firm" Hadrian asks with a raised eyebrow.
Giggling at her future mate's bluntness, Lilith leaned her head down and placed her lips against Hadrian's, her tongue entering his mouth, swirling around his tongue.
Battling against the Demoness' tongue for dominance, Hadrian let out a small moan as Lilith wrapped her hand around his dick, softly stroking it as they kissed.
Lust burned in Lilith's eyes as she felt Hadrian grow in her hand.
With a smile, Lilith moved her head away from Hadrian's, leaving a strand of saliva attached to their tongues before it soon broke apart from the force of gravity.
"You've grown. Looks like it's time" Lilith says with a hint of excitement.
Looking up at the beautiful Demoness, Hadrian grinned as he knew what the black haired beauty was referring to, excitement shining in his eyes.
"Then let's have a little fun" Hadrian smirks, causing Lilith to bite her lip at his handsome and cute face.
"Yes… Lets" Lilith responds as she kisses the young Devil Slayer once more.
-Time Skip-
A groan escaped Hadrian as his eyes opened, the sun shining in his eyes, temporarily blinding the young Devil Slayer.
Looking around, the young Potter blinked as he noticed that Lilith was not in bed with him.
For the young Devil Slayer it was an unusual event and so, throwing off his covers and revealing his nude form, Hadrian grabbed his underwear and some pants and went downstairs, to see Lilith sitting in the dining room.
"Morning Lilith, what are you doing up so early?" Hadrian asks with a frown.
A sad sigh escaped Lilith as she looked up at Hadrian.
Eyes widening, Hadrian realised that there was only one thing in this scenario that would make the Demoness upset.
"It's already begun hasn't it?" Hadrian asks with a small frown.
Nodding her head, Lilith stood up from her chair and made her way towards Hadrian, wrapping her arms around the young Devil Slayer.
"Yes… A rebellion has begun in Purgatory and I need to stop it, along with Lucifer" Lilith informs Hadrian, causing a sigh to escape the young Potter.
"How long?" Hadrian asks with a worried expression.
"I don't know" Lilith answers honestly.
Clenching his fists, bright blue flames engulfed Hadrian's arms, signifying its weakened form due to the sealing of his Demon Form.
A hand touched Hadrian's chin, softly pushing his head up to Lilith's sad yet smiling face.
"I will be back. I promise you" Lilith whispers as she places her lips on Hadrian's.
Pulling the Demoness into a tight hug as their kiss became more intimate, soon Hadrian felt Lilith eventually pull away from his arms.
"I need to go. I will visit when I have the time and when the rebellion is over we can be together again" Lilith says with a smile.
Nodding his head, Hadrian let out a sigh, the young Devil Slayer knew about the possibility of a rebellion as Lilith had spoken of whispers of a possible war, the young Potter just didn't expect it to be so soon.
"What should I do?" Hadrian asks with a frown.
"There are these things that the Humans have. Guilds, it would be a good place for you to train and grow in experience" the Demoness informs the young Devil Slayer.
As she looked down at her mate, a coy grin formed on Lilith's face as she leaned down.
"Hey, if you find some beauties in the Guilds do let me know. I have always wanted a threesome" Lilith says, causing Hadrian's eyes to widen in shock and surprise.
"What!?" Hadrian exclaims.
Giggling in amusement, Lilith disappears in a swirl of purple fire, leaving their home and returning to Purgatory.
Sighing slightly, Hadrian shook his head as his face went blank.
Knowing that Lilith would want him to join a guild, the young Devil Slayer headed upstairs, grabbing a black shirt and throwing on a black coat, Hadrian grasped Armageddon and strapped the sword and sheath to his back.
With not much to take with him and without the resources to take it, Hadrian left his home, magically locking it with his and Lilith's Magic as the only ones able to access the home and headed out, walking in a random direction in the hopes to find a Guild to spend the next who knows how long with them.
This will be fantastic Hadrian thought sarcastically, having a slight dislike towards Humans in general.
And so, in the year x773, the young Devil Slayer walks away from his home towards the people he would one day call his family.
(A.N: One thing I never really liked about the 3 Slayers types is that they never made the Slayers unique. I always found it odd as to me they were basically just a copy and paste of Dragon Slayers, sure I could understand the similarities since they are Slayers but they just seemed to similar in my eyes and so I made a list of the rankings on the categories of the different Slayers)
Power: (Raw Power)
1. Dragon Slayer 8/10
2. God Slayer 6.5/10
3. Devil Slayer 5/10
Healing: ( Broken Bone)
1. Devil Slayer (2-10 seconds depending on how much Magic the Slayer has IF the Slayer has Magic left)
2. God Slayer (2 days)
3. Dragon Slayer (4 days)
Magical Container: (How much the blood affects the Container growth)
(One thing I wanted to do was based on the blood within the Slayer or in some cases Lacrima, will affect the growth of the Magical Container within the Slayer, so if the Slayer were to do the same training then they will all have different results and growth)
1. God Slayer 7/10
2. Devil Slayer 4/10
3. Dragon Slayer 3/10
Magical Absorption: (This is the ability of how much Magic is gained through their element)
1. Devil Slayers 8/10
2. Dragon/God Slayers 5/10
Forms: (This is the final form of the Slayer and their true power)
1. Dragon Form (Dragon Slayer) 9/10
2. True Demon Form (Devil Slayer) 7/10
3. Divine Form (God Slayer) 6/10
Force forms: ( This is the incomplete state of the Slayer and the power increase)
1. Dragon Force (Dragon Slayer) 6/10
2. God Force (God Slayer) 5/10
3. Demon Form (Devil Slayer) 4/10
Senses:
Dragon Slayer: All 5 senses dialled up to 11 (Near impossible to fool) (Warning: Enhanced Senses will result in Severe Motion Sickness when the Slayer becomes stronger. Can be reduces through training)
Devil Slayer: The Slayer gains a 6th sense allowing them to detect any and all Magical Energies allowing them to detect any Demonic energy or blood, as a result Devil Slayers are capable of sensing other Slayers due to their altered energies (Warning: Too many large sources of Magic can cause the Slayer's vision to blur to compensate the overuse of the 6th sense. Can be reduced through training)
God Slayer: Within a certain vicinity the Slayer is capable of sensing any individual within their element or using said element, this in turns makes it nearly impossible to not be detected by the Slayer (Note: Despite the incredible use of this power its range is the size of a normal house when untrained but should the sense be trained it could reach up to a medium sized town. No repercussions for these senses)
Force Accessibility: (This is how easy it is to unlock and use the Slayer Force and how easy it is to gain the ability to master it)
1. Demon Form 10/10 (Note. All True Devil Slayers have gained their forms at incredibly early ages)
2. Dragon Force 3/10
3. God Force 2/10
Wrath: (This is the increase of Magical Power based on the enraged state of the Slayer)
1. Devil Slayer: 10/10
2. Dragon Slayer: 6/10
3. God Slayer: 4/10
(The reason True Devil Slayers are a 10 is due to the fact that their Magic/Curse is powered by dark emotions. So when the Devil Slayer is enraged then they will gain a monumental power boost.)
Resistance: (This is the resistance to the Slayers Element)
1. Dragon/God Slayer 9/10 (Warning. Dragon and God Slayers are not immune to the curse variant of their element)
2. Devil Slayer 1/10 (Devil Slayers have nearly no resistance to the same element unless it is their own Magic due to their unnatural ability to absorb Magic from any of their element within their vicinity)
Magic/Curse: (This is the chances of Slayers of the same element winning in a free for all against each other)
1. Devil Slayer 7/10 (The vicinity of the same element will allow the Slayer to regain Magic from the element. Warning: Consuming Devil Slayer Curse/Magic will result in a high chance of Death due to Demonic energy within the element. Do not consume or absorb True Devil Slayer Magic)
2. Dragon/God Slayer: 3/10
(One thing about all 3 Slayers is that they are all incredibly strong and have their own strengths. In terms of sheer raw power, Dragon Slayers have the win. In terms of lasting in a Magic battle the God Slayers have the win due to their larger Magical Container. In terms of lasting a battle overall the True Devil Slayers have the win.
But one thing that should be known is that should a Slayer fight anyone of the same element that are not a slayer themselves would have a near guaranteed win.
Ruthless: (How Ruthless a Slayer is naturally)
1. Devil Slayer 10/10 (Warning. The use of Devil Slayer Magic results in the suppression of positive emotions during its use, resulting in every True Devil Slayer to be incredibly ruthless when using their Magic in a real battle (Sparring/Training are partially affected)
2. Dragon/God Slayer 5/10 (Due to the fact that they are Slayers, both Dragon and God Slayers will be more likely to be brutal in combat due to their instincts programmed to fight to kill. (These instincts can be suppressed)
Danger Rating:
Dragon/God/Devil Slayer: 9/10
(Warning. All Slayers are incredibly dangerous and should not be angered. A fully realised Slayer is capable of destroying entire countries with nothing left in their wake)
(Warning. The combined forces of Devil/Dragon/God Slayer will result in the guaranteed destruction of the opposition.)
(MUST NOTE: This entire list should not be taken to heart when reading the story as all the Slayers will have different training methods, different Elements which results in different capabilities, different fighting styles and different experiences. The reason for this list is for the Slayers in general.)
