A/N: Heyo Mayo! *a shitload of angry people turn and look like they're ready to rip me to pieces* So...ehe...I've been gone awhile. Well, shit.

JUST IGNORE ME AND GO STRAIGHT TO THE SUMMARY!

Summary: What if Asta was the son of a demon? And not just any demon, but the Demon King himself? Heavily inspired by chapters 96 and 97 of the Black Clover Manga. Crossover between Seven Deadly Sins and Black Clover.

Standard disclaimer applied.

P.S.- I have no idea if they have surnames or not, so I just made some up.

Enjoy!

Demon-Blooded

Chapter 1: Son of the Devil

The Demon King looked over his kingdom, watching his three young sons try to best each other in combat atop one of the many distorted rock columns nearby his castle.

Although, in reality, the eldest was pounding them into the ground with such a grisly ease, that the king began to become impressed with his ability.

His darkness flared, and an equally devious smirk draped over his features. Maybe another child- another son- to train was a way to truly test his boy's mettle.

And another son, he was granted through his queen. A son who resembled the eldest closely- despite the marking signifying his heritage carrying a slight difference in appearance- namely, the line that extended under his eyelid.

"Astaris. Astaris Amon." The Demon King christened his wailing newborn, his hopes for the boy already high enough to reach the heavens.

Soon enough, the child stopped crying his arrival and opened his onyx eyes to see a giant of a man, with a marking as dark as night on the crest of his forehead, covered in metal plated armor that was meant to resemble a warrior returning from the battlefield that he did not recognize, but knew was his father. Astaris reached up for the bearded man's face in an attempt to tug on his wavy, silver locks with his petite, pudgy hands. Meliodas, the eldest, loomed over the young boy with disinterest written all over his face, only to smirk when Astaris' attention shifted over to him.

"He'd make a fine Commandment. And perhaps, an even better swordsman. Chandler would adore having him as a student." The blonde teenager commented, inspecting the newborn like a hawk ensaring its prey. Estarossa, the secondborn child, bristled with envy at the newborn recieving such attention from his elder brother and hardly noticed when Meliodas brought Astaris to him.

Astaris only cooed, not undertanding why Estarossa was looking at him with a contemptful stare. He reached out, much like he had with his father, and tugged on his brother's orange collar, effectively startling him.

Estarossa finally peeked down at the babe, who, whilst he had been wailing, had been wrapped into fine cloth to keep warm. And as soon as his gaze met that of Astaris' curious eye, did he realize that Astaris, just like Meliodas said, would make a wonderful demon soldier. "Hmm..." the silver haired demon began to ponder, much to the confusion of the baby firmly grabbing his collar.

"Estarossa, what are you doing?" Meliodas questioned.

"I...have no idea," the younger demon mumbled. He slowly removed the baby's hand from his raised collar to prevent further embarrasment, noting that his collar was now rather soiled.

Zeldris, the third son, looked heavily disinterested in the boy, even when Astaris looked his way.

"Let me guess," the raven haired boy started, his voice only just beginning to change. "I'm in charge of this pipsqueak until he's old enough to walk?" he snarked, earning a glare from Meliodas.

"No. You're in charge of helping Father train him when he's old enough." Meliodas calmly returned fire, dark miasma beginning to float around himself and Astaris, as the newborn had fallen asleep in his arms.

Zeldris returned the look his eldest brother gave him, hand on the hilt of his blade before both of them felt their father's overwhelming power descend upon them.

"Enough." Growled the king. "I will not have this disrespect in my palace."

Zeldris clenched his teeth. "Of course, Father. It will not happen again." He begrudgingly muttered. Sparing one last glance at the infant, Zeldris clicked his teeth and walked out of the room without another word.

The Demon King knelt down to the short boy, hoping to observe his youngest as he slept.

'I can tell that Astaris will make a great man...Maybe a great king, should his brothers not want the throne.' The Demon King mused to himself, before the messenger came through the grand doors in haste, the sound of exploding shrapnel following closely behind.

"Your Majesty! One of our batallions has rebelled! What's worse, they're gathering up other squads from the army!" He yelled in fright, causing Astaris to wake and scream. And if that hadn't been enough, his shrieks went heard throughout the palace and the now destroyed palace gates...straight to the rebels.

Who no doubt opposed to having a new member of the royal family- especially if said newborn was being loud enough to wake the dead.

Meliodas reached out with his darkness for the greatsword that hung on the nearest wall to arm himself.

He might have cared about being the strongest more than anything, but hell would freeze if he couldn't defend his castle(or his brothers, but he would never admit it aloud) before anything else.

Gripping the base of the sword's hilt, Meliodas steeled himself for what was to come, handing Astaris over to one of the servants before he gave out an order.

"I have no doubt that whatever the hell started this wants Astaris dead...so take him to the human world and hide his powers. As of today, he is Asta." Meliodas commanded. His father agreed wholeheartedly, summoning forth a massive blade nearly half his height to fight with.

Estarossa summoned forth seven blades made of shadows, each one hovering in the air beside their master as if waiting for a command.

'And as much as Astaris is Brother's newest protege...he is still my younger brother.' he mentally determined, gripping one of his many weapons in preparation of the battle ahead.

"Estarossa! You and Zeldris are with me to the South Gate! You, with Asta! Go west and take him! On the chance that you are wounded, leave him in a populated area with an orphanage, church- whatever the hell you end up next to, I don't care!" Meliodas barked, dashing forth to quell the resistance. The servant, not needing or hearing any further orders, dashed off into the opposite direction.

Along the way, Meliodas calmly went over his plan in the darkest confines of his mind as he dashed to the South entryway, his sword slung across his shoulder. 'Asta should be fine. If the rebels are entering through the South Gate, then I've no need to worry.' But instead of not worrying, like Meliodas had hoped, his thoughts drifted to a pit of concern for his youngest brother. 'But if something goes wrong, then I, nor Estarossa or even Zeldris will be there to ensure his safety. And as his future teacher and his brother, him living is among my ever-growing list of concerns.' Meliodas internally grumbled.

He was a leader of the Ten Commandments, dammit- he had no time to ponder his musings, only fight a battle and win.

The short blonde shook his conscience clear of those thoughts, stopping his run when he reached the grand doors and swung his colossal blade in a wide arc with a war cry.

Unfortunately, Meliodas' worries were proven true.

The servant, carrying the newborn prince in her arms, had been wounded across her torso, but had managed to escape with him, finding a gate from the underworld to the human world from an aerial standpoint, slipping through just as it closed.

The bad thing about that was, whilst Asta had come out unscathed, she was dying from blood loss and almost out of hearts. Landing none-too-gracefully before a church near a skull nearly twice the size of the demon king himself, the dying woman placed the young prince next to a basket where a raven haired boy lay fast asleep, unaware of the young demon prince whimpering beside him as the dying demon wrote 'Asta' in her own blood before the reaper came to claim her at last.

It didn't take too long for a sister of the church to open the door when the blonde boy began to cry loudly, flailing around a bit. Looking around, she glanced down and noticed two infants lying at the doorstep- one in a basket and in a shirt and necklace, tucked away in a blanket, and the other covered in a blood-soaked blanket and nothing else besides what looked to be his name written in blood by...the...

Oh, dear.

A bleeding corpse lay next to the wailing boy, their fingers covered in the very vermillion that the child's name was scrawled in.

"Father, come quickly!" She called out through the church doors, not seeing the marking on the blonde boy fade away completely from sight.

The head priest came running as he was beckoned and saw the boys at the doorstep just before his eyes landed on the dead woman.

"Dear Lord..." He muttered, reaching down for the infants when he saw the name written on the concrete.

"'Asta'?" The greying man whispered aloud, enough to make the bloodied boy tone down his crying a bit. Sparing a saddened glance at his fellow member of the church, he lifted the wailing child into his arms, his black haired companion gathering up the other boy in her lithe arms.

Sending a heartfelt prayer to the woman who brought forth the wailing infant- and presumably the still sleeping babe-, the aging priest brought the unknowing demon prince into the monastery.

A burial was in order for the morning.

A/N: I LIIIIIIVE!*insert corny ass Mushu moment* I am so sorry for my absence...I have no excuse other than total procrastination and lack of motivation. Planning my original novel is like trying to plan a trip to the moon(Lord knows this won't ever happen), and then there's sophomore year of classes. All in all, just absofuckinlutely peachy. If Meliodas seems a fair bit OOC, along with Estarossa, then know that it's probably because of the tiny headcanon that I have that before he defected, Meliodas would have been FIERCELY protective of his younger brothers as a youth. Then again, it's probably because he's the eldest child and I have my own little fantasies about it.

But enough of that for now, have a Seven Deadly Sins/Black Clover Crossover for your reading pleasure! And please send feedback- I thrive off of your comments in order to be constantly inspired.

If some things strike you as odd, PM me for clarification, or if you're a guest, ask me any questions by review. Chapter 2 should be done by around New Year's Day, or a bit later- I'm in the middle of writing that one still, and when I'm done I'm going to write 3 and 4...depends on what kind of schedule I end up with in the long run. Also, if anyone has any ideas that I can use, or even possible suggestions, please feel free to tell me! If all you have for me are flames, though, keep your rude comments to yourselves, why don't you.

NEXT UP: Demon-Blooded Chapter 2: Seven Beats, Severed Power

1) Chapter 2 of Son Natsu: Journey of the Dragon King is about 75% finished! It took me nearly two years, but I'm still doing it whenever I can!
