Chapter Text
"Ah, welcome my King and young Prince." The Keeper greets the two who enter the shop. The King of Monsters and his son, his heir, Prince Sukuna Ryomen. "What can I help you with today, Sire."
"My son's thirteenth birthday is today, it's only fitting that he receives a pet. I need a young one, preferably small and not yet so... difficult." Sukuna's father, Kenjaku, speaks calmly as he explains what he desires for his son to obtain. Kenjaku is an intimidating, demonic man with quite a few offspring but none are as promising as Sukuna, whom he named his heir when the boy was only six years old. He's a powerful demon and will make for a proper, tyrannical King.
"I see, happy belated birthday my Prince." The Keeper's lips curl into a much too large grin, his teeth sharp and his eyes glowing a vile golden shade.
Sukuna narrows his glowing, crimson eyes at the lower-level demon. "How dare you make eye contact with me, such insolence." Sukuna snaps, earning a high-pitched giggle from the keeper.
"My apologies, young Prince. Sire, I know of the perfect pet. He's on the younger side, purebred, not yet deflowered, and still obtaining his mental innocence. He's unaware of the horrors other pets tend to be aware of, he's certain not to fight." The Keeper leads the royals to the young boy he has in mind.
On the way, they pass other pets of all ages in cages just big enough to allow them to sit up, lay down, but not big enough to stand.
Sukuna avoids looking at the pathetic, dirty pets. He brings the hood of his black cloak over more, repulsed by these unworthy beings. "Father, is this necessary?" He grumbles, believing it to be useless to have to care for such a weakling.
"When you're King, this pet will be the one to carry your offspring. Lower-level demons are manipulative creatures, they will desire your power and they only follow you because you're stronger. A pet is loyal because you train them to be. We'll see if this pet is worthwhile." Kenjaku responds, gaze as cold as ice.
The only light throughout the underground shop resembling a deep cave with numerous passageways and doors is from the firelight. Demons have near perfect eyesight in the darkness but nowhere near as perfect as Vampires.
"This boy has no name." The Keeper informs them as he takes out a metal ring of keys. He selects the correct one, inserting it into the metal and wooden door that creaks as it opens. A small boy is sitting on a thin blanket on the stone floor, a chain around his frail ankle to make certain he doesn't escape. He looks over, skin pale and lips a soft pink. His eyes are a bright, emerald green and his hair is wild and dark.
The Keeper doesn't get to say a word because it's already been decided. "Father, I want this one." Sukuna demands, feeling intensely drawn to the small thing.
"Very well." Kenjaku nods towards the Keeper in approval. The shifty low-level demon makes his way into the room. He unlocks the chain around the young boy's ankle, grabbing his arm and bringing him along as they make their way towards the entrance. Sukuna observes the boy who is rather thin, his feet pale and very little. Is this pet truly just a weak, useless thing? Sukuna would kill him if so, Sukuna despises things like that. How is such a boy supposed to carry Sukuna’s heirs? He looks like he’d break easily.
"Here's his paperwork and the contract is here. All you need to do is sign at the bottom and feed the pet your blood." The Keeper explains, grabbing the young boy's hand and slicing the tip of his finger. He jolts, bottom lip trembling as the Keeper wipes the boy's blood onto the contract.
"Why do I need to feed it my blood?" Sukuna questions, looking towards his father.
"The pet will rely on you to feed, otherwise this thing will be nothing more than a bloodwhore to anyone." Kenjaku explains, looking at the small pet. The shirt he's wearing is much too large on him and ripped up, it hangs off the side, revealing his pale shoulder.
Sukuna sighs, grabbing the knife from the Keeper. "Very well." He accepts, slicing his finger and signing on his part of the contract. He hands the knife back before bending down so he can be somewhat eye-level. "Look at me." Sukuna demands, removing his hood. The pet makes eye contact with him, the purity so strong Sukuna can smell it. It makes his mouth water.
"From now on, your name is Megumi." Sukuna says, causing the boy's eyes to widen.
"M-me?" He stutters in disbelief, voice soft and gentle. Sukuna nods his head, bringing his hand up. He pulls up his sleeve, showing it to Megumi who looks rather puzzled.
"Feed from me, Megumi. If you do not, I will force it down your throat. Do you want that?" Sukuna questions, to which Megumi shakes his head side to side. He seems hesitant but he moves closer to Sukuna. He timidly places his small hands onto Sukuna's arm, licking his smooth lips. He leans close, his eyes fluttering shut as he smells Sukuna's blood from beneath the flesh. His milk fangs pierce Sukuna's skin, the taste of his blood is so delightful that Megumi is in complete awe.
Truly, Megumi is starved. The little bit of soup provided isn't enough to ease the hunger. Sukuna's blood causes a wave of dizziness and despite Megumi not wishing to stop, he knows he must. He pulls back, a bit of blood trickling the corner of his mouth. His cheeks are flushed and he's breathless, his emerald green eyes glowing. He licks the bite wound before Sukuna heals, wanting to clean what is leftover.
Sukuna wipes the corner of Megumi’s mouth, pushing his thumb into the boy’s mouth. His little lips wrap around his finger, suckling the blood off. He looks at Sukuna with those bright, innocent eyes and Sukuna feels something in him ignite.
Megumi has fallen asleep in the carriage, curled up like a kitten. Sukuna looks over the paperwork provided. Megumi is an Omega and six years of age. A purebred Vampire as well, those are quite rare. That means he will have a magic gift later on, that could be useful.
"What a precious little pet, what changed my stubborn son's mind? Was it because he's rather pretty?" Kenjaku questions in amusement.
“Instinct.” Sukuna replies, setting the paperwork down onto his lap. “That’s all it is.”
“Train him well and remember, because he belongs to you he will become a target of rather vengeful and unsavory demons.” Kenjaku reminds his son who looks like he couldn’t care less.
“If he dies or gets pregnant by a lower level being, I’ll just discard of him and get another.” Sukuna says this but Kenjaku knows his son best. He may say he doesn’t care but demons are rather possessive of what belongs to them. He’ll behave that way towards his pet whether he realizes it or not. Kenjaku will let him figure it out on his own.
Megumi frowns, looking at the food laid out before him. He has three children eagerly trying to get him to join their picnic, as they called it, and eat with them.
“It’s safe, I swear! I’m Prince Yuji, fourth son of the King. You don’t have to be afraid!” He smiles, his sharp canines sparkling. He has short, pinkish hair and scars under his eyes.
“You’re small, you need food.” The other one speaks, his hair dark and long with a marking across his nose.
“Where are your shoes?! Your feet are far too fragile!” The other one fusses, hair white and short with a pink streak across. As he comes closer, Megumi takes a step back only to bump into someone behind him. He hesitantly looks up, relief washing over him as he sees Sukuna.
Sukuna isn’t looking at him but glaring ahead at the others. Megumi hurriedly hides behind Sukuna, clutching onto his clothes.
“B-brother Sukuna, we just wanted—“
“Who gave you permission to speak, brat?” Sukuna’s murderous aura cannot be ignored and it has Megumi clinging tighter to his Master. “Uselessly playing games, no wonder none of you are worthy of father’s attention. It’s pathetic.”
“Sorry, brother Sukuna.” The one with white hair bows down, submitting to the more powerful sibling.
Sukuna picks Megumi up, tossing him over his shoulder as he makes his way back to the castle. Megumi stays completely still, knowing better than to move around much. He’s only been here for a week but it’s much better than that dark room.
His Master is a bit scary but Megumi likes him the best.
Sukuna throws Megumi onto the bed, startling the much younger. He pins Megumi down, sticking his fingers into the boy’s mouth and grabbing his tongue. Megumi whines, tears welling up in his eyes. “If you talk to those bastards, I’ll rip your tongue out of your mouth.”
He removes his fingers, his eyes glowing in the barely lit bedroom. “I didn’t talk to them, Master, I promise. M…Megumi was looking for you.” He sniffles, voice timid. Sukuna leans down, licking Megumi’s tears. The sensation is a little strange but Megumi doesn’t push his Master away.
Large hands slide under Megumi’s shirt, caressing his skin. He’s so thin, so starved, there’s hardly any baby fat on his tummy.
Sukuna kisses Megumi, aware the boy is clumsy and doesn’t know what’s happening.
The feeling of Sukuna’s tongue exploring his mouth is much softer than when he stuck his fingers inside and grabbed his little tongue. Megumi finds it difficult to breathe with his Master doing this unusual thing to him.
Trembling, small hands grip onto Sukuna’s shirt. He pulls back, a string of saliva connecting from their mouths. Megumi’s face is flushed, his lips glossy.
“Your heat needs to come soon.” Sukuna comments, impatient.
“My… what?” Megumi questions, puzzled.
Sukuna places his hand onto the boy’s tummy, his hand larger. “When your heat comes, I’ll be deep inside you here and place a baby into your womb.”
