Part 12: Apprentices

King!SukunaRyomen x Servant!FemReader

Summary: You used to be just another servant among the army of humans operating under the command of the terrible king, Sukuna Ryomen. An ordinary human who only knows how to wash, clean and cook. Until one day, he notices something in you that you hadn't seen before.

Your gaze fixed on the target. The curse holding it was walking from side to side in a straight line as it mocked your poor aim. Practicing with the curses still wreck your nerves as not being used to seeing them as equals. They were supernatural beings that killed humans for hunger or simple fun, the main enemy in your universe. They were grotesque, mean and rude to all servants, constantly threatening that they would have been eaten already if it wasn't for King Sukuna. He is the one who decides when and how much the curses under his charge eat. Living in the castle of the great man-eating tyrant was like a rabbit living in a cage with hundreds of tigers.

Your arms tensed as you drew the bowstring taut. The feather at the end of the arrow tickled your fingers, tempting them to let go. It was your first time practicing with moving targets. You took a deep breath before your fingers let go of the string. The arrow swam like a salmon against the current until it stuck against the top of the target’s perimeter. You lowered the bow with an exasperated sigh.

“It was a good shot,” Kenjaku, who was supervising today’s training, cheered you on as he applauded your attempt.

“I don't need it to be good, I need it to be perfect,” you took another arrow out of the quiver.

You loaded the weapon and looked for the easiest target to hit from your position, noticing the curse approaching the center of your field of vision. You reviewed the advice Sukuna had given you in your previous lessons. As you remembered his soft purr against your ear, his beefy body next to yours, his breath against your cheek and his hands covering yours. He always caused you to lose your concentration, sabotaging your attempts to focus by projecting memories of their times together into your mind. You were beginning to miss him as your teacher.

It had been a couple of weeks since Sukuna told you that Yorozu would be his new sorcerer's apprentice. You faked surprise even though you had overheard their conversation and you were dying of worry inside. Your head was filled with all the possible scenarios where everything could go wrong. Being the older sister, your priority was to protect Yorozu at any cost. You had to make sure she ate well, slept in a comfortable place and that Sukuna didn't kill her at the slightest provocation. Luckily, you could watch your little sister practice her new skills from the library window while you studied. You had to be careful, though. If Kenjaku caught you distracted, he would hit you over the head with whatever he had in his hand to get your attention back.

You found Yorozu's powers fascinating. From what little you had picked up of her cursed technique, she could recreate any object she knew. Sukuna began her training by showing her the various weapons in his possession for her to recreate with the help of her cursed energy. They then went on to observe various insects and birds to test if she could recreate animal materials. She could. You almost fainted the first time you saw her grow a pair of firefly wings between her shoulder blades. She was getting more powerful every day and it scared you.

Even though Yorozu was emasculating and foolish, Sukuna could not afford to waste her abilities. A sorceress with a technique so powerful that she was willing to serve him was good, too good to be true. During her lessons, he had dedicated himself to analyzing her movements and every word she uttered to decipher what she wanted from him. He knew that human interactions are based on transactions. Communication, buying and selling, democracy, almost everything they have built is based on I give you something so that you give me something in return. Yorozu could appear to be happy serving him, but he knew perfectly well that it was a facade to get something.

You hated the idea of Sukuna being close to your sister. It bothered you to see them so close when the king was correcting her posture when it came to wielding a sword or inspecting her new creations. The thought of him taking advantage of her or hurting her in any way drove you crazy. You didn't want her to go through what you went through in your early days at the castle. Psychological, physical and verbal humiliation from a tyrant was something you wouldn't wish on your worst enemy, much less your little sister. Luckily, it didn't seem to be like that... for now. If Sukuna even thought of laying a finger on her, you'd make him pay.

The very thought of him being near her at all times, of him holding her hip, or of his voice being as gentle as it was with you caused you a discomfort you had never felt before. The next thing you knew, your fingers were no longer holding the arrow. The arrow flew along with your dark thoughts. You barely realized what you were feeling. Your body froze for a second until the arrow slammed into the head of the curse holding the target.

The curse staggered from the impact, but quickly regained its balance and yanked the foreign object out of its skull. You were shocked to see what you had done. You hurt a curse that was helping you. When you were about to apologize for your terrible mistake, the curse growled at you in annoyance as its skull regenerated by its reverse curse technique. It looked at you with a "If you do that again, I'm going to kill you" face. It was only restrained by the fact that Sukuna had ordered them not to mess with you.

“That one wasn't so bad,” Kenjaku smiled at you so you wouldn't feel bad about hurting someone by accident.

“I didn't mean to,” you replied sadly.

“A little more meaning and you'll be ready to kill someone,” Kenjaku joked, but you didn't laugh. The fact that he saw death as a joke bothered you, but you had learned to tolerate it. “Let's take a break, what do you say?” Your teacher changed the subject immediately upon noticing your discomfort.

You took off your quiver and gloves while your teacher told the curses to take a break. As we reached the coldest days of winter, Sukuna had gotten you a fur cloak so you could practice outdoors without dying of hypothermia. You put on the plush hat and wrapped yourself in the cloak as if it were a blanket. It wasn't that cold today, but the material was so soft you just wanted to rub your face on it.

You laid the equipment on the table as you watched Kenjaku carefully. He was a strange creature. Even though you knew he was a body invaded by a curse, you weren't afraid of him like Sukuna or Uraume. It helped that he had the body of a really attractive man. His long dark hair reminded you of the same night you see through the window. His traditional clothes were always ironed and moved delicately. His sharp, yet radiant eyes were what caught your attention the most, they looked full of life for someone dead.

“Tell me about yourself,” you asked him as if you were asking him to tell you a bedtime story.

“What do you want to know?” Kenjaku asked you, turning his attention back to you.

“Whose body are you possessing?”

“Don't you recognize it?” Your master raised an eyebrow in surprise.

“Should I?” He let out a loud laugh.

“Right. Sometimes I forget that you come from humble beginnings.” He loved to emphasize to you the abysmal difference in class between you. “The person in front of you is King Suguru Geto.”

You knew that name perfectly. Like King Satoru, he was a highly sought-after king among the nation's single women. After the death of King Geto, his handsome son had to take over the kingdom earlier than planned. He was rumored to be a kind-hearted, powerful man and had a brilliant mind as the only kingdom to have a direct relationship with the Gojo kingdom. Your mother went on and on about how much she wanted one of her daughters to marry him. You could only shake your head at her delusions. "As if we could get close to him" you thought amusedly.

“Is this man King Suguru Geto?” You asked, still trying to process that you were in front of the corpse of a king.

“It was,” Kenjaku said with a mocking smile.

“Did you kill him?” You asked even more surprised.

When King Suguru was killed, the news spread like wildfire among the villages. All you knew was that he was found dead of poisoning on the morning of the fifth anniversary of his coronation. His death had become quite a mystery, as he had no enemy kingdoms and was in good health the night before.

“I wish. I took over his body before they wanted to revive him,” Kenjaku replied.

“It is a pity that you died, your majesty,” you said as you bowed to him.

“There is no need to call me that, miss. Suguru Geto died years ago,” Kenjaku clarified, uncomfortably, at the bow.

“I believe the bodies are sacred. It’s the temple we live with all our lives and it is the memory we leave of our existence,” you explained. “Humans deserve respect, even if they are no longer here.”

You learned that when your father died. Your mother was so deep in her mourning that she didn't even want to get out of bed for the small funeral they had planned. You and Yorozu were the ones in charge of burying your father with tears falling on the ground, while Nanako and Mimiko picked flowers to place on his grave. The weight on your heart did not compare to the weight of the incomplete body as they placed him in his makeshift coffin, a wooden box they had built with rusty nails.

Your father passed away one night on his way home from work. He was walking through the tall grasses under the dark sky, excited to get home to see his family. The night was so dark that he never saw the group of curses stalking behind him coming. They pounced on him and did not hesitate to eat him alive. According to neighbors who lived nearby, the cries of pain and pity were so loud that they woke them up. When the neighbors arrived with torches and guns, your father was no longer breathing.

Your poor father was missing his legs, arms and part of his torso, but still, they moved his body carefully as if he were whole. Despite his tragic and unexpected death, your father deserved a decent funeral even though they didn't have much money. Among his entire family, they placed the coffin in the grave they had dug while a neighbor sang a ballad about his life. His wife and daughters did not keep their feelings in the minute of silence. Maybe he wasn’t the most brilliant, rich nor exceptional man, but he will be missed and they won't forget about him.

“Humans and curses have something in common,” Kenjaku approached you so you could look him in the eye. “Our bodies may rot and turn to dust, but our souls always live on.”

“Really?” You asked.

“I assure you,” Kenjaku took your cheek to caress it with his thumb in an attempt to comfort you.

Even though Sukuna was a ridiculously giant curse, he was a master of vigilance. Unbeknownst to you, he was always watching you. Whether it was with his own eyes or through one of his curses, he knew what you were doing and with whom every moment of the day. Today was no exception. He clenched his fist as he saw how close Kenjaku was to you. They should be practicing as he had instructed, not fondling you in broad daylight. Luckily, you had arrived at the right time to stop him. He walked out of the castle with Yorozu following him like a well-behaved duckling to where they were to stop the scene.

“Why the fuck aren't you practicing?” Sukuna scolded Kenjaku with a fierce roar. Seeing him, he and you bowed at his arrival.

“She had been practicing for an hour. Rest is important so as not to wear out the muscles of humans,” Kenjaku explained without a weight of guilt. Sukuna looked at you, there was no trace of guilt on your face either. "I'll let it go this time," he thought in annoyance.

“Sister, look at the dress the king got me! Isn't it pretty?” Yorozu approached you.

She opened the black cloak that covered her from the cold to show the white dress that Sukuna had commissioned Uraume to make for her practices. It had long sleeves, tied at the waist with a long ribbon and the skirt came below her knees so she could move freely. It wasn't as elegant or complicated as yours, but it was better than the maid's uniform.

“It is very nice. Our king has very good taste,” you said as you saw your sister happy about her new garment.

Yorozu has loved dresses for as long as you can remember. The delicate fabric, the pretty beading, the interesting designs and how the skirt moves on the dance floors. You remembered the birthday when your father gave her a set of crayons that was incomplete, she got so excited that she started running and screaming all over the house. Since then, you used to see her sitting at the small desk you shared, drawing her own designs. She was the reason her mother spent money on dresses. Yorozu would promise her that if she bought her one, she would flirt with the richest man at the ball. She never did, playing with her mother’s narcissist feelings.

“The king told me that if I behave well, I can have a dress as beautiful as yours. Isn't that right, my king?” Yorozu said before returning to Sukuna to hug him by the arm.

Your left eye twitched when she approached him with such confidence. You could never do something like that, afraid the king would take it the wrong way. You didn't understand how Yorozu could be so trusting as to act so naturally.

“I'll get you one when you prove you deserve it,” Sukuna said reluctantly because she was touching him without his permission.

Training Yorozu turned out to be more complicated than he thought it would be. She was a completely different girl from you, more so than he thought. She was shrill, distracted, and sometimes more cloying than chocolate ice cream. You wanted to push her against the ground like you used to, but this time you held back the urge because you were right in front of them. Yorozu squealed with delight at the response.

“Today I want Yorozu to learn how to use a bow,” Sukuna explained. “I want you to show me how much you have learned in this time that I have not been training you.” He turned to you, that only made you feel more nervous.

“I think it's an excellent idea. The best method of study is teaching,” Kenjaku commented.

“This is going to be so much fun!” Yorozu squealed excitedly. You just nodded complacently.

The first stage of the training was for Yorozu to create her own archery equipment. This would be of great help to them in the future. In case you were in the middle of an invasion, the moment you ran out of arrows, Yorozu could create more easily. She took your bow to examine it closely. Her black eyes examined its elements and details with utmost care, memorizing each part to perfection. Her hands molded to the wooden body and her fingers felt the thickness of the string. You had never seen Yorozu so focused in your life.

She handed the bow back to you to generate her own from her own hands. It was the first time you had seen her power at such close quarters. The wood, the strong string and the feathers of the arrows began to emerge from a strange energy emanating from her. It was a wonderful power if it could create anything. She could fix what was broken or help those in need. There were endless possibilities that Yorozu had at her fingertips. It was a shame that she had decided to use her power to hurt others.

Your sister ended up with a stronger and sturdier bow than yours that she had customized herself. The wood looked of better quality and the arrows had purple feathers to distinguish them from yours, which were white. Yorozu showed the king her new creation with a proud smile. You may not have agreed that she would fight for the king, but the important thing was that she was happy.

The afternoon passed slowly as you taught Yorozu everything you had learned so far. You taught her the correct T-position, how to release the arrow correctly and how to hit as close to the center as possible. Sukuna and Kenjaku were watching from a considerable distance, they could hear all the advice that both of them had given you in the last weeks.

Sukuna was proud that you had really memorized everything he had taught you. He was beginning to see the leader within you come to the surface. Just as he had planned, but this was only the beginning. There were many more things you had to learn. All at its time.

After an hour of basic archery class, Yorozu was ready to aim on her own. She loaded the bow, held the arrow in a T-position and looked at the target as you had taught her. She released the arrow with force and missed the target. She missed once, twice, three... so many times to the point that she got fed up and broke the bow in half with the help of her knee. Kenjaku looked at her in grief, while Sukuna grabbed his forehead in disappointment. You approached your sister to calm her down.

“Take it easy. It's a skill that takes practice,” you told her with a smile to cheer her up, just like Kenjaku sometimes did with you.

“I need motivation.” Yorozu said before creating another bow with her cursed technique. That's when she got a great idea. “Let's hold a competition. Whoever hits the target closest wins.” She encouraged you. This sparked the interest of the teachers that were looking at them.

“Sounds like fun,” You told her excitedly. This would be like playing with her again like they used to do when you were kids.

“Let's bet something to make it more interesting,” Yorozu said excitedly.

“I like that idea.” You thought of something you wanted from her. “If I win, I want you to give me a foot massage,” you told her with a wicked little smile.

“Ew, gross.”

Sukuna smiled to himself to see you laughing and joking like that. It was a side he never thought he would see up close. Being a large, carnivorous curse, those below him on the food chain feared him with good reason. He was so used to seeing you cry, suffer and beg for your lives that he had forgotten that you can also rejoice, thrill and be passionate. I had completely forgotten that you were once a free girl with a say who tells jokes, plays with her sisters and enjoys cooking for her family. He would like to see you more like that, to be the real you without being afraid of him.

Unfortunately, if Sukuna wanted to achieve his goals, he had to keep your leash short. You had to be the perfect wife so that you would become the perfect mother that his future heir would need to become a strong leader. There was no time for the foolish things humans like to do. Sukuna's face returned to its serious countenance.

“But if I win..." Yorozu thought out loud until she hyper-focused on what you were wearing. “I want your dress.” She dared you with her dark eyes.

You weren't sure you could do that. Underneath your fur cloak, there was a sky blue dress with beautiful gems encrusted on the chest that flowed down to the skirt. It was one of the dresses Sukuna had given you. You couldn't give away something as precious as that.

“The king gave it to me. I can't give it to you, choose another prize,” you said to Yorozu while looking at Sukuna.

“Oh, come on! I've seen you wear seven different dresses in the last week! I don't think our dear king will mind if you give me one, right?” Yorozu looked at Sukuna with sad puppy dog eyes.

You really liked that dress. It was the one that best accentuated your body of all the ones you had. It had hanging sleeves that allowed you to archery comfortably. All the other dresses were nice, but that one was your favorite. You looked at Sukuna as if you were asking him to say no.

“Bet it,” Sukuna finally spoke. You and Kenjaku were surprised at how easily he had agreed.

“You are the best, my king!” Yorozu shouted happily. “Let's begin.” She shook your hand to start the competition.

Being the one who had been practicing the longest, you went first. You saw the still target 50 meters away from you. You took a deep breath as you got into position. It was perfect. You pulled the arrow all the way under your chin. It was perfect. Your fingertips barely tensed the string as you drew the invisible trajectory. It would be a perfect shot. You could feel it. Finally, you released the string and the arrow traveled at full speed until it hit the top perimeter of the yellow center. It was as close as you've ever come to hitting the bullseye.

“Good job, miss!” Kenjaku congratulated you as he clapped like a proud father. Sukuna just analyzed the target. It wasn't a perfect shot, but it was very close to it.

“Not bad,” Yorozu said competitively as he positioned himself in front of the target. “Now watch and learn,” She smiled wickedly. She was up to something.

She placed the arrow on the bow and did exactly what you did. Everything rigorously as you had dictated during the lesson. You analyzed what she did in case you could give her any advice. Yorozu was confident that she would win. Once she had the center in her sights, she made the arrow and bow increase in size under her fingers with the help of her technique. You recoiled as you noticed the drastic change. Unable to cope with the new weight of your weapon, she released the arrow to lower the bow as quickly as possible. You followed the arrow's journey with your eyes as your mouth opened at the tremendous impact, destroying the straw target completely.

“Well, I think there is a clear winner,” Yorozu looked at you with malice.

“It's not fair. You used your technique,” you said annoyed.

“You never forbade me,” Yorozu declared. “Now, don't be a sore loser and give me my prize.” She raised her hand to you.

“Now?!” You groaned as you slammed your cloak shut. Yorozu nodded energetically.

The blush of embarrassment crept up your cheeks. It was embarrassing, but you had accepted the deal. It hurt to give up that dress, but at least Yorozu would have something nice to wear, just like you. You closed the cloak and reached for the ribbons that tied it behind your back to get rid of the dress that wrapped around you. Luckily you were wearing a corset and a white bottom, so you wouldn't be naked. You jumped out of the dress and gave it to her.

“Yay!” Yorozu shouted excitedly.

She yanked off her white dress, revealing that she was completely naked underneath. Kenjaku and you watched in horror, while Sukuna simply looked away. He really hated to see her naked during practice, so he forced her to at least put on a haori.

“Why aren't you wearing any underwear!” You scolded her, embarrassed.

“Why are you wearing underwear?” Yorozu asked, playing it down as she put on the new dress.

She pulled the dress up from the neckline and then put on the sleeves. She tied it in the back as best she could on her own and modeled it to her sister. It fit her...just fit her. She didn't quite fill out the bust, the sleeves swam, and it was tight around her waist. Some parts were tight, while others were too big. She could wear it, but it just didn't look right.

“How do I look, my king? Don't I look beautiful?” Yorozu asked Sukuna as he modeled the dress for her. He analyzed her for a second.

“I ordered that dress especially for your sister, it is custom made for her,” Sukuna explained when he saw that it did not fill the bust. “It is unique and unrepeatable," Sukuna said as he looked at you.

You closed the cloak over your chest at those words. Even though you knew he was talking about the dress, a part of you wanted to think that he was dedicating those words to you. Your cheeks reddened at the thought of something out of your imagination. Kenjaku noticed your embarrassment and thought you were embarrassed about being in too little clothing. Quickly, he approached you.

“Put this on, miss," he said as he took off his yukata.

You blushed more when you saw the splendid body the late king was hiding. Slim, but well-defined arms, smooth biceps and abs you could carve clothes on. Your lips parted slightly in shock. This was your first time seeing a shirtless man.

Sukuna was annoyed at the scene he was seeing. Kenjaku was too close to you again, too close for his liking. "Is this how he usually treats her when I'm not around? I should increase my vigilance," he wondered as he watched the scene with disdain.

As Kenjaku was about to put the yukata over your shoulders, his arms came off his body in the blink of an eye. You were stunned for a second before you could comprehend what on earth had happened. Your mind was awakened when you heard the thud of his arms crashing against the grass, still holding the yukata. Sukuna approached you, pushing Kenjaku by the torso away from you.

He picked up the garment and draped it over your shoulders. You didn't know what to say about it. Sometimes his actions lacked logic and you found it hard to understand. His thick, clawed fingers brushed against your skin as he helped you tuck your arms into the sleeves. His hands traveled gently to your waist to tie the bow that closed the yukata. He was acting like a fairy tale prince...well, minus the fact that he cut off someone's arms to do it. You could only thank him with a whisper that only he could hear.

Yorozu squeezed the skirt of her dress tightly, not intending to hide her jealousy. Why was Sukuna treating the woman who didn't want to marry him so tenderly? It wasn't fair. If she had arrived at the castle earlier, he would be in love with her, not you.

Kenjaku watched the scene intently as his arms slowly regenerated. On one hand, he had a spoiled sister who wanted the king's attention. On the other hand, he had the sister who had no idea what was going on. And last but not least, a jealous king who hasn't realized he's jealous. “I think I can do something about this,” he thought.

“Training is over today,” Sukuna grumbled before walking back to the castle at a quick pace to pretend nothing had happened, leaving you with your heart in your hand.

“Yes, my king,” Yorozu, Kenjaku and you said at the same time along with a farewell bow, each in their own world of thoughts.

“Sis, I’ll give you your dress back for a foot massage,” Yorozu told you reluctantly once Sukuna entered the castle.

“Deal,” you said with a smile, happy to have the dress you loved so much back.

“Shit, shit, shit…” Sukuna scolded himself as he walked through the castle halls, hiding his reddish face in shame for letting his emotions get the better of him. It was a good thing the servants feared him, because he didn’t want to talk to anyone. He locked himself in his office with a slam and leaned back in his chair. If he closed his eyes, he could still see your eyes looking up at him in disbelief as he felt your warm skin beneath his cloak. He brushed his hair back in exasperation. “What the fuck is going on?” he thought.
