Hey guys! So, I have another fic based on the Laboratorium CYOA. This one is for JJK. Different build of course. Obviously, this is a harem. I don't own JJK.

Chapter 1: The Beginning

"Spirits…spirits…please reveal an animal that the student council president is weaker than!" A group of three students chanted together. They were sitting in a small classroom at a small table with an Ouija board on it. The trio had one finger each on the board, all bunched together. They each moved their fingers to land on four different hiragana, spelling out 'Sea Angel.' They doubled over in their chairs, laughing boisterously. "Seriously?! A slug?!"

"Occult Research Club!" A stern voice bellowed as the door slammed open. A young man with plain black hair and glasses was revealed, wearing a typical boy's Japanese school uniform, a black buttoned up shirt and pants. He was skinny in build and didn't seem remarkably strong on the surface.

"Hey, President Plankton! What's up?" One of the trio commented while chuckling. He was a teen with spiky pink hair. He wore the same uniform as the young man shouting at them, but he wore a beige hoodie over his uniform shirt. He was the complete opposite in build too, as even though the uniform was loose, it was still able to show off his muscles.

"I'm gonna kill you, Itadori-san…" The president seethed, before coughing into his fist. "Your club didn't submit its activities reports again! There's no space for clubs like that in this school! Not anymore!"

"So, what are you gonna do about it?" Itadori asked, unconcerned.

"I'll tell you what I'm going to do! Turn this room into the changing room for the girls' track team starting today! So take your friends and get out!"

"Girlfriend and friend," the pink haired teen corrected.

"Yuji-kun…" Said girlfriend blushed from her boyfriend's remark. She wore a girl's uniform, which consisted of a white shirt, a tie, a sweater vest, and a skirt. In addition, she wore socks long enough to reach a few inches under her knees, sneakers, and glasses. She had short brown hair that reached just a few inches above her neck. Physically, she was very attractive- her bust was average, but her thighs were thick and her ass was round and big. (Something Yuji was not afraid to compliment).

"Why're you red, Secchan?" The pink haired young man asked innocently, while his eyes showed nothing but mischief.

"Y-You know why…" Secchan pouted, knowing her boyfriend was trying to tease her.

"Ahem…my apologies." The bespectacled president coughed with his own blush. "Regardless: Sasaki Setsuko, Iguchi Takeshi, and Itadori Yuji! Your club is hereby disbanded! Leave now!"

Iguchi Takeshi, the last member of the Occult Club, was pretty tall. He wore the same boy's uniform but wore brown loafers. His black hair was gelled in the back to keep it standing.

"I wouldn't mess with our club if I were you…" Yuji warned. As if on cue, his girlfriend slammed a pair of two books on the table. The club members each had sinister and spooky expressions on their faces as they stared at the student council president.

"What's that?" he asked with a deadpan expression. "A waste of my time?"

"It's new paranormal activity…and it's related to this school!" The brown haired young woman declared. "You know our Rugby Field was recently closed off, right?"

"Yeah…" The president nodded as he stroked his chin. "A lot of students who used it were getting sick. Some were even hospitalized. Why?"

The girl grinned. "Don't you think that's strange? They're rugby players for crying out loud! Strong, athletic, healthy…" She paused before her grin widened. "And not as handsome as my boyfriend!"

"Is that last part really necessary?" The black haired president asked.

"Thank you, Secchan!" The pink haired young man exclaimed happily with a bright smile on his face.

"Yes, yes it was." The brunette grinned. Her expression became serious. "The players stated before getting sick…" She opened the top book, and quickly began flipping through its pages. "They heard strange noises and voices." She smiled as soon as she found the page she was looking for. "That's where this newspaper article from 30 years ago comes in!"

The bespectacled young woman's finger pointed to a piece of a newspaper article. The headline for the article read 'Construction Company Employee Missing!'

"Yoshida-san, who worked at a construction company, went missing!" she exclaimed excitedly, slapping the paper for emphasis. "He was last seen here! At this school, during construction! At the time, Yoshida-san was in debt! He was being targeted by loan sharks!"

"Where's this going…?" The stern president wondered with a raised eyebrow.

Her glasses shined, then she pumped her fist. "It means Yoshida-san's body is buried at the rugby field! His lingering spirit is why so many players got sick!"

"No…it can't be…" The black haired president uttered with shock in his eyes.

"Oh, but it is!" Yuji chimed in with a grin.

"Believe it, Pres!" Iguchi added.

"No, it really can't be." The student council president deadpanned. "Ticks were the reason, not some spirits you three conjured up!"

Sasaki deflated. "I'm such an idiot…" she muttered with a depressed look in her eyes.

"And besides, you three shouldn't be wasting your time with kids' games! You three are third-years! You should be more focused on activities that are respectable!" The President chided sternly.

"Occult Research is respectable!" The pink haired young man fired back. "We're hypothesizing and discussing the paranormal and supernatural here! It's a perfectly fine club activity, President Plankton!"

"Stop calling me that!" The black haired president snapped, shark teeth showing suddenly appearing in his mouth. "I'm not even that weak! I'm skilled in Aikido!" He pointed at Yuji. "Besides, the biggest problem here is you, Itadori!"

"Do I smell bad?" The young man asked as he quickly began to sniff his pits. This caused Sasaki to giggle while Iguchi laughed loudly.

"No!" The black haired president exclaimed. "You transferred clubs, remember! You filled out an application to become part of the track and field team! And when a club has less than three members, that club must disband!"

"Eh?" The pink haired teen's eyes blinked as he processed this information, before shaking his head. "No, I didn't."

"Yes, you did, you idiot!" The student council leader exclaimed. "You submitted a club transfer application yesterday!"

"When would I have had the time? I was visiting my grandfather in the hospital yesterday!"

"And afterward, I came over to his house for a study date." Sasaki added. "Besides, it'd be strange for him to make a decision like that and not mention it to me."

"Well if you didn't, then who did?" the bespectacled president asked, bemused.

"I did." A man walked into the room. He had black hair done in a buzz cut and wore a black turtleneck with black pants. "With you on the track-and-field team, we would win nationals with ease! The team needs you, Itadori!"

"For the last time, I'm not joining!" Yuji bemoaned. "You people are worse than yanderes!"

"Isn't that a little far?" The black haired President asked.

"No! At least a lot of yanderes are hot!" The pink haired teen admitted with no shame whatsoever.

"You're not wrong." His brunette girlfriend agreed with a smirk.

"And Coach Takagi!" The President said in a disappointed tone. "This is against the rules! You're a teacher! You can't be sketchier than these three!"

"Thank yo-Hey!"

"None of that matters!" The track coach exclaimed with a fierce gaze. "The only thing that matters to me is winning! And I'll do whatever it takes to win! It's why they hired me as a coach after the last one failed!" He sighed. "However, I'm not unreasonable. So, how about a little wager, Itadori?"

The pink haired young man sighed. "I'm listening…not like I got a choice."

"Shot put. If I lose, I give up on you. However, if I win-"

"I accept!" The young man agreed with no hesitation.

The coach blinked. "I haven't even told you what happens if I win."

"It doesn't matter, I'm winning!"

The black haired coach grinned. "If you say so."

Iguchi facepalmed. "He's in for it now."

"He's new, so I can't blame him." Sasaki grinned while shaking her head. "He's in for a reality check if he thinks he can beat Yuji."

"Bring it on!" The pink haired teen smirked, confidence oozing off of him. After all, there was a reason why he was nicknamed 'The Tiger of West Junior High'...and why it carried over to high school.


"Nice, I win." The pink haired teen smiled as he admired his handiwork. He had thrown the shot put ball 30 meters. It would have traveled further, but it had instead struck the nearby soccer goal, denting the frame heavily. Regardless, it was enough to beat Coach Takagi's measly 14 meters.

And the world record.

"I-I…h-how?" Speaking of the coach, he was left almost speechless by the result of the competition. If Yuji was a betting man, he had probably expected an easy victory against someone inexperienced. Unfortunately, he had miscalculated.

"Another victim of the Tiger of Sugisawa." A male student commented.

"He's been doing this for years." Added another student. "You know how many coaches have tried to recruit him only to turn them down?"

"I've lost count. And when a coach has issued some type of last-ditch challenge, it always flops."

"Itadori-san is just built different."

'They're not wrong.' Itadori thought as he got ready to leave. He quickly heard footsteps coming up to him, and saw the president running up to him. "What's up?" he asked with a raised eyebrow.

To his surprise, the bespectacled president bowed. "Your club can stay. Consider it an apology for that coach's shadiness."

The pink haired young man smiled. "Heh. You're not that bad."

"But please make sure you submit your activity reports from now on!"

"Yeah, sure. Can I go now?"

The President gave him a curious look. "Uh, sure. What for?"

"His grandfather. He wants to visit him," Sasaki said as she approached the pair.

"You coming today?" The pink haired teen asked, to which the brunette nodded. "Okay! Get on then, Secchan." The girl responded by jumping on his back, Yuji's hands grabbing onto her wonderful thighs while the bespectacled girl wrapped her arms around his chest.

"Onward!" the brunette exclaimed.

"Hold on tight!" The pink haired teen warned before he began to dash outside the school with his girlfriend in tow. As he did so, he passed by a teen with spiky black hair.

"Hey, you!" The boy yelled trying to get his attention. However, Itadori ignored him and was long gone.


"Hey Yuji, Sasaki-chan." An old man with thin white eyebrows and white hair greeted from his hospital bed. Judging from his appearance, he didn't have much time left on this Earth.

"Hey Jii-chan." The pink haired teen waved with a grin. His expression betrayed the true emotions inside him, but he had been expecting this day for a while. His girlfriend put a hand on his back, giving him the best look of support she could give despite the situation.

"You two still going strong?" Yuji's grandpa asked with a knowing grin. "How long has it been, a year?"

Sasaki blushed. "Maybe a bit longer."

"Hehe, that's good." His expression became serious. "I assume you've heard the news."

The pink haired teen frowned. "That you could pass away within a day?"

"Mmm." The old man nodded. Silence permeated the room for a few moments before Yuji's grandpa broke it. "May I speak with my grandson?"

"Of course." The brunette nodded before giving her boyfriend a quick peck on the lips. "If you need me, I'll be right outside."

The pink haired teen smiled. "Thank you, Secchan." His girlfriend walked out of the room, leaving him alone with his grandfather for what may be the last time.

"Yuji, I have something to tell you. It's about your parents." Yuji's eyes widened in surprise. "They-"

"I don't care." The pink haired young man said curtly.

Yuji's grandfather blinked in surprise before trying again. "But…it's about your parents."

"Like I said, I don't care, Jii-chan." The young man sighed. "Stop trying to look cool before you die."

"No, you don't get it," said the old man seriously, "You need to hear this. Now shut up and listen, you little prick."

The young man blinked in shock. Only on rare occasions would his grandfather ever use that tone with him. He grumbled for a moment. "Alright, fine. What is it?"

The old man sighed. "When your father was with your mother…I didn't trust her at all."

"Huh? Why?"

"Oh, at first she was perfectly nice," admitted his grandfather nonchalantly, waving off his own words at the same time, "Sometime before you were born, though, she got in an accident. My son was so damn happy that she survived, without even having a miscarriage…but I could tell from the moment she came back from the hospital, something was different about her. Could feel it in my bones."

Yuji felt a chill run up his spine, and something in his gut turned over. "Different how?"

He grunted. "Hell if I know. It was like she started wearing a mask that looked and acted like her old self. That foolish son of mine ate it right up, but me? Nah, I could tell, and I could never get it outta my head. Didn't occur to me until after they both died…but it was like something was wearing her as the mask. And the way she'd look at you…" He shuddered. "It was like you were some kinda art piece, not her child. Like something she'd put time into making, and not the normal way. Even when they both died, I never felt like it was the end of things."

The pink haired teen shuddered, thinking back on everything that had happened to him up until this moment. 'I've always known that I'm not normal. Am I strong because of my mom? Is she responsible for that? I don't know whether to thank her or dig her out of the grave and yell at her.'

"Yuji." The dying man snapped the teen out of his thoughts. "I know it's a lot to take in…I just wanted you to know this before I left this world. A kid deserves to know about his folks, how they lived and died. Besides, " He gave his grandson a bright grin. "A man has to go out in style, right?"

Yuji huffed and shook his head. "And here I thought I didn't want you to look cool before you died."

"You can never beat a man's pride," his grandpa shot back, smirking, "Anything else you want to know before I croak?"

"Maybe some advice." Itadori muttered, just loud enough for his grandpa to hear.

"You want advice? Don't spend your money on flowers all the time! Save it!" The white haired man scolded.

"They're not for you, they're for the nurses!"

"Even more so then, you idiot! You trying to impress them or something? You got a girlfriend already!"

'Actually four, but he doesn't need to know that.'

"And," The old man began in a serious tone, causing his grandson to perk up. "Help people."

"Help people?"

The dying old man nodded. "You're strong, Yuji. Stronger than any of your peers. Use it to help people. Don't do it all the time, just whenever you can."

"But…I do that all the time. I help Iguchi and Secchan all the time."

"That's good. Keep doing that, and branch out where you can. Help people…" The man's face became solemn. "So that when it's your time to go, you don't end up like me." He grinned, "I mean, the only person who bothered to show up for my final days was my stupid grandson."

"Jii-chan…" The pink haired teen pouted. He looked towards the window as a frown formed on his face. 'Should I tell him about it? I don't have to worry about dying anymore…probably shouldn't mention that part though. He'd give me a lecture about how I should still be careful even if I'm immortal.' He smiled at that thought, before turning around to face his grandpa. "Hey, Jii-chan-" The young man's eyes widened in surprise, before quickly turning to sadness.

Lying there motionless and unmoving in his bed was Yuji's grandpa. He moved over to his side and brought out his arm to check his pulse. Nothing. The pink haired teen felt a rush of emotion overcome him as he went over to pick up the hospital phone.

"Hello Itadori-san, how may I help you?" The woman from the other side of the phone asked politely. "Itadori-san?"

The young man was overcome with a wave of emotion as he tried desperately to hold back his tears. "This is Yuji. Jii-chan is dead."

"…I'm so sorry for your loss. We'll come over there as soon as we can. You'll have to sign some documents before you leave, but take your time."

"Thank you." Yuji nodded, before hanging up. He remembered that Sasaki was outside the room too, so he sent a quick text to let her know what happened. After that…

Yuji: You wanna head into the lab before we leave?

Sasaki: Sure. Be right over.

Yuji: Thanks, Secchan.

He walked outside of the room, closing the door gently as he left his grandfather's corpse. He only had to wait a minute before he saw Sasaki running up to him before throwing her arms around him.

"I'm sorry, Yuji." She murmured as she nuzzled her head into his chest, while he hugged her back.

"Don't worry, I'll be okay." The teen insisted while a small smile creeped onto his face. "I can't just sit around moping." He flinched as he felt a pinch on his arm.

"That doesn't mean you should just sit around and put on a tough guy act." The brunette said sharply. "You got people who care about you. It's not good to hold your emotions in-Hey!"

Her speech was cut short as Yuji ruffled her hair. "Yeah, I get it. But really, I'll be okay. Jii-chan would agree with me. And when they burn his body, I'll laugh."

His girlfriend could only sweatdrop at that response. "Whatever you say…" Her expression became serious. "Let's go."

The young man nodded and held up his hand, a transparent key materializing in his fingers. Suddenly, a door that just missed the ceiling appeared in front of them. It was a blue, astral-looking door with a single keyhole and no doorknob. Yuji walked up to the door and used the key, unlocking it and pushing it open. "After you."

"What a gentleman~" Sasaki giggled, before walking into the door, Yuji close behind. Soon afterward, the door closed and disappeared.


The door led to a massive, dark passageway. The hall was mostly metal, but there were large globs of mass that could only be described as flesh in between the ceiling and floors. It was a sight the couple had long gotten used to. As they traversed the hallway, they came across an area with several different doors. They each had no knobs or even keys but seemed to come out of work from science fiction. There were even panels next to the doors, each with what appeared to be a hand scanner.

"Everytime I come here, I can't help but be excited and scared at the same time." Sasaki commented as she walked with him to one of the doors.

The pink haired teen shrugged. "It's not that bad once you get used to it. Besides, Lady, Yuna, and V will be happy to see you."

"I still can't believe our relationship is still going strong. Being in a relationship with one person is one thing, but three other people is another…let alone when the others are inside my man."

"But you love it that way." Yuji pointed out.

The brunette smiled. "Obviously. I'm just saying these relationships are hard to pull off, but we made it work." Her smile changed to a grin. "And I'd be dumb to pass up on three girls who are quite literally out of this world."

The pink haired teen laughed. He put his hand up to the scanner on the console, and the doors opened. Inside the room with the same metal/flesh look, there were a bunch of large consoles and screens as well. The entire room was also dark, and seemed to be empty, until…

"Welcome back, Yuji-kun, Setsuko!" Emerging from the shadows was a pale girl with short brown hair, like Sasaki. She was also around the same height as the other brunette as well, with teal green eyes, and wore a light gray jacket over a white shirt and black sweatpants. She was slightly bigger in the bust department in comparison to Sasaki, but Sasaki had the bigger lower body by a small margin.

"Yuna-chan!" The couple exclaimed as they rushed to hug their shared girlfriend. "Why's everything so dark?" Yuji asked.

"Take a guess?" The teal-eyed girl deadpanned.

"Boo!" A voice from behind them said. The trio turned around to see a girl with dark green hair with matching eyes. She wore a white sundress and on the back had glowing blue wings. She was almost like a fairy of some sort, except she had emerged from the red flesh in the room.

"Pasefu, that doesn't work on me anymore." Yuji said as he put up a finger.

"Right, like it didn't work the many, many times I had you shaking in your boots." The girl giggled. "Besides, you can't hate at least some normalcy on a day like today, right?"

"I guess not." The solemn look that appeared on his face spoke volumes.

"I'm sorry for your loss, Yuji-kun." Yuna murmured solemnly as she took one of his free hands into her own.

"It's a shame, but you knew it was coming for a while. So you were at least prepared for it." Persephone commented. "Besides, you did what Simon and I asked you to do, right?"

He nodded. "Yeah, I got it while I was talking to the nurse."

"Good, that means you can at least preserve his soul here, until the end of time." The eldritch fairy smiled, despite her ominous words. "So he'll always be with you."

"Thanks, Persephone." He scanned the room. "Hey, where is Lady and V?"

"Come to think of it, we haven't seen them, or even Squidface," Sasaki noted.

"Lady and V are in the Sorcery Archive. Simon's in the Void Armoire." Persephone informed them.

"Wanna come with us, Yuna?" The pink haired teen offered.

"Of course!" Yuna smiled, before joining her significant others out the door, and into the hallway.

"Guess we should visit Simon first since the Void thingy is closer," Yuji commented.

"Fine by me. I want to have another little contest with him at some point," Sasaki said with a grin.

"Are you actually gonna win this time?" Yuna teased with a Cheshire grin.

"Hey!" The bespectacled brunette pouted. "I can beat him one of these days."

"Of course you can, Secchan!" her boyfriend agreed with a much more sincere grin

"See, even Yuji agrees!" Sasaki pointed out.

"I'm just kidding. I think you can beat him one day too," the other brunette admitted.

"I know I can…" As they stood in front of the door, a nervous expression suddenly appeared on the bespectacled girl's face. "J-Just…not today."

"Thought so. You still need to train those powers more." Yuna advised.

"I've been getting better…it's just with school and stuff, it's hard to balance." She bore a guilty look. "Not to mention, making sure my parents don't know about it either."

The green eyed girl gave her an apologetic expression. "I'm sorry you have to hide stuff from your parents."

Sasaki let go of her boyfriend's other hand and smothered the girl in a hug. "Don't be sorry. I hate keeping stuff from my parents, but I don't know how they'd react to all…this. They don't need to know about it, and telling them the truth would only complicate things. Maybe later, but not now."

A smile appeared on Yuna's face from underneath the hug. "Thank you, Setsuko."

Yuji couldn't help but smile at the sight as his hand was scanned again to open the door. The door opened, and the group entered the Void Armoire. The chamber was lined with cybernetics and machinery lined up throughout the entire room. It had a station for making more tools as well, functioning as both an arsenal and a workshop. "Oi! Noire!"

"Greetings, Yuji." A figure emerged from the shadows of the Chamber. He was a gray squid-like creature. He wore a black button up shirt with matching pants and jacket. His lovecraftian appearance was complemented by orange eyes. Said eyes locked in on Sasaki. "I see you brought Setsuko as well."

"Ease up, Squidface. I'm not here to renew our rivalry today." Sasaki waved off.

"It seems you have finally realized you are outmatched."

A tick mark appeared on the bespectacled brunette's forehead. "No, I will kick your ass one day! Just today something more important came up!"

"I'm already aware." The squid monster said solemnly, before his eyes switched to Yuji. "I assume you did it?" The pink haired teen nodded. "Excellent. Now, is there anything else you wanted to discuss? I'm a little busy at the moment."

"Nah, we just wanted to visit. We'll leave you alone," promised Yuji.

"Very well." The squid nodded as the trio exited the room.

"Okay!" Yuiji exclaimed excitedly. "Let's see how Lady-chan and V-chan are doing!"

"You don't think they would be doing any activities without us?" Sasaki asked with a perverted grin.

Yuna shrugged. "I'd have thought so too, but they seemed adamant on wanting to learn more stuff from the archive." She deadpanned at her boyfriend. "At least someone is using it."

"Hey, I tried!" Yujui insisted. "It was all just so…confusing."

"We could help you." Sasaki offered before pausing. "Although, you seem to be more of the physical beast type of character than someone who would shoot magic all day."

"Who says physical beasts can't be versatile!" The pink haired teen exclaimed. "I wanna use magic too! Maybe I could finally live out my dream of using a Kamehameha! If Veldora could do it, then so can I!"

"I don't think the archives would have anything like that." Yuna said, shaking her head, before pausing. "But…they could have something similar to it."

"Exactly! My dream is still alive!"

"It's interesting how this place can make some of the things we only dreamed of possible." The bespectacled brunette commented.

"I know! Soon, I'll one day learn the Kamehameha Wave, and then the Rasengan!" He paused. "Hopefully I don't start spamming those moves too often."

"If you did, you'd be a real shonen protagonist." Sasaki teased. It was at this moment the trio finally arrived at the door to the Sorcery Archive. When Yuji scanned his hand again, the door opened to both a surprising but not unwelcome sight.

Two girls had begun to make out with each other on the metallic floor. The first had long green hair with heterochromatic eyes: one red, the other blue. She wore a white sweatshirt that did little to hide a plentiful bosom and white sweatpants. She had a round, firm, peach-shaped ass, and decently thick thighs. She was currently on top of the other girl, dominating her battle with ease.

Speaking of the girl under her, she had golden hair- literally metallic gold -with bangs that covered her eyes and two long braids on opposite sides. She was dressed in a white and gold blouse, with a large golden hood. She was absolutely thick, her skin seemingly carved from flawless porcelain. Her thighs were big enough to smother anyone who dared to get in between them, her breasts swelled dramatically, and her ass was an absolute dump truck that flattened and spilled out where she lay on the floor.

Both girls did not seem to pay attention to their surroundings as they were more focused on each other. As much as the trio would have wanted to continue watching the sight, someone had to let them know they had an audience. "Ahem." Sasaki coughed, a smirk appearing on her face.

The two girls flinched, before turning their attention to the newcomers, before their eyes lit up. "Yuji, Setsuko!" The green hair girl exclaimed as she ran up to the pair.

"V…I thought you were gonna just study from the Archive." Yuna sighed, shaking her head with an amused look.

The green haired girl blushed. "Well…we were. Then things just…happened."

Yuji chucked. "You two are insatiable sometimes."

The girl grinned, before pressing herself up against Yuji. "We could extend that to you guys. I don't know about Lady, but I'm feeling really hungry today."

"We would, but we came to visit you guys. I don't take it that you heard?" Sasaki asked.

"Heard what? We were pretty deep into our studies." V explained.

"Well…" Yuji explained his grandfather's untimely passing. The next thing he knew, he was wrapped in a tight hug by the young woman in gold.

Lady rolled her shoulders, at least three golden eyes narrowing under her bangs as she considered what words to use. "G'dhn mah, oroftua, [Yuji]." Her words, when they finally emerged, rolled and rippled through the atmosphere and made everyone besides Yuji flinch slightly as their meaning hammered into their brains.

"Thanks, Lady." He said as he returned the hug. He gave her a cheerful smile. "And I see you're getting better at Japanese."

The plushly-curved young woman odd golden darkening of her porcelain cheeks, before letting go and averting her eyes from him. "Madanaka…[Desire] [Learn] [Worthiness] [Yuji] [Primary Concubine]."

Sasaki snorted, knowing that the being was referring to her with that last burst of garbled human speech.

"We were working on her Japanese as well while we were here." V said as she brought Yuji into a hug of her own. "And…is there anything we can do to help you?"

The young man shook his head. "I'll be okay. Besides, I'm not alone. I have you guys with me."

"Yep, and you're gonna have to pry us off if you ever decide to hide your problems from us." Sasaki said with a grin.

"Well, we should probably get going. I have to sign some papers and arrange the funeral. We'll be back later though."

"We'll see you then Yuji, Setsuko." V said with a smile.

"[Parting]."


"Okay, just sign here." The nurse said pointing at the Certificate of Death, which Yuji immediately signed. "Again, sorry for your loss." She bowed.

"Thank you." The pink haired teen nodded as he began to leave the front desk.

"My parents are fine with me staying the night." Sasaki said with a smile. "They also told me to give you their condolences."

Yuji smiled back. "Ah, thanks. Y'can tell 'em I appreciate it."

"Itadori Yuji, correct?" A voice called out, causing the couple to turn their eyes towards the source. He had spiky black hair and dark blue eyes. He wore a navy blue jacket and matching pants. Something inside of Yuji told him that this young man was not normal. "I'm from Jujutsu College. Sorry, but there's no time. The Cursed Object you have is extremely dangerous. Hand it over."

"Hold on one second!" Sasaki exclaimed with a glare on her face. "My boyfriend just lost his grandfather less than an hour ago. You better have a good explanation for walking up to him like this and going on about a Cursed Object, you emo wannabe!"

The black haired teen's brow furrowed. "Ah…sorry for your loss. But the fact is, a lot of people could get hurt if I don't retrieve it." He took out his phone and showed a picture of a box with some type of talisman inside of it. "You have this, right?"

"Oh yeah!" Yuji exclaimed. "I found that."

"How is it dangerous?" the brunette asked as she crossed her arms. "We've had it for a while and our club really likes it, so I'd like an explanation before we hand it over."

The black haired young man sighed. "Fine. I'm Fushiguro Megumi, and I'm a Jujutsu Sorcerer. Have you ever heard of Curses before?"

"Sure." The couple said at the same time.

"Nationally, over 10,000 people a year die because of unexplained deaths or go missing. Most of these are because of the negative energy that flows out of people, which creates a Curse."

"Okay." Sasaki said while Yuji nodded.

"You're too easily trusting of me. How do you know I'm not just spitting nonsense?" Megumi sighed, rubbing his forehead.

"This isn't out of the ordinary for us." Yuji shrugged.

"If we told you, you'd look at us like we've grown a second head." Sasaki added.

The black haired teen blinked. "...I'll ask later. Places like hospitals or schools are susceptible to receiving that energy as well."

"I knew it! School is a cesspool of negativity!" The pink haired teen cheered excitedly, causing his girlfriend to sputter.

The black haired Jujutsu Sorcerer glared at them. "As I was saying…Pain, regret, humiliation, those sorts of things…the more people dwell on bad memories, the more these places become receptive to those feelings. For that reason, a Cursed Object is often found at those places as a talisman." He turned to Yuji. "The object you found is such an item"

"But don't talismans usually seal what's inside of it? Why would it be dangerous now?" Sasaki questioned.

"You're right, a talisman is harmless enough normally." His eyes narrowed. "Until it starts to weaken after many years. Then it essentially changes form and starts attracting Curses. They want it because it contains an extreme amount of raw Cursed Energy, and eating it would make them far stronger. However, the Cursed Object carries its own will and may end up taking it over. I won't go into details, but this is the worst case scenario."

Yuji rubbed his chin. "Hmm. Maybe I should try eating it. My gut is probably way more secure than a talisman."

Megumi just stared at him. "Are you an idiot?"

"I'd listen to him if I were you." The brunette grinned. "He could actually keep that Object secure in his gut."

"So you're both idiots." The black haired teen sighed before putting out his hand. "Just hand it over before I get infected."

"We don't have it." said Yuji, shaking his head.

"What are you talking about? I can sense the Cursed Energy."

"See." The pink haired teen took out the container for the talisman in his pocket casually. He opened the lid, and to Megumi's horror, there wasn't anything inside the box.

"You're telling me I was chasing the residue from the Cursed Energy in the box?!" He said aloud in disbelief. "Then where is it?!"

Sasaki's eyes turned to horror. "We left it with Iguchi."

Yuji's eyes widened in panic. "That's right! We were gonna meet with him later to peel off the seal!"

"Where were you gonna meet him?!" Megumi demanded.

"The school!" The brunette replied.

"Then unless you want him to die, we have to move!"

"Come on!" Yuji urged, before running out of the hospital with his girlfriend and Megumi in tow.


"If Iguchi doesn't peel it off," Sasaki began as she dashed with the others to the school. "Then the curses shouldn't come to the school, right?"

"Normally, anyone without Cursed Energy wouldn't be able to remove it in the first place." Megumi explained. "But the seal is so old that it might as well be regular paper. It doesn't even have to be peeled off, it could be removed if it's sitting in someone's pocket and it gets disturbed at all."

"I haven't gotten a response from Iguchi!" Yuji called out as he looked over his phone.

"I haven't either." The brunette said grimly.

"The school shouldn't be too much farther!" Megumi exclaimed as they rounded a corner. Suddenly, the group came to a stop. The school was only a few feet away from them, but Yuji couldn't help but feel a dark and eerie pressure coming from the building. It felt similar to when he had first gone inside the Laboratorium.

"You two stay here." The Jujutsu Sorcerer ordered. "He's supposed to be in the club room, right? Where is it?"

"You think we're just going to sit here while our friend is in danger?" Sasaki asked with a raised eyebrow.

"We've been friends with him for years. We have to do something!" Yuji added.

"Stay here!" The black haired teen ordered them again, this time giving them a scary and fierce look in an attempt to get them to comply. "You two aren't Jujutsu Sorcerers. If you rushed inside, the situation would only get worse!"

"We can fight too!" Sasaki argued, her eyes glowing a bright blue, surprising the black haired teen.

"I don't know about all this Cursed Energy stuff, but…" The pink haired teen put out his hand. To the shock of the Jujutsu Sorcerer, he watched the hand transform into a blade, while the rest of his arm shifted into a completely metallic texture, colored black and with red glowing lines all over the arm. "I can fight too."

The black haired teen could only stare in disbelief. "What in the hell are you two?!"

"We told you we had our own secrets, didn't we? You just didn't pay attention." The brunette pointed out, her eyes still glowing.

"I was born like this. Took me a while to figure out how to use it, and I still don't really get everything I can do with it." The pink haired teen explained.

"Born with- What do you mean you were born with it?! No one is just born a cyborg!" The black haired teen argued.

"Hey, I don't know how it works either!" The pink haired teen said as he began walking up to the door. "But we don't have time for this!"

Megumi sighed. "Fine. But I'm going to need some answers after this. Sasaki, what can you do?"

"Oh, I have psychic powers! Yuji gave 'em to me," The brunette replied cheerfully.

The black haired teen just stared at Yuji. "I'm really gonna need some answers. Come on!" The trio rushed into the school, opening the door pretty quickly. As they entered the front door, they encountered some kind of abomination.

It was completely pitch black, standing on what appeared to be three toes. It had eyes all over its long body. It had a mouth at the top of its head. The monster was in the shape of a leg. "Slurp, slurp, slurp…" It muttered in a distorted voice.

"Ugh, gross! Is that a…?" Sasaki asked, her eyes widening in horror.

"A Cursed Spirit." Megumi nodded. The young man grit his teeth before folding his hands together. "You're in our way." He folded his hands together, making the shape of a dog. "Demon Dogs…" Black fluid started forming from the ground. Soon, the fluid took the shape of two dogs, one white and the other pitch black. "Go and feast!"

The dogs howled, dashing towards their prey. To the surprise of Yuji and Sasaki, the dogs both bit chunks out of the Curse's body, causing it to scream out in pain. Finally, it collapsed from the pain, before disintegrating in a blast of smoke.

"What are those things?" Yuji asked, curiously.

"They're my Shikigami." Megumi replied. "I noticed you can see them."

"Well yeah. They're right in front of us." Sasaki deadpanned.

"Normally, people can't see them unless they're facing death or in special places like this." The black haired young man explained. "Unless that's somehow in your bag of tricks too."

"Probably not." Yuji shrugged, "Never seen Curses before."

"Come on, let's keep going!" Sasaki urged as she rushed forward.

Suddenly, another curse appeared from around the corner. It was much more normal than the first one, appearing to be some type of chameleon, with large, reptilian, rounded and isolated eyes, webbed feet, and a tail.

"Out of our way!" The brunette's eyes glowed, and an invisible wave of energy struck the Curse. The chameleon's midsection bent unnaturally, the reptilian-like curse crying out in pain. To the shock of Megumi, the curse seemed to start disintegrating like the first curse did.

"At this point, I'm just gonna stop questioning everything." said Megumi as he rubbed his head.

"Come on slowpoke, you're gonna be left behind!" Yuji shouted as he ran after his girlfriend.

"Please let this be over soon."


The trio made it to the highest floor of the school. They had each eliminated curses along the way, but they still hadn't been able to find Iguchi.

"He has to be up here somewhere!" Yuji declared as they started to round a corner. As they made it around the corner, they all stopped in their tracks.

Down the other side of the hall, there was a curse in the shape of a massive blob with three spider-like legs. It had two hands, two large eyes, and long black hair. On top of it were smaller worm-like curses with many eyes. In the center of the blob, was Sasaki and Yuji's best friend, Iguchi. He seemed to be sinking into the curse, almost like it was trying to swallow him.

"Damn it, we're too late!" Megumi cursed.

"Not on our watch!" Sasaki's eyes glowed blue again, and the curse down the hall cried out in pain, while Iguchi was being pulled out of the monster's body. The creature was getting crushed by the pressure the brunette was putting on it, as an attempt to get it to spit its meal out. Finally, the young man was ripped out, the blob splattering onto the floor as Iguchi was pulled to the other side of the hallway, safely away from the Curses. "Yuji!"

"Got it!" The pink haired teen ignored the cries of pain from the blob curse, as his arm morphed once more, growling slightly longer this time. It was the same black cybernetic arm with red lines, but at the end this time was a scythe with two red blades conjoined together. He rushed the curse, slicing the already wounded area of the curse while cutting off both of its hands. He shifted his attention to the smaller curses, before he made a slight movement with his scythe. In an instant, all the smaller curses were cut in half, before disintegrating into smoke. Then, he sliced the groaning blob once more, cutting it cleanly in half this time, letting it join its fellow fallen curses.

"Nice job, Yuji!" his girlfriend cheered as she assessed their friend. The young man was unconscious, but did not appear to have any other external injuries. She began to search him for the Cursed Object, before finally pulling something out of Iguchi's pocket. "A finger?" the girl said herself, grimacing at the macabre, severed appendage. It couldn't be a human finger either; it was FAR too large, with a fingernail more like a talon or claw.

"Special Grade Cursed Object, Ryomen Sukuna." Megumi explained as Yuji walked up to them. "That finger is only a part of it."

"There's more than one of these?" Sasaki asked with wide eyes.

"Ryo…?" Her boyfriend meanwhile was having trouble comprehending the name of the finger.

"Forget it. Just hand it over." The jujutsu sorcerer demanded as he put out his hand.

"Secchan, look out!" Yuji pointed at the ceiling, causing his girlfriend to look up. A massive hand was emerging from the ceiling, reaching for the girl. It was coming down so quickly she didn't seem to have time to react. He jumped in, shoving her out of the way as they slid across the floor together. A loud crash was heard, followed by a thud as smoke burst from where the monster had come from. He looked around and saw Iguchi had been dragged to them by one of the dogs.

"Nice save." Sasaki said with a smile, petting the dog's head. It blinked at her, its tail wagging slightly.

The pink haired teen got up and helped his girlfriend onto her feet. "Where's Fushiguro?" he wondered.

His answer was given to him in the form of the black haired teen being grabbed by yet another new curse. This one was far larger than the blob, stretching nearly the entire width of the hallway. It was tall too, about as tall as the whole floor. It had six legs, two of which were hind legs that it used to run, while the other four were like hands. It had two red eyes on each side of its head, a tail, and a face in the shape of a fish from the abyss. Finally, it had swamp green hair that grew from its back down to the base of its tail.

One of Megumi's other dogs tried to bite at it, but was promptly smacked away by a free hand. "Damn it." The black haired Sorcerer cursed. He put his hands together, forming a shadow puppet of a bird. "Nue…!" The chant was interrupted, as the fish-like abomination shook the teen, then quickly began to slam the jujutsu sorcerer against the wall. Before the blow could land, however, the creature stopped abruptly, as if something had grabbed hold of its arm and held it in place, making it strain futilely to escape. The creature twisted its head around to see what had a hold of it, and saw Sasaki glaring intently at it, her eyes aglow.

"Slow down there, fishhead." The bespectacled brunette said with a tight grin. Her boyfriend rushed at the hulking Curse, quickly closing the distance, and slashed the free arm it had used to try to block. The limb sliced off cleanly like it was butter, causing the spirit to squeal from the pain, before using its other hand to smack the weaponized teen away. Yuji didn't expect the Curse to be so strong, as he was sent flying back towards his girlfriend, colliding with her and spilling onto the ground.

"You alright?" he asked her as he quickly got up.

"Yeah," she huffed, rubbing her head, "But I don't think Fushiguro is."

The pink haired teen's head turned back, and saw there was a new hole on the right side of the hallway. They also noticed the dog near Iguchi was melting away, fading into insubstantial shadows. "Shit!" The couple left their friend near the safety of the lockers before rushing towards the hole to help Megumi.

They saw him just staggering to his feet from the top of the roof of the corridor, while the Curse just stared him down. It began slowly crawling towards its prey, while the black haired young man tried to summon another shadow again. Just when the fish abomination was ready to pounce, however, another force knocked it back into one of the main school buildings, slamming it against the hard concrete. Still feeling shaky, Megumi looked up to see Yuji jumping down onto the roof while Sasaki floated down with a blue aura around her.

"Any ideas on how to deal with this?" The brunette asked as her feet finally touched the roof.

"We'll be dealing with more like them as long as that finger is around," the Jujutsu Sorcerer informed them, "Even if we take this one down, more will take their place. We'll be fighting an endless battle."

"So we just gotta seal the finger back up somehow, right?" Yuji asked.

"Yeah, but that'll take time." The black haired teen refuted.

"Don't worry, I got a plan. Secchan!"

"Got it." The brunette grabbed the finger from under her sweater vest and tossed it to her boyfriend, who caught it easily.

"What are you doing?" Megumi asked.

"Keeping it nice and secure in my stomach!" The pink haired teen then opened his mouth and began to put the finger inside of it.

"Are you an idiot?!" The black haired teen made a move to stop him, but was stopped by Sasaki as he was held in place by her telekinetic force. "What are you doing?! Your boyfriend is about to ingest a special-grade cursed object! It's basically a lethal poison!"

"Yuji-kun is immune to poison." Sasaki rebuked.

The Jujutsu Sorcerer's eyes widened in surprise. "B-But, there's still the one in a million chance it will incarnate inside him! He could be possessed!"

"I wouldn't worry about that." The girl's face twisted into a manic grin. "If that happened, that Sukuna guy would be the least terrifying thing inside of him!"

Their attention went back to the pink haired young man in question, as he readied his scythe. The Fish curse charged at him then leaped, its jaw open and ready to bite the teen's head off. Yuji smirked, as he sidestepped the curse, the monster missing his head by a couple inches. Before the curse could retaliate, Yuji slashed one of the Curse's hind legs, leaving the monster's mobility crippled. As it howled from the loss of its leg, the weaponized teen stabbed the curse's side, then dragged it along its body, making the wound far larger. Once he reached the tail, he finally pulled it out, just in time for the curse to collapse into a heaping pile of smoke.

"Well done, Yuji-kun!" Sasaki said excitedly as she ran up to her boyfriend. Her boyfriend picked her up by her waist and spun her around, much to the delight of the bespectacled brunette.

"Ahem." Megumi coughed, interrupting the celebration. "As much as I hate raining on this parade, what happened with the object?"

"Oh, the spirit has been contained." The pink haired teen answered innocently, "I think it tried to take over, though."

The black haired teen's eyes became as large as a bug's. "It tried? You suppressed it?"

"Sort of." Yuji shrugged. "I have a Holding Cell inside of me. It's impossible for anyone to get out of there if I don't want them to. Oh, and is this what Cursed Energy is like?" He held up his hand, which began to emit the typical blue and black aura of sorcery. "It's kinda neat."

The Jujutsu Sorcerer's mind looked like it was about to explode. "So from what I can gather…Sukuna is locked up inside of you now?" The couple nodded. "What if he escapes?"

"He won't. Even if he gets out of the Cell, there's others that'll keep him in line." Yuji answered.

"Others?"


Inside the Laboratorium of Yuji, there lay a dimly lit chamber, with a similar exterior to the rest of the dimension, except this one had several large red colored tubes littered across the room. Each tube looked large enough to hold at least several people at once. Up until now, this room had remained largely unoccupied, for Yuji had had no interest in containing any of the eldritch organ's inhabitants.

"What is this place?" sitting at the bottom of one of the tubes was a young man with a similar appearance to Yuji. However, he wore a white kimono and his pink hair was slicked back. Black markings decorated his face and body, including black bands on his arms reminiscent of the tattoos given to criminals in a more feudal era of Japan. He rubbed his chin, his nails blackened, four eyes narrowed in mild consternation, yet unconcerned. "Strange. I've regained consciousness, clearly, but this doesn't feel like the normal world. Shouldn't I have been incarnated by now? Don't tell me they thought they could contain my vessel…whoever 'they' are, that is."

"Mof'ulra rugn burkrahth. Herongi, maftal'bi rushbua batana, [Ryomen Sukuna]." An incomprehensible string of words stabbed through his brain, making him wince despite himself and grit his teeth in irritation. Standing a few feet from his prison was the Lady, her stare boring into the prisoner as she idly twirled a golden umbrella. All around her, a tide of black rippled and flowed around her dainty feet, churning and bubbling with golden eyes.

"It's been a long time since someone could irritate me just from the sound of their voice." The prisoner commented casually, before smirking. "What are you? If things like you exist, then the world has become more interesting since my death."

The man was surprised by the sadistic grin that formed on the inhuman girl's face. "T'mal'tri? Mkhi, da ahkha medet rufkin jhing," she agreed, shrugging. The black fluid and eyes spread out, flowing up the walls to cover everything and glare imperiously down at Sukuna.

The King of Curses chuckled, even as his killing intent rose. With a swing of a clawed hand, several clean slashes sliced through her porcelain flesh like tofu, revealing more bubbling, oily blackness and eyes, though her body remained standing. He ignored the fact that the material that composed his prison was completely unaffected. "As I thought, you're not human in the slightest! Whatever you are, I'm going to look forward to seeing what you taste like." Sukuna's chuckle escalated to a full laugh of excitement…

Only for him to stop when the woman whose upper body he'd sliced into thin layers chuckled along with him, her flesh and clothes pressing back together and reforming seamlessly. She picked up her umbrella and slung it over her shoulder, giving him an almost flirtatious smirk.

"[Then] [Partake]," said the Lady-in-Gold, curtseying.

Although he had only just met this inhuman being, Sukuna's skin crawled at hearing a close approximation of human speech coming from her. His lips peeled back in a maniacal grin. "GLADLY!"

End Chapter


Been a minute eh? Let's just say I've been working on a lot of projects. This is one of them. Yuji with the Laboratorium is the second of what I dub "The Eldritch Trio." Yes, I will have one more story with this CYOA, because I can only get three stories out of it. What's the third one? You'll find out when it drops. As for this story, obviously a harem, and I'd like to thank NSG for the help with Lady's Dialogue. A bunch of you might be surprised I chose Sasaki over someone like Yuko to be his first human girlfriend, and that came down to two things: Who could I buy being involved in Yuji's life more, including helping Yuji fight as a Jujutsu Sorcerer. I gave the edge to Sasaki because of how much she's into the paranormal and occult stuff. The second was who wore glasses. Yeah, Yuko never stood a chance. Don't worry, I ain't cruel, she's got someone for herself. Also, I decided to make Yuji, Sasaki, and Iguchi have more history together, and be around the same age and in their third year together. This is because how irrelevant Sasaki and Iguchi being a year older than Yuji is, especially since he barely interacts with them anymore. Only thing that matters in terms of who's older than who is when Jujutsu College comes into the picture. Hope you all enjoyed the first chapter, see you all whenever chapter 2 drops.
