Partner

*Bang! *Bang!*

Within a training room, a shirtless silver haired youth was fiercely throwing some sick punch kick combos unto a punching bag.

His eyes were blindfolded, and his knuckles were taped. His slim figure was packed with lean muscle, and his visage could only be described as incredibly handsome.

Even after reaching what could be said to be the pinnacle of mortal strength with just his physical body and reaching a nigh untouchable and unbeatable level of strength in this world, this young man had still never given up in his work ethic.

Call it a waste of time, but deep down inside of that youth was a fire that burnt and the zeal to strive for perfection and to be the best.

After a few minutes of continuous training, he unleashed a spinning back kick which hurled the punching bag flying to the other end of the training room like a meteor.

He took a deep breath and picked up a towel and a blue bottle, before he downed its contents quickly and wiped himself of the sweat.

He sighed after letting his mind wander through thoughts before taking a seat on a stone slab.

'After learning blue, my progress with the Limitless has probably reached another bottleneck. The next stage is to master reverse cursed technique in order to be able to use red, but the thing is, Ive been trying to go according to what was written, but it's just not working.' He thought for a while and decided to try his luck once more.

He slowly took off the blindfold, revealing a pair of piercing azure gem like eyes, and adjusted his breath for a moment.

'Multiply negative with negative...multiply negative with negative...' He calmed himself and began to slowly gather negative energy within his palms.

The reverse cursed technique was a technique which allowed one to create positive energy by just multiplying negative energy with negative energy.

'Multiply negative with negative...' Gathering one portion of negative energy on his right palm and another on his left, he slowly brought them together, trying to get the reddish flame like energy to multiply itself.

*BANG!*

The next moment, the energy between his palms exploded, hurling him into a pillar, as his body slowly fell to the ground.

"Fuck!!" He sat up and cursed out, before rubbing his shoulders which were currently in pain. 'Multiply negative by negative?!...multiply negative by negative...' He slowly calmed himself and tried repeating the process, trying to hypnotize himself with the chants, but inevitably, it exploded in his face once more, sending him flying again.

"Multiply negative by negative?!!! What does that even mean?!" He roared in confusion and lied on his back with a sigh. After failing for probably the gazilionth time, he was starting to feel exhausted.

According to the Jujutsu Kaisen anime or from what he watched at least, he learnt that reverse cursed technique was just multiplying negative energy by itself to create positive energy. As for how you were to multiply a form of energy by itself, he didn't know, or whether a catalyst was needed, or whether the amount of energy he needed had to be in a certain amount he had no idea, or whether said energy had to be in two different proportions in order to multiply.

All these were variables that should be considered when trying something nigh impossible such as trying to multiply a form of energy by itself. It wasn't called one of the most advanced techniques in the Jujutsu Kaisen franchise for nothing. At the very least, he trusted that since some characters had been able to learn the technique, there was hope for him to learn it as well. The only problem was he didn't know how long it will take or whether he needed to achieve another enlightenment, or whether he would have to touch on the core of cursed energy itself.

'Man I should've watched and read everything there was to know about the Jujutsu Kaisen universe before dying..' He facepalmed and sighed, but a small smile formed on his face, as he remembered something.

"At the very least, Ive made some progress of instant teleportation." He laughed and interlocked his fingers in an intricate seal.

"Okay, Okay, let's see if I can bring the theory into reality. I hope this doesn't turn into another RCT moment for me." He chuckled to himself and steadied the rhythm of his breath.

Instant teleportation quite complex in its own right, although having a basic understanding of the Limitless and six eyes made it a bit less strenuous.

It was a simple technique which involved collapsing the space between himself and his destination using negative energy, neutralizing the very concept of distance.

In other words, teleporting according to the Limitless worked in the same way as Blue, which involved spatial distortion. Even through his research, he found out that, even in reality, when space time is distorted, a gravitational pull manifests which begins to pull objects into itself to try to mend the distorted void.

Teleportation according to Limitless wasn't a form of instant movement, but by warping space, the very concept of distance becomes neutralized, creating the illusion of instantaneous movement.

"Okay, here it goes!" He took a deep breath, materialized huge amounts of cursed energy and just as he was about to execute the technique, he stopped and clapped himself on the head.

'How could I forget a destination!! Seriously Satoru what the hell is wrong with you?!!' He sighed and shook his head before he interlocked his fingers once more, materialized massive amounts of cursed energy, and this time, he used the six eyes to pinpoint a destination which was his bedroom.

*CLAP!**BANG!*

The sound of his palms hitting each other reverberated, as his body disappeared in a split second, leaving only the floor where he previously sat cratered.

"Did it-wo...It fucking worked Hahahaha!!!!" Slowly opening his eyes, he found himself on top of his bed, as he laughed without reservation. "Let's do it again!!" He smiled and interlocked his fingers and clapped his palms once more and his body mysteriously disappeared and reappeared in his bathroom.

From the bathroom, to the living room, to the training room, back to the bathroom then to the bedroom.

He practiced his newly formed ability until he was mentally exhausted. "Bzzzt! Bzzzt!" After a few moments, his phone which silently lay on table beside his bed began to vibrate, as he took it and picked up the incoming call.

"Satoru! Where have you been?! I've called you several times now, but no answer..."

Aki's voice resounded on the other side, as he listened with a bored expression.

"What do you want?" He said with a tired voice. "Ms. Makima has requested for your presence to debrief you on the mission. Your partner is already in and did you forget that you have a mission tomorrow?" Satoru couldn't help but sigh, unwilling to listen to Aki's rants, as he ended the call swiftly and teleported to the the bathroom.

.

Within Makima's office, a handsome youth dressed in a three piece suit with long blonde hair sat on the couch along with Aki. His face was expressionless, and the most peculiar thing about him was the pair of white fluffy wings which grew on his back.

Makima sat opposite them, going through some paper work when she felt a familiar negative energy source reappear out of nowhere in front of her office.

"Oh?" She couldn't help but raise an eyebrow, as she watched the silver haired youth with the white blindfold dressed in his signature long necked jacket, trousers and shoes walk in, in an arrogant fashion without even knocking.

Satoru sat on a different couch, while his gaze peered towards the blonde haired youth with the wings before mere seconds before retracting his gaze.

"You're late." Makima raised an eyebrow, while he shrugged. "I had an emergency, you know. My uhh dog ate my uhh keys.."

"But you don't have a dog..."

Aki was quick to sell out, as Satoru glanced at him and rolled his eyes under his blindfold.

"Good point.." He smiled a moment later, as Aki sighed and shook his head.

"Anyway, Satoru, this is your partner, the Angel devil...but you can call him Angel.." She introduced them, as Satoru nodded towards the silent youth with the wings.

"So you're the angel devil, and your name is Angel?" He asked as the youth nodded. "Interesting..."

A/N: Another chapter, because why the hell not. Also anyone with ideas on RCT should let me know in the comments, Gracias.
