Considering Sakura Haruno's proficiency in the field of medical ninjutsu, it's no surprise that an eye transplant-- of two eyes, mind you-- that would've taken several minutes, only took a few seconds of her time to accomplish. With little to no effort, the pinkette successfully switched Sasuke's Mangekyou Sharingan with Kakashi's, which effectively left the Uchiha with the Rinnegan and the Kamui dimension, whilst their teacher was left with the Amaterasu.

For the first time in years, Obito's left eye returned back to its original dark shade the moment its nerves connected with Sasuke's sockets.

"How does it feel to have Kakashi-sensei's eye?" Naruto asked with intrigued curiosity, as he intensely stared at the newly implanted organ on his teammate's socket.

"Like having an eye, dobe," Sasuke playfully teased with that familiar smirk they all knew since their academy days.

"Y'know what I'm talking about, Sasuke-teme!"

Sakura was tempted to leave the two's bickering be, as it was a nice throwback to what their genin team was once like, but seeing your and Kakashi's bodies from her line of vision snuffed that desire out, and opted to have her make Sasuke and Naruto focus back towards the goal at hand.

"So, what now? We still have yet to figure out how Kakashi-sensei managed to separate his and (Y/n)-sensei's Yin chakra from their bodies," The medic reminded, as the blond and noiret finally registered that they have no plan how to proceed. They were just mainly relying on Sasuke's limited knowledge the whole time.

The Uchiha pondered for a bit, before being forced to speak by the deafening silence within the hospital room (it honestly feels pressuring).

"I'll activate it first, and then I'll try to experiment with it. I'll see what I can do from there," Sasuke managed to utter out from his contemplation, unable to admit that what they ask of him may be too difficult. Then again...

What is an Uchiha without narrow-mindedness and the love for a challenge, after all?

Plus, his special people's lives' are at stake here, only encouraging him further.

"It's best if people I trust would supervise me while I do so," Sakura's heart warmed at Sasuke's implication of his trust towards them while giving them the look of camaraderie, despite everything. It's comical to think that this is the same person that tried to kill her and Naruto more than once. They were glad they managed to free him from his clan's curse of insanity and hatred.

Nevertheless, the room is filled with people Sasuke can rely on: Sakura, Naruto, and Tsunade (there's you and Kakashi but you're both out of commission as of now, and Ino left earlier to attend clan duties; Shizune is meanwhile already gathering textbooks and scrolls that could be of use for further research).

"It's best if Ino were to supervise with us. Playing with Yin chakra is no joke, and the misuse of it can incapacitate you, as much it did with your two instructors," Tsunade warned, as Sasuke only nodded in agreement. "I should also add that the use of your experiment is only to confirm theories and to help study the procedure if it were to end up being successful; not yet to save them. We may only worsen the situation, as we are not familiar with this part of the sharingan's capabilities, granted that this is the first."

Just as Sasuke was about to incline his head to accept the given terms, his right eye-- the newly-implanted eye-- started to throb; at first it was tolerable, but then it started burning.

Wincing, the Uchiha cupped his right eye socket as his feeble attempt to numb the pain, while his company gave him a concerned stare. Sakura was just about to ask if her operation was faulty (which she can't help but feel bitter about if that were the case), when the familiar Kamui portal started consuming Sasuke's body-- his left eye being the epicenter-- which at a dumb split-second decision, Naruto and Sakura decided to grab any part of Sasuke to be part of the consumption.

It all happened too fast that none of them were able to process what happened until it ended.

And then, Tsunade was left on her own, with her two jounins still at their beds-- motionless, whilst having three more of Konohagakure's greatest assets unavailable.

"... Fuck."

Kakashi Hatake is stressed.

It may not seem like it, but he's only an anxiety away from a mental breakdown-- his usual placid expression (and face mask) covering it all. It's one thing to be transported into an unfamiliar other world with different laws and culture; another to share a weak body with a brat; his chakra's usage being limited to only body enhancers (which is more taxing than it usually is); but having no Icha Icha Paradise equivalent in this dimension is where he draws the line!

Fifty Shades of Red was anything but that. At first, he thought it was, due to its popularity that rivals Jiraiya's works, but boy when he finished the book, not only was he wrong, but to have such a book to be popular, he concluded that a lot of people in this world are either closet sadists or masochists. The book was only good for repelling social interactions and to feign ignorance at this point.

BDSM was not Kakashi's cup of tea when it comes to his por-- erotic literature. He's the vanilla type. While he's okay with a lot of kinks presented in the Icha Icha series, it was still done with passion (both in the work itself and its interesting scenes) accompanied with an engaging plot (which made him read it in the first place). Fifty Shades of Red was amateur at best in comparison to his favorite novel series-- it was more of an outlet for the author rather than a work of art.

That may be his bias though, because as a seasoned shinobi, he would really prefer to separate weapons and interrogation equipment from his fantasy bedroom life. Kakashi is no sadist. He's no masochist either (wanting to drop dead does not count).

At least in his old world, people weren't really secretive of that part of their personality, but he concluded that the strict laws do prevent people here from doing more than half of what shinobi can. Plus, social norms are heavily encouraged in this world. Kakashi is pretty sure he already broke a handful of laws unintentionally.

On the bright side in all of this chaotic mess, you are with him. Princess of Infiltration Missions (second only to the best honeypot: Kurenai Yuhi); Queen of Intelligence Gathering; Brain of the Pair (Honestly, the Hatake and Uchiha only share one braincell and the Uchiha owns it most of the time); the Walking Encyclopedia-- local monikers that point out that: oh my Kami, Kakashi Hatake is lucky that of all people he could be stuck here with, it was you!

Don't get him wrong, he does infiltration and information gathering at times (it's a basic shinobi skill. Though, it's not even the main mission, he does it just to find the target's location; it pales in comparison on your type of infiltration missions), but he's the assassination type of guy, y'know? People are hard; emotions are hard, and as much as he hates to admit it, his social life is close to non-existent (you once told him that he has the personality of an ice cube: square, cold and literally has no social life. He'd rather die before he'd admit that he was 'slightly' offended).

Although, with assassinations, you don't have to get to know your target; you just have to know how to kill them-- no closure needed.

In this world full of foreign norms and unfamiliar rules, however, social life and connections are a must. You are the best adapter of the pair, because this world is... peaceful. This world condemns the concept of killing and is accepted as a major crime. Between the two of you, your specialization is more needed.

This laws in this world is humane that way.

And you're the most human shinobi Kakashi knows; a pacifist who actually lives up to her ideals and does not kill unnecessarily (as long as you can incapacitate the enemy, you will-- Kakashi will do the rest). You don't self-destruct when you're stressed, and instead you become even more productive than usual; hence, earning you more achievements within the village. You're not an emotional maze like Kakashi is, and you actually tell people if you don't feel like socializing, instead of forcing yourself to get along and only appearing more of an aloof asshole.

That's not an easy feat, just so you know.

The whole point is: you're reliable.

Despite you having a peaceful conscience, paranoia is second-nature to a life subjected to countless enemies and killing. Granted, the Fourth Shinobi War paved way to a future of peace, anxiety is less of an illness but more of a habit that would have to die hard at this point; ingrained in your heads until death-- your past traumas do not help your cases.

Basically, excessively worrying became every shinobi's defense-mechanism-- it either does its job right or you die from worrying too much. It's a win-win, in Kakashi's opinion.

A doubtless shinobi is a dead shinobi.

And so, here he is.

Today's activity was supposedly simple; rescue training was something he was all too familiar with, mainly because that's part of his job as Konoha's loyal (dog) shinobi. However, after his and your encounter with a foreign Killing Intent, he knew that he couldn't let his guard down and should expect the worst. Until he finds this world's enemies actually threatening, the use of chakra would have to stay on hold, as you instructed. It was only to be used for life or death emergencies. He has yet to see what this world is really capable of.

Still, no matter the universe, the dimension-- as long as the ability to kill exists, Killing Intent is bound to co-exist with it.

This world of heroes is no exception.

Looking at you, Kakashi observed as you studoed the new instructor that he couldn't care less about (though, he is a bit interested in the teacher's Black Hole quirk, but not enough to be invested). He can't remember the last time he stood still by your side, and really looked at you. Not much has changed through the years since you've been on duty. However, your pre-academy self was a different topic-- you used to be so expressive; much like the teen you share your subconscious with.

Speaking of subconscious...

'Man, I wish someone would look at me the way you look at her.'

This invader of his privacy is such a nuisance that he doesn't want to deal with right now-- or ever, for that matter. He found it funny that the pinkette and the blond you're both inhabiting resembles two of your students, and their similarities with their personalities were uncanny.

It became a routine for Kaminari to usually tease Kakashi about you, as you are literally the only leverage the blond has towards the ever-so-aloof Hatake. Kaminari would pester the man to day's end, but not receive a reply back, but any mention of you would have Kakashi respond immediately-- whether positive or negative; it's still a reaction.

'You mean my look laced in protectiveness, and on-guard due to our abnormal circumstances that we've yet to solve and thus in the meanwhile we can only revel in our thoughts of anxiety and paranoia? Weird desire, but I won't judge.' Kakashi quipped with such heavy sarcasm, Kaminari took a long moment to pause before only uttering out:

'... That's cold, man.'

The jounin swore he lost five years of his lifespan from that comment (fuck, Kaminari only supported your ice cube insult).

Kakashi will admit, having a roommate in the head is a lot more difficult than it sounds; especially that he values his privacy. It was only thanks to his ANBU training that he can control his thought processing in case he were caught in a situation that there would be a mind-reader in the enemy side that could easily extract information from him; hence, he can control what he thinks (the problem is that it's so exhausting, and even as a professional shinobi, he can't help but slip up a few times).

How the hell does Naruto live with the kyuubi inside of him?

Then again, the Uzumaki is an open book and probably doesn't mind sharing his thoughts with a conscious chakra battery that saved his life more than once.

... And Kurama doesn't have an over-bearing personality either, unlike who Kakashi is stuck with.

Is this his personal hell? His karma? A sick punishment of some sort?

Looking at you once again, Kakashi grounded himself back to his current predicament-- in a field trip within some facility, supposedly listening to the teacher's speech about responsibility of quirks or something of the likes.

Presence of mind is a must, especially that he expects something to happen at any time-- either during or after school, he has yet to know. Whether or not it would affect his class is also unknown.

He shouldn't be caught off-guard.

It happened to him once with his father. Then with Obito. With Rin... His sensei.

So much losses. Racked with grief and guilt.

Kakashi's friends are outnumbered by the dead.

You won't be next, he swore. Kakashi will break his streak of failures.

You are his mission that lasts a lifetime; his top priority.

You're a promise he intends to keep this time.

~*~*~

I decided to cut this arc in two/three chapters, because the last time I overdid it, the site deleted all my progress and i cried. SO, I'll focus on this book until I finish the USJ arc.

Just so yall know, this book is my subconscious' shenanigans; the epitome of my stupidity; partnered with my writing skills that rival a first grader's. I once repeated grade school level english twice thats why im so eloquently spoken motherfucker (thats honestly what kaminari would say also that was a lie pls dont think im an actual idiot asfghjkkl (fuck thats exactly what an actual idiot would say))

Ngl, I struggled with this chapter (it actually kicked my ass) because I need Kakashi's POV transition to understand his way of thinking and what he prioritizes before we move on to the fight scenes. Still, I'm slowly unraveling what your dynamic with Kakashi is like. Tbh, a lot of sacrifices were involved, and your relationship with him is a lot deeper than what I originally intended fucc

AND YES, THE ORIGINAL TEAM 7 HAS JOINED THE CIRCUS

I might make a new book just to show your life in Konoha-- from childhood to where you are now. It's just a side-project tho-- not consistently plot heavy and you dont necessarily have to read it to understand the plot here. It's like a book of one-shots that only feature the highlighted parts of your life and maybe some kakashi oneshots too lmao

i will admit that one of my motivators to write that book is to call the third hokage out from his bullshit lmao like

Hiruzen: *hitting a bong*hey minato i will abandon your son, the moment you entrusted his life to me after you die. do you hear that minato? are you rolling in your grave now minato?? are you the fastest grave roller now minato??? must be a fucKING ROLLERCOASTER--

Also, love interests have been updated, we now have: Aizawa, Kakashi, Hawks, and Dabi.

Chisaki doesn't deserve my attention after what he did to my sweetheart Eri and Mirio
