I don't own Naruto or LOTR. It's just me messing a bit with their works. Oh, and I'm not so sure about my skill in English so sorry for any bad grammar or mistakes. Also, keep in mind that It has been years since the last time I read LOTR and I was never an Tolkien expert sooo this will probably be U.A with a lot of things that don't match with canon (because I'm lazy as hell).
Her whole body is sore and her head felt a lot like that one time she decided to get drunk – with the oh so adorable squeaky crying of a baby in the background. Her eyes opened to a cloudy gray sky, the sudden change of scenery making her wary. The girl moved and sat down quickly, trying to process what in the seven hells had just happened. It occurred to her that either a) she was dead and that was the Purelands or b) she was in some genjutsu from that insane psychopath of a cousin.
Her hand instinctively gropes the spot where she's been perforated, which itches like hell but isn't gushing any more blood; she touches the raised skin tissue, like a scar that has been there for years. She frowns. She is confused, and studies her surroundings, though there isn't much to notice other than the huge amount of dry, ravaged land. There were mountains on the horizon, but it felt like an inhospitable place... uh.
Was that the katana Itachi stabbed in her chest?
Kana narrows her eyes and takes the gun beside her, blood still dripping. Yes. Yes, it was. She studies the weapon with morbid bewilderment and shudders, dropping it to the floor.
"This better not be the Purelands."
A movement catches her eyes and she gasped in surprise because of a tiny bundle that squirms and cries. Worry fills her as she realizes that the crying was not a hallucination and that, in fact, the baby she was holding when she died had fallen.
She focuses her chakra on her hand, performing a basic diagnostic Jutsu and sighing in relief when she finds no internal bleeding or fracture – she certainly couldn't do anything if that were the case. There were signs of a concussion and some bruises on the baby's arms and back, but it could have been worse. Much worse. Wrapping the baby in one arm, the baby quietens as she whispers soft words and injects a pain-numbing chakra, being the only thing she could do for the infant. She moves, noticing that further away there are silhouettes. As she approaches, the shapes of the other two children clinging to her reveal themselves.
The youngest boy, about five or six years old, was unconscious and Kana repeats the diagnostic process which showed no damage. Then she turns to the oldest, who is in his ten-year range, and immediately notices the red eyes in a complex weathervane pattern. The boy was clearly in shock, sitting up, hands in his hair and lips parted. Motionless and trembling, not noticing anything around.
"Boy?"
She calls out, as gently as she can, but the child seems lost in his thoughts. Even when she cautiously approaches him and makes a move to touch him, he doesn't react. The Kunoichi carefully diagnoses the child, feeling his chakra reserves drain at an alarming rate.
"Uh. Shit." Kana thinks when she realizes that he needs to force him to deactivate the Sharingan and needs to do it quickly because his chakra was dangerously low and it was practically a miracle he was still conscious. Activating her Sharingan, Kana traps him in a genjutsu that made him fall asleep, stopping the flow of the younger Mangekyou Sharingan and he falls to the ground without delicacy.
Kana grimaces as the child on her lap stirs and stares.
"What? It was a harmless fall." Kana says defensively, absolutely not thinking about how the baby had those judgmental eyes. The two looked at each other in silence until the creature in her arms cooed incoherently in the way that only babies do and then promptly pulled her hair out and put it in her mouth.
"No." She says pointedly, trying to dissuade the stubborn baby from drooling on her black hair.
The baby won.
"You smug little thing." Kana snorted at the little one.
A childish scream from Brat 2, the one who until then was blissfully unconscious, snaps her out of her argument (?) with the said smug little thing just to remind her that she was in a stressful situation. She tries to calm the child, who appears to be reliving the massacre, with no indication that he knew where he was, his brown eyes filling with tears as he cried out for his parents.
When Kana finally gets the boy to realize where he is, she regrets it because now the boy screams in fear of her, pointing in terror and repeating "ghost-nee-chan, don't kill me!" and the baby starts crying too so there are now two voices to make her ears metaphorically bleed.
The teenager clicks her tongue and her eyes turn scarlet, partly out of annoyance and partly because she has no idea what to do with a bunch of kids crying after the traumatizing shit she still can't quite process.
She feels guilty because the brat visibly pisses himself at the sight of his Sharingan.
"Fuck you, Itachi."
Kana casts a genjutsu to get both children to sleep and then there is silence. In the sudden stillness, the teenager sighs and then sits on the floor, overwhelmed.
She should be dead. She felt, in her core, without a shadow of a doubt, that she had died even though she hadn't stayed dead. Instead, she was apparently in a desert, out of supplies, in her pajamas, with two traumatized children and a snotty baby to tend to.
She doesn't even like children.
She gives herself a few minutes to just wallow and be a mess of emotions—confusion, bewilderment, anger, sadness, worry—before she starts charting the next step: survival. Hers and that of brats 1, 2, and 3.
"Time to find some civilization and discover where in the Elemental Nations we are."
Probing her bodily conditions – she felt strangely refreshed and her chakra reserves were full as if she hadn't used every ounce of it to fight Itachi – Kana decided she could risk a shadow clone for a few hours without completely wearing out.
The Uchiha acquires a determined look, arranges the baby in her arms, makes the necessary hand seals, and creates a shadow clone. A clone of her appears before her and carries the two unconscious boys.
She is almost ready to explore the territory. Only one more thing. Hesitating only a fraction of a second, the girl takes a deep breath and directs herself to the bloodied object she threw on the floor. The only weapon she had access to now was the one that had taken her life.
She takes the katana and cleans it in her plain gray pajamas and wields it until her knuckles are even whiter from the force and start running across the wasteland before her eyes.
When night comes it is very clear that these stars and constellations were something she had never seen in her fifteen years of life. As a kunoichi, Kana had done many missions around the world, and not recognizing the lights in the sky was something that should have been impossible... unless she wasn't in the same dimension. Panic rippled through her heart, though it is harshly pushed into the recesses of her highly active brain with the implications of the discovery.
They were nowhere near the Elemental Nations.
Hell, they probably weren't in the same galaxy!
Kana gazes longingly at the sky before casting a mind curse on her least favorite cousin of all.
"Fuck, Itachi. I hope you die choking on your dangos."
The kunoichi finds a cave in one of the desert mountains and settles in, dispelling the clone and releasing the others' genjutsu.
The children wake up. She sees the disorientation and panic on the two boys' faces as the baby in her arms shifts uneasily and decides on a direct approach so the children understand the seriousness of the situation.
"I'm Kana Uchiha, the neighbor of the house across from yours. Last night we were attacked by Itachi Uchiha. I tried to preserve your lives and I died for a while... But I'm alive now. Uh. Anyway, two of you are in good physical condition, but you, Katsuo will need to spend a few more hours to be able to use your chakra, due to the Sharingan.
There is acute silence for a few seconds.
"W-where... where... is Dad? Mommy?" Riki, the youngest with brown hair and black eyes, asks. Katsuo has haunted eyes and is clearly confused.
Kana clenches her fists and swallows her discomfort, anger, and sadness as she remembers the bodies scattered across the clan.
"What do you remember?"
"I-I…I…I don't know. We were sleeping and then... then...
"Help." The ten-year-old boy, with blue-black hair and dark brown eyes whispers. Then he goes on, voice scared, fragile. "Auntie told us to wake up, run and get help. Then... No. No. It wasn't real, it wasn't real, no."
He puts his hands on his head and sinks his fingers into his scalp.
"It was real. They are dead." She spoke.
Chaos ensues.
Kana Uchiha remains impassive in the face of the screaming and crying. When the two seem to have calmed down and comforted each other, Katsuo asks.
"Where are we? This... doesn't look like anywhere near the clan."
"Oh. Apparently, a different dimension."
"What?" He yells and narrows his eyes in suspicion. "Is this some joke? Look, if you're going to be talking shit..."
"I went through the same thing as you and died, boy." They shivered and Kana took note of Katsuo's contemplative expression. It looked like the boy was remembering something. "I walked for hours without supplies, weapons, or water, carrying you in my pajamas. I'm not in the mood for jokes, Katsuo."
"I... I don't understand... Katsuo-niisan... Kana-san? Are We far from the clan?" Riki frowns, confused.
"Hm." Kana nods.
"So... how are we going to get back?" Riki asked.
"I need to know how we got here first."
The teenager pauses, focusing her gaze on Katsuo, a possibility in mind. In fact, until now she'd suspected that would be the only reasonable explanation for their being there.
"Katsuo, when you activated your Sharingan did something different happen?"
The boy frowns, thinking, and then hesitantly nodded.
"A…thing appeared in the air, it looked a bit like a giant water bubble…and then, I think, we…Uhm…get sucked? Like water running down a drain. It was pretty confusing because you were still kind of on fire – I mean, you looked like you were on fire, but none of us were burning, and we were holding you when it happened…"
She blinked slowly, surprised.
"So it wasn't a hallucination, I was on fire. Hm. Something to ponder later. Now, however..."
"If I'm correct, your newly awakened Mangekyou is a spatial-dimensional type. There are some of these recorded in the ancestral clan journals."
"Then I can take us back!" The boy exclaimed, a hint of relief in his brown orbs. Kana shifts uncomfortably.
"If you were familiar with your Mangekyou and had enough chakra to activate it without dying, then yes, you could."
"Well then, train me soon! Maybe at night... we can go back..."
"No." She interrupts him pointedly. "You can't use your chakra now. And my Sharingan is different from yours, I wouldn't know what to instruct you in an afternoon."
"I've seen your Sharingan, it's no different. You have Mangekyou too."
Kana shudders. There was a reason why she hadn't told anyone about her Mangekyou. She didn't understand It very well, and really, it was exhausting as hell.
"Not one that can manipulate space or dimension."
"But we could..."
Kana sighed. That was why she didn't like children. They could understand but they didn't want to understand. Uh.
"I know you guys want to go home, but this is going to take a while. Training now would only lead to chakra exhaustion that could permanently damage your system, and then we'd be stuck here for the rest of our lives. Katsuo, you are our only chance to return home and I don't want to risk you activating your Sharingan and then you go and die of exhaustion in the process. Or, you know, you end up being alone somewhere else because you recklessly used the Mangekyou."
The boy grimaced in disgust.
"How long is 'a while'?"
"..ars..."
"I didn't listen." Riki said. Kana clears her throat.
"Some years." She started, seeing the pale faces of the smaller ones, and continued:
"You need to have a bigger chakra reserve and more control over it to use Mangekyou comfortably which would happen, under normal circumstances, in at least three years. Even if you are stubborn and put in as many hours as possible for it, it would take a year and a half. Not to mention the issue of adequate nutrition, which, frankly, we are lacking at the moment."
"S-so... are we stuck in another world for at least three years?"
"Yes."
Another round of pandemonium ensued. Kana rubs her temples. It's only the first day and she knows there are a lot of extenuating circumstances, but – seriously – why, oh, why does she have to deal with so much yelling?
She wondered if it would be too cruel to ask for compensation for taking care of the children when…if…she returned to Konoha.
Oh well.
At least she didn't use the Sharingan to avoid the children's general panic this time.
