Warning: Disturbing thoughts. Animal cruelty. Love is a hard emotion to express when you're a psychopath. Yandere tendencies. Dark humor (to me anyway).

It has been a week since she remembers her previous life. It didn't take even a second for her to gleefully accept that she has been reincarnated into Narutoverse.

Of course, she fully intends on becoming a shinobi as that was a career that would allow her to kill other people and not be judged for it - what better occupation could a serial killer ask for? Additionally, she was the twin brother of one Senju Tobirama, the coolest ever Hokage in her eyes.

She got along well with both of her siblings, always cuddling against Tobirama's side or cooing at Hashirama whenever the boy became mischevious enough to play with her cheeks. She seldom sees her father during daylight, but her mother was around twenty-four seven to take care of their baby needs.

However, she knows that her cheery persona would not last for long. She could already feel that the euphoria she has gained from killing her former Captain and Lieutenant were diminishing at a steady rate. She guestimates that by the end of this month, she would no doubt have returned to the default settings of a killer doll.

The constant apathy (boredom) wasn't something she was looking forward to.

It didn't take a genius to see that all her cheer was gradually fading away. Her mother was the first to notice that she smiles less as time progress. She was beginning to become that child again, the one from her previous life.

A child that was different from the rest of the populace. A child that found everything to be boring. A child that was too smart for her age. A child that could not understand that clouting someone was not ok. A child that lacked social skills. A child that imitates the expressions and social niceties of others but does not understand it.

When another week has passed, she began to see her mother - who ironically enough was named Senju Nadeshiko - more and more like a stranger than a family member. She remembers her previous set of parents well enough to compare the two.

They didn't look at her like how Senju Nadeshiko looks at her. Senju Nadeshiko looks at her like how her former teachers look at her. She doesn't understand the look very well, but she knows it wasn't endearment. She loves her previous mother more. And her previous mother loved her too.

Senju Butsuma, one the other hand, loves her real self - not the cheery baby, but the apathetic one. He would often time put her on his lap as he whets his weapons at the end of the day. Or he would murmur under his breath about all the creative ways a shinobi could kill someone with a milk bottle whilst he walks around the garden carrying her.

Senju Butsuma looks at her like how her previous father looked at her. So she loves Butsuma like she loves her previous family. One day, she hopes that Butsuma would allow her to kill him to show how much she loves him.

Hashirama acts no different despite her lack of smiles. He continues to play with her cheeks, not deterred by her silence or the way she would stare hungrily at him. When she wasn't with Butsuma, she was with Hashirama, the talkative boy always gossiping about one thing or another.

His chattering occasionally causes her to fantasize about stitching his lips together or removing his voice box with him still aware, but he was also entertaining so she wouldn't act upon such daydreams. He reminds her much of her previous big sister, always mischevious yet has the most kills in their dysfunctional family.

Her twin brother, Tobirama, hasn't really formed a personality for her to compare him to anyone in her previous life just yet.

He was still just a baby. Someone who cries when they're hungry, cries when they need changing, or cry just because they felt like it. Nevertheless, she loves him above all others. One of the reason was that Tobirama was a beautiful baby, one she could never take her eyes off of. His albinism only compliments his features, making him appear ethereal.

But all in all, she knows that she loves herself the most, so it doesn't take a genius to figure out that her narcissism extends to Tobirama, who was her identical twin. That was the main reason why she loves Tobirama despite his lack of individuality. Not because Senju Tobirama was her favorite future Hokage, but because he looks just. like. her.

She shakes her head to rid herself of her musings.

Currently, she was in the living room with her brothers, Nadeshiko was at the kitchen preparing lunch, and Butsuma was training at their backyard.

She grunts when she finally accomplished sitting up on her own, her body swaying slightly as she struggles to find her balance. Whilst Tobirama blinks and continues to try to copy her movements, Hashirama squeals in delight at her infantile body's progress, clapping his hands and telling her how proud he was of her.

She only stares at him with her head tilted to one side, already returned to her 'default settings' as yesterday was the last day of the month. She feels empty.

There was no sense of accomplishment. No happiness at the praise Hashirama had given her. No disappointment that she couldn't feel anymore. No care that she has discarded her former self entirely and began calling himself Senju Takarama in his mind.

And Takarama was only bored. Bored of the way Hashirama would smile at him dorkily. Bored whenever Nadeshiko would try to get him to call her mother. Bored of hugging his twin. Bored that he was even bored.

'Ah', he duly notes, 'I really want to kill someone to get rid of this boredom'.

Takarama and Tobirama were now a year old. One has a head of spiky black hair and a pair of emerald green eyes, and the other has a head of spiky white hair and a pair of ruby red eyes. Their coloring was different, like night and day, but their features were mirror images of the other.

His twin was a bright baby boy, already able to form short, coherent sentences. He was even able to run after a gleeful Hashirama, his movements more fluid than the average one-year-old. If the albino had been born on Earth, he would be praised to the high heavens as a child genius.

Takarama, on the other hand, didn't bother to speak.

He knows he could, but he didn't care to. Though, at least, he makes an effort to physically keep up with Tobirama's accelerated growth. Narutoverse defies the Earth's common sense, where ninja children were advanced both physically and mentally.

Takarama was currently on Butsuma's lap, the man murmuring chakra theories under his breath whilst he idly observes his eldest son teach Tobirama some warm-up stretches to improve flexibility.

Takarama squeezes his pudgy fists as he blankly stares up at the birds perched innocently on the tree branches, warbling their song without a care in the world. He imagines squeezing their fragile necks, choking them and listening to them shriek in instinctual fear, the flapping of their wings erratic in their need to escape.

They continue their song.

Takarama continues making hand seals to improve his finger's dexterity.

They were two years old when Butsuma assigns an older, retired shinobi to train them on his behalf. The man was too busy caring for Nadeshiko, who was pregnant with their fourth son, to divide any more of his attention amongst three sons. Hashirama's training was far too advanced for the twins to join him at this point in time.

Unlike Tobirama, Takarama was not a natural sensor, as he has come to learn. He was actually the opposite of a sensor, much to his twin's amusement.

Whereas Tobirama was able to walk around with his eyes closed and not bump into anything, Takarama has trouble sensing any chakra outside his body. His twin explains that his eyes weren't at all reliable, to begin with, as they were sensitive to the light. Hence, to make up for his poor vision, he prefers 'seeing' with his chakra.

Although, unlike Takarama, Tobirama struggles to perform chakra manipulation exercises at first. Takarama has the unfair advantage of maturity at his side, however, and chakra manipulate came easy to him when chakra didn't exist in his previous life

By the end of their first lesson, Takarama manages to take five steps up a tree before he feels exhaustion creep behind him. Tobirama was able to walk two steps before he falters. Butsuma was pleased that he has another set of child soldiers that were like Hashirama - prodigious shinobi in the making.

Takrama didn't care. He only wants to be able to climb a tree quick enough to snag a bird. It was too bad there were no animals or livestock within the compound walls, only avians.

Senju Kawarama was born when the twins and Hashirama were three and six respectively. Tobirama was instantly enamored by the baby, cuddling it in his arms and refusing Hashirama's request to hold it.

Takarama calls it an ugly piglet, what with its pruney skin, scrunched up features, and pinkish complexion. Tobirama didn't seem to hear his barbed insult, his ruby red eyes focused solely on that thing.

It makes something inside of Takarama tighten uncomfortably, a hazy red appearing in his vision. There was also the intense desire to drown his youngest brother at the koi pond, which wasn't exactly something new, as he fantasizes about that often enough.

He tentatively places a pudgy hand on his chest, right above his heart, not at all understanding the sensation. He dislikes it.

It was then Hashirama chides him for making fun of their baby brother, which pulled him out of his brooding. And before he could snark at his big brother, Hashirama tells Takarama that he looks exactly like Kawarama when he has just been born.

Thanks to the recent weekly killings of avians, Takarama was able to feel more than a wooden puppet, hence he was disgruntled by that unnecessary comment and viciously jabs his pointy elbow into his big brother's ribs. Hashirama coughs out an 'oomph', holding his side as if in pain, but he was grinning too broadly to act otherwise, clearly pleased to see that Takarama was reacting and emoting more and more as of late.

Huffing at Hashirama's dreadful and unpleasant teasing (Takarama and Tobirama were beautiful babies, thank you very much), he glares at the hideous bundle carried by Tobirama and slides behind his twin to all but wrap his skinny arms around his twin's waist.

'You can't have him. Tobirama is mine. Mine to protect. Mine to own. Mine to kill. Mine mine mine.'

Takarama contemplates sneaking out of the compound as he continues to squeeze his pet raven's fragile neck. Its beak has been wrapped by a string to impede it from making any noisy screeches, and its wing feathers clipped in prevention for any flights.

Seeing that it was asphyxiating, he relaxes his fingers but kept them in place.

The raven futilely beats its useless wings and blunted talons against his wrist. Takarama ignores it, not in the mood to wrestle. He turns his head to look out his bedroom window. It was a beautiful day, truly tempting him to take a step outside the compound walls and search for bigger prey to kill.

He was envious that Hashirama was already doing courier runs.

Since the twins were only four this year, it was still too early for them to be able to leave the compound. Normally, he would be glued to Tobirama's side on lackluster days like these, but his twin was currently with Butsuma, doing who knows what. He has a feeling that Butsuma has been giving Tobirama private classes, though.

This left him to find new ways to entertain himself, which was how his beloved raven came into his life. The avian has been his pet for a year now, an investment of sorts. No one knew of its existence, not even his twin, as he often keeps it inside a small, wooden trunk whenever he went out to train.

His emerald green eyes stray to the crow that was as long as his torso and thick as one of his thighs. Perhaps he should rectify that?

"You're nameless, though," He murmurs, head tilted to the side, "I can't introduce you to Tobira, anija, and piggy if you don't have a name."

Bored with its pathetic wrestling, he releases it and watches as the avian crawls towards its bed. He giggles at the hilarious sight. How adorable. If it wanted to go back to its birdhouse, it only needed to tell him. He would gladly carry it to the wooden trunk.

"What of the name Karasu?" He asks whilst poking the raven with a toe. It dodges his next poke, which he assumes was its way of telling him that it dislikes the name.

"Tsubasa?" Another dodge.

"Tobu?" Yet another dodge.

Takarama was getting annoyed, so he threw the defiant bird to the other side of the room, only placated when it shuddered as it hit the wall.

"Satsujinki, then? Sacchan for short." At its lack of movements, Takarama figures that it was happy with its name. Good. He was beginning to run out of ideas. "I'll introduce you to my other treasures once anija comes back home."

With a smile, he removes the string from its beak, cradles his beloved pet to his chest, and starts preening its dark feathers.

As a person who doesn't fully understand the emotions (he was still learning), he imitates to the best of his abilities. He knows that birds would preen others they like, so he preens Sacchan to show his affection for it. And as a plus, preening helps with keeping his treasure in mint condition.

It was like killing two birds with one stone.

Not literally, of course.

Takarama would only kill Sacchan if the bird ever tries to run from him.

After he was done preening its feathers, he places Sacchan on his futon and reaches for a kunai, which was slightly blunt but whatever (he made a mental note to whet his tools later). It was high time for Sacchan to earn its keep. Despite the affection he feels for his pet, it shouldn't freeload off of him any longer. Everyone needs to contribute to something.

After all, there was a limit to his kindness.

Takarama traverses the forest with the grace of a stalking panther, traveling via tree branches like any good forest-dwelling shinobi. His beloved pet was with him, perched on his right shoulder with a home-made black hood strapped to its head, blending nicely with its feathers.

After having removed the raven's eyes and trained his pet to 'see' with its chakra using Tobirama as a reference book, it became his personal radar.

His brothers were surprised at the initial introduction, but after explaining to them that Sacchan was a ninkarasu and his assistant to help him overcome his chakra sensing handicap, they accepted his pet without a fuss. Now, the raven was always seen together with him.

Currently, Takarama was doing his first ever mission as a shinobi. A supply run.

His errand (because let's face it, this was basically a glorified shopping chore) was still within the Senju territory; a civilian settlement under their clan's protection. Hence, Butsuma wasn't at all worried about sending his five-year-old son out on his lonesome due to their lack of manpower.

This provides an opportunity for him to finally fulfill his cravings for a murder whilst he accomplishes his mission. Takarama had been getting bored of killing birds. Sure, he was able to get his weekly dose of emotions thanks to them, but it was a minuscule amount when compared to butchering humans.

He misses the blood, the viscera, the brain matter, the screams, and the thrill of it all.

"Noob. C12. T4."

Sacchan suddenly reports in a robotic tenor. Those English words were codes that he has established and drilled into his feathery pet's brain. Noob was the code for 'genin level chakra signature', C12 was the code for 'check your twelve o'clock', and T4 was the code for 'a total of four people'.

Takarama immediately makes a split second decision to abandon his current route and turn left. After a few more minutes, he clears his throat, a signal for Sacchan to scan again to see if they were being followed.

"Nevermore."

It took a few extra moments for him to truly believe that he has not been followed despite Sacchan's account that there were no more signatures nearby. One could never be too careful, after all. A whole decade of cat and mouse with the donut munchers and feds have made him a really cautious mass murderer.

Releasing the tension on his shoulders, he smiles sharply.

It was good to know that his pet's training has not gone to waste. Having a live chakra radar was handy for someone who lacked even the basics of chakra sensing capabilities. Sacchan has definitely earned its keep.

A/N: Dayyyuuummm! I'm so glad to see such positive feedback from ya'll. Thank you!

Now... Why did I ever decide that childhood snapshots would be a fun piece to write (≖͞_≖̥)? Baby years. Dreadful. Thought I knew better than to put myself in this position. Geez, I never learn (－‸ლ)! Should've just time skipped into teenage years.

Anyway, I don't know what goes inside the head of a serial killer since I've never met one. So, yeah. A lot of imagination in play when building the OC's character (*´∀｀）

P.S. The initial pairing was supposed to be TobiTaka twincest. But my plot-bunnies told me that inserting a slice of meat between the twin sandwich would make it more tantalizing (¯﹃¯*). So the pairing has been changed to Tobi/Mada/Taka threesome. What'd ya guys think?
