LEGAGY

When Urahara was tasked to train the twins, he was quite excited. He decided that since this time around there was no sense of urgency or emergency involved, he would start slow and with the basics. The eldest twin had always been in possession of excellent reiatsu control. The youngest was slowly coming into her own powers since she was the slowest to attain a finer control necessary to call upon her powers. He was told that the youngest twin could only sense the spirits but if she came in contact with one with a strong enough reiryoku or a compatibility with her wavelength she could see quite well enough.

Kidou training would be perfect. It would accomplish the task of honing and directing the twins' wavelength so that they could put their impressive reiatsu to good use. He would build their strengths up steadily and help them gain full mastery of their gifts. No more rushing like their older brother. He wanted to see what a Kurosaki could accomplish when there wasn't a proverbial gun held against their unusual heads.

He was very excited to meet with such raw talents, unsullied and untested. He should've known better. He should've started with baby steps-on this case-a piece of paper and colored pens. Or maybe even puppets. He never should've expected to watch them fail and then teach them what was needed afterwards. Kurosaki's do not fail. They conquer. They overcome. They find expectations to obliterate.

Kurosaki Karin was a lethal force confined in a small, complex package. Ichigo was like a force of nature. You had nothing else going for you but to accept it and get the hell out of the way. That was it. And in some weird way, Ichigo's monstrous strength was easier to see, appreciate and dodge from.

His sisters were on some scale-a whole lot scarier.

Kurosaki Yuzu couldn't see ghosts clearly enough to be bothered by them. But she did emit the same, though subdued aura that leaked out of her brother like the stinking Nile. When given proper instructions for the first time, she finally harnessed the inert reiatsu inside her. She, like her twin, took to Kidou like duck to water much to the chagrin of her brother who couldn't control his own massive energy if it bombed him.

One lesson-a single instruction and a five-minute demonstration was all it took for the twins to grasp what students in the Academy needed for half a year. A few hours to memorize all the basic incantations for the lowest to the high 90's. A few hours of enduring snickers from Yuzu and mutters and curses from Karin over 'dumb, annoying, unrelatable words and idiots who think of rhymes that doesn't make sense' and she declared that she would rather actually see if she could do them rather than just read about the theory. All throughout her harangue, her twin smiled and giggled and agreed but nevertheless studied with good grace and patience. Her twin was all for it, provided Karin did it first. And so she did.

When he told her to concentrate on calling up her reiatsu and allowing it to flood her being until she could feel it down to her fingertips, he thought the words might be too vague. He forgot to read Youichi's memo that stated that the dark haired twin started fighting Hollows months before Ichigo lost his powers using nothing more than her reiatsu filled soccer ball.

And so when Karin stood up and then closed her eyes stilling all movements and minute twitches of her body he absently noted the fact and continued to simply watch. When she became still as a statue, he took a deep breath. When her reiatsu flared out of her in a visible wave and then coalesced around her like a bright outline he took a prudent step should've taken one look and started running. But he was a curious bastard and so he pressed on.

Karin then pointed at the target he placed on one of the craggy outcrop of rocks that littered the training ground. He knows she had the reiatsu to do the job, but he didn't really expect her to understand what he meant with such a simplistic explanation.

He had never been so glad to be proven wrong. The eldest twin didn't just become focused. Not just quiet and unmoving-but rather eerily, compellingly still. She stood, arms on her side, feet apart and braced. She looked at a point in the distance, took one deep breath and closed her eyes. It was all the warning she gave him. When she opened her eyes next and expelled her breath all hell broke loose.

Her eyes gave it away, those unusual purple-grey eyes that she shared with no one else in her family-those same orbs that suddenly shimmered and became illuminated in a startling shade of brilliant gold unlike her brother or her father before her. While she expelled her breath, she raised her right hand, extended two fingers and he couldn't help but think they looked especially delicate and dainty considering what a tomboy the eldest twin was.

Her thin lips parted and he waited for her husky voice to start the incantation. What he got was her voice simply saying the name of the spell in a tone of voice that was an eerie reminder of Kuchiki Byakuya's cool clipped tones.

Hadou No. 4: Byakurai

An arc of pure white energy shot of her fingertips and fired straight into the target. The shot obliterated the five foot rock into rubble. But she mustve slighty changed her stance at the very last second because her shot landed on the very edge of the target, making her lose her mark.

He expected her to curse and complain-as a soccer player he would've expected a better aim-but she didn't say a word. Even when her twin came up to her and laid a hand on her shoulder her eyes still looked on at the target. A heartbeat and then another, she gave out a shuddering breath and then finally tore her eyes away from the wreckage.

"Sorry..."

"Karin-chan? Are you ok? That was brilliant! That was amazing!"

"Hmm...we need to work on her aim."

"No you don't…"

Yuroichi sauntered into the training fields with a wicked smirk on her lips and a gleam in her eyes that made Urahara's hair stand of end.

"She missed the mark-"

"She didn't miss anything. She changed the trajectory. She didn't want to hit that."

"That?"

As if suddenly summoned small brown bird emerged from the smoke, clearly disgruntled but unharmed.

"She sensed it."

"What?"

"Right at the moment she was about to fire Byakurai. She had to change the angle of her shot at the split second a life force registered across her senses. Ichigo-boy's sister is even more attuned to life-forces and energies than anyone else in this place."

"I guess I should be thankful she is…"

"You should be thankful she's bare handed."

"What-? Oh…"

The realization that Karin could use her reiatsu effectively without a weapon was no surprise. The fact that she could manage a destructive force without a zanpakuto was. Realizing that she could pack a punch in a something as mundane as a soccer ball wasn't reassuring. It certainly didn't reassure Urahara when Yuroichi continued to smirk at him. The feeling didn't get any better when he saw the grin painted on the twin's idiotic father.

When Yuzu tried Kidou she did it with remarkable flair-brilliantly efficient if not with the same deadly force and accuracy as her sister. But it came with the added bonus of being naturally attuned towards defensive and healing kidou. Her barriers were like reinforced walls of steel-the kind of shield that would take a kidou spell beyond the high 90's to even scratch. Any weaker and the barrier would-if it could-spit your spell back at you.

When Karin and Yuzu were trained to achieve their zanpakutou it was expected they would wield a powerful weapon. Urahara should really have learned by now. When asked to meditate to attempt and call forth their zanpakutou, oddly enough it was Yuzu who immediately managed to manifest a pair of slim kodachi's. They fit the defensive personality of the youngest twin who did not seek to fight-only defend herself if called on.

Yuzu's zanpakutou looked like a stylized pink kogai kanzashi when in their sealed form. The slim piece was covered by of all things small strawberry design and an unusual cluster of small amber beads that looked like the sun on one end with a delicate spray of amber beads cascading from beneath the other. She took to the habit of wearing it on her hair and it certainly proved to be a distracting reminder to their older brother that they were essentially a family of living Death Gods. The irony wasn't lost to everyone but those that knew them. The twelfth division captain called them interesting speciments, Byakuya considered their very natures an affront to discipline and Zaraki issued challenges to be met the moment they plop down and die.

The eldest twin however put even her own family's impressive legacy of producing extremely strong swords to shame. With Engetsu and Zangetsu, they expected a similar weapon and Yuzu's twin blades seem to indicate at least some measure of propensity towards swords that reflect their owner's desires and level of strength. They expected everything from a katana the length of a meter stick to a meat cleaver that could decapitate a whale.

But even within their own family the Kurosaki's manage to defy their own odds. Karin's zanpakutou shouldn't even be called a weapon. It's an arsenal. Or to be more correct, her sealed shikai wasn't even a singular blade but a host of items that defies all but the most analytic of minds.

What she had managed to manifest wasn't a single weapon at all but a whole slew of them including her very own mascot. In their sealed forms, Karin's zanpakuto was a simply a single ear-craft earring from which dangled a silver fang, two slim bracelets and a small , a small snow white pup with gleaming gold eyes.

Unsealed, they manifested into a scythe that could then be reworked into two separate weapons—a chained sickle and a wakizashi. The pup actually grows into a full sized wolf. Urahara and Yuroichi speculates that when in Bankai, Kurosaki Karin would probably have a pack of wolves at her command-faster than the wind and shoots white laser like flames when they howl. Truly, a more lethal Kurosaki had never been born.

The Kurosaki's sibling are a walking strike team-the complete unit intended for offense, defense and medical treatment. Yuroichi have found the perfect 3-man cell for any job—including but not limited to world domination and end of the world scenarios.
