Summary: As said in the description, this will be a Grim X Nel story, with some background Grim x Yoru action. It occurred to me when I thought, "Hey, they're both cats so, why not?" and then, I figured out that possible and promising chemistry between the two bipolar opposites of Grimmjow and Neliel. I was a fan of neither two pairings, but as you might have already suspected, I'm fond of GrimmNel. I've read quite a few fics to be convinced about the awesomeness of this pairing. ^_^ *crosses fingers and hopes for healing vomit on our kitty XD*

The Events: One and a half year after Aizen has been sealed and sentenced to 20,000 years to imprisonment in hell, Ichigo decides that it's time to stamp his foot down and recover his powers. Aizen is bound to return someday. Temporarily suspended of his former glory, Ichigo has to once more master and subdue his untamed hollow and there are no better teacher candidates for this task, other than Grimmjow Jaegerjaquez and Neliel Tu Odelschvank, the last of the Espada survivors. Grimmjow and Neliel develop a liking to each other, Yoruichi pokes her nose between them, blah, blah, you get the idea.

Here goes!

Chapter 1

It was evening, around 8 p.m. The sky was hued in a dark-crimson river, dressed in subtle white clouds and a smooth chilling breeze rustling the senbonzakura (spring) leaves scattered under the trees. It was the long anticipated after-war peace, repose at last. Everyone felt like the flow of time and events had slowed down after Soul Society declared victory against Aizen and his army of arrancar soldiers. All around Karakura resembled an ordinary average city in western Tokyo, since Ichigo's duties as the heroic substitute shinigami protector had been carried out successfully during the day. No more agonized insomnias because of Aizen's fixated gaze and definitely no more angst because of Soul Society's crazy requests. Most of all, no more of this mental burden for carrying out everyone's insane expectations (almost).

The neighborhood was rather quiet at this hour of the night, almost sadly quiet. It was obviously the right time to relax and relish some fine cooked dinner. The only flaws in this magnificent peaceful scenery were a periodic harsh and savage yelling, as well as an exasperated shouting that would come as a response to the first. It was none other than the Urahara candy shop, the humble home of a man that had brilliantly outdone Aizen Sosuke, the self-proclaimed god who dared manipulate his own creation against him, the hougyoku.

. . . . .

Tap-tap, tap-tap

The lone rhythm of dainty sandals inside the dark hallway. Unique hazel eyes serving as the only light to help and find her way, since it was Sunday and almost everyone had taken a day off from the shop to attend their personal matters. Walking proudly, almost in an elegant fashion, despite having trained for several hopeless hours with the orange haired boy and of course, without assessing the slightest sign of remarkable progress regarding hollowfication abilities. One whole week had already been covered, or rather wasted, since they had been invited to their new home and Ichigo still hadn't even learnt how to gain control over his leaking reiatsu. Bitter disappointment overwhelmed her stomach, causing her entire outfit to briefly clench in distress before breathing lightly again. A faint smile crossed her natural pink lips though, because it was just shifting time and she could take a break from this martyrdom at last.

Two slender arms raised and folded over her shoulders, gently lifting the locks of enchanting aqua sea-green hair, and then letting it cascade wildly down her graceful back, tossing the disgusting hot sweat away from her silky-soft skin. She desperately wanted to get rid of the white elastic fabric that almost felt like squeezing and suffocating her, because right now her uniform would just function as an unwanted heater. Her ample round breasts screamed for release from their bonds, starving for some cold, refreshing water.

Tired..

The turquoise haired girl silently sighed out of exhaustion, having nobody to share her discontent but herself. For her bad luck, Neliel had kindly offered to help Ichigo. If she only knew what she was getting herself into.. She didn't do it to help him get stronger, but purely because she cared too much about him and didn't want something unnecessary to happen regarding his inner other half. She had never expected though, the boy that had defeated the omnipotent Aizen, to be so inexperienced in general.

The soft and soothing echo of her clad feet suddenly halted after listening to the last harsh bawl. Hazel eyes shifting anxiously over her shoulder, expressing a distinct discomfort while staring at the darkness behind her. The former tercera espada remained silent for a brief span, taking a deep breath, before exhaling patiently. Once more raising her eyelids, then taking a tired glance outside the window. The tender fingers had dropped defeated from the fatigue, but they immediately clenched into vengeful fists, shaping the dark image of his impossibly sharp grin. Insecure thoughts flew out of the window's limits, dwelling around the unpredictable phenomena that surrounded electric blue.

I swear..If he's abusing my Ichigo again..

Swiftly turning her large chest the other way around, wet green locks swayed in the air and silence yielded at her commanding aura. Uncertainty had devoured her other emotions, unable to hide the fidgets on her lips.

Tap-tap, tap-tap, tap-tap

Neliel had restarted her pace, this time at a more brisk and petulant rhythm. She seemed quite determined, yet worried, causing the sinking in her stomach to get even worse and her protective instincts to awaken again. Only god knew what brutal methods he would use on the poor kid this time. Neliel stood firmly before the door she had gladly exited just a moment ago. The shop's secret training grounds. A pissed groan, gradually amplifying into a savage snarl skipped through the solid steel door and rang flatly into her sensitive eardrums. Hazel eyes narrowed vengefully towards that direction, as the blood in her veins started pumping faster, filled with adrenaline, purely reacting to his bestial vocal chords.

. . . . .

"I still can't see any-thing, Kurosaki. Try again.." The intimidating tone ceased for a second, sounding more of sarcastic now. "Harder!" He ordered, yelling again all of a sudden and triggering a shocked hollow shriek from the boy as a result.

Just hearing his ruthless voice felt like her stomach would leap into her mouth from the tense atmosphere that lied beyond the door. Nel's eyes lowered on the door's slide with extreme caution. For once, she had to catch him in action while performing his 'crimes'. Hands shivered damp, hesitating momentarily, a bit unprepared of what her eyes were about to witness. Twiddling slender fingers around the luring slide for a moment, considering whether she should go on, or just ask for strict explanations later. After listening to another desperate scream though, Nel squeaked in shock. Her whole entirety had bristled in alert. The girl bit her bottom lip, terrified of what her young, brave protector might be going through. Squeezing eyes to snap out of her hesitation, Neliel slid the door open with a confident push.

Closing the door with the same stealth, Neliel cautiously raised yet another vengeful glare. After carefully assessing the situation for a moment, reassurance found her eyes again, finally returning to her normal soft facade and pulse, sighing gladly at last. Fortunately, her beloved Ichigo was being cornered and mistreated as usual, but not labeled as 'abused'.

"I'm trying, I'm trying damn it! Shit!" The shinigami swore. The orange haired boy huffed nervously behind the black striped hollow mask, briefly rolling yellow hollow pupils to their edge and then over his shoulders, trying to make out what his cold blooded teacher was thinking of his progress.

"Fuckin' Lame!" Would be the answer.

Neliel glowered, pondering on the other man's gritting teeth, preparing to clear her throat loudly before his short temper would erupt into another outburst. She played a subtle smile on her lips however, making an estimation on how much more he could keep his raging fists shoved inside his hakama pockets. The threatening icy glance jumped viciously over Ichigo's slim bankai-shihakusho shoulder, piercing his wide shivering palm. The man's pissed eyes sought for any forming reiatsu there, but shit, he was worthless as trash. A growl, slowly getting fueled by Ichigo's incompetence started boiling inside his simmering chest, causing the first to flinch in fear and resume concentrating on his palm to keep up the effort. Neliel lightly shook her head, witnessing their silly persistence.

It's useless..

Eyelids dropped nonchalantly, convinced for zero improvement. If she only had the nerve the blue haired arrancar did, they could possibly get somewhere. The problem arose when her love for Ichigo wouldn't allow her to push him as far as her judgement willed. Nostalgic hazel eyes awakened again, this time on her insecure arms that were lapped under her admirable breasts. For some reason, after considering her sensitive womanhood Nel would always fancy a pair of electric blue eyes staring at her with a seductive glint. Curiosity to observe this wildness again lured her to look at the two stubborn males for a second time.

It was incredibly peculiar, how ice-blue, would be the first color to stand out among others, piquing her instant interest. She could swear that the most possible reason his hair were this teal, was because of the constant electrified atmosphere enshrouding him. He would always be so fired up and unresting, no matter what. The worst part, which she had just realized on this first week, was that he always needed to unleash that excitement on someone (or something). The urge to scowl and smile at him at the same time started fighting for dominance on her lips, reminiscing that this thrill, was sometimes released directly on her, one way or another. She wanted to clutch this unbelievable weakness of hers because she didn't remember protesting intensely whenever he would hit on her just to merely tease her for her cold greetings.

They didn't have a crush or anything like that, on the contrary, he was too loud for her likings and she was too passive for his appetite. For her, he was the case of a hot smartass and for him, she was a cold sexy bitch. The only reason they tolerated each other was just because that their conversations were rather 'successful'. That guy would spit some really amazing lines, a lot better than she could remember of Nnoitra's gross innuendos, or the disgusting smug chuckles that would come at completely random moments. On the other hand, he digged her big mouth because she could easily hurt his big ego with just a few crisp-cut words. They just rendered each other from boring, to interesting, attractive at the very most, but not charming in any case.

Meanwhile Neliel had made herself on a small bench nearby. One leg over the other in a tempting pose, the green haired girl bent forward and gently rested her chin on her hand, dropping her thoughtful glance and watching the motions of her sandal as it slowly expressed a subtle boredom, hovering upside down. Neliel reached for a pocket on her waistband's side, just next to gamuza's sheath. Skimming a few pages, her eyelids lowered appeased and she reclined on her back, relaxed. It was novel time.

"Nh..Nhhg...!" More consecutive and desperate hollow shrieks followed. The best the poor boy could do was to create some pink steam come out of his palm. Ichigo panted heavily from the huge effort he had been putting. Hissed in hopelessness, then touched his face and unsummoned the heavy life-draining mask. Ichigo impaled his sharp bankai blade on the ground, hands shaking, gasping for air and struggling to breathe properly now that the corrupting mask was gone.

"How am I supposed to read like this.." All of Neliel's mental images were suddenly banished from her mind in a quick flail of the hostile espada's arm. The sudden movement cast away Neliel's abstraction. Perking her eyes, Nel blinked in surprise.

"You hopeless shit!" An enraged fist punched Ichigo on the back of his head, causing his eyes to fly open and give another startled, this time human, shriek.

"This is the last fuckin time I show you how its done!" He briefly spat at him, then squinted his pissed eyes to gain some short self-control to demonstrate.

Ichigo groaned nervously, watching the espada's black boots padding next to him in an apparently calm and laid back manner. The teal haired arrancar halted with confidence as his sapphire eyes gazed forward. He took a quick peek at his rival's exhausted, yet resolved eyes, then snorted disgusted with Ichigo's 'handicap'.

"Che." He raised his chin high and clenched his teeth, taking incredulous, yet curious glances around the suspiciously hidden area.

"I don't care what crap she teaches you, but a cero..." Gazing lethally he appointed towards the tired, yet attentive strawberry boy again, making sure that he was not wasting his spit for no reason.

"A cero.." He repeated and emphasized, "Ain't just about focus or shitty meditation!"

Ichigo just kept listening to him, still resting and panting on his unyielding black steel. The sexta moved closer to him, then raised five ferocious fingers to attract his corroded attention. Neliel closed the book, leaving one finger inside in order not to lose track of her progress, crossed her arms under her breasts again, puzzled and curious to observe what method he would use this time. Her gaze traced from the espada's icy resolve, down to his predatory flexed hand. The tendons above his fingers strained.

"Order it..Command it..Only then it will obey you..!" He briefly explained in a confident tone, causing Ichigo's eyes to widen a bit and observe with renewed interest. The boy let go of his impaled sword and moved closer to the quiet and focused arrancar.

"Command it?" Ichigo inquired with a quizzical dark brown eye, still watching his teacher's empty palm.

The aggressive man just retorted with the edge of his blue eye.

"You are the king of yourself. Every part of your body is at your friggin disposal!" The espada lowered his eyes, watching the small twirling red light that had started forming inside his palm.

"What you need to do.." He continued, as Ichigo kept watching closely at the espada's serious eyes.

"Is to convince everything and everyone around you.." Now spirit particles started gathering from every single spot around them, like responding to his call, helping the red light to get wider and brighter. Ichigo was impressed at the power residing within the technique of cero.

His teeth slowly bared a cunning grin and he swiftly stretched his arm, pointing far away from them.

"..That you are the king!" Growling loudly he unleashed a lethal red beam that destroyed anything it touched in its path.

A dim smile of approval found Neliel's interest as she kept licking his proud number '6' tattooed back with her eyes. She didn't know why, maybe it had to do with the time she had lived as a human in a possible medieval age, but she liked that demanding regal demeanour of his. He was definitely not noble or pure as a king should, but most likely evil and ungallant. She couldn't deny that he possessed the passionate determination and pride of a true king though.

The man lowered his steaming hand, satisfied by the destruction he had caused. "You try it!" He demanded and intimidated the orange strawberry to try again.

Ichigo had shaped a nervous twitching smile at his unexplainable excited smirk.

"Evil..." Nevertheless, he complied and decided to give it a last shot. Ichigo summoned the fearsome hollow mask again. Eyes shut tightly, silence and a sheer focus. "Command it..!" Ichigo ordered himself.

Their eyes opened widely, making out an actual pink pellet that was being forcibly squeezed out.

"HAH!" Ichigo boasted proudly, losing focus in the process however.

*BΟΟΜ* The cero ball gleamed and exploded right in front of their faces. Neliel smiled, trying to suppress her giggling and steadily unfolded her legs as she took away the book to stand up. She knew well what would follow after that. The smoke caused by the explosion had almost been blown away to clear the scene. A silent grunt came sounding out of the smoke.

"You worthless..Piece of shit!" He gradually raised his tone to a yell. Ichigo responded with a nervous chuckling as his mask began shattering, and he was abruptly grabbed by two strong strong arms at his bankai uniform's collar.

The green haired girl suddenly dropped her smile however, sensing his merciless intent to beat up the kid.

"Enough!" Her shout cut through their spat. They were both startled by her incredibly authoritative and taming voice, gasping in surprise, then turning their pale eyes to their right to meet with their superior.

"N-Nel!" Ichigo muttered surprised and full relief spread on his previously apprehensive expression.

"Psh.." Grimmjow narrowed his indifferent eyes towards the green haired supervisor, as their training came to an end because of her intervention.

The blue attacker turned towards the orange defender again however, seemingly ignoring the approaching green cavalry.

"She's not gonna save you the next time!" He scoffed him, bringing his devious grin closer to Ichigo's nervously gritting teeth. After sniffing his amusing edginess he let him drop down and stare him from a higher and superior position, like mocking him. He continued showing him his vicious fangs, till he realized something that cut his excited mood.

"Tch. You fuckin ruined my jacket again.." He hissed, pissed at his tattered outfit, then moved away from the tortured boy to let him drop dead and breathe like a dog. Training session was officially over..

His usual laid back attitude soon returned. Grumpy eyes, smooth steady pace like nothing had happened and hands in pockets, with the exception of holding his jacket against his ribs. He simply narrowed his eyes and hardly lingered his pace, realizing that she had deliberately altered her course to block his destination. He lowered his head and dropped his eyes, shaping a shifty smile to her obviousness, seeing her walking in front of him and halting like a noble knight. Neliel stood in front of him, a bit lower than his height, but definitely in front of him. He opened his sharp eyes, momentarily dropping his sneering to convey her his annoyance, then immediately showed her that witty devilish smile again, as he unnoticeably scanned the seething disturbance residing in the girl's eyes. Their completely opposite spiritual pressures wanted to literally outpower and devour each other. Thus the tension building up between them.

"Grimmjow" She inclined in a quiet and guarded tone, still keeping her composure and trying to decipher the taller man's unreadable eyes. The undeterred sinister smile was still there though, causing her to clench her teeth behind her superficially confident lips, after a while of mutual glances. No good.. So much time together and she still couldn't subdue his guts. Moreover, it was like she was the one feeling that his piercing pupils were the ones peering her thoughts. She felt like she was going to sweat in front of this silent offense. Her toned stomach stiffened and her mid-lidded sober eyes opened a bit in defense, desperately waiting for the 'ice' in his gaze to break. She couldn't help but look elsewhere to catch her breath and break the train of thoughts. She knew he'd be a tough one from the first glance, but this..

"Neliel.." He finally replied calmly, giving her a sensation of extreme self-confidence. Her eyes slowly met with his again, trying to reread 'ice' more effectively. She detached her lips to say something, but after confirming the unfading assurance glazing his sapphire eyes, she pulled back her words and reconsidered. He shrugged a grin and cocked his eyebrows, satisfied that she couldn't tell which place in hell his cunning mind dwelled at. Nel furrowed her own brows in a suspicious glimpse, then cautiously walked closer to him going for offense, pointing her chin high and staring the hunter right under his neck, still trying to threat and intimidate him for both hurting the pure strawberry and for thinking that he was smarter than her.

The Sexta Espada simply walked past her invisible threats, throwing a quick peek on the pair of dead-serious golden eyes that followed his every single movement with mistrust. He could tell she wanted to pinch and beat him to death, but where would the fun in that be? He finally gave in as he walked away from her. The sexta's uncomplimentary laugh caused Neliel's attention to incline over her shoulder in mental reflex.

"Where are you going..?" She asked softly, almost whispering, unconsciously revealing some light interest in her tone. She wouldn't let him get away with this.

He sauntered, then stopped again, listening to the broad curiosity that aroused his feline senses. Her weak patience would always make his day and renew his interest in conquering her after what she had done to him. But he was a playful little cat and he had decided to play her little game.

Slowly lifting his hand over his shoulder, he gave her 'the finger'.

That's it for now guys. No much action, but you sure got the idea how they would possibly pair up. Next chap Yoruichi shows up! Anyway, I'd like some reviews/feedback with your opinions, as well as any ideas that might help me with the story. I don't guarantee a fast update!
