DISCLAIMER: I do not own bleach! The only things I own are Yukina Nerru and Aritsu Nerru.

The next day Yukina woke up to the sound of her cell phone ringing she flipped it open and check the caller ID it said Kurosaki. Yukina shrugged and answered it expecting it to be Isshin "Hello?" she called into the phone.

"Aa, Yukina?" Ichigo's voice sounded.

"Ichigo? I didn't know you had my number." She said astonished.

"I didn't my dad gave it to me, he asked me to teach you some martial arts so you wouldn't be completely helpless…of course if you don't want to do it I understand." he sounded like he didn't completely want to teach her but she agreed anyway.

"I kind of told Tatsuki-san that I would hang-out with her for a little but then I can give you a call and you can teach me, do you have a cell phone number?" she asked grabbing a pen and a paper and copied down the number then she headed out to meet Tatsuki at the park.

"Yuki-san!" Tatsuki called to get Yukina's attention.

"Tatsuki! Do you want to spar?" she asked Tatsuki while they were stretching.

"Are you sure you can handle it? I'm really good." Tatsuki asked slyly.

"Somehow I think I can manage." Yukina answered cryptically the both got up and Tatsuki quickly aimed a kick at Yukina's head. Yukina brought her hands up and blocked it then pushed Tatsuki about three feet away, they charged at each other aiming punches at all their open spots. Yukina searched for Tatsuki's weak spot it was hard because Tatsuki was so efficient but she finally found it and aimed a hard kick sending Tatsuki straight to the ground.

"Ow, " Tatsuki winced while getting up.

Applause sounded from behind them Yukina turned around and saw Ichigo ", It doesn't look like you really need training after all." he commented with his eyebrow raised.

"Oh no that was just beginner's luck." Yukina laughed nervously.

'You got carried away dumbass' Kurai-tenshi snickered in her mind, stupid sarcastic teenage boy.

'Shut it' she threatened.

"Well come on I'm going to take you to a roof top, it's easier up there." he said grabbing her hand a leading towards the busy side of town.

"Bye Tatsuki-san better luck next time!" she called while she let Ichigo drag her towards a particularly tall building.

He jumped on top of a dumpster and held his hand out "do you need help getting up here?" he asked.

Yukina glared at his condescending attitude towards her ", No I can do it on my own."

"Fine, "Ichigo replied as if he didn't really think she could the next minute she was standing next to him ", h-how did you do that?" he staggered.

"I jumped, silly!" She laughed, the two began to climb up the fire escape to the roof, Yuki let Ichigo help her up onto the roof top after that.

"Alright ready?" he asked after he taught Yukina the basics, Yukina nodded and Ichigo came at her. Although she acted like she couldn't do it and Ichigo winded up landing a kick in her stomach.

"ack!" she spat while holding her stomach, he really kicks hard.

"Oh come on Yuki-chan, I know you can fight...stop hiding it I saw you and Tatsuki. those moves you pulled were no beginner moves, " Ichigo said crossing his arms over his chest.

Yukina rolled her eyes he was really getting annoying ", If I really fought you...I'd kill probably kill you" she giggled, although she wasn't completely lying.

Ichigo raised his eyebrow ", well then I guess I better get serious then?" he removed his shirt and Yukina blushed.

"Eh...was that necessary?" she asked looking away.

"Does it bother you?" he asked with a snicker.

Yukina's blush became more intense and she glared at Ichigo ", No!" she lied, Before they began the spar her eyes flickered quickly to Ichigo's chest and then back up to his eyes. It seemed he hadn't noticed and Yukina let out a sigh of relief 'that was a close one' she thought. 'Sukebei' Kurai-tenshi shot at her causing her to roll her eyes mentally. Ichigo blindly charged at her and Yukina did a cartwheel to get away in the midst of her cartwheel she kicked Ichigo in the face, he grunted and sprung at her again this time aiming for her legs, Yukina didn't have enough time to recover from the dizziness that was left from the cartwheel and she was taken off guard when Ichigo tackled her to the ground.

'Time to quit, you don't want to give anything away do you?" Kurai-Tenshi's voice sounded in her head.

'You're right,' She answered

"Okay, okay you win!" she grunted and pushed him off of her ", You're heavy Ichigo-kun"

"Gee thanks" he said sarcastically while glancing at his watch, his eyes widened ", Oh god is that the time? I gotta split do you need help getting off the roof?" He asked.

"I think I'll manage if I fall and die on the ground I'll call you" she joked Ichigo rolled his eyes at her and jumped right off the side of the building 'tch, he's so reckless and lucky that I'm not a regular human." She commented before following Ichigo off the side of the building and then heading towards his apartment.

Yukina knocked on the door of the apartment screaming "Isshin! Isshin Kurosaki!" The front door was thrown open but that didn't stop Yukina from knocking on whatever her hand came in contact with next.

"Ow, Ow, Ow, Ow, OW! WHAT IS IT YUKINA-SAN!" Isshin's voice screamed.

Yukina stopped knocking on the door and blinked twice wondering when the door was open then she snapped out of it and glared at Isshin "What the hell was that for! It's pretty damn hard to hide being a shinigami if you stick me with your son every five seconds of my life..." She bellowed hitting Isshin on the head once more before stepping inside the apartment. "Are you going to train with me or what?" she scowled.

Isshin lead her to a basement room that looked exactly like the training room under Urahara's Shoten only it was night time here "Kisuke built it for me, no healing." Isshin commented before shutting the door and sealing it with reiatsu which was a special ability he had.

"Is Ichigo that stupid to never notice this?" She asked looking around.

"I guess, I mean it's not like I actually try to hide it...one time Yuzu found it and I knocked her out and told her she was dreaming it." he laughed they both changed into shinigami and picked up their bodies and put them off to a side.

"Ready to get beat, old man?" Yukina taunted while unsheathing the pure white Kurai-tenshi.

"Oh yay finally a shinigami fight I've been waiting to test our strength for a while!"Kurai-tenshi cheered in Yukina's head.

Yukina smirked ", yeah, yeah just don't disappoint me." She said aloud with a smirk waiting for Isshin to get in his stance.

"3...2...1...Fight/Go!" the two of them called in unison before flash stepping closer. Yukina raised Kurai-tenshi above her head and brought it down to block Isshin's thrust, a loud clink of metal sounded and Yukina jumped back before quickly charging again. This time she brought Kurai-tenshi for a low swipe but was blocked by Isshin, she jumped back again to regain herself but Isshin was too quick and flash stepped in front of her. Yukina gasped and rolled out of the way just in time to get nicked a little by the tip of his zanpakuto she groaned and held her side to stop the bleeding. Quickly she stood up and held her blade horizontally and put her left hand on the blade, she jumped back onto a cliff to further the space and pulsed her reiatsu screaming ", Kurai-tenshi Sakebi!" Isshin smirked and disappeared but didn't expect Kurai-tenshi's sound wave to be so large and was hit anyway. He grunted as he was thrust backwards his shinigami robe town across the chest and he was now bleeding. Yukina jabbed Kurai-tenshi into the ground and jumped off the cliff bringing him with her with a slight tug, she landed on the ground surely on her feet before slowly advancing on Isshin.

"Bankai!" he yelled, suddenly he was engulfed in black flames and when the dissipated he was in an outfit similar to Ichigo's Bankai outfit only his Zanpakto was now longer, sharper, black, and double bladed.

Yukina snickered and brought her right hand over the left side of her face and pulled down her Vizard mask, Isshin's face brightened and they both flash stepped closer to each other ", Akuma no Houyou!" Yukina bellowed before quickly stepping back to let her zanpakuto transform. She swung the blade around two trees and back into her hand confusing Isshin but with a slight yank the trees turned to dust and the chains were closing in on him.

"Getsuga Tensho!" he called at the seemingly last minute breaking the chains.

"Return." Yukina snarled as her zanpakto began to reassemble.

"That was a neat trick, " Isshin appeared right in front of Yukina and brought his zanpakto down on her shoulder, she cried out and then pushed back causing Isshin to go soaring, She flash stepped to the clearing and gripped Kurai-tenshi tightly ", Sakebi!" Yukina sliced the blade down vertically and dark purple flames flung towards Isshin with a hellish screech.
Yukina smirked as Isshin tried to shunpo away but the attack was too fast this time she had put enough force into the swing that gained momentum quickly the flames hit him but to her horror it went right through and Isshin's body faded.

"Nani?" Yukina screamed in bafflement. Suddenly the feeling of cold metal was against Yukina's neck and she groaned.

"I win," Isshin grinned, Yukina glared at him but waved her hand "Fujiken"

The two filed out of the room and Isshin clapped Yukina on the back and ruffled her hair "Alright kid I'll see you tomorrow okay?" Yukina swatted at his hand but nodded and waved good bye before heading home.
