"That's because this method only tells you generally where the reiatsu is coming from. When beings with reiatsu fight they release their reiatsu all over the area. Using pure reikaku sensing alone isn't going to cut it. All you'll see is a mass of their reiatsu spread all over the place. It can help you pinpoint the general location of the person, but it won't help you see the person's exact location. For example, if you stayed here and I went outside my shop I can use my reikaku sensing to tell that you are in my shop, but I wouldn't be able to tell that you were sitting down or that you were by my table. So you see I can pinpoint your general location as in the shop, but other than that I can't actually see your physical form."

Kishin let out a sigh. "Haaah. What a bother. Then...what about Tosen? He's blind but doesn't he use reikaku to see?"

Urahara once again clapped his hands in approval. "Excellent Chigetsu-kun excellent! I'm glad you brought that up. Tosen is a special case. I already investigated his background. He was born blind and therefore his reikaku sensing that would normally amplify his vision instead was dispersed into his other 4 remaining senses."

Kishin's eyes widened in realization. "I see. So it's not that Tosen can see with reikaku per se, but rather he is using something like echolocation."

Urahara smirked and nodded his head. "That's right. For giving up his sight from birth he has enhanced the entirety of his hearing to a new level. When enhanced through reikaku he can hear the reiatsu pulse of other spiritual beings and see them in his mind. There are limitations to this though, for example. He is unable to see what your face looks like. He can't tell what color your skin is or what color your clothes are."

Kishin pinched the bridge of his nose feeling a bit of a headache from all the thinking. "But isn't this still a feasible method to fight Aizen? Just close your eyes and focus on using your reikaku to sense his presence."

Urahara shook his head. "No no. First, to do so it takes a great amount of focus and concentration to pinpoint someone's location exactly with reikaku. Remember, you can find their general location, but if you want to be exact and know where they are standing, that requires a great deal of mental energy. Normally one would have to remain completely still in order to succeed. And second, the method you described is probably only feasible for you since you have not seen Kyoka Suigetsu's release. Although you'll have to train for probably a hundred years at the very least if you want to be able to use this method in battle like Tosen. For us and many others it's too late."

Kishin just frowned. "Is it because you all have already seen Kyoka Suigetsu?"

Urahara became serious as he nodded. "Correct. Remember the power of Kyoka Suigetsu is complete hypnosis. Even if we tried to use this method now it won't matter. Aizen would have complete control over what I hear and make me see false images of him."

"Haaah. Well, that's a shame."

Urahara just rubbed the back of his neck replying with a self-mocking tone, "I know right? Ahahaha..."

"But...Urahara-san. It is to my understanding that Zanpakuto's release their own unique reiatsu. While it is greatly similar to that of their wielders, it is slightly different. Couldn't you practice using this method to better guard yourself against Kyoka Suigetsu?"

Once more Urahara sighed and shook his head. "Not unless we can actually get close enough to Aizen or his Zanpakuto. I find myself repeating this a lot but, remember what I said? One can use reikaku to generalize a person's location, but not their exact position. Worst is that once Kyoka Suigetsu is released it will disperse its reiatsu into the surrounding area. Even if we try to sense its location we wouldn't be able to pinpoint its exact position. The only surefire way is to actually be in contact with his Zanpakuto and confirm where the reiatsu is coming from, but do you really think Aizen would just stay still and let us hit him? Plus, there's one other problem. A flaw especially for those who have already seen Kyoka Suigetsu."

Kishin frowned as he thought about it as well. "Your other senses will interfere...right?"

Urahara nodded. "Correct. Even if we focus with all our might using the method we discussed, Aizen can still disrupt our other senses and leave us scrambled in the head. Think of it like listening to your music with headphones in the middle of a loud club centered inside a volcano. Even if you try to focus on the music in your headphones the club music would overpower it and distract you. And if that doesn't do it then the scorching heat from the volcano will break your concentration. That's just the tip of the iceberg of what Aizen can do to disrupt our senses. That's why you're so very important Chigetsu-kun. You haven't seen Kyoka Suigetsu."

"Tsk. Sorry to break it to you but I don't have any plans to fight Aizen."

Urahara just waved his hand in the air. "Now now, don't be like that. I have a feeling that whether or not you have plans to fight him, you'll probably be forced to face him at some point. You should prepare yourself as much as possible if and when that time comes."

"I know." Kishin replied in seriousness. He stood up and stretched his back before asking, "Can I borrow the underground training area?"

"Eh? Ummm...sure. What for?"

"What else? To train."

"Ahahaha, sure sure."

"Thanks. By the way, where's Yoruichi? I haven't seen her for awhile."

"Ah, she's actually in the underground training area right now."

"Oh? Then...that's actually perfect timing."

"Perfect for what?" Urahara asked, however he didn't receive an answer as Kishin removed a rug and opened a hatch on the ground jumping down to the training ground beneath the Urahara Shop.

Fwish!

Thump.

He landed on the rocky terrain and caught sight of Yoruichi taking a nap nearby.

So she came down here to sleep? Not a bad idea I suppose, though her choice of the rock hard ground isn't exactly what I'd go for.

He slowly made his way over to her and lightly tapped her foot with his own. Yoruichi stirred a bit in her sleep but otherwise didn't wake up. Kishin just grinned amusedly and tapped her foot again, this time harder. Once more she just stirred and groaned. "Ngh. No. Milk." She quietly let out.

"Yoruichi?" He tried calling her name but to no avail, so instead he bent down by her face with a mischievous glint in his eyes. He pinched her nose and covered her mouth as he began counting down in his head.

One...Two...Three...Fo-

"PAH!" She exhaled and inhaled a deep breath of air as she jolted up completely awake. "The hell is going on?!"

Kishin just grinned and greeted, "Yo. Yoruichi-san. And good morning."

She turned to her left seeing a smug look on Kishin's face and huffed. "You? Well this is unexpected. Can I give you a word of advice?"

"By all means, please do."

"Heh, cheeky brat. Don't wake women up like that. How're you gonna find yourself a wife in the future if this is how you wake up a sleeping beauty such as myself?"

Kishin just gave her an innocent and confused look. "Huh? You? A sleeping beauty?"

"What's that? Are you doubting my good looks?"

"Nope, I mistook you for a black cat that brings bad luck."

A thick vein popped on her head as she sat cross legged and said sternly, "Oi! Don't bad mouth my cat form. I take great pride in it you know!"

"Pfffft! Hahaha!"

"What's so funny?"

"Nothing. It's just that of all things for you to get angry about it turns out to be your cat form. So that's your weakness huh?"

"Tsk." She clicked her tongue before letting out a sigh. "Haaah. Alright, you woke me up for a reason right? What's up?"

Kishin also turned a bit serious at this moment as he asked, "I want you to teach me how to use Shunko."

Yoruichi involuntarily flinched at his request. She carefully studied him for a good long minute before she slightly furrowed her brow and carefully asked, "How do you know about a technique like that? Did Kisuke tell you?"

Kishin just smirked. "I'm exceptional."

"Hmpf. More like odd."

"Call me a box of tricks."

"Or lies."

"Come on. Don't be like that Yoruichi-san."

She stared at him a bit longer before sighing in defeat. "Shunko huh? Was it Yushiro who told you?"

Kishin just shrugged his shoulders. "Is it so bad that I know about it?"

She just leaned her cheek against her fist and waved her hand in the air nonchalantly. "It's not that it's bad per se, it's just that I'm quite shocked. There's really only two ways to come by this technique."

"Oh? And what's that?"

"The first way is to learn about it from the Head of the Shihoin Clan. This is a special technique that is documented and passed down only to the Heads of the Shihoin Family."

Kishin raised his eyebrow in curiosity and asked, "Then the second way?"

"That's to be smart enough to put the pieces together and learn it by taking the Onmitsukido training foundations to the pinnacle."

"Eh? The Onmitsukido?"

"That's right. The training regiment of the Onmitsukido is modeled after the necessary qualities one needs to eventually learn and activate Shunko. Although currently I don't see anyone in the Onmitsukido that actually has a talent for it. Actually...maybe Soi Fon...but I haven't seen her in action for a long time so I can't really say if she's reached that point of enlightenment yet."

Kishin just rubbed the bottom of his chin in wonderment. "Hmmm...I see. During all this time I haven't heard or seen Yushiro use this technique. Does this mean he's keeping it a secret for now?"

Yoruichi's eyelid slightly twitched. "Hoh? So it wasn't Yushiro who told you. You're a box of secrets aren't you?"

He just raised his hands up in an innocent gesture. "Come on Yoruichi-san. Are you really that surprised after everything that has happened? I knew about Aizen and the Hogyoku. Surely me knowing about Shunko isn't that shocking."

She let out a sigh and stood up stretching her back. "Ahh, well you have a point. Okay, so you want to learn Shunko huh?"

Kishin stood up and nodded. "That's right. Please teach me."

She carefully studied him for a bit before saying, "Do you know what Shunko even is?"

"If I'm not wrong it brings together the form of Hakuda and Kido right?"

Yoruichi just smirked. "In essence, yes, but it's not that simple. If your Hakuda skills aren't at the mastery level then the Kido released in this form will cause you to end up hurting yourself. Your speed also needs to be up to par to match your Hakuda skills so when releasing your Kido in the form of Shunko you don't end up killing yourself from the release of your own power."

"Okay. I think I'm good on all three fronts."

Yoruichi just grinned and shook her head. "Convince me."

"How?"

"Hehe, if you can tag me in 1 hour, then I'll consider teaching you the technique."

Kishin smirked and nodded. "Alright, I accept the challenge. Any special conditions you'd like to impose?"

She thought for a moment before nodding. "No Kido or Zanjutsu. And since it'll be a game of tag I'll be nice and won't fight back. Catch me if you can."

Kishin thought about her listed conditions for a quick second before agreeing. "Okay. Sounds good to me. Oh, but there's one more thing."

"What is it?"

Kishin gripped the front of his shirt and pulled it off to the side revealing the tattoo of a snowdrop flower on his left pectoral. Yoruichi immediately understood when she saw it. "Gentei Reien huh?"

Kishin nodded. "Yeah. I only have 20% of my power so I can't really give my all when chasing you."

Yoruichi just thought for a moment before she shouted, "KISUKE!"

The loud thumping sounds of someone scrambling about could be heard before they both saw Urahara poke his head out from below the ceiling of the training ground. "Y-Yes?" He replied.

"I need you to put a temporary Gentei Reien on me."

"Eh? Why?"

Yoruichi just smirked. "To make the challenge fair."

"Challenge? What challenge?"

"Oi, can you do it or not?"

Urahara just awkwardly rubbed the back of his neck. "Ahahaha...alright alright, one second." He fumbled around a bit and mumbled to himself before he arrived before Yoruichi with a cat sticker in his hand. Kishin raised his eyebrow both confused and intrigued and asked, "What's that?"

Urahara just grinned. "This is a pseudo Gentei Reien. It'll suppress 80% of Yoruichi's reiatsu. The difference is that she can pull off this sticker anytime she wants so it's only useful for doing stuff like this."

Urahara then stared at Yoruichi with a mischievous glint and semi-lewd look in his eyes as he said, "Y-Yoruichi-san, ahem. Please lift up your shirt for me so I can place this on."

She smirked and decided to tease Kishin who was watching everything and so she replied, "Please be gentle okay? I'm delicate."

Urahara nearly had a nosebleed. "Y-Yes! No problem. Now if you please."

Yoruichi glanced at Kishin's unperturbed expression and just let out a sigh. "Ah, forget it. The kid's not taking the bait."

Urahara was about to protest but Yoruichi just smacked him on the head.

Whack!

"Ow! Y-Yoruichi-san?" He said in confusion as he rubbed his head.

She just took the sticker off of his hands and stuck it on her shoulder. "We've got a minor here."

He just pouted a bit. "Then later?"

She just stuck her hand in his face and pushed him away ignoring him. "So Kishin, you ready?"

Kishin just smirked and replied, "I don't mind giving you 10 seconds for hat n clogs to relieve himself."

Yoruichi just laughed out loud. "Bahahaha! You hear that Kisuke? You've just been labeled a 10 second wonder."

Urahara just coughed to clear his throat before playfully responding, "Ahem. Be nice. At least give me 1 minute."

Bam!

"Ow!" He exclaimed as Yoruichi hit him again.

"Alright, enough play time." She then turned her attention back to Kishin and asked, "You ready?"

Kishin bent down and removed his ankle weights really quick before he nodded. "Whenever you are."

Yoruichi grinned at his actions before shouting, "Start!"

FWOOM!

The both of them instantly blurred into the wind as Kishin chased after Yoruichi's back. They whizzed through the training ground dashing and prancing, sprinting and racing only leaving behind a streak of orange and white in their wake from the color of their clothes. Yoruichi was inwardly shocked as she compared Kishin's current speed to the last time they played tag. She knew he handicapped himself last time due to the ankle weights, but now that they were off his speed had dramatically increased. Even though they were only at 20% strength their speed had scaled appropriately.

Kishin narrowed his eyes in focus and concentration doing his best to memorize every detail of Yoruichi's movements. Just as he was about to grab her shoulder she flexed her ankle to apply some strength at the last second giving her a jerking boost to dash to the left just out of his reach. He smirked and could only inwardly praise her level of mastery in Hakuda and Hoho. He was about to chase after her when he noted that she had dashed behind a giant boulder.

"That won't save you Yoruichi-san."

"We'll see ab-"

Before she could finish her response she noticed Kishin appear above her in the air. As he was falling down towards her she grinned and said, "You made a mistake heading in the air. It'll slow you by a ta-"

Once again she couldn't finish her sentence as she widened her eyes at the realization of what Kishin was doing.

He smirked and threw the pebble in his hand straight at her. She could only clench her teeth and dash back to dodge. That gave Kishin the time he needed to step on top of the large rock she had hid behind and flexed his leg muscles. The veins on his leg muscles contracted from his preparation to leap. Just as Yoruichi found her footing again from dashing backwards, Kishin threw another pebble at her causing her to frown and perform a flip to the side. That was the chance Kishin was waiting for as he finally kicked off of the rock formation right as Yoruichi was midair.

BOOM!

The top of the rock formation cracked and crumbled from his forceful push off of it. A wave of wind was left behind in his trail as he shot through the air at an incredible speed. Yoruichi felt her heart pound in shock and slightly in panic at his speed. Just as Kishin stretched out his right arm to grab her balled up form from her flip, she grinned and stretched out her body horizontally.

FWIP!

The sound of his hand swiping through the air falling just a tad beneath her arched back missing just by a hair's breadth could be heard. He was moving too fast to completely stop so he could only continue to move forward in motion. About a second later they both landed on the ground at the same time standing approximately 5 meters apart. A bead of nervous sweat dripped down the side of Yoruichi's head as she commented, "You almost got me."

Kishin huffed and stared at her in seriousness. "I'm surprised you were able to react like you did."

She just stared warily at him and said, "What's with the pebbles? Isn't that cheating?"

Kishin just grinned as a mischievous glint flashed by in his eyes. "There were no rules against it."

She could only click her tongue at his answer. "Tch. Damn you."

He just let out a light chuckle. "Hahaha, don't be like that. You set the rules."

"Oi oi, be a little more honorable will ya?"

"Nope. You're the Flash Goddess Yoruichi. It's honorable enough that I'm only using pebbles to try and hinder you."

"Why does it seem like you're a natural at playing tricks when playing tag?"

"Do you have to ask? Your brother Yushiro loves to play tag. When I first started indulging him in the game I was never able to catch him. He wouldn't want to quit playing until I could tag him so I could only resort to tricks."

Yoruichi took a moment to imagine how Kishin and Yushiro's game of tag looked like in her head before letting out a laugh. "Bahahaha! I see. No wonder." She then got a bit more serious as she recalled his words. "You said that when you FIRST started. Does that mean that if you were to chase after Yushiro now that you wouldn't need to use these kinds of tricks."

His lips curled upwards in a slight smile as he smuggingly replied, "You tell me."

WHISH!

He instantly disappeared from his spot and went straight back to chasing Yoruichi. She simply furrowed her brow taking the challenge much more seriously now after realizing that not only was Kishin fast, but he would definitely pull some sort of trick again.

Bam!

Kishin slammed his hand on the ground just missing Yoruichi's smaller frame.

Swish! Whoosh!

Fwish! Fwoosh!

Their game of tag continued on. Time trickled down as only 10 minutes remained of their game before the hour was up. At this moment Kishin chased after Yoruichi towards the wall of the training ground, falling only a single step behind her and closing. Yoruichi clenched her teeth as she took note of a pebble aimed right at her back so she dashed up to avoid it. Kishin jumped up right after her. He stretched out his right arm to tag her chest, but she expertly spun horizontally midair to avoid being touched. He grinned and reached out with his left hand crossing underneath his stretched out right arm to tag her back, but she quickly responded by stretching out her leg and kicked off of the training ground wall.

Fwish! Bam!

The sound of his hand missing and of her loud kicking off the wall resonated in the giant room. Kishin quickly grabbed a pebble from his pocket and tossed it at Yoruichi who was almost on the ground. She gritted her teeth as the pebble honed in on her location. Just as it reached 5 inches in front of her face her foot touched the ground once more giving her a platform to pivot her body to dodge just in time. That was when Kishin used the wall as leverage kicking off of it straight for Yoruichi. This time the distance between them was short enough where the speed he gained from the boosted kick off the wall helped him close the distance near instantaneously. Yoruichi widened her eyes in shock as she didn't have enough time to dodge.

Tap!

Kishin grinned in triumph as he successfully gripped her shoulder, however before he could celebrate he heard Yoruichi say in the distance, "Onmitsu Hoho-Shiho #3: Utsusemi."

Kishin furrowed his brow as the Yoruichi he had gripped onto disappeared and was replaced with her beige colored neck warmer.

"Neat trick." He approvingly commented.

She grinned in the distance with a smile on her face. "You're the last one I want to hear about using tricks. Nice though huh? Want to learn?"

Kishin smirked. "Let me guess, I gotta catch you first."

Her eyes gleamed with playful mischief. "You know the drill."

Kishin glanced down once more at the beige neck warmer before a frustrated expression clouded over his eyes. Yoruichi noticed his disheartened mood and couldn't help wondering what was wrong.

"Oi, you oka-" Her eyes widened in shock as he threw the neck warmer in the air just far enough and level enough where it blocked her sight of him. This caused her to instantly lose track of where he was. Just then she took note of a pebble flying straight at her. She was about to dodge when she felt his presence behind her at the same time.

This kid! Damn him! He got me!

Left with no other options she dashed into the air, however Kishin grinned in real triumph this time and instantly dashed after her gripping her ankle in his hand.

Fwip!

"Seems like I caught you. Yoruichi-san."

She clicked her tongue in defeat as they fell back down to the ground. "Tch. You got me. I lowered my guard for just a split second because of your acting skills. I thought you had lost hope for a second."

Kishin stretched his legs and back as he replied, "Just because I can't catch you? How fragile do you think I am?"

She just shook her head in amusement and let out a satisfied sigh. "Haaaah. Alright. Well, since you caught me I'll agree to teach you Shunko. After having you chase me around for nearly an hour I can tell that your Hoho and Hakuda skills are satisfactorily sufficient."

"Thanks for the assessment."

"You're welcome. Oh, how's your Kido though? Just so you know if you want to truly master Shunko then you should at least be able to handle level 70's Kido spells."

Without directly answering Kishin simply said, "Bakudo #81: Danku."

Dun!

A giant transparent and rectangular barrier appeared near instantly before dissipating, surprising Yoruichi for a split second. She then proceeded to let out an amused laugh. "Hahaha! Well then, I guess I shouldn't have doubted you. But seriously though, you can perform 80's level Kido that effortlessly? Seems I've misunderstood your true capabilities."

Kishin just shrugged. "So, do I meet all your qualifications to learn Shunko now?"

Yoruichi grinned and nodded. "Alright. There shouldn't be any problems now, but there is one caveat."

"What is it?"

"Your reiatsu. It's not really elemental based. You see my reiatsu is sorta lightning affiliated. There are others in Soul Society who have elemental affiliated reiatsu like Toshiro who's reiatsu can permeate ice or the Captain Commander who's reiatsu has a fire element to it. You though...I don't really know how it'll affect you nor do I have any idea if learning Shunko will be of any use to you."

Kishin just waved his hand. "I mind as well try right? Who knows? It might work."

Yoruichi couldn't disagree so she shrugged her shoulders and nodded. "Then let's get started."
