A.N. There isn't really that much information about Kido, so I took some liberties in creating them here. Another thing to know, it is that I'm trying something different. Normally, I write extremely long chapters, but I wanted to see if it is better writing shorter chapters and trying to update a bit faster. And, thanks for reading.

The Kido: Pain or Pleasure?

Chapter One: The Kido

The moonlight shone upon the leaves littered ground of the Sixth division barracks. The night air was cool and refreshing, a soothing balm from the day's heat. Renji breathed deeply, inhaling in the earthly scent of the woods, and tried to capture the moon's rays in his lungs. He was sore. It felt like a never-ending loop between being hurt and being healthy. However, Renji had come to accept it in his years of being a shinigami and from his days on the streets of Rukongai.

Sometimes, he cursed the fact he ever met Kurosaki Ichigo. After their confrontation, it seemed Soul Society was caught in battle after battle; first, the fiasco with Ichigo; secondly, with Aizen turning traitor and his band of merry villainous captains, and then with the Arrancar, and Espadas. Not to mention the Zanpakuto rebellion as well as the other countless problems that propped up. And, of course, all of this had to occur on top of their usual duties of paperwork and regular hollows.

Although the problems with Aizen and the Espadas were still going on, at least he could rest for a bit. Renji didn't think he'll ever get a peaceful rest until the war was over; every shinigami was in war mode after all, but hey, what could he do about it? He had to perform his duty as was expected of him, being the fuku-taicho of the Sixth division. The only good thing that seemed to come about the whole mess was getting Rukia back, and being on better terms with his taicho.

Lounging comfortably on the wooden platform in front of his rooms, he stared adoringly at the brilliant moon. Kuchiki Byakuya, Sixth division taicho and the twenty-eighth head of the Kuchiki line.

Cold. Beautiful. Brilliant. Unattainable. Just like the moon. It's no wonder taicho told me that fable, Renji thought. Then again, it's not different from what I thought before. Expect, I always thought of myself as the stray dog, not a monkey. Wonder if it's 'cause of my zanpakuto?

Shaking away his thoughts, Renji stood up. He felt like going on a nighttime walk. It was something he enjoyed, and in some ways, it kind of reminded him of the times in Rukongai district seventy-eight. Renji winched. He had just finished a battle with a particular tricky hollow a few days ago, and he still wasn't completely recovered. It was hard because the hollow had the ability to drain reiryoku. Fourth division had ordered him to rest for a week. By then, his physical injuries would be healed but his reiryoku wouldn't be back yet.

Renji estimated that it would take another week for his reiryoku to return to its former levels. In the meantime, it meant he was more hungry than normal. It also meant more paperwork instead of training sessions with his division.

Slowing down to a standstill in the Sixth division training grounds, Renji debated whether or not he felt like getting a snack from the kitchens. It was late, but there should still be people up. Then again, he also had some snacks from the Real world in his rooms that he been meaning to try.

His ears perked up when he heard a faint whistling sound. Placing a hand on his zanpakuto, he glanced around. It appeared that no one was there with him. He wrapped his hand around his sword lovingly. Even, if he couldn't get Zabimaru to transform into its shikai or bankai state; he felt safer having it with him. He was about to continue walking when he snapped his head up again. He could have sworn he heard something. Renji looked around him. Everything in his instincts was screaming that something was wrong. He'll be a fool if he didn't listen to his gut-instincts. It helped him in Inuzari, and it continued to help him in his duty as a shinigami.

"Who's there?" His voice rang out sharply in the night air.

His eyes caught a flash of black and he quickly brought up his sword in defense. The man didn't answer and continued to duel with Renji, seemingly content with just sword play. As Renji parried with another hit, he ducked as another man arose out of nowhere and attacked him as well. Pushing hard, he forced the first man back and kicked the second one to his right.

Panting hard, his body screamed in protest at the sudden physical activity. "The fuck? There's more of you? What the hell do you want?"

Renji knew that he could defeat the five men with just his sword if he moved quickly enough. Their skill level wasn't that high. The men didn't answer him, and just went into attack mode. He growled. As a fuku-taicho, he knew exactly what he was up against. One of the duties of fuku-taicho was the ability to assess the battle skills, strength and weaknesses of a shinigami quickly in order to teach and assign appropriate missions. Not to mention, everyone should have some knowledge of assessment in order to combat their opponents effectively.

Throwing himself into the fight, he defended and attacked his opponents as fast as he could. Renji knew his kido wasn't that good, and his reiryoku wasn't high, but he had enough power for some low level ones. The beginning of one was on the tip of his tongue when suddenly all of his opponents dropped dead to the ground.

He stopped and scratched his head in puzzlement. Carefully, he leaned down and examined one of the men, and felt his pulse. There was no beat. Renji brought his hand up to the man's mouth and nose, but there was no air. Every single one of the men was dead, and he had no clue why. He was about to summon a hell butterfly when all of the sudden his hair tie was pulled loose, and his long locks cascaded down his shoulders and back.

Renji immediately leaped away.

"You look even more lovely with your hair down. I don't know why you put it up."

The man smirked as he held a single black ribbon in his hand.

"What'd ya want? Did you kill those men?"

"Renji, you have forgotten me, haven't you?" the man sighed. "As to the men, of course, I had to kill them. They failed, didn't they? I bet you are wondering how, right? What do I mean right? You do, I can see that look in your face. It's simple really; I placed a hado on them. The second they were about to lose, I just trigger the effect, and what you see is what you get. But, you should know this, Renji. After all, you were victim to my hado before. Well, one of them anyways."

"Victim?" questioned Renji. "What are you talking about? Who the hell are you?"

"Perhaps, it is my new appearance. You did meet me several years ago when I was fat, and slow, and weak. Back in Rukongai. Shall I refresh your memory? My name is Hiroki Katashi."

Renji bristled with anger at the name. "Hiroki. Don't call me that. I never gave you permission to use my name. Sure, I remember you, not that I want to; you're the owner of that brothel in Inuzari. You're the fucker that tried to kidnapped Rukia and sell her into slavery. You're the fucker that steals kids off the streets and forces them into prostitution."

"And you're," retorted Hiroki, "the fucker who stopped me from getting that girl, Rukia you say? Did you enjoy my hado spell?"

"Hell no. Who created it? I know it's not you," he spat. "Yer too dumb to come up with something like that."

Hiroki toyed with the slip of ribbon in his hand. "It seems that you are still a virgin, Renji. That just makes the game more fun. Your reitasu's pattern indicates that you didn't have sex with someone to stop the spell. Ah, well. The first time is always the easiest. You must have been in tremendous pain for those months while under the spell. But, Renji…"

Renji didn't want to listen anymore. He ran and brought his sword down. His sword clanged loudly crashing into another sword. "What the?" He muttered.

"You did not think I would return to find you, without learning some new tricks, did you?" Hiroki ran a hand through his short raven locks and slashed his sword downward.

The two pitted themselves against each other in a fierce battle.

"I made a promise to myself all those years ago that I would have you. You ruined me, did you know that?" Hiroki launched himself off a tree, and strike with his sword.

"No," Renji braced himself, and shoved back, trying to angle another hit. "And do I care? Nope."

"Because of you, I lost that girl. And, because I lost that girl, I lost the biggest deal I had with the gang. I lost my brothel because of that."

Renji gritted his teeth. "Bastard. Good riddance to scum like you."

"You saving that girl were a good thing though. You are very beautiful even back then. You caught my attention."

Hiroki caught a hold of Renji's sword and flung it away. Renji started to shupon away, he was weak and tired. He could only rely on so much adrenaline before the pain started to take over. He just knew that if he wasn't injured, he could do much better and there wasn't much he could do with his limited reiryoku.

Hiroki grasped Renji's wrist with his right, and pulled him closer. "I could have sold you once, and be set for a long, long time. The almost feminine appearance with hair of blood likes yours; I could have, wanted to, but I never found you or that girl again."

Renji started to kick out with his leg, but Hiroki just pinned him down. "I heard news of an exceptional fuku-taicho with red hair, and I knew it must be you. Even then, you had some reiatsu. You've changed, of course. More muscular, and stronger. Very masculine. A fierce temper, but you still have long hair. The tattoos are new, rather refreshing. I would enjoy breaking you and making you pay for ruining me."

"No way in hell am I going to let you do a thing to me," gritted out Renji. He struggled beneath the weight of the man, and was almost free when a whispered Hainawa entrapped him.

Hiroki grabbed a hold of Renji's chin and forced him to look him in the eye. "Did you know, Renji, that I still know how to perform the Hado spell? Only I've perfected the casting. I tested it out several times, and I found out that if a person was attacked by it again, the spell strengthens and with each continual spell, it causes more pain and the need for sexual pleasure."

Renji spit into Hiroki's face. "You sick fuck."

Wiping his face in disgust, Hiroki said, "You shall pay for your insolence. Forbidden Hado seventy-two: GakuKutsuu."

Renji immediately wriggled in pain. It was worse than his current pains. It was just like before, his body struggling in discomfort and torture. The spell was directly linked to his body's nerves or spiritrons. Trying to hold onto the present, he exerted as much reitasu as he could, breaking the Hainawa encircling him. He crawled on his knees, trying to get away from Hiroki.

"I think one more time should intensify things more," spoke Hiroki darkly. As he casted it again, Renji fell against the ground, trussing around as he tried to maintain mind over body. Hiroki grabbed Renji in his arms, as one of the sleeves of his white yukata slid down a muscular shoulder. Roughly, he grabbed Renji's head, and kissed him cruelly, biting down savagely.

He stroked the red silken locks, and brushed a finger over Renji's cheek. "You remember what happen last time, don't you? Pain so unbearable, that this kido can only be broken by intense pleasure. Intense pain followed with intense pleasure. Only sexual release and penetration by another can this end. The kido may have broken itself overtime for you. But, unluckily for you, you don't have that much time. How long can you endure such pain? The burning of your nerves, the torture of each painful gasp from even the lightest of touches; I will enjoy taking you and I won't grant you the release you need."

Hiroki slapped Renji hard and then shoved him down. Renji didn't move. Each motion set his nerves on fire, and all he could think and feel was the throbbing of pain. He groaned in pain. He struggled to move, but his body wasn't responding.

Damnit, Renji thought, must move.

He slid a hand down the dark markings on Renji's neck. The lovely contrast between black and golden tanned skin was almost sinful. Hiroki traced the markings down his chest, stopping just above the knot of Renji's obi.

He arranged Renji on his knees after shoving his shoulders down, and pulled up the yukata. He hastily undid the red fudoshi and tied it around Renji's wrists. Eyes gleaming with lust, he grabbed the firm buttocks and parted its cheeks. Hiroki squeezed the red-head's hips hard, causing Renji to scream in pain from being overly sensitive. With his other hand, he closed Renji's mouth, muffling his screams.

As he undid his pants, and prepared himself to thrust in, he stopped. Sweat dripped down his spine, as he felt hard, cool steel pressed lightly against his neck.

"Cease your actions immediately," ordered Kuchiki Byakuya, his grey eyes glinting with anger.
