Demon King Who Will Rule the Infinite Worlds

The fifth day of the festival 

"Minato Namikaze of Konoha versus Killer Bee of Kumogakure!!!" 

Enma approached the front of the benches, yawning and stretching his arms, "Is this why you brought me out?" 

"Yup, this is a crucial fight," Kushina dragged him into the stalls, waving at Jiraiya and the Third Hokage, who were there. 

...Arena, 

"I heard about you Yellow Flash, you battle like lightning and slash, slash, slash," Killer Bee smiled, drawing out two swords, "I will not underestimate you! You get that!" 

"Uh..." Minato massaged the back of his head. "Sure...?" 

"THREE" 

"TWO" 

Minato took out the tri-bladed kunai as Killer Bee prepared to battle.

"ONE"

"FIGHT"

Bang!

BOOOOOOOOMMMMMMM!!!

"AAAANNNDDDD~!!! HERE~!!!! IS THE NUMBER ONE HOT BLOODY BOY FROM KUMOGAKURE!!! THE AMAZING SONG STEALING STREETPERFORMING FREESTYLING MASTER KIIIIILLLLEER~!!! BUUUEEEEE~!!!" 

Killer Bee raced forward, closing the gap between him and Minato while dodging the approaching kunai. As soon as he dodged the first, he noticed the second one was immediately behind him. He smashed the kunai with the blade of his sword and turned on his heels to find Minato rushing around him with the two remaining kunais, moving at lightning speed, one of them charging at his neck, which he had to block again.

"You're good, but you don't compare to me!"

Minato moved out of the path and went after Killer Bee's body, stabbing, slicing, cutting, but he evaded, blocked, or parried every assault, saying, "Your blades! Can't get to me!"

Bee stopped running and brought one blade in front of him, blocking the strike while kicking him in the abdomen. The Yellow Flash flew away, rolled on the ground, and smoke erupted where he was. Bee tensed as a log rolled out. He looked around, hearing Eight Tails' voice. 

(Behind you!) 

Bee froze, feeling the palm on his back. He looked over and saw the Yellow Flash of Konoha standing there with a smirk, indicating that he could have murdered him, "Surrender." 

"No way~ Not happening~ I have a couple moves you see!" A red chakra emerged around Bee's body, and the tail made from the destructive chakra swiped towards Minato, forcing him to move aside. 

Bee chuckled, "I told you that your blades can't reach me! They are not good enough for a Kumo ninja like me!"

"Tch!" Minato's eyes widened as the crimson chakra formed claws around Killer Bee's arm. He moved out of the way as one claw cut the ground, creating a crater. 

"Tailed Beast Cloak," Minato said, narrowing his eyes. Killer Bee lunged at him as he vanished and reappeared behind his back, wind swirling around his hand, building a destructive ball of wind chakra, "Rasengan!!" 

The tails suddenly multiplied, and the red chakra thickened, protecting Killer Bee from the Rasengan and slamming him into the earth, making the gigantic crater via pure force. 

COUGH

Killer Bee coughed out blood, fleeing at the first opportunity and attempting to seize the blade. 

(He's too fast; you can't defeat him with only this!) 

"I understand, yet I am unable to transform." 

(Go ahead, transform; the barrier can withstand it.) 

Killer Bee froze up again, hearing the King's voice in his thoughts, just as he had heard Eight Tails, Gyuki. He smiled, pointing at Minato, "Now you will know why I am the Perfect Jinchuriki!" 

Massive smoke erupted around Killer Bee, and what emerged caused Minato to take a step back. It was not human. The beast had eight tails. It had an ox's head, a demon's torso, and eight octopus tails. "COME! YELLOW FLASH!" 

"Isn't that going too far?" Minato asked, wryly smiling. His palms became sweaty when he saw the Eight Tailed Beasts. The tails slammed down all around him, shattering the ground and tearing up the battlefield.

Minato flung unique kunai over the battlefield, which were marked with his seal. He teleported from one location to another, leaving a yellow flash over the arena. He looked at the barrier, not even shaking despite all the damage. 

He glanced at the beast in front of him, recalling what had happened last night, "Twice in one day." 

.

..Guest House 

Minato entered the home, having returned from his appointment with Jiraiya-sensei and the Third Hokage. Kushina went before him, exhausted from the long day.

"Hmm?" he hesitated and went directly to the bedroom, hearing the sound of the shower. The door was slightly open, and the room was dark save for the light in the bathroom. When he looked in, his heart raced because he couldn't see anything but her wet skin and the silhouette of her naked body under the running water, with her fingers rubbing her soft pink nipples, her back arched and her eyes closed, her hips slightly pushed forward, and her mouth parted to moan.

Her fingers dipped down to her hot pussy, where she placed her finger against the opening and pressed it within, making her moan louder. He swallowed, hearing her screams as he shoved her back against the wall, and she slipped two fingers inside, feeling her up, and groaning loudly, "Mmmm..."

Her finger dug inside her, pressing deeper. She wanted it, but she was already wet. Her pussy was wet from the water, and her excitement was "Kushina?" 

"Minato..." 

He felt his heart stop when he saw the wanting, racy look in her eyes. She began thrusting her finger deep within her. He got into the bathtub and could see what she was doing much better. She sighed as she moved her hand over her chest, playing with her breast as her hand began to move quicker, "Minato...Ahhhn..."

She arched her back and exclaimed, "Minato..."

Her fingers moved quicker and faster. Minato embraced her from the back, her breath caught in her throat as he wrapped his arms around her, reaching out and toying with her breast and clitoris. When she pressed her fingers, she opened her mouth and exclaimed, "AHN!!!"

Her hips trembled as she shoved herself against the wall, shivering. Her legs were shaking so violently that they couldn't support her as the water washed away her juices, but there was still cum on her fingers as she pulled out.

She panted and raised her hand, which was drenched with her fluids. She placed her fingers on Minato's lips, and he opened his mouth, allowing her juices to pour onto his tongue before closing his mouth around her fingers. He began licking her fingers, and her eyelids fluttered open to reveal his blue eyes, full with lust for her and staring at her in pure love.

"Mmm," she arched her back as his fingers reached between her legs. She had missed it. After her initial encounter with Kurama, she grew horny whenever she used Nine-Tailed Fox's chakra. For several days, she became the King's bitch, spreading her legs for him and his men while being schooled by them all. This is what she missed: Minato's warmth of love for her, and hers for him. 

She grabbed his hand, and the shower stopped. He carried her into the bedroom and carefully placed her on the bed as she pulled him in for a kiss; he crushed his lips against her soft lips as she groaned into the kiss. When Kushina stared at his stiff cock, he pulled out and got rid of his clothing as quickly as he could; seeing him naked after all this time made her aroused and horny. She longed to feel his cock buried inside of her.

She twisted around in the bed and crawled, arching her hips and thrusting her ass up to Minato. He crouched down and stared at the folds of her wet pussy before reaching forward with his tongue and lapping at her insides while gripping her hips.

"Ah! Aaahn!" Kushina gripped onto the sheets, swaying her hips with Minato's tongue moving in her pussy, "M-Minato !!!"

He sucked on the folds of her pussy and placed his fingers against her hot entrance, making her shudder. He reached up and pulled out his fingers, and she rose her hips, wiggling her ass. She pulled her ass cheeks wide with one hand, presenting herself to him as the other gripped the sheets, her wet lips twitching and her hips shaking. "Minato...hurry...fuck me...put your cock inside of me..."

Her tongue stuck out of her mouth, drool dripping down the corners as he pressed his hard cock between her ass cheeks. Her legs shook and she bit the sheets as he rubbed his cock, up and down, his pre-cum mixing in with her juice. Her hips bucked against his cock, her soft cheeks squeezing his cock as he pressed the head of his cock on her wet opening.

He shoved his cock into Kushina, making her shiver. His thick cock filled her as she threw her head back, arched her hips, groaning from her pussy being penetrated after all this time. "Ahn! Minato!! Minato~!!! MMMMM~!!! MMMM!!! Minato!!!"

"Ahn! Kushina!!" Minato grasped her ass and shoved his cock deep inside her pussy, filling her as his cock hit her insides, stretching them as she became wetter, making it easier for him to thrust in and out. His hips slammed against her ass, and her secretions coated his cock as he pulled away.

"Ahhh! Minato!" her wet folds spread apart from his rigid cock that emerged. Minato slid in, and Kushina followed his thrust with her hips as they pushed deep within her pussy again, "Ahn~!!! Mmmnnnn~!!!"

His thick cock pushed against her delicate walls, and she couldn't help but groan, her tongue rolling out of her lips as she drooled, swaying her hips as the bed creaked. She trembled with ecstasy, his firm cock slamming deeper as the bed shook. Her delicate breasts jumped with every push. Her legs shook with delight, and she gripped her hands around the sheets as his cock pounded on her sensitive areas, causing her to stiffen up.

She was concerned that he would be able to determine how much her pussy had been spread by the Kings cock and how many times she had been filled with come. It would be quite humiliating. Her eyes rolled back with delight as she began squirting all over the covers and wiggling her hips.

He grabbed her thighs when her hips jerked. As she pressed her face into the cushion and shouted, a rush of ecstasy flooded her body. Minato was filling her out. His powerful cock entered her, and his warm cum spread through her pussy. The climax that raced through her body left her numb, 'I finally belong to Minato again...' 

Minato leaned forward, and she turned over to face him as he mashed his lips against her soft ones and clasped her boobs. 

"Mmmmm..." they exchanged passionate kisses, and she moaned in between. They parted with the sweetest smile on her face: "I missed you, Minato..."

"I am delighted you are back," Minato hugged her as they lay down on the bed. Kushina closed her eyes and buried her face into his neck. She could still feel it, as if the King's phantom was present, fucking her while Minato was unable to see or feel. It was all really vivid. 

She separated herself from Minato, who had followed her into the bath. The hot water flooded her body when Minato joined her, his chest against her back and his lips pressing into the crook of her neck, "What is it...?"

"The training wasn't easy...I'd never been away from you for so long...and," Kushina stroked his palm, "I watched Nine-Tails pass...Minato...do you think Nine-Tails is a monster?" 

"It is complicated." 

Kushina muttered, "I want to hear it," as water splattered on their bodies. 

"I think...we have no choice. When Lord Hashirama thought about making these villages, he knew others would follow, and the fight between clans would turn into a fight between villages. But he was confident that with Madara Uchiha by his side, the two of them could stop all wars and force people into a certain peace." 

"But because they were too strong, it may lead to other towns creating a treaty to fight against them. That's why he chose Tailed Beasts: to maintain a balance of strength among the villages, and make the strongest communities unbreakable by the lesser ones, so there was some stability and hierarchy." 

"We had to seal the Tailed Beasts for that...no one could have predicted that Marada would betray Lord First...and after that fight, Lord First passed away, breaking the balance. Even then, it was the Jinchuriki who allowed a semblance of balance to remain. It doesn't change that we sealed them...and now if the tailed beasts are released, they will attack the village. Maybe...the First thought that the Jinchuriki could reach an agreement with the Tailed Beasts...take on 

"All I know is that I will fight to safeguard the village, no matter how wrong we are in this. I will defend our home." 

"Minato, if you had been the Jinchuriki instead of me, you might have understood him without anyone's help." 

"I'm not sure about that..." Minato shook his head. "Did you...come to an understanding?" 

"I did...in tomorrow's battle...I'll help you." 

"How..."

"I'm going to instill a piece of Kurama in you." 

"How...?" Minato asked, raising his eyebrows. He had been studying seals to ensure Kushina's safety in case anything went wrong. He even considered separating Kyuubi. "Wait...Kurama? Is that Nine Tails' name?" 

Kushina chuckled and nodded, "It is." 

"What exactly happened?" 

Kushina parted her lips to speak when Kurama's voice rang in her ear. She helplessly laughed, "He says. Do you want his power or not? If you do, don't ask." 

"Now I'm even more inquisitive." 

"I'll tell you someday..."

Arena, Present 

Minato teleported behind Eight Tails, grasping the special kunai with his left hand and making a Rasengan with his right. "Kurama, I need your chakra!" 

(Tsk!) 

Minato smiled as he felt the huge chakra running through his veins and strengthening the Rasengan in his grasp. It rose to the size of half his body, contributing to the devastating spinning in the just. The air shuddered with the sheer might of the Jutsu, "Rasengan!!!" 

He slammed the Rasengan into Eight Tails' back, causing tremendous shockwaves to slam him across the battlefield until he collided with the barrier, eliciting screams and gasps of dread. Eight Tails fell to the ground, attempting to stand up, but Minato appeared above him, snatching the Kunai he used to teleport, "FLYING RASENGAN!!!" 

The wind chakra surged around his hand, the spiralling wind forming a vortex in his hand as he slammed his palm. The Rasengan exploded with wind, causing a storm of destruction on Eight Tails' body, forming the crater, with the chakra surging around Eight Tails slamming him deep inside the crater, forming another layer of sunken earth. 

Aae got up in the stands and yelled, "BEE!!" They had come across the Yellow Flash on the battlefield, and he was truly strong, but he hadn't transformed yet. When they saw Bee transform, they were confident that he could defeat even the Yellow Flash of Konoha, but instead, he had become a bigger target. 

The audience erupted in cheers again.

Bang, bang, bang!!!

Killer Bee removed his Tailed Beasts metamorphosis to flee Minato, but Minato would not give him time to breathe, appearing behind him with his kunai on his neck and saying, "Give up." 

Bee giggled, "Yeah, I can't beat you. Was that Nine Tails chakra in you?""

The referee charged onto the field, "KILLER BEE HAS GIVEN UP!!!! MINATO NAMIKAZE OF KONOHA HAS WON THIS BATTLE!!"

The crowd erupted in cheers, and Minato nodded to Killer Bee, "It was." 

When Minato returned to the stands after his bout, Third Raikage stood up and marched straight to King's box. Minato was trying not to use it, and for good reason: he knew how this would end. 

"Now, how will King manage that?Jiraiya lifted his eyebrows. 

"How is he going to manage what? That Minato triumphed," Kushina hung on Minato in the work, smiled at his victory. There had been moments, too many times, when she was worried about him, but now she didn't need to, not with his newfound power, which could even defeat the Tailed Beasts. 

"No, what happened there? What occurred while I was busy?" Enma rubbed his cheek, 'crap. It entirely escaped me that he had other plans operating concurrently. 

The Royal Viewing Box 

"I thought we had formed an alliance!" The Third Raikage marched into the room, seething with rage. 

"Yes, we did." "We do," King Aurum said, welcoming him to take his seat, but Third Raikage didn't hear anything. 

"Then what was that? You planned this! Do not tell me you didn't! Until yesterday, Minato Namikaze lacked the Nine Tailed Beast's powers!" 

"I trained Kushina. Helped her get control of Kyuubi's abilities. She shared it with her boyfriend is her business," Aurum Light stated. "It turned out amazing, if you ask me." 

"Why?" The Third Raikage narrowed his eyes, wrath rising inside him. 

"Because I do not want to see this land controlled under a single name. If that's what I wanted, I'd done it myself. I merely want the war to stop. Your weapons have reached Third Generation, and I can see how some of your village's clans are already selling them to smaller villages, upsetting the balance." Aurum switched his gaze to the Arena, looking at the spectators. 

"Did you think if you just sent them to the other side of the continent, I wouldn't know?" Aurum looked back out of the corner of his eye, "I told you. Trust is important to me. I asked for faith, and I gave it to you unconditionally." 

"We did not have an option in this situation! Daimyo made the agreement!" 

"Isn't this why your Daimyo is here? I'm sure his perspective on the topic would change after viewing the tournament. Don't you?" 

"Haha...hahahahaha..HAHAHAH!!!" Third Raikage burst out laughing, gripping his fist and gritting his teeth. "I underestimated you! You want to terrify the daimyo! Then defeat me! He believes in nothing but my strength! Do you dare to? King!" 

"You're so predictable, Raikage," Aurum rose up from the Throne, "Come. I'll show you why I'm the King. 

.

.

.

"Tifa and Cloud! Aerith!" Kushina waved her hand, expecting them to be in the stands, but they were standing right under the two boxes, one for the Daimyos and the other for the King. Because the Daimyos' boxes were more of private rooms for them to have fun, they didn't mind that theirs was below the King's box. 

"Kushina," Tifa waved her hand. "Congratulations on your triumph, Sir Minato." 

Thank you. It was thanks to Kurama and Kushina. In that way, I cheated," Minato said with a bright smile, pointing skyward. "How is everything?" 

"That's the craziest thing he could have done," Cloud said, leaning against the door to the stairs leading to the box and nodding towards the battlefield. 

"Wow, I feel so horrible that maybe I shouldn't witness this," Tifa hesitantly remarked as she picked up the popcorn she intended to share with Aerith and Jessie, but they were nowhere to be found. 

"Yeah, you really are playing the part," Cloud rolled his eyes at her, prompting a grin in response. 

Minato light chuckled as he watched Third Raikage and King approach the Arena among the shouting audience. 

"I'm not sure it would be that simple. The Third Raikage is said to be the strongest shield and spear. 

"That doesn't matter to His Majesty. I think. Cloud, have you ever seen him fight?" 

"No. I know Arthur and I were never able to score a hit against him." 

"Where's Arthur?"" 

"Who knows?" 

.

.

.

"King Aurum," Enma glanced at the guy standing opposite Third Raikage. The thick tension filled the air as they peered into each other's eyes. "Can he beat Third Raikage?"" 

"Of course he can," Aerith drew Enma closer, his body draped over hers; she reached out to grip his head behind her, "it's just a matter of how much strength he utilizes." He'd like to make a show of it." 

"THREE! TWO! ONE! START!!!!"

"Third Raikage." I had high hopes for this area," Aurum exhaled, the air swirling about him, his snow-white hair swinging with the breeze. 

"Enough talking! We'll chat to our first!" Third Raikage wrapped his body in Thunder Chakra, and his Lightning Cloak appeared, enveloping him in electric currents. "Let us begin! KING!!!!"

"You're underestimating me. For your advantage. I shall only employ these continents' powers. You call them jutsu?"Aurum gazed at his palm, "Rasengan." 

An sphere of wind appeared on the top of Aurum's hand, startling the Third Raikage and the Konoha ninja in the crowd. "Did you learn that from witnessing it?"The Third Raikage's eyes opened, not expecting to see that Jutsu in King's palm. His surprise did not last long, "that Jutsu will not aid you against me! I refined my physique with thunder and lightning! A thousand Jutsu cannot destroy my body! Not even the trump card of Tailed Beasts could deliver any damage! A small Rasengan is nothing!" 

"You do not see what I see. This Land and My Land follow different practices. We all have something to offer one other. For starters. This jutsu. It's an amazing Jutsu with many possibilities. "All I need to do is increase the rotation of this Jutsu," Aurum focused on the Rasengan, which became smaller and smaller, while the surrounding air became wilder until it was smaller than a pea. 

"No, how is he doing that?Minato grasped the railing as he sensed Rasengan's danger. 

"Then you add enough chakra to increase its size despite the density," Even as he said, the size of Rasengan in his hands continued to grow, looking the same as the normal Rasengan, but the force inside it surpassed even the Tailed Beast Bomb that Third Raikage had seen. The land around the King caved under the weight of the Jutsu, the wild air raged, and the Lightning Cloak pushed the air away.

"And then, you change its Nature," Aurum narrowed his eyes, seeing the translucent palm appear above the Rasengan, touching it. For a moment, the rotation inside it slowed down, about to fall apart, forcing him to speed it up, turning the Rasengan black, swallowing light itself, leaving a teal boundary. 

With the development of the Rasengan came a peculiar silence, and the Third Raikage nearly fell to his knees, unable to breathe properly. The Rasengan had already sucked up all the wind around them, leaving them breathless, and gravity drew him towards the Earth, pulling him from every side. 

When the heavy Rasengan flew through the air, brushing past his shoulder, he leaped to the side, appearing near the wall of the arena, only to realise he had become light. He looked towards his left arm, which had disappeared, still falling to the ground where he was standing, missing a large part of it, and a few steps away was the King, who caught the Rasengan thrown at him. 

The King tossed the Rasengan into the sky, where it floated up and expanded, causing the barriers to quake from its tremendous weight and pressure. It continued to grow until it exploded with light, leaving an afterimage of the Jutsu in the air. 

The Rasengan shattered into numerous pieces that fell over the audience, the arena, and the hamlet, smashing everything they came into contact with. The shards multiplied the destruction until they were nothing more than a shower of destruction.

When the air returned to the arena, the pressure changed, and Third Raikage noticed blood gushing out of his shoulder. 

"Father!" Aae and Bee almost raced into the arena, barely holding themselves back. 

"STOP!!! Third Raikage yelled, sealing his wound and glared at the King, who stood feet away from him, looking down to meet his gaze.

Aurum took out a purple orb from his left pocket, "A Materia from our side. That is all it took to add Gravity to Rasengan to break through your strongest shield." He walked towards Third Raikage, looked at the man kneeling in front of him, "I told you. I don't want to crush this land and rebuild it in my own image. I didn't want to paint it into a single colour. I gave you a chance and my trust." 

Aurum knelt in front of Third Raikage until they could see eye to eye: "Do not try my patience and kindness. Third, if I march, I will rain hell on this land. I will destroy everything that dares to raise their head. You want me quiet." 

He narrowed his crystal blue eyes and said, "If you wish otherwise, you'll all have to disappear." 

His stern expression transformed to a smile as he stroked Third Raikage's shoulder, causing another translucent palm to emerge over his, this time with a green hue. It returned the Raikage's hand, which had been lost to his jutsu. "Then again, I trust you will chose wisely." 

"You," Third Raikage lurched to his feet, startled at the sight of his hand. He stared at it for a few moments, coating his palm in chakra and concentrating massive lightning chakra in his fingertips, from five to four to one, "One Finger Assault." 

Third Raikage stared at the man, who didn't move or protect himself, instead looking back into his eyes, waiting for his next move. He swiped his palm not at the King, but at himself, slashing the arm that the King had graciously restored. 

His arm plummeted to the ground amid the crowd's terrified shouts, "We tried to break the pact first; this is my response to you." 

He walked away from the king. Aae and Bee attempted to help him, but he hmph'd, "I lost my hand! Not my feet!" 

Aurum grinned, "That's why. I don't want this land to lose its inhabitants and personality; if there was only one hue in the world, it wouldn't be fun." 

.

"Minato! Minato! That was your Rasengan!" Kushina jerked Minato back and forth, unable to comprehend what she had witnessed. 

"That is Rasengan...but..." Minato stared blankly at the point where he saw Rasengan being altered. Even if he possessed Kurama's chakra, he could make it that dense, but it would take some practice with the rotation portion, and there was the shift in chakra nature that he had not yet mastered. It would take years to achieve the same level, "even then...it won't be that powerful...what did he use to modify its nature with...?" 

"It should be gravity," Cloud has noticed the tug before. It was the same Graviga, "That's what he was displaying. We have a Materia called Graviga, which permits a Gravity sphere to develop; as long as you practice aura, anyone can do it, including you." 

"That's what he meant when he said we all have something to give," Minato softly laughed. "Isn't that more of a threat? We can make your Jutsu even stronger, so sign a pact with us or you won't be able to acquire Materia to develop your Rasengan?" 

"Is it?" Cloud asked, looking at Tifa, who giggled. 

"We will have Materia for sale. We are still in the middle of preparations, but it should open by the evening," Tifa blinked at Minato, comforting him, "Although. Graviga is an S-Rank Materia. Since His Majesty stole Rasengan, you can take it for free." 

"But Rasengan is only an A-Rank Jutsu," Minato said, raising his eyebrows. 

"Anyone can learn Rasengan. On the other hand, there will be only one Materia. Because we can have ten Rasengan users at one point, and you can only have one Graviga user at one point, you can buy three S-Rank Materia with one A-Rank Justu. I would recommend you take Books on Aura Training," Tifa spoke like a saleswoman, already setting the Materia before the shop opened. 

"I'll have to ask Third Hokage about it," Minato said, bowing and thanking her. He realized they needed to recuperate after what they witnessed. They came to observe how powerful Lady Senju's New Village was, but they were overwhelmed by King's strength, who could even tear apart the Strongest Shield, which a thousand ninja might not be able to crack as simply as tearing paper. Everything had changed. Leave alone... "Gravity..." 

"You want it, don't you, Minato," Kushina grabbed his palm, interlocking their fingers. "Don't worry, if that old man doesn't let you get it, I'll beat him up!" 

"No need," Minato said, stroking her head. His heart was filled with warmth; "I am sure Lord Third would agree." 

He has to. Without that Materia, no one can defeat that Jutsu.

'He's strong, but...' Enma looked at the ground where King was departing, and saw two lovely women-like beings hovering behind him, hugging him. It was just for a while, but he sensed others like them, flashing in the air, maintaining the barrier, and healing those who were harmed; 'what are those? Is this the source of his power? That is cheating.'
