Demon King Who Will Rule the Infinite Worlds

Avalanche, the ship had taken a six months round trip to Avalon, finally returning on the same day as the King's visit. While they were relaxing, enjoying the village that had changed beyond recognition, Tsunade was sitting in the programing room which had a super computer setup for Red Queen when she stayed here.

She stared at the Uchiha boy with black hair and black eyes sitting in front of the computer, writing a code in his language which she didn't understand. It took her a while to realise that there was a smile on her face when she saw him.

She caught herself doing that for some reason, "Who are you?"

"No one," Enma answered without missing a beat.

"I am getting married to him tomorrow."

Enma stopped typing. He looked towards her, thinking, "you are getting married? What about Jiraiya-sensei?"

"No matter what I say. He won't stay," Tsunade shook her head, "I asked him."

"Of course he won't..." Enma knew Jiraiya's motivation, "why him?"

"Until a year ago...I was only living because I survived, waiting to die one day. The moment I saw him...it's like we met in a completely different life," Tsunade couldn't explain, "it was love at first sight."

Enma rolled his chair towards her, looking at her lips. He leaned forward to kiss her lips, and she didn't resist, closing her eyes. He whispered, "what do you feel about me?"

"Familiar..." Tsunade opened her eyes, frowning, "who are you?"

"Do you love me?" Enma asked.

"No...?"

"Figured," Enma lowered his eyes, staring at her feet, "I saw them this morning..."

"Who?"

"His other wife."

"Eve, you mean?"

"Her, and...there was another guy with dark blue hair?"

"Augustus, her brother," Tsunade parted her lips, "Right. Augustus," she muttered, "you remind me of Aurum...and Augustus...?"

"Yeah? Me too," Enma looked at his palm, "Whatever I am...doesn't matter," he clenched his fist, thinking about Naoko and that girl Eve. He was always an experiment...a throwaway. Now he was a copy and he couldn't care less about it. But Naoko, "they'll pay for it."

Tsunade put the back of her palm in front of her and nose, coughing from the heavy, grating dark red aura coming off from Enma. It was suffocating, nauseous, and it made her cough.

"Ok, stop."

Enma felt a palm on his shoulder, feeling the room turn bright. He slowly blinked, looking at Tsunade on her knee, coughing, "W-what...sorry," he helped her up, helping her sit on the chair.

Tsunade looked past Enma, towards her future husband, the King, who stood behind Enma. He reached out, and she took his hand, getting pulled in a hug. She felt much better in his arms, especially since he made her feel like a woman like no other.

"What is going on here?" Tsunade softly coughed, feeling warmth from the fumes of Aurum's aura that purified the aura in her body.

"Nothing I can't deal with," he promised, "You too, Enma. Calm down. Naoko is not what you should worry about."

"I know I am not from this world and all, and I am not even her true brother, but how can I not worry about her," Enma scoffed, sitting back down, "You should know it best."

"I know," Aurum stroked Tsunade's back, warming her, "like I said it's nothing I can't take care of. What you should worry about is what you carry in your soul. They created it from the Blood of Ten Sovereigns."

"That again, what is that?" Enma frowned.

Aurum sat down where Tsunade was standing while she leaned against the table, feeling much better, wanting to hear what this was about, "Long, long ago. At the beginning of Demon World, when it was in chaos, Demons were born with great powers, destructive beings driven by desires. It was a living hell. That's when the Ten Sovereigns rose to power. They held such great power that they made 33 Heavens tremble in fear and forced Gods to come together and seal our very Existence and leave us harmless to 33 Heavens."

"Even then, they couldn't completely take away the powers of Ten Sovereigns who hid in the Mortal Realms, waiting to regain their powers. Once Two Godslayers appeared, the 33 Heavens created Abyss to keep them busy, but Abyss grew more intelligent. Instead of fighting Godslayers in a losing battle, it started hunting the mortal worlds, searching for the bloodline of Ten Sovereigns to grow in power."

"You," Aurum breathed out, "Carry the power of Ten Sovereigns, each could Rival a Godslayer. But there are only six of us and 10 of them. If...no, when they come back to life it's going to be an all out war."

"What do you mean when?" Tsunade crossed her arms, "Can't you stop it?"

"You can kill me," Enma muttered, "I won't fight."

Aurum looked at Enma, nearly smiling, "Ok, I see Augustus's dumbness now."

"You," Tsunade kicked his foot, giving him a look, telling him to be nice. She already felt bad about the kid and she didn't even know the whole story.

"I am just saying," Aurum chuckled, "Enma. Your soul came to this world. What happened to your body?"

Enma tensed up, "Oh shit," he closed his eyes, "We are fucked."

"Not exactly," Aurum keenly narrowed his eyes, "I do think we have a chance. I'll find the Ten Sovereigns. I doubt they'd be in a single universe. In that case. Defeat them and absorb their powers in those eyes of yours."

Enma raised his eyebrows, "Is there anything that you can't see?"

"You are too weak to hide it."

"Wow, you are annoying."

Tsunade darted her eyes between them. She walked away from this, "even from your standards. This is weird."

Aurum held her wrist, "Don't leave. I need you do something."

"What," Tsunade got pulled back in front of him, "seeing you talk to him like like seeing two shadow clones talk. It's tasteless and boring."

"I know," Aurum stood up beside her, slowly pulling off her kimono. She blushed in a hot shade of pink when her breasts popped out of her clothes, her big boobs in her lover's hand. Enma leaned forward, watching her large breasts sway in front of him.

"I need to teach him something, help me?" Aurum grabbed Tsunade's boob from below, and rubbed his finger on her hard, perky nipple. 

"This is stupid," Tsunade shook her head, "What are you even trying to teach him here?"

Aurum kissed her lips, pulling her closer to his body. She moaned in his mouth, her arousal increasing by the minute. 

His body made her feel so small and yet so protected in his arms. He placed her boob in front of Enma, "start by sucking on her boob."

Enma gave him an unsure look. He shrugged, putting his arm around Tsunade's waist, pulling her closer. He sucked on her nipple, nibbling on her perky nipple. Tsunade nibbled her lip. 

"Yes, now Tsunade, offer your aura to him," Aurum whispered. Tsunade grabbed the back of Enma's head, shoving his face in her large tits, moaning, "Are you serious?" she cried out as her aura pumped through her body. She put her aura through Enma's body, who responded in kind.

It felt good. So, so, good. She stroked the back of his head, his aura sank through her body, covering her from head to toe, making her so much more sensitive. Aurum felt her wetness against his fingers and her breasts grow firmer. Her pussy juiced as she arched her back, her boobs pushing against Enma's mouth.

"You are doing good," Aurum encouraged him, letting Enma work on Tsunade's nipple. He nibbled on her nipple and her breast, taking in the taste. He rubbed her erect nipple, flicking it. Tsunade moaned, and Enma squeezed her boob, teasing her nipples and her boob.

"Feels so good~" Tsunade's mouth fell open, her chest rising and falling. Her breathing was laboured and heavy, her chest was tight, and her pussy was burning and yearning for him. Her head rested on Aurum's shoulder, who whispered, "Now, Enma. Use Communication on her Aura."

Enma paused for a second. He didn't realise Aurum knew about that. He closed his eyes, feeling her lustful aura, and tried to communicate with her body and soul. She raised his face, locking their lips together in an openmouthed, tongue swirling kiss.

Tsunade's heart skipped a beat. She could feel him in her soul, connected by their lips, connected by her soul. Tsunade tried to close her thighs, but Aurum didn't allow that. He slapped her pussy, and Tsunade moaned, feeling his fingers between her legs.

"Now, for a second. I need you to focus on your Creation Rebirth: Strength of Hundred Technique."

Enma and Tsunade stopped, the connection between them broke in that moment as they both looked towards Aurum, "Seriously."

Aurum sighed, "Seriously. Aura allows us to impart knowledge, but you don't know how that works. Instead, Enma can use Communication to directly take that from Aura. All you need to do is focus on it."

"Just say that first," Tsunade rolled her eyes, "now that I know I'll teach him. No need for you to be here."

Aurum stepped towards her, which made her deflate in seconds. Especially when he cupped her mound and whispered in her ear, "when you are done, come to me."

Tsunade gulped, her mouth was going dry, her heart beating faster, and her pussy was getting so, so wet. Her heart skipped a beat. He kissed her and pulled away. She watched him turn and leave with a smile, "Ok..."

She could finally breathe once he left. She immediately shot a look at Enma, who was smirking, "You two are like cousins from the furthest branches who happened to be identical."

"Yeah, yeah, I guess so."

"Hm," Tsunade looked at him, almost judgemental, "You got the short end of the stick then."

"Great, I get to come to another world just so than I can live in my own shadow," Enma rolled his eyes, sliding back to the computer to work.

"When you put it like that," Tsunade took off the rest of her clothes, becoming naked. Enma noticed that, more so when she was walking towards him. She straddled him on the chair and pinned him down by his shoulders, looking at his lips, "I'll try my best to teach you."

"Because I am him...?"

Tsunade stroked his cheek, "You mind that?"

"A little...I'll take it."

"Hm," Enma opened his eyes from Tsunade's aura that he was drowning in. Before coming here, he had to stay at Mount Myoboku for a period. It helped him gain an all round sense of how Ninja fight and form his own fighting style in this world. It gave him time to learn many of the Genjutsu. He took all of Uchiha Techniques that Fugaku could give. His Byakugan and Sharingan also achieved Rank 5.

He also learned to hide his Demonic Aura under Abyssal Aura and Abyssal under Chakra and confuse it all with slight Natural Energy, and now.

[You gained Senju Physique (3)]

The was this rush of aura and chakra inside his body. It was different, powerful, like never before. He could feel an explosive amount of strength, his muscles were flexing on their own, his eyes and his body felt stronger, faster, better. His body had gained a sturdiness of its own.

Tsuande stroked his chest, noticing the slight change, "Focus," she reminded him and he did, using all the Abyssal Aura to guide all the Demonic Aura in one place. He put his arms around Tsunade's supple waist, weaving hand signs behind her back to perform Seal of Hundred Strength.

As long as the Seal of Hundred Strength didn't shatter, all would be fine. He knew if he let this demonic chakra rampage, it wouldn't end well for him. The aura was too violent, too dangerous, too unpredictable.

A reddish-purple mark started to form under his left eye, taking the shape of diamond that sucked in all the aura inside it. The seal was to store only a part of your everyday chakra to collect it for an emergency. Though, he planned to seal all of it, and use only a tiny bit of it necessary to maintain aura inside his body.

It took more than an hour to fully fill the seal with his aura, but the disappearance of Demonic Aura caused Abyssal Aura's side-effects come out. He furrowed his brows, hurriedly forming the Second Seal of Hundred Strength, right beside the Demonic Aura seal, taking away most of his Aybssal Aura, maintaining the balance between Demon and Abyss.

'I feel light...weaker,' he clenched his teeth, ignoring the shiver in his arms and body. Tsunade hugged him, healing him, granting him support after he abruptly lost. The absence of Abyssal Aura didn't mean it was gone. He still had Abyssal Aura under control, but the power that comes with it is gone, leaving him feeling weaker than before. The same went for the Demonic Aura.

But the feeling quickly disappeared as he started taking in Natural Energy at large, forming the third seal right below Abyssal Seal and Demonic Seal. From what he felt, they were half the size of the seal on Tsunade's forehead, 'I shouldn't look too dumb. I should find a way to hide them...'

He basked in the warmth of natural energy, storing it inside the third mark. His body started glowing, absorbing all the natural energy for the future. He breathed a sigh, "this is a whole new body. It's...so weak..."

"No, this is much better," Tsunade made him look towards her. There was a blanket under them while they were lying on the floor. He inched closer to her, pulling her closer, planting a grateful kiss to her lips, "Thank you.

Tsunade ran her fingers through his hair, stroking the back of his neck. She stroked his face, "Before. All I could see you was through the haze of aura. Now that I see you...you are slight handsome."

"That's new. All I ever heard in this life was that I looked sickly," he chuckled.

"That too. You think if your aura wasn't constantly visible it would be so easy for me to recognise who you are?" Tsunade raised her brow.

"Good point."

"On that note," Tsunade touched his chest, "why did your body change?"

"Oh, that's the secondary property of Abyssal Aura. It devours everything and makes them a part of it," Enma raised his body on his elbow, "Usually it takes 2 weeks. I didn't realise Communication could help me shorten down to 1 Hour. Although..for that...I have to give myself away."

"I see," she circled her arms around his body, "what do you plan to do now?"

"I need to complete something, and there is something you need to know," he pulled her on top of him, grabbing her ass.

"What?" she whispered.

"I gained Rank 3 Senju Physique," he went on to explain how his Byakugan reached Rank 4, and Sharingan reached Rank 5 and the powers that came along with those, and how he could help other's reach a Higher Rank Sharingan, Byakugan, and even...

"Physique," Tsunade muttered, straddling him, "what do you need to upgrade it?"

"Three more times should do," Enma thought, "another time to pass it on to you."

Tsunade curled up over him, grabbing him by his face, kissing his lips, "Then we should start..."

"Sure but..." Enma pointed towards the door, "Who is that?"

Tsunade followed his eyes, looking at the brown-haired, green eyed young woman watching them with sparkling eyes. She felt a sweat roll down her face, "Aerith?"

The woman took that as an invitation to come in, "it's true," she marvelled at the sight of Enma. She ran and knelt down beside him, poking his cheek, "I heard from His Majesty that a him from Parallel World was stranded in this world. It's so true!"

"Aerith," Tsunade didn't know what to say to stop her.

"Come on, don't hog him," Aerith gave Tsunade a pleading look with her big brown eyes.

"This is not a game," Tsunade sighed, tucking her hair back, "I am helping him."

"Right, right, so am I," Aerith stroked Enma's hair, who closed his eyes. There was such warmth in her fingers that he almost lost himself, "he has so many energies inside of him. The Cetra factor would allow him to organise and control them. See, I am needed here or His Majesty wouldn't have told me the secret," she proudly puffed her breasts, proudly raising her chin.

Enma raised his body on his elbows, "So, what is happening?"

"It's your treat, enjoy."

King Aurum was walking on the streets of Senju Village, looking at the people passing him by. Many of them looked like villagers, some were covered in mud or soot, while others few wore luxurious clothes. He stopped at a shop for clothes, looking at the prices, 'look affordable.'

He walked away with a smile, 'at times, waiting is all you can do.'

"Giving him power? That's a brilliant move. All you did was add gasoline to fire."

Aurum glanced towards Augustus, who walked beside him, "Why do you always nag?"

"Why do you never care to share your plan, especially when they involve world ending scenarios?" Augustus retorted.

"It will be fine. I am going to be a father, and I have a new son. Which reminds me. I haven't seen Arthur since I came here. What did Eve say?"

"He's having hard time growing stronger, and he knew this would happen. He doesn't want to ask for your help," Augustus shrugged.

"That kid is too honest," Aurum chuckled, "I'll go see him."

"Don't you need to start the preparation for marriage?"

"Oh yeah. I'll do that after I see Arthur," Aurum waved his hand, disappearing in the crowd.

"Why don't I believe you," Augustus narrowed his eyes, exhaling, "Damn it. What is he planning now?"
