Becoming Demon Lords?

Tatsuya Pov-

I got up from the bed as I looked at the peacefully sleeping Mikasa. The thought of waking her up crossed my mind for a moment before remembering the barrage of fireballs that attacked me the last time I woke her up.

Exciting the room, I noticed something weird.

"Why is the floor wet?" I thought, looking at the water splashed near the end of the door. Shrugging, I went downstairs.

Entering the kitchen, I noticed that Tsunade was sitting at the dining table while eating her breakfast. She was wearing her signature sleeveless kimono-style blouse with an obi keeping it together, emphasizing her breasts while showing a deep valley that anyone would want to explore. She was also wearing a necklace that was stuck inside the said valley.

Getting a grip, I moved my eyes above, looking at Tsunade's face. She noticed me looking at her bust but she wasn't uncomfortable with it. Did she look... proud?

"Good morning." She greeted me with a smile on her face, pointing a finger toward the chair next to her. "Have a seat, I'll serve you."

'Lady, your inner horny is too much, it's almost leaking out. Wait, leaking out. That's it.' I almost choked on air when I realised why the floor outside our room was wet. 'You could've joined us. Mikasa would've loved it.' I thought.

I used my Natural Energy Perception to check whether my 'theory' was true or not and guess what? There's a damn hole near the door, exactly four feet above the pool of water.

I took a seat next to Tsunade, who was looking at me before she got up and started serving me food. After that, she sat back on the chair.

"It's good." I said. Tsunade rarely cooked ever since she moved in, so I never knew that she was this good at cooking. Although not at Hikari's level, it was quite good.

"I've been learning about cooking from Hikari." Tsunade said with a smile.

"I see." I replied. 'Maybe they get along because their sizes are almost the same?' That was my honest opinion. In the whole Naruto world, only Hikari rivalled Tsunade when it comes to curves and sizes. Maybe Samui would in the future?

"Oh right. Tsunade-sensei, we'll be leaving for a while." I decided to drop the bomb as Tsunade's fork stopped mid-air, she looked at me with a frown. At least act like you're 32.

"Where are you going?"

"Another world."

She hit the table with her left hand, spilling some broccoli from her plate. "Don't joke around. I'm being serious."

'I was being serious.' I wanted to roll my eyes but didn't in fear of her clinging to me.

"We're going to meet a friend." A 20,000-year-old Demon Lord who's also the True Ancestor of all Vampires. Did I mention that she can also revive the dead? Yes, an old friend everyone would love to meet.

"Who is it?" Tsunade asked, narrowing her eyes.

"You don't know her." I purposefully mentioned the word 'her' to mess with Tsunade, but her reaction was kinda unexpected.

She smiled at me before leaning forward and asking, "So it's a girl?"

'I wonder if Luminous would be a girl or a lady?' I thought while nodding.

Tsunade didn't ask further, just saying, "Be careful." But there was a smile on her face that reminded me of someone. And honestly, it was scary.

Her smile was the same as Yuno Gasai from future dairy. 'Maybe she'll kidnap me?' I thought, wondering. Tsunade left with the same smile, leaving me alone.

Bored, I decided to contact Pakura.

{Hey, what are you up to?} I asked.

{Hunting some bandits. These guys are like cockroaches, they just won't die.} I could hear the annoyance in her tone when she said that. Yeah, the cute girl I once saved has turned into a bandit hunter. I internally sulked.

{Anyway, why are hunting bandits?}

{It's a war? Maybe that's why? These guys have been stealing loot from the dead ninjas for a few months so I decided to come here and relieve some stress.}

What kind of stress are you releasing while killing bandits? Mikasa was nothing but a bad influence on Pakura.

{Forget about that. We're leaving for a few months.}

{Is that so? I'll be keeping Ellie in the meantime.} At this point, Pakura was immune to us disappearing out of nowhere.

{That was close. His blood almost ruined my clothes. Tch.} I can hear you just in case you forgot.

{Take care of Hikari while you're at it. If she doesn't listen to you, just spank her once.} I gave Pakura the ultimate solution to make Hikari obey.

{Okay. Don't do anything dangerous while you guys are away, and look after Mikasa.}

{Yea, mom.} I said before cutting the telepathic link.

We had already created Teleportation Seals that connected our house, Pakura's house and Hikari's house so that it'll be easier for the others to come and go without us.

The only thing they require is the pass that'll allow them to teleport through them. Pakura tried learning the Flying Thunder God, but her aptitude was... terrible at best. Well, I planned on drilling it into her body once I had some free time. Literally. My thoughts came to a halt as I noticed a golden hologram appear in front of me.

[The Divine Prophet is online]

[The Queen of Nightmares is online]

[The Last Judgement is Online]

"So she's up?" I muttered.

[The Queen of Nightmares- When are you guys coming?]

[The Divine Prophet- We'll be there in a few minutes, I am getting dressed.]

[The Last Judgement(Admin)- You want some breakfast?]

[The Divine Prophet- No. I am full thanks to you feeding me last night. Even my butt is sore now.]

[The Last Judgement(Admin)- Can't you heal it with Medical Ninjutsu?]

[The Divine Prophet- Don't wanna.]

[The Queen of Nightmares-...]

[The Last Judgement(Admin)-...]

3rd Person Pov-

Luminous was sitting on her throne that was placed high above the ground, looking at the chat group in front of her.

Down below, a tall man with blonde hair was standing while looking at the floor, his expression was respectful. He looked similar to Louis but was his twin brother, Roy Valentine, the one posing as the Demon Lord Valentine. He was wearing white clergy robes, similar to his brother so that no one inside the Empire would realize that he was actually a Demon Lord. Unlike his brother, his personality wasn't as calm and collected. On the other hand, he was quite aggressive and acted without actually realizing the situation.

Roy, who was looking at the floor suddenly heard a voice full of curiosity and eagerness. "So this is your home? As expected of a Demon Lord." The voice belonged to a girl in her teens.

Roy looked up in a hurry, only to find his master was being poked in her cheeks by the fingers of two humans. One male and another female. Their eyes were full of curiosity as they looked at Luminous, who had veins popping out of her forehead.

'Intruders.' That was his only thought before he moved to attack them. The one he first planned on attacking was the girl. Although he couldn't sense any malice from the two of them, touching his master's cheek in such a disrespectful way is a slap to the whole Vampire Race. If he knew about how they actually planned on touching her, Roy would've fainted from humiliation and shame.

Luminous noticed this but didn't interfere, she was quite curious about how strong Mikasa and Tatsuya actually were. She wasn't able to sense any Magicules from them, indicating that they don't have any 'Skills' or Magic.

Roy, who was already in a position where he was ready to punch Mikasa noticed that her eyes started to change as she activated her Mangekyo Sharingan.

'Mienai Sekai' She activated her best defensive ability as her body disappeared. Roy's punch hit nothing but air, creating a strong gust of wind, surprising both Roy and Luminous. But the latter was surprised for a different reason.

Mikasa knew that there was no way she'd be able to beat Roy without exposing most of her cards, and even then, her victory wasn't guaranteed. Not to mention that Roy and his brother, Louis, were actually one being. If they combined again, Mikasa and Tatsuya wouldn't have that much of a chance against them. Mikasa was now wondering how powerful Luminous was, being able to split someone like that into two.

Thinking about it now, this universe was indeed unreasonably overpowered. Well, considering that the other party was a True Demon Lord Seed, it's more or less understandable.

"That's enough, Roy. These are the guests I was talking about yesterday." Luminous said while raising her hand a bit. She placed her hand near the spot where Mikasa was standing before flicking her finger.

Along with a Thud* sound, a girl's cry of pain could be heard as well. "That hurts." Mikasa grumbled before realising something. "How the hell are you able to touch me?" Even if invisible, the shock in her voice couldn't be hidden. Tatsuya also had a shocked expression while looking at the beautiful girl sitting on the throne with a charming smile on her face.

"You're in the realm between this world and the world of spirits, right? Anyone strong enough would be able to hit you like this, much less see you."

Mikasa, who had little idea about what Luminous was talking about deactivated her ability. Tatsuya, on the other hand, was already looking at this world's 'Power Card'. It was a Chat Room privilege that'll 'upgrade' the user's body so that it'll be able to handle powers from multiple worlds.

[Tensei Slime Power Card- 5,000,000 System Points]

[Admin's Privilege- 30% Discount Apllied]

[Tensei Slime Power Card- 3,500,000]

'Unreasonable.' That was the only thought on his mind as he looked at the price. A red hologram appeared in front of him, covering the golden one that was already there. It was a message from the system that the NEET ROB gave them.

[The price isn't unreasonable at all, host. This just represents how powerful the verse actually is along with the potential it offers]

'I guess. But why couldn't we get skills and Magicules like people do when they're summoned from Rimuru's original world?'

[The reason is simple. The original world of the slime named Rimuru was also created by Veldanava and is under the 'System' that he created]

'So that's how it is.'

"I apologize for the disrespectful greeting." Roy said, bowing his head. He wasn't an idiot. He understood the situation and decided to do what was appropriate.

"Don't worry about it." Mikasa said as she disappeared. Genuinely surprising Luminous and Roy. She appeared next to Roy before placing her hand on his back.

"You may leave." Luminous said before Roy nodded and turned around. Luminous and Roy failed to notice the paper tag that Mikasa left on his back. The former was simply focused on Tatsuya and Mikasa while the latter was thinking of ways to survive if his master was angered by him. After a few minutes, the hall vibrated a little.

"Did you guys feel something?" Luminous asked, confused.

"No."

"It's your imagination." Tatsuya and Mikasa both denied it without any delay. Knowing that Roy was probably slammed into some random wall from the explosion. They doubted that the tag was strong enough to damage him, but this was fun as well.

"So, tell us about your world." Tatsuya asked.

Luminous started explaining about her world. From the Ten Great Demon Lords to Roy being one of them. She carefully avoided anything that might give them hints that she knew the future, or at least part of it. She was considering whether to ask Mikasa about her future or not.

'So Rimuru has yet to become a demon lord? I wonder if the plot has started already.' Tatsuya thought. Since Roy was still alive, that was a clear indication that the Octagram has yet to be named by the Ultimate Naming Slime.

Tatsuya and Mikasa noted that she was clearly emphasizing the word 'Evil Lizard' throughout her explanation whenever she talked about Veldora.

They were planning on making their way toward the Great Jura Forest after playing around in Luminous's Empire for a few days.

"Maybe we should become Demon Lords as well?" Mikasa muttered with a smile.

A/N-

I know the chapter is way too short. Considering that the average word count is above 2.7k

Sorry about that.

Random Numbers Recommendation-389238(Warning: You'll never be the same again after reading this.)

Author Asks For Help- I want to give Junko some superpowers on the first mission so that she can... you know, donate despair to different worlds. I was wondering if Black Clover was a good option. Maybe she'll get some Despair Magic? Idk. Is there any other verse that has something like the grimoire ceremony in Black Clover?

Additional Note- No clone s*x. That's never gonna happen. Someone's comment got deleted by we novel so I decided to add this here.
