Reincarnated as a Dungeon Master, I Became Unstoppable by Doting on My Monsters—My Gorgeous Monsters Have Started to Conquer the World on Their Own!

I was lying face-down on the bed with nothing but my underwear on. I was dressed like I was receiving a beauty salon, but the sound of comfortable metal clashing against metal echoed through the room, not the sound of oil.

“… It’s over. Are you okay? Does it hurt anywhere?”

A husky voice. But the affectionate kindness that dwells within it is delicate once you get used to it.

It was the voice of Lidvina Verney, one of Nanaya’s shrine maidens

“Yeah. Mr. Jacqueline’s anesthetics are perfect as always.”

I put my hand on the gooper to check. I put strength into it, but I don’t feel it. It’s a strange sensation.

“…Yeah. I don’t think alcohol alone is enough to make an anesthetic.”

She muttered to herself as she placed the heated chisel alone on a silver tray.

“Mr. Jacqueline’s anesthetics are amazing, but… Lidovina did a good job, too. Thanks for being off duty.”

Lidvina… As a D-Rank monster of the devil race, she’s the best at cursing and magic in our Dungeon.

I’d had tattoos carved all over my body in anticipation of her talent.

…That said, the magic circle was the one she had carved for me. Lidvina had been treating me nonstop for a while now, so it was only on the fourth day that I finally finished cutting.

“Geez. I’m more grateful that you called me outside of work.”

Lidvina smiled somewhat sluggishly. In response, I raised my cheeks, unable to move properly due to the anesthesia, and smiled.

After finishing the procedure, she sat in her chair, exhausted, and even had that expression.

…Lidvina seems like a popular artist from a club overseas.

The room where this tattoo was carved was also Lidovina’s private room. Still, it was filled with an atmosphere like a famous shop with a fixation on miscellaneous but uniformity, a noisy but calming view.

Her outfit was advanced, even by Earth standards in her past life. First of all, her top was wearing a black off-shoulder bische inside a rough black mesh shirt.

Furthermore, she was wearing a tight purple oversized nylon jacket on top of it, and on her legs, which peeked out from her shorts, was a tattoo carved by her magic, seeping through her tights.

She also had pink hair and thick lipstick mixed with a bit of purplishness. She had an extraordinary figure, maybe 175 centimeters long, and a well-defined face that was young but already complete. She had a melancholic expression that gave off a hint of decadent eroticism.

This woman, who could be used as a CD jacket no matter where you cut her, was Lidovina Verney.

Due to certain circumstances, she considered being in this Dungeon the only “duty” among Nanaya’s shrine maidens, so she wore a maid outfit during the day and maintained this street fashion style at night.

“That’s right… Could you bring me a mirror?”

I wanted to see the tattoo she had put on me, so I sat up, but she stopped me.

“Ah, wait. The anesthetic might still be working, so don’t stand up. You might collapse, so sit down for the rest of the day.”

“Huh? Like this for a whole day? Can’t I move?”

“That’s why there are so many girls.”

“… That’s not what I meant.”

When I calmed down and retorted, Lidvina laughed with a “fufu.”

“Here. This is a mirror.”

Lidvina brought me a dull square mirror. …No, maybe this is more stylish. She’s got better taste than me, so I honestly don’t even know if she’s fashionable.

…It seems unheard of, but we use contract magic to give everyone permission to use Dungeon Cores. That’s why I haven’t checked every single one of the girls’ belongings.

That’s more efficient when living together, but why don’t other dungeons do that?

“Yeah. You are good.”

I checked my body, which didn’t seem to belong to me, with delicate ancient Etina script engraved on it.

Still, I didn’t think I’d get a lot of tattoos as a result of going to another world myself.

…Of course, I didn’t put it in fashion.

During my previous encounter with the Goddess Nanaya, my heart and soul. All of them have been branched out.

…I have a lot of regrets and worries, but I’m glad things didn’t get that bad. Indeed, the ‘love’ I’ve been chasing for so long has been taken away, but it was something I’ve half given up on in the first place.

In the worst-case scenario, it wouldn’t have been strange if all of us had been robbed of consciousness and turned into machines that slaughtered humanity, so if the role of Dungeon Master were to send people who were already dead to heaven, it would probably still be better than nothing.

You could say it was a job worth doing if you considered it to maintain the balance of the world.

…But I can’t let Nanaya’s shrine maidens get involved in my deal.

I’m carving an emergency magic circle all over my body to avoid the worst-case scenario, where my contract with the girls would be stolen when Charming Magic ruled me myself.

There’s also a curse mixed in with this carving so that even if I die and it pops, it won’t be lost.

Lidvina had done some serious research and completed a magic circle that could maintain the curse so that I wouldn’t be burdened.

“Does it look good on me?”

I was excited about her masterpiece, and I wanted to tell her that I was happy when I worked hard to research it, so I asked her that.

“Yeah. It’s cool. I’ll show you my back, so turn around.”

She held a mirror behind her like a hairdresser.

Since it was made up of only practical magic circles, not decorations, the hilt itself didn’t show her sense of style. However, I thought it would be better than what I’d do in a place like this, where I’d have to deploy the necessary magic circles.

Right now, my body must be in a state where some magic manifests no matter where I gather my magical energy.

Besides, there was a certain patterned painting carved into her back that I’d asked her to design.

“Wow, you’re good. I knew you’d do it.”

“You said you were good at it. Didn’t I show you the draft earlier?”

“Still, when the color comes in, it’s on a whole different level.”

There are two playful dogs carved into my back. They’re space dogs that were used for Soviet experiments and never come back to Earth. Barusu and Rishichika have Japanese-style tattoos.

I don’t plan on going back to Earth anymore… Well, I’m dead, and I’ve been here for ten years, so it’s only natural, but… I had her express her resolve. But I don’t want to forget Earth even after hundreds of years, and I put those two determinations into one picture simultaneously.

That said, she hadn’t carved it entirely out of a hobby but to hide another magic circle drawn beneath it. Since there was a magic circle cut into her back for combat magic, she needed to hide the hilt by overwriting it so the enemy wouldn’t notice her handiwork.

…Yeah. But I do like this pattern. I like dogs.

“I’m glad that Lidovina, who can carve tattoos, is among Nanaya’s shrine maidens, who can trust her back with peace of mind.”

“It’s fine. Honestly… I was relieved to have my proof carved into the wight outside work hours.”

Lidvina’s lips twisted in mockery as if she thought her statement was pathetic.

…The reason she emphasizes being here as a “duty” is because she’s a demon.

Ten years ago, I hadn’t given it much serious thought, but in the first place, it seemed that in the initial contract stage, the angels and devilfolk were in the form of “being lent to me.”

First, the premise was that angels were servants of the gods, and demons were servants of the gods, so they were born as property of such gods. That was clearly stated when summoning them.

That doesn’t mean she’ll suddenly be taken from her, but she doesn’t seem to like her position as an errand boy for her god.

By diligently acting as a maid during the day, she insists that “I was loaned to an Archdemon as a demon at this time of day,” she distinguishes herself from the rest of the evening street fashion as her “real self.”

By doing so, she seemed to assert she was here of her own free will. The reason she preferred hip hop with a free soul was probably because of her origins around here.

“Yeah. I won’t erase this tattoo as long as I live. I promise. Never.”

Maybe that’s why she wants to leave proof that she can’t disappear so that she can leave at any time. …It seems that Lidvina’s inner thighs have several layers of ‘wit’ tattoos so that no matter what happens, they won’t disappear from her body.

“… It’s fine. More importantly, everyone’s worried about you in front of the door. Let me in.”

“Yeah, do that.”

When Lidvina opened the door, ten people other than Rosa Rosa and Biondetta, engaged in long-term covert missions, entered the room briskly.

Then, she saw me covered in ink and knelt, her face pale.

“I-I’m so sorry! We’re worthless, and Master’s noble body is irreparable…”

When Margarita said that, everyone continued apologizing, saying, “My apologies!”

The girls bowed their heads so low they felt like they were going to scrape against the ground, but rather than kneeling, they seemed to be being held down from above by a strong gravity.

“Okay. Everyone, raise your heads first.”

I’ve been with them since they could talk, and I know they’re lifting me.

I’ve been teaching for ten years, so maybe I’ve become a teacher she admires. But that doesn’t mean it’s hard for her to worry about me every time something happens.

“There’s no need to apologize. Here, take a look at this tattoo. Isn’t it cool?”

When I said that, the girls raised their heads as ordered and took a good look at my body. The most effective thing for these depressed girls was that I was having fun.

For the sake of those girls whose minds are a little unstable, I can’t let myself get depressed.

Even so, it would be embarrassing to have ten people staring at me in nothing but my underwear…

However, the girls continued to look at me seriously, clasped their hands together as if in prayer, and nodded repeatedly with enraptured faces.

“Yes…! Yes…! Very! It suits you very well!”

It was a “yes” filled with a feeling of omnipotence. The girls looked up at me, their bodies melting as they fell forward on their knees and their eyes watered.

Looking at the expressions on the girls’ faces, I can tell they think I’m cool.

That’s Lidvina’s tattoo for you.

“Whoops.”

When I twisted my body to show the puppies on my back, I couldn’t put enough strength into my body because of the anesthesia, and I felt like I was going to collapse.

“Sir!”

I lost my balance and was supported by her soft body. It was Margarita who wrapped her arms around me.

And immediately after that, everyone lifted me to support me.

…Am I a portable shrine?!

“… I’ll be caring for you all today, Master.”

Margarita sounded like she was scolding me. She must have known I was about to turn down that request.

“Everyone’s fine. Rosa Rosa and Biondetta are doing their best, so I have to do my best, too.”

“No, it’s dangerous today. …After all, they’re working for you in the first place. I’m sure they’d be happier if you said, ‘They’re working for me, so I’ll take my time.’”

Margarita said it was quiet. What she was saying was gentle and respectable, but…

“Um, Margarita? It kind of tickles.”

Her hand, which was supporting my butt, had been moving casually for a while now.

“Huh?! Ah, m-my apologies! Um… There are still too many signs of human bodies giving off when they lust, so I can’t control them… I should have been able to suppress their reactions for quite some time…! I’m sorry for showing you such an unsightly side of me.”

Margarita turned pale and bowed her head. Even I felt bad for making such an exaggerated apology.

“It’s fine. Everyone was somewhere else right after they became human. A lot is happening while you’re not used to it.”

“Y-Yes. If everyone makes eye contact with the Master and gets wet or opens their legs on their own, I won’t be able to fulfill my duty as his subordinate to the fullest…”

Margarita deftly and sadly looked down as her cheeks flushed. It seemed the human body wasn’t all good, either.

“…First of all, Margarita and everyone else aren’t my subordinates. They’re important to me… And I’m worried about Rosa and Biondetta being sent outside that state.”

I recalled how I’d followed up with Margarita, who tended to be hesitant and sent them off immediately after becoming human. What was she doing right now? I wished she’d made friends outside.

“Th-Thank you very much. I-It’s those two, but as long as they’re outside, there shouldn’t be a problem! They’re only symptoms within the Dungeon.”

Margarita said to mend it. By “only within the Dungeon,”… was it the hidden curse of the Goddess Nanaya?

In any case, it didn’t look like any of the ten of them would make a move while holding me, so I had no choice but to do what I could here.

That said, my only job after returning from the temple was to receive reports and make final decisions, advise the shrine maidens, and read books.

“…Well then, I’ll have everyone care for me for the rest of the day. However, please prepare for the invasion plan to begin. There’s no need to add my return period to the plan.”

But even I, who have nothing better to do, must prepare for a certain plan I need to do in the future.

“…Certainly. There’s nothing to worry about.”

Margarita nodded at my words, but it seemed she wasn’t convinced. But, of course, she was still suffering from the aftereffects of the anesthesia, so I wanted to have a conversation with her at least…

As I smiled wryly at Margarita’s worrywart nature, I suddenly heard a voice as clear as an army from one of the shrine maidens supporting my legs—the voice of the amorphous monster, Clarymond Ziebencase.

“In that case, the route to Planned Ground C has already been decided. I hope you will organize several people by tomorrow, including Miss Egrentine, except the Dungeon Defense Force.”

Margarita grimaced indignantly as if indignant at my sudden outburst about the battle. But please forgive her. Clarymond has a role to play.

She wore a green bow in a military uniform, and concrete strategy was also her specialty.

Planned Ground C… It’s the temporary name of the island we decided to electrify in just one day. Of course, the enemy isn’t human. It’s a dungeon.

“Yeah. Clarymond. If you don’t know what they’re capable of, you can throw in as many as you want. I’ll leave the organization to you.”

I decided to throw everything I had at her. She would probably do much better than I did now.

The girl did not attempt to hide her ferocious smile as she said, “Understood,” raised one hand in front of her forehead and made a gesture of understanding.
