My Dungeon Daddy System: Raising Monsters and Waifus Underground

The dungeon was vibrating, and not in the good way.

It was the specific, headache-inducing vibration of too many personalities crammed into too little square footage, all of them loud, messy, and physically overwhelming.

Reed sat on the edge of his stone bed in the Core Chamber, head in his hands, trying to filter out the noise echoing from the corridor.

From the workshop cavern came the clang-clang-cuss of Grika hammering something that definitely didn't want to be hammered. Mixed in with the metalwork was the distinct, wet shlorp of Luma moving around. The slime girl had discovered that if she moved fast enough, she made a sound like stirring mayonnaise, and she had been "practicing" her stealth movement for an hour. It wasn't stealthy. It sounded like someone walking in wet galoshes filled with pudding.

And from the newly carved Knight's Gallery, there was the rhythmic thud-hiss of Seraphine running combat drills. Every time she cornered a turn, her massive tail slapped the stone with enough force to shake dust from the ceiling.

"I died and went to heaven," Reed muttered to the glowing crystal behind him. "But heaven is a frat house for monster girls and I'm the RA."

He stood up and walked to the doorway, peering into the gloom.

The state of the dungeon was… lived-in. And by "lived-in," he meant it was a disaster zone of fluids, scrap metal, and scales.

Patches of the floor were slick with a glittering, blueish residue where Luma had decided to "nap" on the cold stone. Scraps of jagged iron and twisted wire littered the corners where Grika had tossed them. And there were long, scuff-mark grooves in the walls where Seraphine's armor had scraped during her enthusiastic patrols.

Reed rubbed his eyes. He was tired. Not just physical fatigue, though his body still ached from Grika's "thigh-clamping" lessons yesterday. It was a mental exhaustion—the kind that came from trying to manage a team that didn't know the meaning of personal space or boundaries.

The System, sensing his crumbling morale, pinged softly.

[LOGISTICS ALERT]

Sanitation Level: Sub-optimal (Sticky).

Organization: Chaotic.

Master Stress: High.

Analysis: You require a handler.

Recommendation: Summon Logistics Support immediately.

Reed stared at the blue box. "A handler. Yeah. That sounds about right."

He pulled up the Summoning tab. He had enough Mana now—the adventurers' repeated visits and the constant background generation from his "happy" monsters had pushed him back over the 15 DM mark.

He scrolled past the combat options until he found the one the System was practically screaming at him to pick.

[Demon Maid Template – Maira]

Cost: 12 DM

Role: Logistics / Security / Domestic Management

Traits: Strict, Efficient, "Crisis Protocol"

Description: Order is not requested. It is enforced.

"Maid," Reed said, testing the word. It conjured images of dusting and tea. Safe images. "Okay. Someone to sweep the floors and maybe tell Grika to stop leaving tripwires in the bathroom."

He selected the template.

[CONFIRM SUMMON: Maira]

Cost: 12 DM

Proceed? Y/N

He took a deep breath, inhaling the scent of ozone and goblin sweat that currently permeated his home.

"Proceed."

The reaction was immediate.

Usually, summoning felt wild. Grika's had been a spark-shower; Luma's a splash; Seraphine's a heavy, noble pressure.

This was different.

The mana didn't surge; it obeyed.

The air in the Core Chamber dropped ten degrees instantly. The humidity from Luma's presence vanished, replaced by a bone-dry, crisp chill.

A summoning circle etched itself into the stone floor, but it didn't glow with wild, fluctuating light. It burned with a steady, deep crimson radiance, the lines perfectly geometric, sharp as razor wire. There was no sound, no thunder, no chime. Just a heavy, suffocating silence that swallowed the noise from the other rooms.

In the center of the crimson light, a silhouette rose from the floor like ink bleeding upward.

It started with heels, sharp, dangerous stilettos that clicked against the stone before they even fully materialized. Then long, shapely legs sheathed in black silk. The curve of wide hips, the cinch of a impossibly tight waist, and the swell of a bodice that looked like it was holding back a tidal wave.

The light snapped out.

Reed blinked.

Standing before him was a woman who looked like she had walked out of a librarian's fever dream.

She was tall, easily matching his height even without the heels. Her skin was pale as milk, flawless and smooth. Jet-black hair was pulled back into a bun so severe it probably hurt, though a few stray strands framed a face defined by high cheekbones and narrow, amber eyes behind rimless glasses.

She wore a maid's uniform, but it was to a standard maid outfit what a tank was to a tricycle. The black fabric hugged her curves with aggressive precision. The white apron was pristine, tied with a bow at the back that drew the eye to the sway of a long, thin tail ending in a sharp black spade.

Small, curved horns poked from her temples, glossy and sharp.

She didn't move. She didn't breathe. She just… stood there.

Reed cleared his throat. "Um. Hi. I'm Reed. I'm the—"

Maira moved.

She didn't walk; she glided. The click-click-click of her heels was a metronome of doom as she closed the distance between them.

She stopped six inches from him. The scent hit him then—not sweat or oil, but starch, pressed linen, and a deep, heady undertone of spiced wine and old paper.

She adjusted her glasses with a gloved finger. The lenses flashed opaque white.

"Master," she said. Her voice was low, smooth, and utterly devoid of warmth. It sent a shiver straight down Reed's spine. "You are slouching."

Reed straightened up instinctively. "I—what?"

"Shoulders back," she commanded. She reached out. Reed flinched, expecting a strike, but she simply laid her hands on his shoulders. Her grip was firm—shockingly strong—and she physically wrenched him into a better posture.

"Chin up."

She moved a hand to his chin, tipping his head back. Her leather glove was cool against his skin. She leaned in, her face inches from his, inspecting him like he was a piece of produce that might be bruising.

"Pupils dilated," she murmured, her amber eyes scanning his. "Skin flushed. Pulse… elevated."

She dropped her gaze to his chest. She brushed a speck of dust off his tunic with a flick of her finger that felt like a whip crack.

"You look disheveled, Master. Like a stray dog that has been rolling in the mud."

"I've been busy!" Reed protested, his voice cracking slightly. "Building. Managing. Surviving."

"Excuses are the refuse of the inefficient," Maira stated. She stepped back, smoothing her apron. Her tail lashed behind her, the spade tip carving a shallow scratch in the stone floor. "I was summoned to bring order. I see I have my work cut out for me."

She turned on her heel, surveying the Core Chamber.

"Dust," she noted, pointing at a corner. "Grit." She pointed at the floor. "And…"

She paused, looking at the door to the workshop.

"Noise."

"Hey!" Grika's voice boomed as the goblin strolled in, spinning her wrench. "Who turned down the thermostat? It's freezing in here."

Grika stopped when she saw Maira. The goblin blinked, looking the new arrival up and down.

"Well," Grika smirked, leaning against the doorframe and crossing her arms, which pushed her already-strained tank top to its limit. "Look at this. Since when do we have a dress code? You look like you're about to serve tea or spank someone."

Maira turned slowly. Her expression didn't change, but the temperature in the room seemed to drop another five degrees.

She walked toward Grika. Click. Click. Click.

"Goblin Unit Grika," Maira said. "Engineering."

"That's me," Grika grinned, showing teeth. "And who are you? The fun police?"

Maira stopped in front of the goblin. Grika was short, muscular, and radiated chaotic energy. Maira was tall, poised, and radiated absolute control.

"I am Maira," the demon said. "And you are in violation of fourteen separate safety and hygiene protocols."

Maira's eyes dropped to Grika's shorts—denim cutoffs that were more 'cut' than 'off,' practically disintegrating at the seams.

"Your attire is insufficient," Maira noted.

"It's practical," Grika countered, popping a hip. "I work in a hot forge. I need ventilation."

"You need decency," Maira corrected. She reached out and, faster than Grika could react, plucked the wrench from the goblin's hand.

"Hey!" Grika yelped.

Maira inspected the wrench. "Grease," she said, wrinkling her nose. "Rust." She wiped it on a cloth that appeared from nowhere in her apron, then handed it back. "If you cannot maintain your tools, how can you maintain this dungeon?"

Grika snatched the wrench back, her ears flushing green. "I keep my tools fine! It's called usage marks!"

"It's called neglect," Maira said smoothly. "You will report to me later for… measurements. We will find you a uniform that supports your function without exposing your… lack of discipline."

Grika opened her mouth to argue, but Maira had already moved on.

Luma had picked that moment to peek out of the safe room. She saw the tall, scary lady in black and white, squeaked, and tried to pull back.

"Slime Unit," Maira called out. The voice wasn't loud, but it carried a weight that made Luma freeze.

Maira glided over to the safe room entrance. Luma was currently in her semi-liquid state, half-draped over her stone bench like a forgotten towel.

"You are… dripping," Maira observed, looking at the blue puddle forming under the bench.

"I-I'm sorry!" Luma stammered, trying to pull herself together. "I'm mostly water! And magic! It just… happens!"

"Liquid requires containment," Maira stated.

She reached into her apron pocket—which seemed to operate on cartoon physics—and pulled out a yellow measuring tape.

"Stand up," Maira ordered.

Luma wobbled upright. Her "dress"—a mimicry of fabric made of her own slime—shifted and swirled.

Maira stepped into Luma's personal space. She didn't hesitate. She wrapped the measuring tape around Luma's waist.

"Viscosity… high," Maira murmured. "Surface tension… poor."

She pulled the tape tight.

Squish.

"Eep!" Luma let out a high-pitched sound as the tape cinched her waist. Because she was a slime, her mass had to go somewhere. Her hips flared out abruptly, and her chest swelled upward, straining against the translucent "fabric" of her form.

Maira ignored the sound and tightened it another inch.

Squelch.

"Oh!" Luma gasped, her face turning a vivid, glowing teal. She looked down at herself, watching her own body distort under the pressure. "That's… tight! M-Maira, it's squeezing me!"

"Structure is important," Maira lectured, her face inches from Luma's heaving chest. "Without containment, you are just a mess. With discipline, you are a tool."

She released the tape, and Luma's body snapped back into shape with a wet wobble that reverberated through the room.

Luma stood there, panting, looking confusingly flushed. "I… that was… intense."

"We will work on your surface tension," Maira said, making a note on a small pad. "You leave residue on the Master's furniture. It is unacceptable to be so… leaky."

Luma covered her face with her hands. "I'm not leaky! I'm moist!"

"Disgusting," Maira noted, turning away.

Seraphine had slithered in from the gallery, drawn by the commotion. The massive lamia knight coiled herself in the center of the room, her armored upper body rising to look Maira in the eye.

"A new arrival," Seraphine said, her voice cool and imperious. She looked Maira up and down. "A servant? Appropriate. The Master requires someone to tend to the menial tasks while we focus on battle."

Maira looked up at the lamia. She adjusted her glasses.

"Guardian Unit Seraphine," Maira said. "I have inspected your gallery."

Seraphine puffed out her chest, armor glinting. "It is a glorious arena."

"It is a scratching post," Maira corrected. "There are scale marks on the pillars. And you shed."

Seraphine blinked. Her tail twitched. "I… molt. It is natural."

"It is untidy," Maira said. She pointed a gloved finger at Seraphine's massive, coiled tail. "And you take up too much floor space. You are a tripping hazard."

Seraphine's eyes narrowed into slits. "I am the Guardian of the Third Floor. I do not 'trip' people. I crush them."

"Then crush them neatly," Maira snapped. "And polish your armor. I can see your reflection, and it is smudge-ridden."

Seraphine looked down at her breastplate. There was, indeed, a smudge. She rubbed at it self-consciously.

Maira clapped her hands. The sound was sharp, like a gunshot in the enclosed space.

"Enough."

She walked back to the center of the room, standing next to Reed. She towered over him in her heels, her presence encompassing.

"This facility is operating at peak inefficiency," she announced. "That ends now."

A holographic window popped up in front of everyone. It was color-coded. It was detailed. It was terrifying.

[DAILY REGIMEN – MAIRA'S ORDERS]

0600: Wake Up.

0630: Hygiene Inspection (Mandatory. Failures will be scrubbed).

0700: Physical Conditioning (led by Seraphine).

1200: Engineering Review & Tool Cleaning (Grika).

1800: Core Maintenance / "Stress Relief."

Reed stared at the last item.

"Uh, Maira?" he asked, raising a hand. "What exactly is… 'Core Maintenance'?"

Maira turned to him. The look in her eyes changed. The cold, analytical glare softened into something heavier, darker. Her tail wound slowly around his leg, the spade tip tracing a line up his calf, resting just behind his knee.

"Running a dungeon is taxing, Master," she purred, her voice dropping to a husky whisper that bypassed his ears and went straight to his nervous system. "A tense Master makes mistakes. A… thoroughly relaxed Master… makes history."

She stepped closer. Her bodice brushed against his arm. She smelled of danger and spices.

"I am very good at removing tension," she whispered, her lips brushing the shell of his ear. "By any means necessary."

[MONSTER BOND – MAIRA]

Role: Logistics / Domination

Loyalty: 15 (Professional interest)

Trait: [Enforcement Seal] – Can physically restrict targets to ensure compliance.

Reed swallowed hard. His throat felt dry.

"Right," he squeaked. "Good. Schedule. I like schedules."

"Excellent." Maira pulled back, her demeanor instantly shifting back to cold professionalism as if the moment hadn't happened. She snapped her gloved fingers.

"Now. Everyone out."

Grika blinked. "Excuse me?"

"The Core Chamber requires deep cleaning," Maira stated. "And I do mean deep. There is slime residue, goblin grease, and scale dust on every surface."

She looked at Reed. A small, barely-there smile touched her lips.

"You may stay, Master."

Reed looked at the door. "But—"

"You are the dirtiest thing in here," Maira said. She reached into her apron and pulled out a feather duster. It shouldn't have looked threatening. It did.

"Grika, Luma, Seraphine—out. Now."

Grika looked at Reed, then at Maira, then back at Reed. She laughed, a low, throaty sound.

"Good luck, Boss," the goblin smirked, hoisting her wrench. "Don't let her bleach your soul. Or anything else."

Luma wobbled toward the door, casting a worried look back. "Bye Reed! Have fun getting… scrubbed!"

Seraphine just offered a solemn nod, as if saluting a soldier going to his execution, and slithered out, her tail dragging purposefully slowly across the floor.

The door clicked shut.

Silence descended on the Core Chamber.

Reed stood alone with the Demon Maid.

Maira walked over to the door and locked it. Click.

She turned back to him, slowly unbuttoning the cuffs of her sleeves. She rolled them up, revealing pale, slender wrists. She snapped a fresh pair of rubber gloves onto her hands. The sound echoed. Snap.

"Assume the position, Master," she said, walking toward him.

Reed backed up until he hit the Core. "Position? What position?"

"The cleaning position," she said. She pushed him gently but firmly until he sat on the edge of his bed. She stood between his legs, towering over him, duster in one hand, sponge in the other.

"We start with the ears," she murmured. "And then… we will see what else needs polishing."

Reed looked up at the ceiling, wondering if there was a prayer for dungeon avatars about to be aggressively organized.

This, he thought as Maira leaned in, blocking out the light, is going to be a very different kind of difficult.

He closed his eyes.

"Yes, ma'am," he whispered.

Maira smiled.

"Good boy."
