This story uses the same setting as my other story "Momon, Big Black Changeling". Essentially, Ainz Ooal Gown is the same type of creature as in that story, although this and that story happen in different worlds.

It had been some time since he had felt this way. When he had hunted down the "Wise King" he had felt a similar rush, but this new development was something else entirely. He could feel the tension ramping up in his nerves, and prickle his skin (which, for the moment, were human), and make excitement course through his whole being. In a way, it was like the build up of anticipation before sex.

"The patronage of the Red Moons has increased once again, Ainz-sama," Shalltear said over Message. "And the first adventurers we paid to spread the news have confirmed to have done so: both in the Baharuth Empire and the Re-Estize Kingdom."

"Ninya and Dee have also confirmed that piece of intelligence," Albedo said from beside him. "The Adventurer's Guild has also expressed concern about this and have planned to send a representative: should we do something about this, my lord?"

"Er…" Feeling overwhelmed by the constant reports, Ainz said, "Okay, Shalltear, keep up the good work, and I shall speak to you again for the next report. Thank you."

"Ah, Lord Ainz-!" He terminated the call, then turned to Albedo.

"Tell our group in Baharuth to stand by and continue with their current orders."

"Yes, my lord."

"Has Nazarick been prepared?" Albedo looked at him with surprise, before nodding doubtfully.

"Y-yes, as you ordered, Demiurge has reported that all essential personnel have been recalled from their outside duties in preparation for a large-scale assault. They are ready on your orders, Lord Ainz."

"Hum… Good," Ainz rumbled. He turned back to look outside the carriage.

He was finding it difficult to conceal his emotions, particularly from Albedo who was right there next to him. He found that his doppelganger body in this new world had visible ways of showing that he was gripped by a strong surge of emotion. His body would ripple in unnatural ways, like his skin was a disturbed surface of water. It didn't seem to affect his capabilities as a doppelganger, but he didn't want to risk the chance. He schooled his features, and spent the rest of the carriage ride thumbing through the many combinations of transformations that he had tested and accumulated all through his time here.

The news from Solution Epsilon and Sebas Tian about secretive creatures found lurking right beneath the estate given to the former raised a lot of Ainz's suspicions, at first. It smelled of some sort of trap, as if there was some sort of player behind it, testing Nazarick's readiness and power all without his knowing. It normally would have infuriated and frightened him, but he knew he could not just drop everything, retreat to Nazarick and bolt up the entrance. Not anymore.

He would need to test this new element in return. He would probe its depths, figure out its secrets, and determine its plausible threat to Nazarick. And if it really was a Player, then he would do anything and everything in his power to defeat it, for he now had a responsibility to Nazarick and to its denizens.

On the other hand, if it really was something tied to this new world, then that made things all the more interesting. He still needed to be cautious, of course, since it would be foolish to pit even the smallest or weakest of Nazarick's forces against an unknown threat. To face this sort of challenge was the greater thrill, not to mention the possibility of acquiring something useful upon his victory. A trove of treasure, perhaps, or a large chunk of knowledge? Ainz couldn't wait.

"Ainz-sama…"

"Hn?" Stirred from his thoughts, he was barely able to realize that Albedo had pressed her warm, soft body against his. The "Amelia" disguise had broken partially, revealing the face of the beautiful Overseer, with pale, milky-white skin, black hair and horns and all. A look of worry was etched on her face.

"Is something the matter, my love? I can sense that you are very much distracted. Is it something to do with Shalltear's project?"

He grinned behind his helm and shook his head. "No, I am merely lost in thought, Albedo. Though I do thank you for showing concern, but it is nothing to worry about." He felt bad about making a subordinate worry, as that would mean he wasn't doing his job as "Lord Ainz" well enough. So thinking, he reached out to cup the Overseer's cheeks, rubbing along her face.

Albedo gasped, before she pushed her cheeks against his palm, almost like a cat's. She even made a purr similar to a cat's, though that might have just been his imagination. She shook her head, making the disguise dispel entirely. As he watched, bemused, the Overseer began tugging at her clothes, then moved to position herself between his legs.

"…What are you doing?"

"I thought we'd have a little fun before we arrive at the town," she said, smiling mischievously.

"You little minx. Are you trying to suck me dry before Solution can?"

The two of them were on their way to Kubern, the estate that the Kingdom had granted Solution in her guise as Momon's "sister", Lady Vanessa. As Sebas Tian had indicated in his separate reports to Demiurge, the Pleiades maid had demonstrated a remarkable mastery of subterfuge, and was thus due to be rewarded. Of course, Solution Epsilon had already indicated what her reward was to be a long time ago. Ainz therefore had to "oblige" her, as he did for her sister Nabe.

"Would that really be such a bad thing, my love?" she said, her eyes fluttering.

He cocked his head. "So even after agreeing long before, you still have some reservations, huh?"

Albedo pouted. "There is no woman who would not become possessive over her man. Then again, any woman would be proud to share your magnificence, my lord, provided she remain the first in your heart. These are the thoughts that my heart entertains, every second of every day."

"I see." He patted her head, while her mouth clamped down firmly around the bulbous tip of his human erection. "I'm glad to receive your love."

What surprised him first was the crowd that existed right there in the path that led up to Solution's mansion. Seeing as he and Albedo were here in their function as adamantite-level adventurers, he couldn't just order the disguised minion out front to run right over the humans. He therefore had to stop and then poke his head out, drawing the attention of the noisy gathering. "Stay here, Albedo," he ordered. "And keep watch." It was a minor precaution, to ensure swift flight if anything went wrong in here. At a signal from him, Albedo would order the minion of Nazarick to unveil the invisibility that kept the Soul Eaters pulling the carriage.

"Who's that?"

"An adventurer?"

"So soon…?"

"It's worse than we thought!"

Perplexed by the fearful and anxious faces arrayed around him, Ainz walked forward smartly, his arms raised up to display nonaggression.

"Greetings, citizens. I am Momon, an adventurer come to visit the Lady Vanessa, who is supposed to live here." He looked around, gauging their reactions to him. "Is there trouble? Has something happened?"

"It's been dark news and dark tidings afoot, master adventurer," said one of the men. "Dark creatures from the depths of the earth come to hunt our souls, while Her Ladyship does nothing about it!" He spat onto the ground.

"Oi, oi, that's not true, did you not see that other adventurer group that came here?"

"Aye, those ladies."

"I'm sorry," Ainz ventured. "But did you mention—other adventurers?"

"We don't know their names," was the reply. "But just this morning they came up the road, all the same as you, good sir, and then went into the mansion. Very fortunate, bless the gods, that they'd come, or we'd have all despaired at being prey for the blasted beasts."

That was strange. Neither Solution Epsilon nor Sebas had reported something like this, which made it all the more unusual. "I see. Well, do let us pass on toward the mansion then. I need to have a talk with the Lady Vanessa myself." After much grumbling, the group of commoners walked to the side, freeing up the road for the carriage. "I am very much obliged to you, good citizens," Ainz said, before turning about to re-enter the carriage.

"Have you tried…?"

"I am contacting Solution Epsilon now," Albedo said promptly. She had overheard the exchange, as he had expected she would. Ainz nodded, as the carriage continued onward. It was unnerving to think that there were other adventurers who might have become aware of the estate's hidden dangers. At the worst, they were meddlers who needed to be chased out of the estate before any of them discovered Solution's or Sebas' true natures.

"Solution Epsilon," came Albedo's voice, laced with reproach. "We are already here, in your estate. What is this we have heard of adventurers here? Why have you not reported this to us promptly?"

Ainz stared at Albedo's face intently, curiosity burning within him. He was then surprised when the Overseer's eyes widened with shock.

"Is that confirmed?" After a pause, Albedo turned to him. "Lord Ainz, my apologies for bearing this news, but it seems the group who came here… was Blue Rose."

"Blue Rose?" he repeated, with a gasp. His mind ran, overflowing with his thoughts. He looked out the window, where the mansion was now steadily coming closer. "Why would they… What are they even doing here?"

Inside the mansion, Solution Epsilon was there, waiting, disguised in her usual "Lady Vanessa" form. All around her, Ainz could sense the various shadow demons that had been assigned as her escort, along with the Eight-Edge Assassins he'd allowed Demiurge to deploy when he had asked.

"…What are you wearing?" he asked first, his eyebrows shooting up at the sight. Instead of being garbed in a noblewoman's attire, as he'd thought she would be, she was now wearing some sort of battle-armor, scaled in appearance, with the color of dark brown. The armor looked light enough for her to wear, which made him suspect it was some sort of leather ensemble, similar to what he'd given "Yuki", the human formerly known as Clementine. Attached to her waist were several dagger sheathes.

"This is the battle gear that was recommended to me by Demiurge, Lord Ainz," Solution said crisply. "It allows me greater freedom of movement without sacrificing the subterfuge you have enforced."

"I see." He cast a cursory eye over the items, and saw that they were indeed low-level things—where did Demiurge even find this? Had he borrowed from the treasury?

In any case, this wouldn't do. Although he didn't doubt her capabilities as one who was created by his friends, it was still poor protection for anything that might be a danger to her, like this mysterious underground force. He vowed to find something far more suitable for her to wear, which would offer far more protection while still allowing her to deceive Ainz's enemies.

"My deepest apologies for this situation, my lord," Solution continued. "I have no excuse. But I will state that it was Sebas Tian who insisted that I keep them here instead of driving them out of the mansion."

"Quite right that you didn't," Albedo remarked, her face cold and demanding.

Solution looked to the Overseer with narrowed eyes. "…Lady Albedo."

"Blue Rose is, for now, temporarily, an ally," Albedo explained. "It would have been… understandable for you to have thrown them out, but in the long run it would not have looked good for Lord Ainz's Momon façade, as well as your own. Rumors would have spread of your attitude, granting you a certain infamy in the Kingdom; this infamy is the last thing you should want if you are to follow Lord Ainz's orders." She then shrugged, and smiled with a cruel tint. "But perhaps this was all too much for a beginner like you to handle. At least you had Sebas to guide you, you should be grateful to him that you didn't commit such an egregious error."

By the end of it, it seemed to Ainz like Solution would just pounce on Albedo, but when he looked again, she was as expressionless as ever. After Albedo was done, the maid bowed. "…Certainly. It was my inexperience that nearly led us to that point. I am grateful for your words of guidance."

Sensing that Albedo was about to go off on another tirade, Ainz instead cut in and said, "Where is Sebas?"

Solution's expression lightened when she looked back at him. "Sebas was protecting the entrance to the underground labyrinth when Blue Rose came and demanded they enter. As he sensed that fighting them would be contrary to your orders," Solution bowed to Albedo pointedly, "He instead offered to 'escort' them, while pretending to be clueless about the whole thing. The shadow demons have been relaying the information that Blue Rose possesses to me over the past hour."

"How did they even know?" Ainz muttered.

"It was one of them. Evileye, I assume you know her, Lord Ainz? She sensed the presence of the underground, and convinced the others to investigate. As of now, they're taking it slow, and are at the second 'level'. They've encountered and investigated the magic barriers, but have done nothing about them yet."

"Hm. This makes it a bit easier to 'encounter' them below. Albedo, our story remains as ever. We are 'surprised' by their presence, and we should then insist on bringing them back to the surface. Use whatever charm you have over Lakyus." He hesitated, then said, "And call Shalltear. Have her return to Nazarick, and link up with others who can give her mana. Then call Demiurge and have him prepare all the strongest magic casters ready to go through the Gate. When I give the signal, Shalltear will bring them here."

"Yes, Lord Ainz," Albedo said, though she looked puzzled.

He was unsure that his mastery over deception and illusions would work on these unknown creatures, and thus had to rely on the more esoteric and mundane arts of the Nazarick NPCs to assist him with anything he could not do, such as bringing down the barrier. His strongest magic-oriented morph certainly had spells that would match his old friend Ulbert Allain Odle's—at 80% efficiency—but he wouldn't know if such spells would even be useful now. Of course, he could not just explore and investigate while Blue Rose was here. They had to leave, and so he and Albedo had to "rescue" them, without arousing their suspicions any further.

"Urgency! Urgency!" bleated the dark form of the shadow demon that emerged in their midst. "A barrier has dissolved, and our foes have begun an attack! Blue Rose has been ambushed!"

"Tch!" Now of all times? And Sebas was with them, too. He had no doubts the butler would survive, but he would not act knowing it would reveal his capabilities to Blue Rose. Knowing his deep-seated loyalty to orders, he would act as the same butler he posed, which meant he could do nothing to protect Blue Rose. "Albedo, finish up the preparations, then follow along! The rest of you, with me!" He leaped into action, speeding through the halls to reach the cellar. There, he saw that the hatch leading downwards had been opened, which allowed him to descend down into the dark depths.

It was a nightmare only one of them had ever experienced, and even then, it was Evileye's most desperate wish never to experience it ever again.

The enemy were stunted shapes, humanoid-like figures twisted into fearsome, unimaginable mockeries of what was good and right and natural. They did not fear the banishing sorceries from Lakyus, nor were they fazed by the bite of the twins' blades, nor Gagaran's mighty blows. Only her powerful protective magics kept them safe: turned their rusty, jagged blades aside, or frustrated their ghoulish jaws, each tipped in uneven, razor-sharp teeth.

It was a rout, from the onset. They did keep pace, warding off the creatures while ensuring their formation never broke, that not one of them was suddenly overwhelmed and cornered. Yet it could not be denied that it was a rout: a defensive sort of rout, and their only solace was that the area behind them was not swarming with the creatures.

They were also working to ensure that the amiable elderly butler, who had shirked his master's command and allowed them to investigate these depths, was adequately protected. A cynical part of Evileye's mind thought that should the situation come to it they would be better off sacrificing the old man to ensure that Blue Rose was saved, but she knew even she could not stomach that "unheroic" action—not to mention Lakyus would never ever do it.

"Arggh! This is ridiculous! They're godsdamned everywhere!" Gagaran shouted. "I'm going to need a couple more shots in me if we're going to keep up this dance for much longer!" Her armor was slick with blood and offal.

"Evileye, can you not collapse the tunnel?" Lakyus asked.

"You wouldn't want me to do that, leader!" she shouted back. "In case you don't know, I haven't worked as a miner in all my life! We'd be liable to collapse the whole thing over our heads!"

"Even if we reach the exit, we'd still need to prevent these things from spilling out into the world outside!" Lakyus continued. "Sebas sir, would you be willing to run back and inform your mistress on the situation? Have her ask around, and see if there is any way you could seal the cellar entrance permanently."

The old man seemed to hesitate, before nodding. "Aye. I shall do my best…!" He turned and ran, a little swifter than expected.

"Leader," Tia said. "You didn't mention anything about us getting out of here."

"Shush, sister," Tina said.

Evileye resisted the urge to grin maniacally. Everyone in Blue Rose seemed to have reached the same conclusion in their minds. Though they were working towards a solution, the most possible outcome still stood out in their minds. If they, an adamantite-level adventurer group, could not handle this threat, then much of humanity outside would surely not be able to. Letting these things escape, at least without alerting humanity's strongest, would only mean innumerable death and tragedy throughout the land, mirroring the events of the Demon God invasion long ago. As Blue Rose, they had a definite responsibility to humanity, their lives be damned. They would nip this in the bud, no matter the cost.

"I shan't lose hope yet, my friends!" Lakyus said. She channeled magical energy into her blade, then discharged it outward in a wave of light that slashed through several creatures, bisecting them in half. "This battle has yet to be lost! We fight on, Blue Rose!"

"Aye!" they screamed in unison.

"I can't die yet you fucks!" Gagaran cried. "Not until I've seen every last one of my friends deflowered in some way or another! That includes you, midget!"

"Hush, oaf!"

"And even I ain't dying until I manage to get one good, raunchy evening with sir Momon!" Gagaran continued.

Despite their grim bravado, their running battle continued without any of them managing to rest. Even Evileye, who possessed unnatural vitality, found herself winded and pushed to the brink, as if she had finally reached some invisible limit to her strength. They had already retreated all the way to the first level, leaving many of their enemies dead at their feet, and yet still they came.

This isn't going to work, Evileye thought. She turned her thoughts towards using "that": her trump card, a catastrophic spell that would surely doom Blue Rose. It would also be her last act, as even she did not know the effects the spell would have on its own caster.

Yet just as she had summoned the nerve to do it, all without telling her team-mates, a cold voice rang out from behind them. "To the sides, Blue Rose!"

Long-honed instinct made them jump instinctively, pinning their bodies against the wall without a thought before they even thought to look back. And when they did, they could barely catch a glimpse of something that instantly zoomed past them, like a flash of lightning too fast for the naked eye.

A loud, thunderous boom shook the tunnels, as the earth shuddered underneath them. Immediately they recognized the silhouette of the black armor that now stood in front of the hordes, wielding a great silver shield before him.

"Momon!"

As Blue Rose stood gaping, they were then surprised by the arrival of the mistress of the house, Lady Vanessa, now clad in battle armor. Her stance was low, her hands each holding sharp blades that glittered in the dimness.

Then, someone else came that made Lakyus' face flood the tunnels with light.

"And Amelia!"

"Greetings Blue Rose," she greeted. Her blade was also bared, and she glanced around them before nodding. "Come. We've heard the details from the villagers. Fortunately, Momon has consulted with Vanessa, and we've concocted a plan, of sorts."

"What sort of plan?" Evileye asked.

"A stronger magic seal, whose details I do not rightly know. It is a ritual bound to their blood. It shall create a barrier that we believe shall be impregnable. This will buy us some time to study this foe. For now, I must ask you to return with me. I aim to create a last stand in case…" her voice faltered. "In the event something goes wrong. A backup plan."

"Oh joy," Evileye quipped drily.

"But we cannot just abandon Momon and the Lady Vanessa!" Lakyus protested. "We can help! Combined, our two groups may just—"

"Lakyus!" Amelia snapped, in a tone that somehow caused their leader to jerk back. "Please. I implore you," she continued. "We do not have time."

Lakyus bit her lip, glanced back at Momon, who was already driving forward with his shield, while his blade slashed back and forth, illuminating the dark with brilliant flashes of light. "Blue Rose," she intoned then. "Fall back."

"Leader…!"

"Fall back!" she said. "We need to regroup. If Eclipse Nebula indeed has a plan, it is not our place to disrupt it with bickering. Move!"

They all ran after Amelia, who ran back to the area beneath the cellar. Evileye glanced back, and frowned. She had a bad feeling about this, but she didn't have the time to doubt their blessings.

"Are they gone?" Ainz asked, as soon as the last of the footprints faded.

"Yes, my lord," Solution said. Immediately he released the invisibility field that he'd conjured around the gathered shadow demons and the Eight-Edge Assassins. Although possessed of greater stealth capabilities, they would perhaps still have been sensed through some unknown means by Blue Rose. With them out of the way, Ainz immediately cast an illusory replica of the previous scene, with him holding back the hordes and Solution right behind him, so that anyone who might've walked back would have seen only that.

"Stand by," he muttered, before fully focusing his attention on the enemies. Through basic inspection, he saw these were just a bit low-level for him, and yet they had properties that puzzled him. In terms of sheer power, they could slowly wear down one of the Pleiades. Even the maids working together as a full group would become hard-pressed.

There were, after all, just too many.

He morphed into his preferred form, suited for multiple enemies. It was only used for farming back in Yggdrasil, and he had then recently modified it, after experiencing battles.

Six arms. Six blades. Arms imbued with the strength of ogres. Body lithe and segmented, like an insect. Carapace hard as mithril, enchanted against curses and demonic attack, and imbued with the miasma of a fiend, ensuring all blows would only strike back against the attacker.

"Spin Strike!" Ainz called out, and in the next second the impromptu shield disappeared, and he began spinning like a top. Like a deadly blender he plunged into the fray and processed the insidious meat of these subterranean intruders with bloody, gore-slick ease. Steadily he advanced, his spinning arms never letting even a single foe escape his wrath. They could not even muster an attack, which would still have met the steel he now bared—each of the blades had been "failures", gifted to him by Warrior Takemikazuchi after being deemed unworthy for sparring against the World Champion. And yet he saw the true potential lying within these blades, and knew he could not just throw them away.

Here in this new world, their data made them frightfully effective. They cleaved through the stone walls as the tunnel narrowed above and on his sides. They were unhindered by blood and fat, perhaps even striking through to his enemies' souls, cutting them to pieces.

He laughed. "I can do this all day!" And he could. This was no challenge. He'd only get bored.

Suddenly, a loud rumbling roar echoed through the tunnels. The sound was so deep and piercing that even he stopped, as if the sound had reached down to grasp his heart. Then the feeling passed, like heat during a cold day, and he knew this was the effect of terror passing harmlessly through his enchanted armor. That he could still feel a slight twinge made him pause to consider the situation around him.

By the looks of it, he was in an area far beyond where he'd encountered Blue Rose. Before him was some sort of shimmering wall, which gleamed in the darkness with a sinister light. As he shifted his eyesight to that of an under-vermin's, he could see that the remnants of the horde now scurried back through the barrier, as if fleeing him—or perhaps following some new orders.

He gave chase, and smashed his swords against the barrier. To his surprise, the wall held, which was honestly quite shocking. He reeled back, to process it. This was impossible. The blades that were fit for a level 100 to wield were useless against the barrier. Either there was some sort of incompatibility at hand (like his blades had an element that was completely immunized by the barrier's own element), or the barrier contained data that defied the blades itself.

Ainz smiled. "I see. Then let us test this."

He drew his blades into a pattern, which he had mimicked from another guildmate, who was specialized in fist-fighter classes. "Six Fold Realms of Destruction!" he shouted, fulfilling the formation, as each blade shout out a bolt of fiery energy that struck at the outsides of the barrier, on the part where it met the tunnel wall. There was a loud boom, and the barrier flickered, and yet the tunnel now rumbled around him ominously.

"I see," he murmured, seeing the barrier wink in and out like a star. It seemed brute force could render the supports on the barrier unstable, which meant that the implements that powered it were just close. Then, the whole thing came crashing down, but not before Ainz had leaped through, slashing the rubble into dust. "Let's see what's behind all this," he thought.

Beyond, the rough-carved tunnels gave way to walls that were smoother, and obviously man-made, along with strange runes and carvings. He could tell that complete darkness had shrouded this place entirely, as his darkvision was completely active, and showing him a tinted view of his surroundings. The pathway was filled with blood, no doubt from the creatures that had just fled his coming. Eventually, the deserted halls gave way to a larger room.

There, he saw something that indeed gave him pause.

A large mass writhed in the center, moving and pulsing like a living mountain of flesh. As Ainz's eyes adjusted, he could see that it had a vaguely humanoid face, almost reminiscent of a severly obese man, or even vaguely pig-like. It towered high above Ainz, almost thrice his size, and wielded a blade that was seemingly just a huge slab of iron, thick and wide and jagged. A constant wheezing sound came from its maw, which exhaled some sort of foul, nauseating breath that Ainz could smell, making him shut off his sense of smell entirely with a morph.

"Are you the leader of this place?" he asked, his voice echoing into the darkness. The beast only howled in response, and it was the same terrifying sound that he had heard just before. Then it charged, moving on its maggot-like legs and hefting its large chunk of metal up to crash down on him.

Ainz made one last set of morphs to adjust, replaced some of his weapons, then leaped upward, meeting this new challenge head on, battle-lust ringing like an exhilarating sound to his mind.

As he fought, he was aware of the constant mind-affecting statuses that bombarded him, only deflected by his superior gear. It seemed that aside from brute strength, the fiend also relied on effects that would affect the mind. His own terror-inducing illusions had no effect on the massive creature, though other types of illusions, like summoning a decoy, had successfully confused it.

After running full circles around the creature, and scoring what was perhaps a thousand hits on its putrid flesh, his enemy wailed out loud in a bawling voice. The next thing he knew, the whole chamber was collapsing, and it was all Ainz could do to flee backwards on many legs.

A moment later, when it had all seemingly settled down, he came back, and saw that for some reason the floor beneath the chamber had given way, making the strange pig creature fall straight down into the abyss with one last hideous squeal. Ainz walked over to the edge, and there found no sign of his foe, only a deep yawning hole, where even his darkvision could not penetrate its inky depths.

He grunted, feeling a sense of frustration as deep and unfathomable as the newly made abyss. There was nothing to show of his efforts but the blood on his blade. No corpse to loot, nor body parts to harvest. There was not even a visual indication that he had gained "experience"! And he wasn't even sure that his enemy was dead, merely gone, and might be relaying valuable information about him back to the depths. If it had a master, it must surely be learning much about Ainz, and that made him all the angrier.

So wild and rampant were his thoughts that he hadn't even noticed Solution walking up behind him. It was only when she spoke that he was jerked back to the present, and his attentions turned towards the maid.

"Is everything alright, master?" she asked, her eyes traveling all over the place. "I do not detect any hostiles."

"Hm." He shook his head. "No. For now, they have retreated."

"You are indeed strong, my lord," she exclaimed.

Ainz sighed, putting away his weapons as he reverted to "Momon"'s shape. He turned and placed his hand on top of Solution's head. "Now that I see it, you are a splendid specimen, Solution Epsilon. Herohero-san created you well." He began stroking her hair, which made the maid's whole body quiver like jelly. He smiled, and almost wanted to take her, there and then, but he recognized the stupidity of getting caught dead with his pants down, with his cock buried deep in some woman's cunt. Instead, he patted her back, whispered, "Let us continue after this," then ordered Shalltear via Message to begin deploying the magic casters.

Loathe as he was to abandon further exploration, he yet needed to quell the chaos caused by these subterranean creatures by bolstering the defenses. To that end, a three-tiered array of defenses were raised in the tunnels, each a specialized effort by different NPCs of Nazarick. The forge-masters from Demiurge's domain created a physical wall that only a high-level creature could breach: its destruction would then trigger an alarm within Nazarick itself, most especially those who could cast Gate like Shalltear—they were to deploy immediately.

In such an event they were then to gather behind the second barrier, erected by an array of magic casters to resist all forms of assault. They would wait, study, harass the foe, until it was breached, or if Ainz himself decided to take the field, as he did today.

As such, the third barrier would never be used—as it would signal the NPCs' defeat, which was itself a bad thing, or Ainz retreating from a superior foe, which was many times worse. It was something Ainz had made himself, supported by the magic casters of Nazarick, to create a formidable illusion that would fool the intruders for a long time. He laughed in his heart at his construction, like a child who had created something unorthodox out of Lego blocks. He then bid the NPCs return to their duties, while skillfully dodging an attempt at a kiss from Shalltear.

All in all, he was pleased, if somewhat still frustrated.

Fortunately, there was something he could do to alleviate that frustration.

While they recuperated, Amelia had gone off somewhere in the mansion, causing Lakyus to wonder out loud where she'd gone. After enduring minutes of a tired Gagaran endlessly needling their leader about the coming marriage, the woman in question returned, bearing a soft smile.

"You will be glad to learn that sir Momon and Lady Vanessa have accomplished the ritual. Please refrain from returning to the area below so as not to disturb their work."

"What on earth did they do?" Evileye asked. "Whatever they did, it sure has to be strong enough to hold against that horde. I'm not even sure if they could manage it."

"The Lady Vanessa has herself attested to the safety of the barrier. Beyond that—well, it is a matter for the Lady herself to decide." That was true. It was entirely possible that the newly endowed woman would choose to sell the estate rather than stay on top of it.

"Are they alright?" Lakyus asked.

"It seems so," Amelia replied. "As ever, my lord's martial prowess was more than enough to hold back those fiends. It was long enough for the Lady Vanessa to initiate the ritual, and for my lord to complete it."

"Tell me, Amelia, what is the relationship between sir Momon and the Lady Vanessa?" Lakyus asked. "I will not conceal the fact that I came here expressly to learn more about that, as soon enough she will become part of my extended family. Would you be able to enlighten us?"

Amelia looked surprised, before smiling. "So that is why you're here? Fufu…" The woman crossed her arms. "Let's just say that though the Lady might act harsh and aloof to her brother, deep inside she does harbor great love and respect and admiration for him. That was true for everyone who well knew our lord—in that distant realm we call home."

"So there's no bad blood?"

"Aye. One might even say that they're… exceptionally close."

"Hahh… Ahhh… Haaaah! Lord Ainz…! Lord Ainz…!"

The rhythmic slapping sound was like meat being slapped against the board.

Making love to Solution was quite a different experience from the others he had already conquered. It could not be denied that each had their charms: Albedo was, in his opinion, most alluring and beautiful of all, and Nabe had a way with her tongue that made her mouth an exquisite blowjob experience. Touching Solution, wrapping his arms around her and kissing her felt very much distinct, and this was perhaps because of her uniqueness. Whichever part of his body touched hers turned into a heated erogenous zone that repeatedly sent waves of pleasure coursing through his nerves.

From the outset the way his hands sank into her body felt like he was pitting his hands inside jelly. Living jelly, on top of that, for it was as if there were a hundred thousand lips each kissing and licking against his touch, which was itself a novel experience for just his hand. But pair that against one's sensitive genitals, and the maid managed to almost make him cum right there and then. And her kiss wasn't any different, challenging him with a warm, enveloping sensations of those miniature suckling, licking tongues dancing in the thousands inside his mouth. In fact, it was as if her entire body was a living amalgamation of tongues, which excited Ainz greatly.

When they returned from the basement Ainz immediately led Solution over to the closest room, which was the parlor. He ordered every other minion out, including Sebas, before casting an illusion spell on the door. Then he set his sights on devouring the Pleiades, who awaited his pleasure with smoldering eyes of blue. He took her in his arms, caressing her sexy curves and there found the aforementioned softness of her body, into which his fingers sank easily. With every squeeze and caress, the maid's body moved and humped against him, until he kissed her, and their lovemaking began in earnest.

There was no need to "undress" her, for even her original form in Nazarick was but an illusion crafted by Herohero, to conceal her monstrous nature. So touching the uniform was already like touching her skin to skin, and it was thus that he immediately sucked on her teats, which felt like twin jelly-like slabs whose surface emanated the writhing velvet-like nature of her body. She moaned as he bit and chewed on her flesh, leaving behind fat, visible marks on her skin that didn't fade (and if it was supposed to then perhaps, she never wanted to).

"My lord… please bestow upon me your blessing… Lord Ainz…!" Solution pleaded, as she sank to her knees. A soft, squishy tendril snaked around his crotch, urging him to expose his manhood.

And this he did, slapping the maid across the cheek with the full force of many inches of hyper-sized dong. The force caused her face to distort, and yet nevertheless she smiled, especially when she swallowed him. She was able to take him deep in her throat without difficulty, taking his cock all the way to the base and even up to his balls without effort. Being inside her was like being wrapped in an ocean of neverending pleasure. It wasn't much kissing as tasting, as if she was savoring him as a meal before devouring him entirely. For Ainz, it was like he had stuck his member into something alive and ravenous. She had no technique to speak of, but her efforts nonetheless quickly drove him to orgasm all the same.

He tried to drive off her head, but she stubbornly stuck to him like a lamprey, refusing to be cowed, even by his strength (though he was holding back the whole time). She made it her own duty to force him to cum inside, which he did, exploding in one large burst. Unlike an ordinary mouth, which he could feel constrict and struggle to hold back his seed, cumming inside Solution was like he was peeing into a pool, as he could feel his warmth spreading throughout her entire body like ink spilling through water.

"Ahn… Lord Ainz… So delicious… so wonderful…" She muttered, as if she were eating something fresh and tasty. After a while, she moved away from him, letting him out with a loud muffled pop of her lips.

Solution presented her cunt, a faint, pinkish entrance on her flesh that accurately mimicked the real thing. Though she was technically a virgin, Ainz encountered no virginal experience here; for instead he plunged into her and was once more greeted by pulsing, squeezing love: gooey, rapturous, slick, and ravenous. It was like a second mouth, almost, and perhaps that was not too far from the truth. Her pussy coiled and wrapped itself voraciously around him, similar to how her mouth had milked him.

Not to be outdone, he thrust in and out of her with renewed gusto, transforming his dick into a literal scraping tool designed to prickle and stimulate her private insides. He lifted her up, spread her legs and skewered her like a fish. Due to the relative difference in their sizes it was like he was manhandling a small doll, and even his dick seemed like it was impaling Solution right through half of her body. He loved that the contrast that image brought on, which aroused him even further.

"Yes! Uhn…! Hahnn…! Master…! Master…!"

As Solution moaned and gurgled, a far cry from her usual stoic self, Ainz took great pleasure in dissolving that façade, of reducing her to (literal) liquid. He came again with an explosive battlecry, filling her insides once more with his fresh hot seed. He grunted, as her pussy had then begun to actively make hungry, sucking motions, as if it wanted to drain him of every last drop of cum. The presence of his heat was quickly dispersed throughout her body, which in itself seemed to produce a powerful orgasm within the maid, causing her whole body to shiver uncontrollably.

She sagged against his body, and he bore her warm weight ably with his tall, muscular arms. He was still hard, and still entrenched deep within her body. When she stirred back awake, her insides started to actively kiss along his shaft. Looking into her eyes he saw her insatiable hunger, which pleased him greatly.

He slammed her against the wall, and then pounded into her tight, velvety crevasse with all the might he could muster.

Outside their voices could have easily been heard, for Solution Epsilon was a screamer, and Ainz was not that keen on being subtle with the way he drove relentlessly into the maid's body, uncaring of the many sounds that created—sounds that would be familiar to anyone who overheard, making them realize what was going on immediately.

It would have been the case: that Blue Rose, who had just gathered outside the parlor on the way to their rooms upon Albedo's invitation, would have quickly overheard the rampant sounds of sex from the parlor. But Ainz had been prudent in masking the room with his own formidable illusion.

What they only heard was voices raised in great emotion, muffled by the door and all implicating noise removed or dulled out to anyone listening.

"Yes!" Slam. "Yes!" Slam. "Yaaahhhhnnn~!" Slam! Slam! Slam!

"If I didn't know better I'd say those siblings sound like they're doing the two-backed beast," Gagaran observed with a sly smirk.

"I do apologize for that," Albedo said, "Though I said that they are indeed close, it is far too easy for things between them to erupt into a long and loud argument."

"Come, Blue Rose. Let us not be voyeurs," Lakyus said.

As they left, Solution's voice kept on going, "Ainz-sama..! Fuck me! Breed me! Ahh~ Ahhhh~ Ainz-sama…!", although no one heard. And it was thus that the noises continued—through the evening, in tune with Albedo playing with her pet human in the bathroom—and onwards until early morning, when Ainz was satisfied that Solution was satisfied: by becoming a literal puddle on the floor, her form sufficiently glutted with his cum like water stained with oil.
