In the throne room of the Great Underground Tomb of Nazarick stood three heteromorphic beings: A skeletal overlord, a doppelganger, and a destagiest possesing a human body. They wanted as little people as possible to see this.

Ainz turned to the corner of the the throne room and lifted the staff of Ainz Ooal Gown in the air. The gems in each of the seven serpents mouth's gleamed.

"Entoma Vasilissa Zeta, resurrect!"

The mountain of 50 million gold coins turned from a solid pile into a flowing metal river. The softly glowing golden river coalesced into the shape of young heteromorphic girl. Her silhouette looked like human who had two extra sets of limbs sprouting from her back. The glow disappeared to reveal the head of an arachnid, sitting in it were four pairs of varying sized compound eyes. Her naked body was black exoskeleton, riddled with thin, spider-like hairs.

The air in the room was solemnly sacred, and Ainz and Pandora's Actor knew generally what to expect Entoma's true form to look like, but nevertheless, they flinched when they saw her face.

Genjiro took a deep breath. He walked up to the supine Entoma, he did his best to give the girl a warm smile.

The girl's compound eyes filled with color. Her lip bug was long gone and she spoke in her natural voice, it was grating, but it was soft and subdued. It was like a rusted merry-go-round heard from across the park, a voice that was rasping and in disrepair, but still capable of bringing joy, it was beautiful to Genjiro's ears.

"...wHeRe aM I?"

Genjiro crouched down and did his best to maintain his quivering smile, "Welcome back, Entoma dear."

"...WeLcOmE bAck…?"

She realized that she was lying naked on the throne room floor. Her memories came flooding back to her. Her humanoid-insectoid biology permitted tear ducts on her compound eyes, her voice cracked as she fought back her shame and tears.

"...I-I, I FaiLeD NaZArIck…"

"Nonsense." He embraced her, wrapping his grey cloak around her delicate frame. His eyelids were closed tightly, holding back the tears that were forming behind them.

"I'm sorry, It's all my fault."

"G-GeNjiRo-SaMa-"

"I-If I had written your personality differently so that you would run away, or if I had changed your build so that you could fight better, or if I hadn't given you that dynamite, or if I had simply gone with you-"

"gEnJiRo-sAmA!" She cried profusely. She wasn't sure if it was because she couldn't bear to hear her creator's ashamed and tortured voice, or because of her own shame for being defeated in combat. But regardless, she wanted to comfort her creator and in turn to be comforted by him.

She wrapped he limbs around him and soaked him in tears. Genjiro did the same.

The overlord and the doppelganger watched the bizarre scene of a naked humanoid-spider and a human-destageist crying and embracing each other on the throne room floor. It was obvious to them that they loved eachother very much.

Ainz watched them with painfully mixed feelings. Regret, Shame, Relief, Affection, Guilt.

Pandora's Actor felt a pain in the back of his neck. He empathized painfully with the girl, he could only begin to imagine the shame she must be feeling, to fail in combat only to be resurrected in her creators arms. He wondered how Ainz would react were he to befall a similar fate.

Ainz signalled him and they quietly left the room so that they could give them some privacy.

.

Genjiro had discovered that possessing an elder pink ooze was an effective way of regulating his emotions. Unlike his undead boyless form which forcefully cut off strong emotions, his pink ooze body seemed to regulate them in a very organic way, his mind was subdued and emotions gently calmed down over time.

He sat in a slimy puddle in Ainz's study.

They both tried to speak at the same time.

"I'm sorry."

"I'm sorry-."

"Oh wait, you can go-"

Ainz put his hands up. "Wait, sorry, please, go ahead, Genjiro-san."

Genjiro bowed in the best way his amorphous body would permit. "I'm sorry Ainz, and I apologize to Demiurge as well who wouldn't take an apology from me. I already knew all along that she could be resurrected, and yet I still let my emotions get the better of me. I over reacted. I'm sorry."

"I'm sorry too."

"But have nothing to be sorry for-"

"I do though. This all might've been avoided if I hadn't forced you to go on that mission. You would've been teaching Entom and Demiurge might've not chosen her for his plans."

"That's not your fault though-"

"But it is. I'm sorry Genjiro-san, I guess… I guess I was jealous."

"Jealous?"

Ainz put his bony hand on his fleshless face and chuckled mockingly at himself.

"I was unbelievably happy when I saw that one of my friends had returned and had come to this world with me." Ainz had no doubt that if he had a human face, he would be blushing furiously.

"I guess I just really missed you, and when you chose to spend so much time with Entoma rather than me, I guess I got jealous. Some part of me was really annoyed and wanted to separate you. I guess our personalities really have changed since coming to this world."

He recalled the scene earlier in the throne room. How stupid he had been to try and mess with that kind of love, even if he was only doing subconsciously. He continued to ruefully mock himself.

"I-I see, wait no, that's my fault too." His slimy form sunk closer to the ground, "I should've spent more time with. I'm sorry, my friend."

"No, please, get up, It's not your fault, I was being petty."

Genjiro chuckled lightly, he had forgotten about how much of a lovable push over Ainz was.

"Same old Momonga. You just can't accept an apology can you?"

Ainz stopped and laughed lightly together with his friend. Somethings never really do change.

The air in the room had lightened and they enjoyed each other's company, the reminisced about their fun times together.

Genjiro got up to leave, work was an inevitability, regardless of what world one existed in.

"I guess I should get going now, we both still have loads of work to do."

"Yeah… Hey, Genjiro-san, are you sure you don't want to know the ones who did it? We could capture them at once with only a moment's notice."

Genjiro shook his slimy head. "No… I think it's best that we all forget about this. I don't know if I'll be able to control my emotions next time."

"I see, in that case, take care."

"You too."

Genjiro teleported away using his ring of Ainz Ooal Gown. Ainz was happy, he finally had his friend back.

.

.

Genjiro was the spitting image of a wealthy medieval businessman. He wore a light blue doublet complete with padded shoulders and extended sleeves. At his waist was a pair of tight fitting pants that hugged his body all the way down until they ended in a pair of tall buckled boots. Atop his head was a fine fur hat that perfectly concealed his hair. It was a simple but professional outfit.

Across from him was a young and fox-like man adorned with even more opulence. He wore loose fitting clothes made entirely of silk and furs. Around his neck was a gold necklace embellished with a massive walnut-sized gemstone and his fingers were practically encrusted with gold and silver. He perfectly matched the image one would expect to see from a member of the "Six Great Nobles of Re-Estize".

"So then, as agreed, here is the down payment, Mr. Zen." The fox-like man placed a small pouch of gold and platinum coins on the desk. "The rest will arrive once I've seen the rifles and the powder."

"Of course, it's a pleasure doing buisness with you Count Lytton. And I must say again that I'm honored to have such a busy and important man like you come all the way down to E-Rantel personally."

"The pleasure is all mine." Lytton hid his mischievous smile as he eyed Zen's beautiful assistant Ellie, who had been standing silently in the corner of the room.

They stood and shook hands.

As Lytton was exiting the room, Zen stood and bowed along with Ellie. Once the door closed, Zen fell back down into his chair, exhausted.

"What a pedophilic sleeze bag, I could've sworn he was going to ask how much I would be willing to sell you for."

Entoma was wearing a light blue kimono-esque dress and a silk cap that hid her antena. She walked over to her creator, "dO YoU WAnt ME tO kIll HIm, GEnJIrO-SaMA?"

"No, no. As much as I don't like it, we need trash like him alive. Because of their involvement in the demonic disturbance, the popularity of firearms is through the roof. And because the security division of the eight-fingers is no more, many of the wealthier people have been trying to outfit their own private forces with rifles."

Genjiro took his hat off and ran his fingers through his hair. "We need to appear as a professional and legitimate business so that nobles and royalty can put their trust in us. And that includes not killing people and wearing these tacky clothes."

He stood and picked up the pouch of coins on the desk. He then placed his hand on Entoma's capped head, "Anyways, that was the last noble for today, let's go shopping."

.

Zen and Ellie walked side by side through E-Rantel's busy streets as they made their way towards the Aarden Mining Company.

Although they were right next to each other, they were conversing via [Message], not only because they were discussing the forbidden knowledge known as science, but also because Entoma's voice would be a clear give away that they weren't human.

"When manufacturing different kinds of chemicals, you'll often need to use something called a catalyst."

"A CaTAlyST?"

"Yes, a catalyst is a material that serves as a surface and helps your desired reaction, but does not actually undergo any chemical changes itself. As such, catalysts can be reused and you usually won't need too much of what ever it is. Regardless, certain specific catalysts are necessary for many of the reactions we have planned."

Zen was marching along next to Ellie with his finger raised like a professor, which looked odd to the onlookers, since to them it looked like he was completely silent.

"For the reaction that creates hydrogen gas from methane(natural gas), well need metallic nickel to serve as a catalyst. And once we mass produce ammonia from that hydrogen gas, we'll need a platinum and rhodium alloy to serve as a catalyst in creating nitric acid."

"nItRiC AcID?"

"Nitric acid: HNO3, It's incredibly useful for making all kinds of things. Along with nitric acid, we'll also want to be mass producing sulfuric acid."

"SuLFuRic AcId toO?"

"Yes, H2SO4. Like nitric acid, it is also incredibly useful. But to mass produce sulfuric acid, we'll want to have a good source of sulfur trioxide."

"iF We WAnt An OXIdE Of sUlfUr, CouLDn't We juSt BurN iT?"

"Yes, very good, but it's a little harder than that. When you burn elemental sulfur, you end up getting mostly sulfur dioxide and only a little bit of sulfur trioxide. So how do you suppose we get more of it?"

"WiTh A CaTAlYSt?"

"Exactly Entoma dear. We can react the sulfur dioxide with oxygen to get more sulfur trioxide using vanadium as a catalyst. And once we have sulfur trioxide, it's only a matter of cleverly mixing it with water to get sulfuric acid.

Anyways, having large quantities of nitric and sulfuric acid at our disposal will be integral to our future prospects."

They turned a corner and saw their destination up ahead, it was a rustic looking brick building sat on the banks of E-Rantel's river near the edge of the city. It was connected to a water wheel which Genjiro assumed was for breaking up the ores that were imported from mines outside the city.

"We could also use some zinc as well. Not only do we need it as a catalyst for another reaction we currently have planned, but also because zinc and zinc oxide are generally useful materials altogether.

So to recap, we're here to shop for metals to serve as catalysts. We'll mostly be looking for nickel, rhodium, vanadium, zinc, and any extra platinum we can get our hands on."

They walked up to the building and opened the door. It triggered a bell. Ding.

It was a bucolic noise and Genjiro felt himself relax a little. He spoke one last thing to Entoma before ending their [Message]. "Your natural voice is very beautiful Entoma dear, but I don't suggest using it in front of humans, but I'm sure you already figured that. We'll find a substitute voice eventually."

He ended the [Message] and waited for someone to arrive at the front desk. The interior of the Aarden Mining Company was rustic and crude, but it still did its best to be organized and tidy which Genjiro could respect.

The walls were brick with and supported by wooden pillars and beams. Inserted in them were large glass windows and shutters that let in natural light from the outside. At the front of the room was a hearty wooden desk and behind it was a chart that displayed the current prices for copper, iron, silver, gold, and platinum, along with other metals such as mythril, oricalchum, and adamantite.

A boorish and irritated voice was heard from the back room, "I'm coming I'm coming."

A gruffy little man came around the corner to greet them. He had messy red hair and a boastfully large beard, and if he was any shorter he could easily be mistaken for a dwarf.

He immediately noticed the rich clothing that Zen and Ellie were wearing and straightened his posture. He did his best to speak polite tone. "Sorry for my tone earlier, you two definitely aren't the dirty smiths I usually get coming through that door. I'm Mr. Aarden, how can I help you?"

"Greetings, my name is Zen and this is my assistant Ellie, I own the Darkness Trading Company that recently opened here in E-Rantel."

Ellie did a curtsy and Aarden gave her a polite nod, remembering the trading company that had appeared out of nowhere and accrued a massive fortune selling mysterious weapons.

"Allow me to get strait to the point, I'm in need of a very particular set of metals."

"A particular set of metals you say?" Aarden leaned in and continued to listen.

"Yes, I'm looking for the metals known as nickel, rhodium, vanadium, and zinc."

Aarden scratched his beard and sighed. "We've got boatloads of zinc, but I've never heard of the other three."

Zen mimicked Aarden's beard scratching, Hmmm yes, it would make sense that he knows what zinc is because it is an important component in making brass, I just didn't expect him to know it under that name. The other three were isolated and named post 17th century however so it would be expected that he wouldn't know about those. In all likelihood, he has probably handled ores containing those metals and has just never isolated or named them.

"Mr. Zen?"

Zen realised he had been standing there silently scratching his chin and stopped his train of thought. "Hmmm? Oh yes, pardon me. I was just thinking that even if you don't recognize the names, it's likely that you have what I seek here."

"I do?"

"Yes, could I have look at all the ores you have here?"

Aarden gave Zen a dubious once over, but decided that he should probably comply out of respect for the mysterious and powerful Darkness Trading Company, and in hopes that he could turn a profit.

"Of course, please follow me."

.

P.S Shalltear cost 500 million gold to resurrect so I don't think 50 million for Entoma is an unreasonable amount.
