[22] : Spirit Piece?

Draconic Deus

Earth – Japan

Kyoto – In a Motel

[***]

Three days later.

Aiden was lying on his bed, wrapped in the sheets, staring intently at the screen of his cell phone.

He had discovered Supernatural.net, a network created exclusively for the supernatural world.

After 100 years trapped in a medieval world, the simple act of connecting to the internet almost brought him to tears of joy.

When Aiden learned about the existence of this network, designed primarily to share gossip and random news among supernatural beings, he couldn't help but feel curious.

Without hesitation, he hypnotized a store employee to sell him several phones, and in the end, he ended up buying eleven devices.

He had to hypnotize the entire store, as such a large purchase required signing documents with personal information—something he couldn't do since he had no identity in this world.

To avoid complications, he left a gold bar as payment, thanking them for their "troubles."

While browsing Supernatural.net, Aiden discovered that his battle against the Great Red in the Pacific Ocean was trending.

The discussion on the forums was heated; there were opinions and theories of all kinds about who he was and what powers he used.

Many believed his <Divine Authorities> were actually [Sacred Gears], weapons or tools created by the God of the Bible for his "children," humans, though they could also be used by hybrids.

'This world is interesting...,' Aiden thought, observing the wealth of material that could inspire a manga.

He remembered that Nia had mentioned something about becoming a mangaka as a profession.

He shrugged mentally.

'Well, she can do whatever she wants. I'll support her. After all, we have to build our lives here.'

He also thought about Miku, who wished to be an idol and upload songs online.

Aiden had no problem with that, as long as no one dared to harm her.

He continued swiping his finger across the screen as sunlight began to filter through the curtains.

'I should create some fake identities for the human world first… That shouldn't be too difficult,' he thought to himself.

He knew Japan was mostly governed by the Shinto Pantheon, but those gods rarely got too involved in human affairs, limiting themselves to offering protection in exchange for faith.

Creating a fake background for them shouldn't be complicated; it would simply take finding a supernatural being willing to help in exchange for money.

'Though it'd be better to go to someone trustworthy or influential,' he reflected aloud.

He quickly dismissed the idea of involving the gods.

Revealing his identity as the one who fought the Great Red would only complicate matters; it could lead to unwanted alliances or problematic demands.

It also wasn't the right time to approach the youkai, though he would eventually consider connecting with them.

'Someone influential who would actually be useful to me...?' he wondered, closing his eyes to concentrate.

A soft movement in the bed distracted him.

He glanced at Mukuro's blonde hair spread across the sheets.

The girl's head rested on his arm as she slept naked to his left.

"Hmm... Nushi-sama~," Mukuro murmured in her sleep, her sultry voice bringing a small smile to his lips.

Aiden gently stroked her head, causing her to open her eyes, still clouded with sleep.

Without a word, Mukuro wrapped herself around him, pressing her body against Aiden's as she gazed at him with adoration.

—Chuu~

The two kissed for a few moments, their tongues intertwining as they fervently sucked on each other's lips.

Around them, the other girls were still sound asleep in the enormous bed.

They were exhausted after the "nightly exercise" from the previous night, even though, ironically, they didn't have permanent physical bodies.

Even so, they could feel fatigue like any living being.

"Ahhn~♡"

"Nushi-sama~♡," Mukuro moaned unabashedly, trembling as Aiden noticed something damp against his thighs.

"Nushi-sama…" she murmured with an embarrassed expression. "Haven't you had enough after wrecking Muku's body and the others' for hours? Nushi-sama is such a beast."

She recalled the previous night and blushed as the memories resurfaced.

Aiden's [Camael] regeneration was incredible—yes, even with that power, she was exhausted.

Still, she couldn't deny that the pleasure had been indescribable.

Among them all, the one who lasted the longest was Kotori, who also possessed [Camael], but even she couldn't keep up with him.

"Who makes my Mukuro so beautiful and lascivious?" Aiden whispered softly in her ear.

Mukuro looked at him, even more embarrassed, lightly patting his chest to hide her growing blush.

"Nushi-sama should be gentler with Muku... Muku was the first to faint so many times, and the others saw it!" she protested, burying her face in Aiden's chest.

Aiden couldn't help but smile at Mukuro's adorable reaction.

Even though they had been together for 100 years, his relationship with her and the others remained unchanged.

Mukuro still got embarrassed about things like this, which made her all the more endearing in his eyes.

"N-Nushi-sama…" Mukuro murmured as she felt Aiden lift her with telekinesis, manipulating his Reiryoku to carry her like a princess and head to the bathroom.

"Let's take a bath… I promise it'll just be a bath… I won't do anything…" Aiden said, though his weak excuses were easily dismantled.

Mukuro rolled her eyes, clearly aware of his intentions.

After all, she could feel something pressing against her rear.

Upon entering the bathroom, Mukuro ended up creating a barrier to avoid waking the other girls, anticipating that the "bath" wouldn't be as innocent as Aiden promised.

"Oh~~~♡ Oh~ ♡~ Yes, Nushi-sama~♡! Muku.... Can't take it anymore~Oh~♡"

"I'm cumming~♡!!!"

[*]

Later, immersed in the hot water of the bathtub, Mukuro gazed at him with a pensive expression.

"Nushi-sama is a beast. Bad! Bad!" she scolded, giving him a small tap on the chest.

"Hahaha…" Aiden merely laughed nonchalantly.

...

"What will we do from now on?" Mukuro asked, changing the topic.

"Yesterday, you mentioned seeking contact with someone from the supernatural world to create false identities and buy a large property."

Aiden nodded, closing his eyes as he enjoyed the bath.

"Yes… but I'm not sure who to build relationships with. Gods don't interest me much; they're too troublesome. Besides, I'd have to expose my identity for them to take me seriously, and I doubt they'd be interested in the things I want to develop."

He had no issue revealing his identity… but he simply didn't want a relationship to start off on that note.

"What about Heaven, Grigori, or the demons?" Mukuro suggested.

"If I had to choose between those three, I suppose it would be Grigori or the demons… I have nothing against Heaven, but their resources don't interest me."

Aiden thought of Heaven's subordinate church, corrupt and dark.

While demons and fallen angels also had their shady sides, at least they didn't pretend to be something they weren't.

"Nushi-sama, yesterday you mentioned being interested in the [Sacred Gears] researched by the leader of the fallen angels and the demons' [Evil Pieces], right?" Mukuro observed him curiously.

"Yes," Aiden nodded. "After reading about them on Supernatural.net, I found those things interesting. Since we'll be living in this world, I thought about allying with one of those factions, creating my own group, and strengthening ourselves."

He continued explaining:

"I'm interested in the [Evil Piece] system because, with my [Analyze] magic, I could study them and perhaps create a version for my race, the spirits. That way, I could reincarnate others as spirits or semi-spirits, whether they're from this world or others."

"Will you call them [Spirit Pieces]?" Mukuro asked, intrigued.

"For now, yes. I also want to find the world where the [Falna] originates so I can offer it to my future subordinates."

Aiden envisioned a powerful group that combined [Spirit Pieces], [Sacred Gears], [Falna], and the magical abilities he had developed over the years.

Though he knew it would take time, he considered an initial alliance as the first step.

"And as for the [Sacred Gears], I want to research them to create artificial versions. With my [Blacksmith] and [Mystery] development abilities, it shouldn't be impossible, especially with the materials from Elicia that I brought along."

Mukuro nodded, understanding his plan.

"So, Nushi-sama wants to use those tools to strengthen your future allies and ensure their loyalty. With modified [Evil Pieces] and artificial [Sacred Gears], you could form a strong group… but you'll need help from other factions at the start, right?"

"Yes. Normally, I could steal information about these things with [Rasiel], but they're hidden. I suppose it's high-level magic or something similar that interferes with information-gathering abilities… It would work in other worlds, but here it's useless against highly protected secrets like these," Aiden explained.

While [Rasiel] remained useful as an information source in this world, the secrets protected by factions and never revealed to the public remained inaccessible.

For instance, although he knew of the artificial [Sacred Gears] created by Azazel, he had no idea how they were manufactured, as they were shielded with numerous barriers.

The same was true for Ajuka Beelzebub and his [Evil Pieces].

"I see... So, Nushi-sama, will it be the fallen or the demons?" Mukuro asked.

Aiden remained silent for a few moments, reflecting. Finally, he responded:

"I suppose the demons first... There's a house among the 72 pillars of the Underworld that meets the requirements I'm looking for. They might also be interested in having a powerful ally. Additionally, the fully immersive virtual reality technology from my past life could be developed and sold with their workforce. They don't have a Maou either, so my power could be useful to them."

"A house with great influence among the 72 pillars... Gremory doesn't have a Maou because Sirzechs Gremory took the name Lucifer a while ago, becoming the strongest demon and the symbol of power among the Maou. But they still have his support. There are many clans among the 72 pillars, but the most influential house, aside from those that have produced a Maou, is the Phenex house, right?" Mukuro reflected.

"Yes, that house fits what I'm looking for. It's the richest in the Underworld and has great influence in both the supernatural and human worlds," Aiden replied.

"Additionally, they have enough workforce to produce the NerveGear from my past life. I could even improve the headset with magic and make time run slower in the virtual world. That would be useful for both worlds."

As Aiden and Mukuro continued debating their plans, the bathroom door suddenly opened.

A girl with loose, messy black hair observed them with a gaze that mixed amusement and boldness.

"Ara… so early in the morning, and Danna-sama is already so active…" Kurumi commented as she casually walked in.

Without any concern, she quickly showered before joining them in the bathtub.

Hugging Aiden, she asked:

"What were you talking about so seriously?"

Mukuro and Aiden explained their plans, to which Kurumi nodded thoughtfully.

"I see... But didn't the Phenex have an arranged marriage with the Gremory? Wouldn't that connect them indirectly to Sirzechs Lucifer?"

Aiden shrugged indifferently.

"It doesn't matter. They have the workforce and influence I need to produce and sell the NerveGear. I avoided seeking a house directly connected to the Maou because I don't want to get too involved in Underworld politics… it's troublesome. I have no interest in those old men who rule alongside the Maou."

"Anyway," Aiden continued, "when we create our false identities, we'll need surnames. Do you want a unique surname, or would you prefer to use mine, 'Avalon'?"

"Of course, Nushi-sama's."

"Of course, yours."

Mukuro and Kurumi responded in unison.

"But isn't it strange…? If you have my surname before we're married, won't it look a little odd?" Aiden asked, raising an eyebrow.

Though they spent 100 years in Elicia, they never held a wedding or anything similar; they simply consider themselves married.

"You're right… Well, we'll figure that out when it's time to create the identities. For now, let's focus on what we need to do," Kurumi replied while caressing Aiden's tool, which seemed overly enthusiastic.

Mukuro sighed, resigned, as she placed a barrier around the bathroom to prevent the sounds from escaping.

"Muku hopes she doesn't pass out again…" she murmured.

"Please, be gentle with me," Aiden said, flawlessly pretending to be shy, blushing like a teenager.

He knew they enjoyed those kinds of games, and with his handsome appearance, he flipped the switch for both of them.

...

"Nnyaaa~♡ my breasts~♡, my breasts~♡! Ah!"

"Kurumi, your ruined face is so beautiful!"

"Nooooo~♡ don't look at me! Nyaa~♡ something's coming, it feels so good~~~♡! I'm cumming.....♡!"

The bathroom was soon filled with moans, gasps and bustles, prolonging the fun for quite a while.

[***]

End of the chapter.

(•_•)

A/N:

I won't write R-18 scenes. At most, I'll include moans and then cut to another scene or something similar.

It's not that I dislike writing that kind of content, but I don't particularly enjoy it either.

Besides, there's the issue with the translator I use—ChatGPT doesn't allow me to translate material like that.

Anyway, I didn't plan to write those scenes, so I'll stick to adding some moans and then cutting away.

Honestly, I don't even know how I managed to find time to write this chapter.

Seriously, I have so many things to do in my life, although, thinking about it, this does mean my writing speed is improving…

So hey, at least something good came out of it!

Anyway, I wanted to take this opportunity to thank you all.

This book already has over 3,000 favorites and more than 900 power stones, so I decided to give you a little gift as a token of my gratitude.

But hey, don't be like me; take care of your real-life responsibilities! I have a ton of things to do right now… but oh well, that doesn't matter anymore.

Alright, here are some extra details:

In the next mini-arc, there will be a few differences from the original work, and I might include myths that weren't developed in DxD, such as Yamata no Orochi, Tamamo no Mae, and the Kegare.

As for the idea of seeking out the Phenex house as a partner, I'm doing it to involve the protagonist with the original characters.

Don't worry, Aiden won't be there to save Rias' skin—that's Issei's job.

Just to clarify: Issei won't be humiliated in this fanfic, and his harem won't be stolen (although some members might). However, he won't be unhappy either.

By the way, here's an extra note: the [Analyze] magic that Aiden will use to examine the [Sacred Gear] and [Evil Pieces] wasn't something I made up. It actually exists in Isekai wa Smartphone to Tomo ni.

Anyway…

Thank you for reading my story~!
