Reincarnated in DXD(rewrite)

Advanced Gigai Development and New Ventures

Two years later, a lot changed. My training has intensified, with a focus on mastering advanced techniques in alchemy, soul manipulation, and spiritual evolution. My night classes, guided by the expertise of Van Hohenheim, Kisuke Urahara, and Kirio Hikifune, have been instrumental in expanding my understanding of complex magical theories and practical applications. Through countless hours of study and experimentation under their guidance, I successfully pioneered the creation of two groundbreaking Gigai models. These Gigai represent a fusion of ancient alchemical principles, modern magical technology, and deep knowledge of soul and spirit particle dynamics, setting a new standard in the field of artificial bodies and spiritual evolution.

New Gigai Models

Enlightened Human GigaiThis Gigai allows a human soul to evolve into an enlightened human, similar to those seen in "That Time I Got Reincarnated as a Slime." Enlightened humans possess exceptional tolerance for Magicules, large mana reserves, high magical precision, and extended lifespans. Their demi-spiritual nature enhances both physical and mental capabilities.However, using a pure enlightened human Gigai would overwhelm an ordinary human soul, leading to soul damage or complete energy depletion. To solve this, I designed the Gigai to allow gradual synchronization, enabling the soul to adapt and fully harness the enlightened human form over time.

Archdaemon Gigai is Modeled after Archdaemons from the same world, this Gigai transforms the user into a devil-based Archdaemon hybrid. Archdaemons are immensely powerful and possess superior magical resistance.Similar to the human-based model, this Gigai was designed with a devil base to allow a smooth transition and synchronization process, ensuring that the soul can safely integrate with the new body.

Beyond the creation of Gigai, I also developed numerous Devi-beasts, inspired by Pokémon from various regions, blending unique magical attributes into their designs. The preserve I established spans a vast area, carefully crafted to simulate diverse ecosystems, ensuring that each Devi-beast thrives in its ideal environment. From forest zones and lakes to arid deserts and icy plains, the preserve offers an immersive experience for visitors, making it a favorite destination for young devil children who love interacting with the magical creatures.

While the preserve does not house legendary Devi-beasts, it boasts a wide variety of species, each with distinct abilities and traits derived from different Pokémon regions. Regular tours and special events, such as feeding sessions and magic-infused games, keep visitors engaged. Additionally, I've introduced educational programs that teach young devils about magical ecology, alchemy, and the ethical treatment of magical creatures. The preserve has become not only a popular recreational area but also an important center for magical education and research.

This venture turned out to be highly profitable, with the entrance fees not only covering operational costs but also generating significant revenue. The preserve became self-sustaining within months, drawing visitors from neighboring territories eager to see and interact with the Devi-beasts. Thanks to the preserve's immense popularity, I no longer need to rely on my father for funds—a task that always required careful maneuvering to avoid my mother's meticulous scrutiny of financial matters. Despite the venture's success, my father imposed a 20% share of the profits, justifying it as a territorial tax. However, I strongly suspect that my mother, with her unrivaled business instincts and ability to negotiate even the most one-sided deals to her advantage, was the true architect behind this arrangement. I couldn't help but marvel at her cunning, knowing full well that no profitable endeavor within her reach would ever escape her grasp entirely.

Using my newfound wealth, I founded Smiling Devil Industries, which focuses on producing and marketing high-end alcoholic beverages:

Devil SpiceA premium vodka crafted from the rare honey of specially bred Devi-beasts, distilled through a sophisticated magical process involving precisely inscribed runes and intricate magic formulas. Each batch undergoes multiple stages of purification using unique magic circles, ensuring a perfect blend of potency and flavor. This meticulous process results in a rich, smooth vodka with a complex flavor profile and a warming finish, making it highly sought after by connoisseurs. Early tasters have praised its distinct taste, noting hints of exotic spices and floral undertones, solidifying its reputation as a luxurious and elite drink.Divine BrightA sophisticated wine crafted specifically for fallen angels and, eventually, angels, offering a blend of elegance and purity. Made from specially cultivated and purified grapes grown in a magically enriched vineyard, the fermentation process involves continuous infusion with pure spirit particles, enhancing both flavor and potency. The resulting wine is renowned for its smooth texture, complex bouquet, and radiant golden hue. Tasting notes reveal a delicate balance of sweetness and acidity, with subtle hints of divine essence that linger on the palate. It has quickly earned a reputation as one of the finest wines devils have ever savored, becoming a coveted item among high society and elite circles.

The potential profitability of these products attracted eager investors, my parents, brother, and his wife—who were quick to secure a share in the business. Despite my initial annoyance, I recognized the strategic value of their involvement, as their influence and networks could significantly boost the company's market presence. "Bunch of money grubbers," I thought, though I couldn't deny that having them on board would open doors to lucrative opportunities and partnerships.

I also made significant progress in data materialization by expanding upon the Archive spell from the Fairy Tail world, which converts information into magical data. This development began as a simple concept of digitizing knowledge and rapidly evolved into something far greater. I envisioned creating an internet-like network powered entirely by magical data, encoded into infons—particles unaffected by time and space—to enable instantaneous and seamless information transfer regardless of distance or external disruptions.

The core idea was to eliminate traditional latency and interference issues by utilizing infons' unique properties. I theorized that this method could surpass any known communication system, even rivaling the sacred gear transmission network used by Heaven. Extensive experimentation and creating crucial mathematical models and algorithmic encoding techniques, allowed me to refine this network further. Ultimately, this led to the creation of a highly advanced, secure, and autonomous information grid capable of supporting real-time data exchange across multiple dimensions.

The culmination of this effort was the creation of an avatar to oversee and manage the groundbreaking network leap in digital magic and life creation. This avatar marked my first attempt at generating a fully sentient digital lifeform, something I had never done outside of my Pocket dimension. This is the first time that I have been drained of so much mana since that catastrophic training accident that once drained all my mana. The result was an endearing, small, white creature with large, expressive eyes and short limbs, resembling Calumon from Digimon. Upon creation, it immediately flew into my hands, nestled comfortably, and fell asleep, emitting a soft glow.

I named him Kei, symbolizing the crucial role he would play in maintaining and upgrading the Ethernet. Over time, Kei revealed himself to be far more than just a simple network manager—his high intelligence and innate adaptability allowed him to rapidly acquire new knowledge, develop a distinct personality, and contribute to advanced system enhancements. Despite his technical prowess, Kei exhibits a childlike nature when not performing his duties. Initially shy and hesitant to venture far from my side, he gradually grew comfortable around the household, forming bonds with everyone. Kei particularly enjoys playing in the garden but remains wary of the women in the family, who are often captivated by his adorable appearance and eager to pamper him.

Kei's primary role involves constant oversight of data transmission, ensuring the stability and security of the network while preventing any breaches or disruptions. His ability to process and relay information across dimensions with zero latency makes him indispensable. When not actively engaged in monitoring or optimization tasks, Kei likes to explore the estate. He can frequently be seen hovering mid-air or perched atop high shelves, quietly observing his surroundings with an air of curiosity.

In my lab, I constructed a specialized training room inspired by the gravity chamber from Dragon Ball, designed to push the limits of both physical and magical endurance. This room not only enhances gravity but also exerts immense atmospheric pressure, creating an environment where even devils struggle to move freely. Its primary purpose is to refine my mana control and ensure that I can always maintain mana skin—a protective coating of mana that shields the user from external forces, a technique commonly used by Magic Knights in Black Clover.

The room's gravity settings can be adjusted in incremental levels, starting from double normal gravity up to levels that would crush an unprepared warrior. To enhance the challenge, I integrated various environmental hazards, such as sudden temperature changes and mana-disrupting fields, forcing me to adapt and perfect my mana flow under extreme conditions.

Additionally, advanced battle dolls inhabit the room, programmed with combat strategies and armed with weapons forged from anti-gravitatis metal, a unique alloy I created through alchemical synthesis and knowledge of exotic elements from multiple worlds. This metal is unaffected by gravity manipulation, ensuring that the battle dolls remain effective opponents regardless of the room's settings. Each doll is equipped with self-learning algorithms, allowing them to adapt to my fighting style and tactics, providing a dynamic and ever-evolving combat experience.

The room features multiple difficulty levels, with each successive level escalating the gravitational pull, atmospheric pressure, and the number of battle dolls that engage in increasingly complex combat scenarios. At each level, new environmental hazards are introduced, such as fluctuating temperatures, sudden bursts of wind, and magical interference fields that disrupt mana flow, demanding quick adaptation and heightened awareness.

Currently, I am stuck at level 2. This level requires not only physical endurance but also flawless execution of mana control techniques to maintain my mana skin and avoid severe strain from the overwhelming gravity and relentless attacks of the battle dolls. Despite the grueling nature of this training, I have already observed significant improvements in my mana efficiency, reaction speed, physical resilience, and strategic thinking. Every session pushes my limits, sharpening my combat instincts and refining my ability to wield magic under extreme conditions.

Looking ahead, I plan to upgrade the room further by incorporating additional advanced battle scenarios, such as multi-target engagements and simulated magical storms, ensuring that my growth remains continuous and challenging.

One day, while monitoring events in Kuoh Town through the Ethernet, I noticed a dire situation unfolding between two forbidden lovers, whose imminent demise was approaching rapidly. Their plight resonated deeply with me—a tragic tale of love on the brink of being extinguished by forces beyond their control. I could not, in good conscience, allow this to happen. Driven by a sense of duty as a guardian of love and life, I made an immediate decision to intervene. After all, my role isn't to exploit people as mere experiments but to protect and offer them a new path.

Without hesitation, I activated a high-level teleportation Kido, transporting myself directly to their location. Accompanying me were Kei and two of my most advanced Gigai models, which I had specifically designed for not for this exact situation.

Kuoh Town

In a grand mansion, illuminated only by the dim glow of the moonlight filtering through the windows, a woman with long grayish hair lay sprawled on the cold marble floor, blood pooling around her fragile form. Her breaths were shallow, each one more labored than the last, as the searing pain in her chest became unbearable. As she began to slip into unconsciousness, her mind was overwhelmed by a torrent of emotions—heartbreak, regret, and the unbearable weight of unfinished dreams. She lamented the choices that had brought her to this moment, wondering if things could have been different.

With her vision fading and the encroaching darkness threatening to consume her entirely, a sudden flash of light filled the room. It was unlike anything she had ever seen—pure, radiant, and warm, as though it carried with it a promise of hope. For a brief moment, she felt the pain ebb away, replaced by a sense of calm. Then, everything went black, and silence enveloped the grand mansion once more.

Moments later, both she and a man with long black hair regained consciousness. They found themselves in the same mansion, alive but bewildered.

"Where am I? Did I die? Is this heaven?" the man asked as he spotted the woman beside him.

"Masaomi?" she whispered, tears streaming down her face as she rushed into his arms.

Their reunion was interrupted by a voice. "You both died," I said, standing above them with Kei perched beside me.

Shocked, they asked who I was and what I wanted. I calmly explained that the barrier I had meticulously placed around the mansion was a unique spell designed to suspend them in limbo, effectively preventing their souls from passing on to the afterlife. This spell was no ordinary barrier; it operated on a delicate balance of spiritual energy and time manipulation, ensuring that while their bodies appeared lifeless, their souls remained tethered to this plane. Without it, they would have already crossed over, beyond the reach of any intervention. My purpose, however, wasn't merely to delay their fate but to offer them something more—a second chance at life, albeit under very specific conditions.

"I didn't do this just to talk," I added, my voice calm but firm. "I have a job offer for you. If you accept, you will be granted a new lease on life, but it comes with a price. You must sever all ties with your past lives—family, friends, everything you once knew. In exchange, you will follow my instructions, and in return, you will not only live again but have the opportunity to create a future of your own design, perhaps even raise a family, free from the burdens that led you here."

Despite initial hesitation, they agreed after a moment of silent contemplation. Masaomi, with a determined gaze, took the human-based Enlightened Human Gigai, knowing that it symbolized a new beginning beyond his mortal limitations. Cleria, though still conflicted about severing ties with her past, accepted the devil-based Archdaemon Gigai with quiet resolve, understanding that this was the only way to remain by Masaomi's side.

I carefully handed them the Gigai models, each one crafted with precision and imbued with a unique aura tailored to their respective natures. "Once you bond with these bodies, you will gain new powers and a second chance at life. Remember, this isn't just about survival—it's about building a future where you can truly be free."

As they prepared to bond with the Gigai, they asked, "Does it really matter at this point?"

I smiled warmly, offering a reassuring nod. "Not really. By the way, my name is Maxius Gremory, and I'll be your new boss. I know this might feel overwhelming but trust me—this is a new beginning for both of you. From here on, we're forging a future that's entirely your own. You'll have freedom, power, and the chance to build something far greater than what was lost."
