A week later, trouble began to brew in the regions that had chosen not to ally with us. While these disturbances affected all territories, they were swiftly managed by those aligned with the Federation. Most threats were minor, though some were significant, yet they were dealt with efficiently by our allies. On Sado Island, however, I found myself sidelined, as my companions and subordinates handled the challenges with remarkable ease.

  Strange portals of various colors began to materialize from the unknown, each one a harbinger of chaos. Among them, four stood out as particularly deadly: gray, purple, red, and black. The black portal, in particular, was the most menacing, appearing in regions that had rejected the Federation’s aid. I had encountered some of these colorful anomalies, but they were swiftly dealt with by my demon subordinates and the Islanders.

  Whenever a threat became too formidable, the Islanders would call upon me, praying for strength or summoning me through their thoughts. This unique connection was one of the gifts I had received upon my ascension; my followers could draw upon my power simply by invoking my name, whether through silent contemplation or vocal prayer. It was a bond that transcended the ordinary, a testament to the faith they placed in me.

  In Nara City, ruled by Mei Daisuke, the people faced a dire threat from the gray portal. It was a challenge that had left Mei battered and on the brink of death, with no aid from the remnants of the holy church. Just when hope seemed lost, Beleviamoth arrived, effortlessly vanquishing the newly ascended True Demon Lord and an Elder God. With a wave of her hand, she restored the city to its former glory, an astonishing feat that left Mei speechless. Revived by Beleviamoth’s aura, Mei, in her moment of desperation, relinquished her pride and ego, embracing the Federation’s changes and welcoming magic technology into her city.

  Meanwhile, in Kyoto City, Takuya Fumiko struggled against the purple gate, which was controlled by the Shadow King and a celestial warlord. Takuya and his people found themselves overwhelmed, unable to seal the portal or defeat the high-ranking supernaturals in charge. Even the remnants of the holy church could not provide sufficient aid. Just when all seemed lost, help arrived from Sado Island in the form of one of my Islanders, who vanquished the supernaturals and restored the city and its people to full power. Takuya, left in awe, came to terms with the necessity of alliance and accepted our offer of partnership.

  In Naha City, ruled by Natsumi Yamada, the situation was equally dire. The red gate, controlled by a Dragon Sovereign and a Holy Tribunal Angel clad in gleaming golden armor, threatened to bring utter destruction. With no support from the empire or the remnants of the holy church, Natsumi and her warriors struggled to hold their ground. Just as despair threatened to consume them, Beliamoth arrived, saving the city and restoring its people to their full strength. In the aftermath, Naha City recognized the value of the Federation and allied themselves with us, embracing magic technology.

  Yokohama City, under the rule of Shinichi Junko, faced its own crisis with the black gate, controlled by a Mischief Deity whose aura level far exceeded that of Shinichi and his warriors. The city teetered on the brink of destruction, receiving no aid from the empire or the remnants of the holy church. In a desperate bid for survival, I joined a small expedition from Sado Island to confront the Mischief Deity. Together, we defeated the malevolent force and restored Yokohama City to its former glory.

  However, our celebration was abruptly interrupted when all the colorful portals merged into one, reappearing in Yokohama City. The merging of the gates severed all communication with the outside world, engulfing the entire city in a swirling vortex that transported us to a realm of abominable chaos.

  In this new dimension, we found ourselves facing a demon overlord whose aura was so intimidating that it sent shivers through Shinichi and the citizens of Yokohama. Yet, my subordinates and I stood resolute, undaunted by the megaversal power radiating from the demon. I stepped forward to challenge him, feeling the weight of my own desire to prove myself. My subordinates had been claiming glory for too long, and now it was my turn to shine. The time had come to show what I was truly capable of.

  The demon overlord loomed before us, a towering figure whose size dwarfed us all. Yet, as the saying goes, the bigger they are, the harder they fall. Our eyes locked in a fierce gaze, and in an instant, we charged at each other with a speed that left the citizens of Yokohama in awe. They had never witnessed such velocity, a blur of motion that defied comprehension—except for my subordinates, who watched with knowing smiles.

  As we clashed, the sheer force of our movements sent tremors through the very fabric of the dimension. This was the demon overlord's domain, the realm he governed, and the orchestrator of the colorful gateways that had wreaked havoc across the regions. Our fists collided with a thunderous impact, sending shockwaves rippling through a dimension that was tens of billions of times larger than a multiverse and a metaverse combined. With each strike, we peeled back layers of the cosmology that governed the megaverse, revealing the intricate tapestry of existence.

  To the demon overlord's astonishment, I matched his speed and strength, all while keeping the seal on my forehead intact. Time became irrelevant as we battled, each moment stretching into eternity. I gauged his abilities, assessing the worth of this fight, and after a prolonged exchange, I decided it was time to end it once and for all.

  In a split second, I broke the seal on my forehead, unleashing a surge of power that enveloped me. With newfound strength, I launched a final, devastating blow that brought the demon overlord to his knees. In that moment, I became one with the energy that flowed through me, my rankings evolving alongside the defeat of my foe.

  Once the demon overlord lay vanquished, I resealed the mark on my forehead and undid the chaos he had wrought, restoring Yokohama City to its original state. My subordinates, ever vigilant, had already begun their work, healing the injured, raising the dead, and revitalizing the auras of everyone present, including Shinichi.

  Overwhelmed with gratitude, Shinichi fell to his knees, tears streaming down his face as he struggled to find the words to express his appreciation for our timely intervention. I humbly urged him to rise, offering him a choice once more: to join the Federation. Without hesitation, he accepted, embracing the promise of magic technology and the alliance that would strengthen us all.

  In that moment, a new chapter began for Yokohama City, one filled with hope and the potential for greatness as we united against the challenges that lay ahead.

  Returning to Sado Island, I was greeted by the familiar sights and sounds of a bustling community, vibrant with life and activity. Yet, amidst the orderly chaos, I felt a weight on my shoulders. I needed to personally inform the Federation of our recent success, and I knew Kokoro would be pleased to hear that we had united all regions as one.

  As the days passed, magic technology spread like wildfire across every region, including Nagoya City, Fukuoka City, and Kanazawa City. These cities, which had once hesitated to embrace the new advancements, were now fully on board, integrating magic tech into their systems alongside their traditional practices. It was a remarkable transformation, a testament to the power of unity.

  However, the joy of progress was tinged with bittersweet sorrow. I received word of Kokoro's ascension to the ancestral plane, a moment I had missed. Her daughter, Maria, now stood as the successor, tasked with leading the Federation. Maria confided in me her fears and uncertainties, seeking my guidance more often than not. I could see the weight of leadership pressing down on her, and despite her trusted councilors, she felt the Federation was secretly fracturing under the strain of power struggles. I vowed to stand by her side, to guide her through the tumultuous waters ahead.

  Delilah and I were nurturing a blossoming romance, our connection deepening with each passing day. My ranking status continued to improve, a reflection of our collective efforts and the unity we had forged. Yet, even amidst this newfound stability, I sensed an undercurrent of tension, a feeling that something unexpected was on the horizon.

  Just seven months after my ascension to demon overlord, everything had been running smoothly across the regions. But then, unexpected visitors arrived at our doorstep—warriors from the Katsuragi Victory Empire. I had just concluded a council meeting with my people when a messenger burst in, delivering the news that the empire's warriors were here to see me at the emperor's behest.

  "Whoa! Took them long enough," I muttered to myself, a mix of curiosity and apprehension swirling within me. "I always expected the empire to show up sooner. Perhaps they see the unity of all regions under the Federation as a challenge to their authority."

  Stepping out to greet the visitors, I was accompanied by a few of my council members. There, I found six warriors standing before me, their presence commanding and powerful, though not nearly as formidable as my subordinates or the Islanders. They introduced themselves with a sense of formality, then relayed the message from the empire: my presence was requested.

  Sakura Kato, as a Knight Commander, is a seasoned leader and warrior who commands battalions of knights across the vast territories of the Katsuragi (Victory Empire). Her tier 5 rank places her among the elite knights, whose abilities extend across entire galaxies. She is not only a skilled tactician but also an immensely powerful combatant, capable of facing galactic-level threats with her enhanced physical and magical prowess.

  Born of a union between a powerful Harpy and a human warrior, Sakura Kato inherited the best of both worlds. From her Harpy lineage, she gained the ability to fly, extraordinary agility, and enhanced senses. Her human heritage provided her with tactical intelligence, adaptability, and the ability to wield both magic and advanced weaponry. This unique combination of traits made her a formidable warrior from a young age.

  Sakura's rise through the ranks was rapid, as her natural talents, coupled with rigorous training, quickly set her apart from her peers. She displayed remarkable leadership skills, earning the respect of those she commanded. Her ability to stay calm under pressure and make quick, decisive moves in the heat of battle allowed her to lead her knights to victory against some of the most dangerous threats the empire had ever faced.

  Throughout her 1,500 years of life, Sakura has fought in numerous wars across the galaxy, defending her empire from cosmic invaders, monstrous entities, and rival factions. Her harpy abilities give her a distinct advantage in aerial combat, while her strategic mind makes her a master of battlefield coordination. She is often called upon to lead high-stakes missions where failure is not an option.

  Despite her harsh upbringing, Sakura is known for her compassion towards those under her command. She believes that true strength lies in unity and that every knight, no matter their rank, plays a crucial role in the success of the empire. Her leadership style is firm but fair, earning her loyalty and admiration from her battalions.

  Sakura's dedication to the empire is unwavering, and she has little time for a personal life outside of her duties. However, she values the friendships she has formed with fellow knights and hunters, seeing them as her extended family. While she may seem distant to those who don't know her well, those who have fought alongside her understand her deep commitment to protecting the empire and its people.

  In battle, Sakura is a fearsome sight, her harpy wings giving her unparalleled mobility as she rains down magical attacks from above. Her signature weapon, a glaive infused with both celestial and arcane power, has cut down countless enemies and is a symbol of her status as one of the most powerful commanders in the Katsuragi (Victory Empire).

  Akiko Daiki is an AB Rank Huntress, skilled in taking on threats that can devastate entire solar systems. Her presence is often called upon when civilizations face impending cataclysms that require a powerful and capable defender. Akiko's abilities as a hybrid of human and mermaid heritage give her unique advantages in battle, particularly in aquatic environments, but she is just as formidable on land.

  Born to a human father and a mermaid mother, Akiko grew up in both worlds, mastering the skills of a huntress from a young age. Her mermaid blood grants her extraordinary strength, agility, and the ability to breathe and thrive underwater, while her human side provides her with versatility and adaptability in various environments. She spent her early years learning the ways of the ocean, training in combat, and honing her magical abilities under the guidance of her mother and other sea-dwelling mentors.

  Despite her aquatic origins, Akiko was drawn to the larger world and the challenges it presented. At the age of twenty, she left her underwater home to join the ranks of the Victory Empire's elite huntresses, determined to protect not just the oceans but the entire empire. Her natural talent and dedication quickly earned her a place among the AB Rank hunters, where she became known for her ability to neutralize solar system-level threats.

  Akiko's prowess in battle is matched by her strong sense of duty and loyalty to her fellow hunters and knights. She often leads missions in dangerous waters, where her unique abilities are indispensable, but she is equally skilled on land, where she can use her water-based magic to manipulate her environment and defeat powerful foes. She wields a trident imbued with oceanic energy, which she can use to channel both offensive and defensive magic.

  Despite her relatively young age compared to many of the empire's seasoned hunters, Akiko has earned a reputation as a dependable and fierce protector. Her calm demeanor and strategic mind make her a valuable asset in any battle, and she has become a mentor to younger hunters who look up to her as a role model.

  Outside of combat, Akiko is known for her love of the ocean and its creatures. She often returns to her underwater home to visit her mermaid family and recharge her energy. Her deep connection to the sea gives her a sense of peace and balance that she carries with her, even in the most chaotic battles.

  Akiko's journey is far from over, and she remains committed to defending the Victory Empire from any threat, no matter how great. With her unique heritage, skills, and unwavering determination, she stands as one of the empire's most capable and trusted huntresses.

  Chisato Jiro is an A Rank Huntress, renowned for her ability to combat threats that pose a danger to entire planets. Her dwarven heritage grants her exceptional physical strength, resilience, and a deep connection to the earth, making her a formidable guardian of planetary safety. Chisato is highly respected within the Victory Empire for her heroic deeds and her unwavering commitment to protecting worlds from catastrophic dangers.
