Reincarnated in DXD(rewrite)

A light green hexagonal barrier appeared around us, shimmering with an intricate weave of magic that pulsed rhythmically as it absorbed the incoming attack. The gathered magic concentrated in a single area, creating a focal point where the force was momentarily held, neutralized, and then redirected outward in a powerful surge that dispersed the attack harmlessly. The sheer brilliance of the barrier illuminated the surroundings, casting dancing reflections of green light across the ground and nearby trees, leaving a faint shimmer in the air as it gradually dissipated into nothingness.

When everything settled, the barrier vanished, revealing Maxius and Katsumi standing in its place. Katsumi's expression was calm, but there was a hint of tension in her stance, as if she was ready to spring into action at any moment.

"Well, since you want to fight, I'll quote one of my favorite people… let's dance," Maxius said, his tone carrying a mix of amusement and resolve. Casually, he removed his lab coat and shirt, revealing a physique honed through relentless training—his muscles were well-defined, exuding strength far beyond what was typical for someone his age. His smooth, unblemished skin contrasted with the intensity in his eyes, which held the steely determination of a seasoned warrior.

The onlookers couldn't help but sense the shift in the atmosphere. Maxius's confident smile was the calm before the storm, a silent declaration that he was ready to take on any challenge without hesitation. Every movement he made exuded control, precision, and unwavering focus, as though he had already anticipated the outcome of the impending battle.

In an instant, he vanished from sight, reappearing beside the man on the far-right with blinding speed. Maxius delivered a devastating punch to the man's face, one that carried the overwhelming strength of a devil born into combat. This was no mere punch—Maxius's fist landed with bone-crushing force, sending shockwaves through the air as the man was hurled backward like a ragdoll.

Maxius's strength wasn't ordinary even by devil standards. His body had been forged through relentless and brutal training. He had endured punishing sessions with Sairaorg, whose mastery of Hasshoken enabled him to generate powerful shockwaves with every strike. Maxius had also survived the harsh tutelage of his sword masters, who had pushed his body and mind to their absolute limits, sculpting him into a warrior who could endure any hardship.

The man Maxius struck crashed into the ground ten yards away, rendered unconscious before he even hit the dirt. Without missing a beat, Maxius pivoted toward the next two attackers, dispatching them with equally devastating precision. His movements were a blur—fluid, efficient, and unstoppable. Each blow landed with pinpoint accuracy, incapacitating his opponents in mere moments.

The sheer speed and overwhelming power Maxius demonstrated left no room for counterattacks, turning the skirmish into a brutally one-sided spectacle. In less than fifteen seconds, three combatants lay defeated, scattered across the battlefield. Only one remained—a brown-haired man standing frozen in place, his wide-eyed expression a mixture of shock and growing fear as he struggled to process the effortless destruction Maxius had wrought.

The man Maxius struck was hurled into the air and landed ten yards away, knocked out cold. Within seconds, two more of his companions followed suit. The speed and precision with which Maxius attacked left no room for retaliation. The only one left standing was a brown-haired man whose eyes widened in shock. All of this had happened within fifteen seconds.

Maxius returned to Katsumi's side, wearing a look of disappointment. "Man, you guys are weak. I didn't even break a sweat."

The brown-haired man, Isamu Shinra, clenched his fists in rage, his knuckles turning white as his entire body trembled with barely-contained fury. His eyes burned with an intense fire, and a dangerous, crackling aura flared around him, distorting the air with raw energy. Isamu had been expelled from his prestigious clan due to the fearsome Sacred Gear he was born with—Lyca Chimeras, a powerful relic based on the monstrous Chimera of Greek mythology. This unique Sacred Gear granted him the terrifying ability to transform parts of his body into feral, enhanced animal forms, each imbued with magic and devastating strength.

Haunted by years of resentment and rejection, Isamu had honed his abilities in exile, nurturing a deep hatred for those who had cast him out. His transformations were not just weapons but reflections of his inner turmoil—primal, chaotic, and relentless. Every battle he fought was fueled by a burning desire to prove his strength, to make those who had dismissed him pay for their scorn. And now, facing Maxius, that fury boiled over, manifesting in the wild energy crackling violently around him, threatening to consume everything in its path.

"All right, brat. I'll show you what true strength looks like," Isamu growled. His body began to change. His upper clothing shredded as his frame expanded. Thick hair resembling a gorilla's fur covered his chest, his muscles bulging to three times their original size. His head morphed into that of a lion, complete with a mane of hair as sharp as steel. His lower body took the form of a goat, with flames emanating from his hooves. The transformation was both fearsome and grotesque, his very presence exuding primal power.

Maxius and Katsumi stared in shock at the transformation. The air around Isamu grew heavy with oppressive energy, a clear indication of the power he now wielded.

"Katsumi, go hide somewhere. This one won't be easy," Maxius said, his voice serious. He could feel the intensity of Isamu's power and knew this wouldn't be a simple fight.

"Prepare to die, brat," Isamu roared, his voice echoing ominously.

Maxius disappeared again, reappearing near Isamu in a blur of speed, his fist aimed directly at Isamu's midsection. However, this time, Isamu anticipated the attack. With a guttural roar, he countered with a powerful punch, his fist glowing with golden touki, striking Maxius with enough force to send him hurtling backward. Maxius crashed into the ground with a thunderous impact, creating a massive crater that split the earth beneath him. The resulting shockwaves rippled outward, shaking the nearby trees violently and scattering loose debris in all directions.

Dust and shards of rock filled the air, momentarily obscuring Maxius from view. The sheer power of Isamu's strike was evident in the destruction it left behind, and a tense silence followed as the dust began to settle, broken only by the distant rustling of disturbed foliage.

"Maxius!" Katsumi cried, running toward him.

"Stay back!" Maxius shouted, his voice firm. He didn't want her getting caught up in the fight.

Within the crater, Maxius lay covered in dirt, but otherwise unscathed. A grin of excitement spread across his face. The thrill of battle was evident in his expression.

"What happened to that confidence of yours, little devil?" Isamu taunted, sneering.

"Just a lucky punch. It won't happen again," Maxius replied, smirking.

"Oh, really? Let's test that theory," Isamu sneered, launching another punch. This time, the attack was even more forceful, sending Maxius flying again.

The scene played out repeatedly as Isamu unleashed a relentless flurry of attacks, each blow fueled by his growing frustration and rage. Yet, despite the onslaught, Maxius rose to his feet each time, unscathed and unfazed. His mana skin absorbed every strike, leaving no mark on his body. What truly infuriated Isamu, however, was not Maxius's resilience but the unwavering grin that adorned his face after every fall.

Maxius's grin wasn't one of mockery, but rather of excitement—the thrill of battle coursed through his veins. Each time he stood back up, it was as if he was silently challenging Isamu to try harder, to do better. Isamu's fists trembled with fury, his mind consumed by the maddening thought that no matter how much power he poured into his attacks, he couldn't bring Maxius down. The battle had turned into a test of endurance, one where Isamu was quickly losing ground.

"Damn it! Just die already!" Isamu bellowed, gathering a massive amount of touki into his right fist, which began glowing gold. He appeared at Maxius' side, ready to deliver a finishing blow.

Maxius crossed his arms to block the attack. Though he managed to defend himself, the sheer force sent him crashing into an old shrine, destroying it on impact. The ancient structure crumbled into dust and debris, leaving a cloud of smoke in the air.

"Maxius!"

Katsumi couldn't bear to watch any longer as Maxius continued to endure Isamu's relentless attacks. Determined to help, she swiftly pulled out a talisman, her hands moving with practiced precision. She performed a quick Shinto prayer, her voice steady despite the tension in the air, and with a flick of her wrist, she threw the talisman toward Isamu. The talisman landed squarely on his back, immediately flaring with a brilliant light that illuminated the battlefield.

Magical runes materialized around Isamu, encircling him in a complex binding formation. The runes pulsed with potent energy, radiating a force strong enough to momentarily halt his movements. The air around them shimmered from the power of the seal, casting an ethereal glow as the binding circle tightened its grip on Isamu, holding him in place and buying precious moments for Maxius.

"This is…"

"God of the Eight Banners: Seal of Earth," Katsumi said. Despite the high-level nature of the spell and her minimal preparation, she managed to cast it flawlessly, showcasing her genius. The air shimmered with the power of the seal, holding Isamu in place.

"Impressive, girl, but you're years away from holding me," Isamu growled. With a massive burst of touki, he shattered the seal and turned toward her. "Come with me to the Utsusemi Agency. Together, we can get revenge on the Five Principal Clans."

"No. I'm sorry, but I'll have to decline. I've found a path where I can prove my worth to the clans. I'll stand by Maxius as his queen," Katsumi declared, her voice unwavering.

"You'd defile yourself by becoming a devil? Fine, then die along with him!" Isamu roared, his eyes glowing with rage.

"Hey, house cat. Our fight isn't over yet," Maxius said, emerging from the rubble of the shrine, uninjured and wearing the same cocky smile. Dust and debris fell from his clothes as he walked forward.

"Finally, it looks like all my mana control training has paid off," Maxius mused, his voice carrying a mixture of confidence and amusement. He flexed his fingers, feeling the steady flow of mana enveloping his body like a second skin. Despite Isamu's relentless barrage, Maxius hadn't suffered a single injury, thanks to the perfected mana skin technique he had been honing for years.

Every attack so far had merely tested the resilience of his barrier, each strike serving as proof of his hard-earned mastery. Maxius glanced at his hands briefly, noting how the faint glow of mana shimmered along his arms before fading into invisibility. "He's using brute strength without strategy. Typical," he muttered to himself, a smirk playing at the corners of his mouth.

He shifted his gaze back to Isamu, whose frustration was evident in every labored breath. "You still don't get it, do you? Strength without control is just wild force. And wild force alone will never break me."

Isamu snarled in frustration, his aura flaring wildly around him like a raging inferno. "How dare you!" he roared, his voice reverberating through the air. His eyes burned with unbridled fury, every fiber of his being consumed by anger. With a burst of speed, he charged at Maxius, his movements erratic but fueled by sheer power. Each step left scorch marks on the ground, the flames from his hooves igniting patches of earth and grass.

Maxius remained calm, observing Isamu's approach with a calculating gaze. He could see the lack of control in Isamu's movements, every strike telegraphed by his rage. "You're letting your emotions control you," Maxius muttered under his breath. "That's your first mistake."

This time, when Isamu's fist appeared inches from Maxius' face, Maxius vanished in a blur of speed and reappeared behind him with seamless precision. Without hesitation, he delivered a devastating kick to Isamu's back. The impact was so fierce that it propelled Isamu through the air, crashing violently through five large trees. Each tree splintered and snapped under the force, scattering fragments of wood and leaves across the ground like a storm of debris.

As Isamu tumbled to a stop amidst the wreckage, dust and shattered branches filled the air, creating an almost surreal stillness in the aftermath of the strike. Maxius landed lightly on the ground, his expression unchanging, as though the effort had cost him nothing. he remained composed, exuding an aura of effortless strength.

Katsumi watched in awe, her breath caught in her throat as she tried to process what she had just witnessed. Maxius had sent Isamu flying effortlessly, his strike radiating raw, controlled power. The sheer force of the attack shattered the ground beneath him, sending cracks spiderwebbing outward. It wasn't just strength that impressed her—it was the precision and composure with which Maxius fought. For a moment, she felt a mixture of admiration and pride, realizing just how far Maxius had come in his training. Despite the chaotic battlefield, he remained calm, his every movement deliberate and efficient. The sheer power of his strike left her momentarily speechless, her heart pounding as the reality of their situation sunk in.

Isamu struggled to stand, his breath ragged and uneven, as blood dripped steadily from a gash on his forehead. His injured shoulder hung limp at his side, but his eyes still burned with a mix of defiance and desperation. Despite his battered state, the fire of his determination had not been fully extinguished. Every staggered movement betrayed the toll the battle had taken on his body, yet he refused to fall.

Maxius, now serious, stepped forward with an air of quiet authority. His calm but firm voice carried across the battlefield, cutting through the tension like a blade. His gaze was steady, unwavering, as he prepared to deliver the final lesson of the fight.

"Do you wonder why I never cared about not being born with the Power of Destruction?" Maxius stretched out his right hand, summoning a magic circle. From it emerged Akira, the wakizashi he had received from Rias on his birthday. The blade gleamed ominously in the moonlight.

"It's because I spent years building my own strength, training relentlessly while you and your group wallowed in hatred and anger, blinded by your resentment. Instead of striving to overcome your limitations, you allowed bitterness to consume you, dragging yourselves deeper into a pit of despair. You could have risen above your circumstances, forged your path, and stood tall with pride. But you chose to remain chained by your past, and now, you can only look up at those who surpassed you."

Isamu seethed with rage, his entire body trembling with pent-up fury. "Again with your arrogance! Let's see the strength you're so proud of!" he spat, his voice echoing with unrestrained venom. He raised his hand high, and a violent surge of touki erupted from his core, crackling with raw, destructive energy. Golden flames spiraled around his fist, illuminating the battlefield with an ominous glow. The ground beneath him cracked and burned, unable to withstand the sheer intensity of his power.

"Prepare to die, brat!" he bellowed, his tone filled with murderous intent. In an instant, he vanished from sight, moving at a speed so blinding that he appeared as nothing more than a blur of golden light. His trajectory tore through the air, leaving a burning trail in his wake as he closed in on Maxius with deadly precision.

Maxius closed his eyes, his hand resting on Akira's hilt. "Hey, house cat. Are you ready to die? Because once I draw my blade, it'll be the last thing you ever see." His voice was calm, yet it carried a chilling finality.

Isamu appeared beside Maxius, his fist coated in golden touki, mere inches from Maxius' head.

"It's my win, boy. Now die!"

"One Sword Style: Black Divider," Maxius whispered.

In a flash, Maxius opened his eyes, drew Akira, and unleashed a swift, precise slash. The blade, now gleaming with a dark crimson aura, sliced cleanly through Isamu's arm and continued its arc toward his head. The strike was so fast and fluid that from an observer's perspective, it seemed as if Maxius had moved without effort, the entire motion happening in a blink.

Isamu could only watch in stunned horror as the force of the slash sent shockwaves rippling outward, disturbing the dust and foliage around them in a violent ripple. The nearby trees swayed under the pressure, their leaves rustling as if caught in a sudden windstorm. Time seemed to stretch as his severed arm fell lifelessly to the ground with a dull, echoing thud, followed by a growing pool of dark crimson spreading beneath it. But Maxius's strike had not ended there—the blade had bisected Isamu cleanly down the middle, the two halves of his body collapsing in opposite directions.

For a moment, there was only silence, save for the faint rustle of leaves carried by the wind. The once fierce glow in Isamu's eyes dimmed completely, his expression frozen in disbelief. Blood soaked the ground beneath him, marking the end of his rage-fueled struggle. The finality of death hung heavy in the air, a testament to the overwhelming power Maxius wielded.

The once fierce glow in Isamu's eyes faded into disbelief and despair. His breath came in short, ragged gasps as his body, bisected cleanly by Maxius's blade, began to fall apart. Blood poured freely from the fatal wound, pooling rapidly beneath him as his severed halves collapsed lifelessly to the ground. The sheer force and precision of the strike had not only shattered his will but ended his life in a decisive instant. The battlefield grew eerily silent, the only sound remaining was the faint rustling of leaves carried by the wind, marking the finality of Isamu Shinra's rage-filled existence.

Maxius stood tall amidst the fading tension, his blade resting calmly on his shoulder, its dark crimson energy gradually receding into silence. The air, once heavy with the threat of death, grew lighter as nature seemed to resume its quiet rhythm. With a look of quiet finality, Maxius turned to Katsumi, his expression softening. His reassuring smile, faint but genuine, conveyed the unspoken message—the danger had passed, and they had emerged victorious.

"Let's go home," Maxius said softly, his voice steady but tinged with the weight of both triumph and lingering exhaustion. His expression, though calm, reflected the intensity of the battle they had just endured. The night air felt colder now, a stark contrast to the heat of the fight moments ago, as he turned and began to walk, trusting Katsumi to follow without a word.
