I want to be noblesse in dxd

As Cerberus roared, its three heads snapping and snarling, Rias and Akeno took to the air, their expressions hardening.

Hovering above the battlefield, they exuded a powerful aura of seriousness and synergy, their movements perfectly synchronized as they prepared to face the formidable beast.

Rias extended her hand, gathering a crimson orb of energy, her Power of Destruction radiating a dangerous glow.

Beside her, Akeno summoned her elemental power, lightning crackling around her fingertips. The air grew thick with anticipation as the two prepared to strike.

"Cerberus is no ordinary opponent," Rias said, her voice steady. "We need to stay coordinated."

"Yes, Ma'am" Akeno replied, her eyes never leaving the monstrous beast. "Let's take it down together. I don't want to break my promise."

Cerberus lunged towards them, one of its heads snapping viciously. Rias and Akeno swiftly dodged, their aerial maneuvers graceful yet calculated.

Rias unleashed her Power of Destruction, the crimson energy colliding with one of Cerberus's heads, causing it to reel back with a pained growl.

Akeno followed up with a bolt of lightning, striking another head and sending a surge of electricity through its massive body.

On the ground, Koneko moved with precision and strength, her fists glowing with energy as she targeted Cerberus's legs.

Each punch landed with a resounding impact, momentarily destabilizing the beast and creating openings for rias and Akeno to strike from above.

Despite the overwhelming size and ferocity of the enemy, Koneko remained calm and focused, her small form a stark contrast to the towering beast.

Meanwhile, issei stood at the side protecting asia and ready, his Boosted gear glowing with an intense red light. His boosts echoed through the battlefield, his power growing with each pulse. He kept a close eye on the battle, waiting for the right moment to transfer his accumulated energy to his teammates.

"Boost!" Issei shouted, his voice filled with determination as another surge of power coursed through him. He knew that his role was crucial, and he was prepared to support his friends in any way necessary.

As the battle raged on, the group's teamwork became more evident. Rias and Akeno continued to attack from the air, their coordination flawless.

Koneko maintained the pressure on the ground, her relentless assaults keeping Cerberus off balance. And Issei remained vigilant, ready to transfer his boosted power to whoever needed it most.

The battle against the monstrous Cerberus raged on as Rias, Akeno, Koneko, Issei, and Asia worked in perfect sync. Each member of the group played their role, their voices cutting through the chaotic sounds of combat.

"Issei, keep boosting!" Rias commanded, her crimson energy swirling around her.

"Got it!" Issei responded, his 'Boosted Gear' glowing brighter with each pulse. "Boost! Boost! Boost!"

Akeno hovered above, her eyes focused. "Let's keep up the pressure. Koneko, aim for its heads!"

"Understood," Koneko replied stoically, her fists glowing with energy as she landed a powerful blow on Cerberus's head, causing it to falter.

"Asia, stay close and heal anyone who gets hurt!" Rias added, her gaze never leaving the monstrous beast.

"Yes, Rias!" Asia nodded, her hands glowing with healing magic as she prepared for any injuries.

Amidst the battle, a powerful presence emerged from the shadows. Xenovia appeared, her Sword of Destruction gleaming with an ominous light.

Without a word, she charged forward, her sword slicing through two of Cerberus's heads with a single, powerful swing.

The beast let out a deafening roar as it staggered, two of its heads severed and falling to the ground. The team turned to see Xenovia, her expression fierce.

"Xenovia!" Rias called out, a mixture of and surprise in her voice. "You made it just in time!"

"I couldn't let you handle this alone," Xenovia replied, gripping her sword tightly. "We have a common enemy, after all."

Akeno smiled slightly, her usual playful tone returning. "My~ what a dramatic entrance, Xenovia."

"Better late than never," Xenovia shot back with a smirk.

As they exchanged words, the group regained their composure, the tide of the battle shifting in their favor.

Meanwhile, at a distance, Raizel stood facing Kokabiel, the air around them heavy with tension. The fallen angel's dark wings spread wide as the throne disappeared. He looked down at Raizel with a smug expression.

"It's a pleasure to meet you again, Noblesse," Kokabiel said, his voice dripping with mockery. "A relic of the past, interfering in the affairs of this era."

Raizel's crimson eyes narrowed, his calm demeanor unwavering. "Your ambition disrupts the peace of this world. You will not be allowed to continue."

Kokabiel chuckled, his voice echoing through the battlefield. "Peace? This world thrives on conflict. I seek to restore its true nature."

"You seek chaos and destruction," Raizel replied coldly. "I will not allow you to harm those under my protection."

With a wave of his hand, Raizel unleashed a surge of his power, the sheer force causing the ground beneath him to crack. Kokabiel's expression darkened as he felt the weight of Raizel's presence.

"Impressive," Kokabiel admitted. "But it will take more than that to stop me."

As the confrontation escalated, the battle between the group and Cerberus continued. With Xenovia's arrival the team pressed on.

While Rias, Akeno, Issei, Kiba, Asia, and the others fought fiercely against Kakabiel's minions, elsewhere, Sona and her peerage were hard at work. Inside the school grounds, now trapped within an impenetrable barrier, they meticulously analyzed the structure, searching for any weakness that could help them break through and reestablish communication with the outside world.

Tsubaki concentrated deeply, her hands glowing faintly with magical energy. "This barrier is intricate, far more advanced than anything we've dealt with before," she muttered, frustration evident in her voice.

Sona, standing beside her, nodded, her mind racing. "We must find a way. If we can just disrupt its core for a moment, we might be able to get a message out to the underworld."

As they worked tirelessly, the ground trembled slightly, signaling the ongoing battle. The urgency in their task grew as the sounds of combat echoed around them.

Meanwhile, on the battlefield, amidst the chaos, a sudden hush fell as a dark figure emerged from the shadows—valper galilei, the man responsible for the unholy experiments with the Excalibur fragments. His twisted smile spread across his face as he approached Kokabiel, who hovered above the ground, watching the fight with an air of amusement.

"Kokabiel-sama, the preparations are complete," Valper announced, his voice dripping with sinister pride. "The fragments of the Excalibur have been successfully merged. Behold, the ultimate weapon is ready."

With a wave of his hand, valper revealed a massive, glowing sword. Its blade pulsed with a malevolent energy, a fusion of all the Excalibur fragments—nightmare, mimicry, transparency.

The air around the weapon shimmered with raw power, its presence alone enough to send chills down the spines of those who could feel its destructive force.

Kokabiel's eyes gleamed with excitement as he descended to the ground, taking the weapon from valper's hands.

"Magnificent," he whispered, the thrill of power evident in his tone. "With this, I will raze the human world and the underworld alike. The age of peace will end, and chaos will reign."

He raised the weapon high, its energy crackling ominously. The sky darkened further, and a palpable tension spread across the battlefield. Rias and her group, sensing the shift, turned their attention to Kokabiel.

"What is that?" Issei asked, his voice filled with dread.

"A fusion of the Excalibur fragments," Xenovia replied, her grip tightening on her own sword. "Its power is beyond anything we've faced."

Rias stepped forward, her eyes narrowing. "We can't let him use it. If that weapon is unleashed, it could destroy everything."

The group readied themselves, determination etched on their faces.

Raizel, standing slightly apart, gazed at Kokabiel with a calm yet fierce intensity. His aura flared subtly, a sign that he was prepared to act.

"Everyone," Rias commanded, "we have to stop him here and now."

As the group prepared for the next stage of the battle, Sona and her peerage continued their efforts to disrupt the barrier. Time was running out, and the stakes had never been higher.
