....

On the battlefield, Koneko Toujou was locked in a fierce struggle against the Cerberus.

Despite her incredible physical strength, she specialized in close-range combat, making the hellhound's vicious flames and multiple snapping jaws difficult to handle.

The fight had reached a stalemate.

Watching from the sidelines, Xenovia Quarta couldn't hide her surprise. Rias and the others had dealt with their own Cerberus opponents so effortlessly, yet Koneko was still struggling?

Realizing the situation, Xenovia made her decision.

"Right now, we're allies, and we have a common enemy. It's only right that we help," Xenovia muttered, tightening her grip on Durandal before charging in.

A moment later, Irina Shidou, wearing a conflicted expression, followed suit, raising Excalibur Mimic in both hands.

Koneko landed a powerful punch to the Cerberus's gut, sending it staggering backward.

Seizing the opportunity, Xenovia and Irina struck simultaneously—two flashes of light, and in the next instant, the Cerberus's left and right heads were severed.

Koneko exhaled, gathering her Demonic Energy before activating her trump card—Eight Gates Release!

Her small fists clenched as a surge of raw power coursed through her.

"Haaaaah!!"

With a final devastating punch, she obliterated the last remaining head.

The Cerberus convulsed, twitching as blood sprayed across the ground—until it collapsed, lifeless.

....

Up above, Kokabiel watched the entire thing unfold. And instead of anger—he laughed.

"Hahahaha! Impressive! I thought you'd at least be injured after dealing with my 'pets,' but you've finished them off so easily."

His crimson eyes gleamed with twisted amusement.

"You're not just some minor brats—you're shaping up to be amongst the Top Underworld's New Generation. How… delightful!"

Kokabiel was not angered by the easy defeat of his Cerberuses. Instead, he was even more pleased and found the situation quite amusing.

I rolled my eyes. 'Keep laughing, You won't be smiling much longer.'

....

Meanwhile.

On the other side of the battlefield, Kiba Yuuto was locked in combat against a Stray Priest wielding a Holy Sword, while Valper Galilei stood at a distance, watching with a smug grin.

"Heh, I heard one of the test subjects escaped… and to think he became a Devil. How pathetic." Valper chuckled, shaking his head.

"But I should thank you, failures. Without your sacrifices, my research wouldn't have succeeded."

Kiba finished off the Stray Priest with a swift slice of his Demonic Sword before turning to Valper, his face grim.

"Succeeded? What do you mean?"

"Originally, the factors possessed by those of you with aptitude weren't sufficient to manifest the ability to wield a holy sword. So, I came to a conclusion: extract the adaptation factors from those with the aptitude."

"What?!" Kiba's voice dropped to a low, dangerous growl.

Ignoring Kiba's rising fury, Valper pulled out a small white crystal from his pocket and twirled it between his fingers.

"And then, we successfully crystallized the adaptation factors we extracted from you. What I'm holding in my hand is a crystal made from those factors. Of course, this is the last one. If you want it, you can have it. It's mass-produced now, anyway." Valper sneered.

He casually tossed the crystal at Kiba's feet.

Hearing this, Xenovia turned to Irina, shocked. "Isn't that what Holy Sword wielders receive during their blessing, implanted into their bodies? So, it was an item used to supplement insufficient adaptation factors."

Irina's face paled as the realization hit her.

She had been enhanced with the same factor that had been stolen from Kiba and his companions.

Guilt churned in her gut as she turned toward Kiba, her grip tightening around Excalibur Mimic.

Kiba, staring at the crystal in his hand with an agonizing expression, seemed to recall his former companions. Tears welled up in his eyes.

Their dreams. Their voices. Their lives—taken so cruelly.

After a long moment, Kiba glared at Valper with unbridled rage, shouting, "If that's the case, Why did you have to poison us? Why did you destroy their dreams?"

Valper simply laughed. "Why? Hahaha, you were nothing more than experimental materials—garbage, It's only natural to discard materials after they've served their purpose!"

Kiba's grip on his Demonic Sword tightened, veins bulging along his forearm. His entire body shook with an uncontrollable fury. "Valper… you're going to die."

In a flash, Kiba lunged.

"W-Wait! You can't—AAAAHHH!!!"

Before Valper could react, Kiba's blade tore through him in one clean motion.

The old priest's body split apart—his lifeblood spilling onto the cold ground.

Kiba stood there, panting heavily, blood dripping from his blade.

"I've finally... avenged you all..."

Kiba looked down at the crystal in his hand, recalling the past, and tears streamed down his face.

Suddenly, the crystal emitted a faint white light, which then enveloped Kiba. Finally, many figures radiating a pale blue light emerged from the crystal.

Kiba looked at them, and lowered his head sadly, his voice a mix of longing and sorrow. "I've always... always wondered if it was really okay... for only me to have survived."

"And now... Is it really alright for only me to live such a peaceful life?"

A faint, melodic hum filled the air, and one of the spirits—a young girl—stepped forward, gently tugging on Kiba's sleeve. then smiled at him.

Kiba turned to look at the little girl, and his eyes filled with tears.

The spirits began to circle him, their voices echoing in the wind:

"It's okay..."

"As long as we're together..."

"Accept it! Accept us!"

Hearing their voices, Kiba's tears flowed freely, but a happy smile spread across his face. "We... we are one! Thank you, everyone!"

Finally—the spirits transformed into specks of light and returned to Kiba's body.

....

Everyone present felt the warm and holy light, and they all smiled at Kiba.

Asia was moved to tears.

Kiba took a deep breath, then suddenly raised his Demonic Sword—

"Sword Birth—!"

A surge of divine radiance mixed with demonic darkness, fusing together into something entirely new.

His blade transformed, its new form exuding both holy and unholy energy—a perfect balance of light and shadow.

"Balance Breaker—Holy Demonic Sword of Twin Supremacy!"

Everyone stared in awe at Kiba's new weapon.

I scanned the scene, and seeing that everyone was looking at Kiba and his sword with confusion and surprise—I explained with a smile, "That is Kiba's Balance Breaker: Holy Demonic Sword of Twin Supremacy. He has overcome the shadows of his past."
