"KAZUKI-SENPAI!!"
Yumi screamed, her body already leaning forward to sprint toward him, then an overwhelming surge of fighting spirit erupted. 'What the hell was—!?'
"And where do you think you're going, young lady?"
Grayfia stopped Rias, who had tried to dash toward Kazuki after seeing him struck down by Vali Lucifer.
"Where else?! We're going, Akeno!!"
"Yes!!"
Rias shouted in a frenzy. 'Tch.' Grayfia had thought she'd matured somewhat, but it seemed she still had a long way to go.
"Calm yourself, Rias."
The moment Grayfia spoke not as a maid but as her elder sister, Rias stiffened, biting her lip in frustration.
Honestly, she could stand to take a page out of Sona's book—the Sitri heiress was just as worried, yet she kept her composure and assessed the situation.
"Still… Vali Lucifer. Her combat instincts are terrifying."
"Damn right. Told ya, Michael—she's the strongest White Dragon Emperor."
Azazel bragged like an idiot. 'Wait, no—he was an idiot.' The guy had just gotten a hole blown through his gut, and here he was, running his mouth.
"S-Serafall-chan… Do you think Kazuki-kun will be okay?"
"…He'll be fine, Sona. A man like him doesn't end here."
Though Serafall answered Sona's anxious question with confidence, even she seemed to be trying to convince herself, her teeth clenched as she stared at Kazuki's fallen form.
'Kazuki… Is this really where you fall? That night, you defied my expectations and left me in awe. Show me that side of you again.'
At that moment…
An overwhelming fighting spirit suddenly erupted across the battlefield. 'What the hell—!?'
The fight with Kazuki Fuwa had been fucking incredible.
Lately, Vali had grown so strong that she rarely found a battle that truly satisfied her. She wouldn't go as far as to call herself the strongest yet, but at this point, only those on Azazel's level stood a chance against her.
Kazuki was still alive, it seemed, but Vali had enjoyed the fight to her heart's content, utterly satisfied.
"That was fun, Kazuki-kun. Let's do it again sometime."
With those words to the man who had given her such pleasure, she turned to leave—
BOOOOM!!
"——!?"
A sudden, overwhelming aura exploded behind her, forcing her to leap back on instinct.
"What the hell—!?"
Her heart hammered against her ribs as scorching heat threatened to consume her, cold sweat dripping from every pore. But she steeled herself, glaring at the source—Kazuki, slowly rising to his feet in his Balance Breaker armor.
"…I remembered something."
Step by step, Kazuki advanced toward her.
"The Enmei-ryu Style sought to become the strongest on earth, boasting an undefeated legacy spanning a thousand years through countless battles. But the Fuwa Enmei-ryu Style thrived in the shadows of history, refining the art of killing for just as long, a style of slaughter.
My grandfather drilled it into me, half by force. In a peaceful world, it had no use, and I figured it'd die with me. But after being reborn as a devil and throwing myself into battle… something stirred. My body, my heart—no, the very blood in my veins. The blood of the Fuwa refuses to accept defeat.
—Vali Lucifer. You're strong. Descended from a Maou, wielding the power of a legendary dragon. But I won't lose again. Not now. Not after remembering the blood I carry… the name Fuwa."
With each step he took, the blazing aura around him intensified, forcing Vali's guard to its peak as she instinctively fell into a stance.
"Hmm… Then show me what that blood of yours can do!!"
She struck first, but Kazuki effortlessly parried and countered. Blows, kicks, throws, joint locks—his techniques were relentless, pushing her back. She slashed, swept, and even halved his power to retaliate.
Their clash was even, damage mounting on both sides—until—
"Heh… Fufufu—"
"Hah… Hahaha—"
Before she knew it, Vali was laughing-no, no, moaning—in exhilaration.
'Ahh… This—this is pure ecstasy!'
Her once-pristine white armor lay shattered, splattered with blood and dirt. She was nearing her limit, yet the thought of stopping never crossed her mind.
She had always lived for battle. Even before Azazel found her, before she awakened as the White Dragon Emperor, fighting had been her purpose.
'Combat was pleasure.' Only in the throes of battle did she truly feel alive. But enemies strong enough to satisfy her were rare—only the very elite of each faction could push her this far.
If peace were to take hold, she'd lose even that. That was why she had accepted the Khaos Brigade's invitation.
And now, she was drowning in euphoria.
A searing spin kick grazed her neck. A fist wreathed in flames smashed into her, the impact resonating deep into her core despite her damage reduction. She shuddered, her body trembling with perverse delight as she struck back.
'Ahh… Yes! This—this is what I craved! This rapture! This bliss! I—I can't—I'm already—soaking wet!!!'
With every exchanged blow, every clash of their very souls, Vali's thighs grew slick with arousal, her breath coming in heated gasps.
"Kazuki…"
Kazuki and Vali. The two of them fought—grinning, laughing, reveling in each other's lethal strikes.
"As I thought… He still had another level beyond this."
"Big Brother…?"
Rias looked up at Sirzechs, who watched the battle with an almost expectant calm.
"I've felt it since the day we fought. He's always had… a Limiter."
"A limiter…?"
"Are you saying he was holding back even then?" Grayfia asked.
"No. He was serious—but only within the bounds of his reason." Sirzechs' voice was low, intense. "What you see now is his fighting spirit unleashed—a completely different beast."
"…That monstrous aura… It's like an 'Asura'!" Azazel muttered.
He was right.
The Kazuki before them now was nothing short of 'Bloody Demon'. Swallowing hard, Vali—no, everyone—could only watch as the battle reached its inevitable, climactic end.
