The battlefield smoldered, blue fire fading into the ash-laden air as Shoto and Kuri stood over Dabi. Shoto's chest rose and fell with labored breaths, his body still glowing faintly with the aftermath of Phosphor. Kuri's black and red wings stretched wide behind her, a protective shield as she stood at his side, her empathy quirk trembling with the echoes of pain radiating from her brother.

"He's down," Shoto said, his tone cautious but filled with resolve. "We can't let him get back up."

Kuri hesitated, her heart catching as she looked at Dabi's still form. Despite all he had done, the storm of anguish she felt coming off him was overwhelming. "Toya…" she whispered, her voice shaking. "Why can't you stop?"

But her answer came in the form of a low, rasping chuckle. Dabi's body shuddered, and his voice, weak yet defiant, broke the tension. "Stop? Do you think you've won?" His cracked lips twisted into a grin as his charred body began to rise, flames flickering to life around him once more. "You're still just kids… and I'm not done burning."

Shoto stepped forward, ice coiling around his arm, but Dabi was faster. A sudden burst of blue fire erupted from his hands, forcing Kuri and Shoto to shield themselves. When the flames subsided, Dabi was gone, a trail of fire leading toward the heart of the battlefield.

"No!" Shoto shouted, his voice tinged with frustration. He turned to Kuri, his mismatched eyes blazing. "He's going for my father."

Kuri's wings unfurled fully, the red-black feathers gleaming in the light of the inferno. She launched into the air, her voice urgent. "We can't let him reach Endeavor!" Shoto followed her, ice trailing in his wake as they took flight toward the distant figure of their father.

Endeavor stood across from All For One, the villain's dark energy radiating out in waves. Nearby, Kaori faced him as well, her stance firm, her expression unreadable. The oppressive aura made every breath heavy, but neither wavered.

The battlefield burned with intensity, blue fire and crimson energy clashing as Dabi's arrival heightened the tension. Above it all, All For One stood like a dark titan, his presence suffocating, his grin sinister. Kaori stood firm, her green eyes blazing, her hands glowing faintly with the power of Not For Any. Beside her, Endeavor's flames roared, his jaw set in determination.

All For One took a mocking step forward, his voice smooth and laced with venom.

"You're bold to face me together," All For One said, his voice smooth and mocking. "But then again, failure unites even the most unlikely pairs, doesn't it?"

Kaori's sharp green eyes narrowed, her hands glowing faintly with the power of Not For Any. "I don't have time for your taunts, All For One," she said coldly. "Let's end this."

She raised her hand, summoning a barrier of translucent energy to block his path as she moved in with precision strikes. The barrier shimmered with her power, glowing faintly as it repelled All For One's advancing quirk.

Endeavor followed her lead, flames spiraling around his fists as he lunged forward. "Incinerate!" he roared, unleashing a fiery barrage that engulfed the villain. The heat was blinding, the intensity cracking the earth beneath their feet

But All For One stepped through the flames, his aura of malevolence unbroken.

His smirk widened, his attention shifting between her and Endeavor. "You've both failed so gloriously as parents, haven't you? Kaori, the great wielder of Not For Any, abandoning your grandson, abusing your granddaughters… and look where it brought them. Into the arms of the heroes trained by Toshinori Yagi—the very man you despised. If the two of you had trained Kuri together to use Not For Any long ago you would have defeated me already. Instead you defeated yourselves for me. All it took was a petty disagreement over the morality of removing quirks. When mine was the one you needed to worry about. Fools!"

Kaori's jaw tightened, but she didn't respond. All Might gave her a pointed look.

Kaori's eyes flashed with anger as she raised another barrier, this time embedding it with Not For Any's energy. It pulsed as she pushed it forward, aiming to suppress his quirks. "You'll never understand," she hissed, the barrier slamming into All For One and forcing him back a step.

"Oh, but I understand perfectly," All For One replied, his grin widening. "Your failure wasn't just your own, Kaori. You passed it on to your descendants. Your precious granddaughter, Kuri, is just as broken as you are—always giving, always sacrificing. And Hawks? Cast aside because of his gender. A brilliant move on your part. It saved me the trouble of breaking him myself."

"And you, Endeavor," All For One continued, turning his crimson gaze to the Flame Hero. "You built your legacy on the backs of your children, treating them as tools to surpass All Might. Yet here you are, standing on the battlefield, trying to repair what you broke. Tell me—does it feel good to fail as both a hero and a father?"

Endeavor's fists ignited, his flames roaring to life as he stepped forward. "Say what you want about me," he growled, his voice filled with fire. "I'm still here to stop you."

Kaori summoned another barrier, this one larger, attempting to pin All For One in place. "We won't let you distract us," she said, her voice firm as she poured her energy into the construct.

Endeavor seized the moment, his flames roaring to life as he charged in with a precision strike. "Prominence Burn!" The attack lit up the sky, a radiant inferno aimed directly at All For One.

But the villain countered, his quirk absorbing part of the impact as he retaliated with a blast of air pressure that sent both Kaori and Endeavor staggering. His laughter echoed, dark and mocking. "Do you think your combined strength can match me? I've lived for centuries, molded the world in my image, while you've been chasing after your own failures."

Kaori pushed herself back up, her barriers forming once more as she muttered under her breath. "You don't know when to shut up."

Before All For One could reply, the sound of crackling fire filled the air. A trail of blue flames cut through the battlefield as Dabi arrived, his body battered but his resolve unbroken. His voice rang out, raw and filled with fury. "Old man! You're not done with me yet!"

Endeavor's eyes widened, a flicker of disbelief flashing across his face as he turned to see his son. "Toya…" he whispered, his voice trembling. "You're—"

"Still alive?" Dabi interrupted, flames surging around him. His twisted grin returned as he took his place beside All For One. "You're not getting rid of me that easily, Dad."

Far above the chaos, Izuku Midoriya hovered on the edge of another battle, the glowing green energy of One For All crackling around him. But his gaze was locked on the clash unfolding in the distance. The flames of Endeavor lit up the battlefield, Kaori's barriers shimmering as they held against the overwhelming force of All For One.

His chest tightened as his mind drifted to Kuri. She was out there somewhere, fighting her own battle alongside Shoto. His beloved, with her red-black wings and her unrelenting strength, who always gave everything for the people she loved. His grip on his power wavered for a moment as the thought of her in danger clouded his focus.

Suddenly Deku saw wings beat the sky. His green eyes followed her flight path as Kuri and Shoto flew toward the scene, the heat from Dabi's flames washing over them. Kuri's wings beat hard against the scorching air, her chest tight as she processed what was unfolding below. Her empathy quirk pulsed painfully as she felt the collision of emotions—Dabi's rage, Endeavor's guilt, Kaori's quiet fury, and All For One's calculated malice.

"She'll be okay," he whispered to himself, trying to steady his breathing. But the scene in front of him made it hard to hold onto that hope. All For One was a force unlike anything he'd ever faced, and the idea of Kuri coming into contact with that monster chilled him to the bone.

All Might's voice echoed in his mind, a reminder of the responsibility he carried. "You're the one who will carry on the legacy. You're the one who must end this."

Deku's jaw tightened as he refocused, clenching his fists. "I have to trust her," he muttered. "I have to trust all of them."

But even as he said it, his heart ached with worry. His mind filled with images of Kuri's determined face, her wings spread wide as she dove into the chaos. The connection they shared tugged at him, a constant reminder of the bond that drove him forward.

A distant cry broke through his thoughts, carried on the wind. It was raw, desperate, and filled with emotion.

"KEIGO!"

Kuri's voice pierced the air, and Deku's heart sank as he turned toward the sound, dread clawing at his chest.
