I Don't Own anything except my OCs

Akio Takeyama's name once echoed through the halls of U.A. High School, a promising student destined to stand among the greats. His quirk, Kinetic Absorption allowed him to absorb kinetic energy from any impact and use it to enhance his speed, strength and redirect it as a devastating shockwave. Though he was often overshadowed by his older sister, Yu Takeyama, better known as the pro hero , Akio was determined to forge his own path.

Yet, for all his potential, Akio was declared dead nine years ago—a tragic casualty during his internship with a small-time pro hero agency. His sacrifice to save dozens, including a young Izuku Midoriya, became one of U.A's most heart-wrenching stories. But Akio's story did not end in rubble. It was merely the beginning of something darker, something that would change the hero world forever.

The building groaned ominously, its foundation cracking under the force of the villain's attack. Flames licked at the edges of shattered windows, smoke curling into the sky like a shroud of despair. Screams echoed through the chaos as civilians scrambled to escape the collapsing structure.

Among the chaos stood Akio, a third-year U.A student on his work study with the pro hero Death Arms. His dark teal hair was matted with sweat and soot, and his crimson eyes burned with determination. Despite the terror around him, his focus remained unshaken.

But inside, his emotions churned like a storm. Fear clawed at the edges of his mind, whispering doubts he refused to entertain. He clenched his fists, calming the raging storm of emotions inside "Not now," he muttered to himself. "People need me."

"Takeyama! Fall back!" Death Arms voice cut through the chaos. "This building's coming down any second!"

Akio shook his head, stepping forward. "There are still people inside," he said firmly. "I can hold it long enough for them to get out."

Death Arms hesitated, torn between his duty to protect his sidekick and the lives of those trapped within. Before he could respond, Akio dashed inside, his quirk activating as he ran. A faint, shimmering purple glow enveloped his body, glowing brighter with every piece of debris that struck it. The kinetic energy of each impact was absorbed into his body, stored like fuel waiting to ignite.

The interior of the building was a nightmare. Smoke choked the air, and the heat was suffocating. Each breath burned his lungs, but Akio pressed on. Every step felt like a war against his body, his muscles screaming under the strain. His quirk flickered as chunks of concrete rained down around him, forcing him to redirect the absorbed energy in short bursts as he near the limit of the energy his quirk could absorb

"Just a little more," he whispered through gritted teeth. He couldn't stop now. He wouldn't.

He found a group of people huddled under a makeshift shelter of desks and led them toward the exit, using bursts of redirected energy to clear their path. Each impact drained his stamina, and the weight of the building seemed to bear down on him. Still, Akio pushed on, his mind focused on one simple mantra: Just one more.

In the farthest corner of the building, Akio found a young boy with messy green hair and wide, tear-filled eyes. The boy—no older than six—was clutching a worn All Might action figure to his chest, trembling as the world crumbled around him.

"Hey, kid," Akio said gently, kneeling to the boy's level. His voice was calm, but inside, his heart raced. The weight of responsibility felt like a crushing tide, but he pushed it aside. "What's your name?"

The boy sniffled, his voice barely audible. "I-Izuku."

"Izuku, I'm going to get you out of here, okay?" Akio extended a hand, offering a reassuring smile. "Stay close to me."

Izuku nodded hesitantly, slipping his tiny hand into Akio. Together, they navigated the wreckage, Akio's quirk absorbing the constant barrage of debris. Each step felt heavier than the last, his stamina nearing it's limit. Sweat dripped down his face, mixing with soot and ash, but he kept moving.

As they approached the exit, a deafening crack echoed through the building. The ceiling above them began to collapse, massive chunks of concrete hurtling toward them.

Akio didn't hesitate. He scooped Izuku into his arms, turning his back to the falling debris. His quirk flared brightly as the kinetic energy of the impact surged through him, threatening to overload his body. The pain was immediate and excruciating, like fire coursing through his veins. With a roar, he unleashed the stored energy in a powerful blast, clearing a path through the rubble.

The blast carried them to the entrance, where first responders and pro heroes were waiting. Akio stumbled forward, placing Izuku into a pro hero's arms. His legs felt like lead, and his vision blurred at the edges.

"Get him out of here," Akio said, his voice strained and ragged. Each word felt like a monumental effort.

"What about you?" The hero demanded.

Akio glanced back at the building. More people were still inside. His chest tightened, but not from fear—from resolve. "There's more people to save."

The hero hesitated but nodded, retreating with Izuku. The boy looked back over the hero's shoulder, his tear-filled eyes locking with Akio's.

Akio gave him a small, reassuring wave before turning back to the collapsing building. Each step felt like an eternity, his body screaming for rest. But he couldn't stop. Not yet.

When the building finally came down, it was with a deafening roar. The explosion of dust and debris blanketed the area, and the world seemed to hold its breath. Rescue teams worked tirelessly to dig through the rubble, pulling survivors from the wreckage. But Akio Takeyama was never found.

His name was etched into the hearts of those he saved that day, a hero who gave everything to protect others. For Izuku Midoriya, Akio became the embodiment of heroism—a shining example of selflessness and courage.

The funeral was small but solemn, a tribute to the young hero who had given his life to save others. Mt. Lady stood at the front, her normally bright and confident demeanor replaced by a quiet sorrow. She clutched the podium, her hand trembling, as she prepared to speak about her brother.

"Akio was not just my brother... He was my inspiration," she began, her voice shaky. "He had a gift-an energy-like no other. But more than that, he had a heart that couldn't turn away from helping those in need. It didn't matter who they were, or how difficult the task, Akio would always stand in the way of danger, never backing down. His courage… his sacrifice… was not for fame or glory. It was for the people he loved, and for the heroes he believed in."

Her voice broke, but she pushed through, her eyes scanning the crowd. Among the mourners was a young boy—Izuku Midoriya. His eyes wet with tears, remembering Akio's strength and drive as he saved him.

After the speech, Izuku and his mother approached Mt. Lady quietly. She turned to him, her face softening as she saw the boy standing there, his hands clenched at his sides.

"Ms. Mt. Lady," Izuku started, his voice barely above a whisper. "I'm so sorry about Akio... He saved my life. If it weren't for him…"

Mt. Lady placed a hand on his shoulder, her face a mixture of pride and sadness. "He saved so many people, Izuku. And he would've saved more if he had the time. He didn't think twice. He protected you, but in a way, he protected all of us, even those he didn't know."

Izuku nodded, his eyes filled with gratitude and guilt. "I don't know if I'll ever be able to repay that. He gave his life for me."

"You don't have to," Mt. Lady said, her tone firm but kind. "Akio didn't do it for repayment. He did it because he believed in the future. He believed in people like you—heroes who never stop fighting, no matter what. The best way to honor him, Izuku, is to carry on. To be the kind of hero who would lay down their life for others."

Izuku's eyes glistened with tears, and he wiped them away quickly. "I promise, I'll never forget Akio. I'll be a hero who can live up to his sacrifice."

Mt. Lady smiled softly, her voice steady. "I know you will."

And as the wind swept across the graveyard, it carried with it a quiet promise—the legacy of Akio, the shield that saved so many, would live on in every hero who followed.

Nine years later, the name Akio resurfaced. But this time, it wasn't in a story of heroism or sacrifice. It was whispered in the shadows, among those who opposed the hero system.

The leader of the vigilante group known as the Revenants had emerged, his face concealed behind a mask. His voice carried the weight of a man who had seen the truth behind the hero society, and his mission was clear:

Dismantle the corrupt system. Restore true justice.

And behind the mask, crimson eyes burned with the same determination that once drove Akio Takeyama to save lives, even at the cost of his own.
