The Assassin's Hymn {KNY x Assassination Classrooom}

A final surge of icy wind tore through the battlefield, shimmering like glass, cutting through her body with merciless precision. Crimson bloomed across the torn fabric of her uniform.

Her knees buckled.

Her swords slipped from her grasp.

She collapsed.

"No—NO!" Karma's scream ripped through the frozen air. Despite his classmate's protests, he ran towards the collapsed female.

Muichiro, his katana slipping from his trembling hands, could barely process what had just happened. His breath came in ragged gasps as he stumbled forward, his vision blurred with tears.

"No... Not again—"

Sanemi, covered in blood, his body barely holding itself together, stood frozen. He had seen death, he had known loss, but nothing—not even his family's death—felt like this. His breathing was sharp, uneven. Not her. Not her.

The battlefield was silent, save for the eerie crackling of ice beneath Douma's feet. He tilted his head, feigning sympathy. "Such a shame." His voice dripped with mockery. "You all fought so hard. But, in the end, she was nothing more than another name to be forgotten."

Sanemi moved to lunge, but Douma was already fading into the shadows, his laughter lingering like a ghost.

Karma didn't care. He didn't care about Douma. He didn't care about the others. The only thing that mattered was the girl lying motionless in the bloodstained snow.

He fell to his knees, gripping her shoulders. Her breathing was shallow, her once-bright eyes barely open. The warmth was already leaving her body.

"You're not going anywhere," he whispered, his voice breaking.

She tried to smile. Even in her final moments, she still wanted to reassure him. Her trembling hand reached for his cheek, her fingers barely brushing against his skin. "You always... make things so difficult, Karma-kun" she murmured, her voice weak, but teasing.

Karma let out a shaky laugh, his hands gripping hers tightly. "You can't die. You promised—" His voice cracked. "You promised we'd get out of this together, remember."

She let out a breathy laugh that quickly turned into a cough. "Of course, how could I forget, the tiny, afraid boy with red hair who was right around my age, out beating people up because they hurt his friend, prone to a demon attack."
"W-we'll go get a doctor, right? That takoyaki can fly at an inhumane speed, surely-" he turned around but was met with Koro-sensei looking away.

"Sorry, I won't be able to fulfill that promise, maybe next time." And for the first time in her life after the death of the Flower Hashira, she let out a smile, a genuine one.

"No, you're going to keep your eyes open, please."
But she didn't respond. Her breaths grew fainter, her fingers slipping from his grasp.

"No... No, no, no—" His hands shook violently. His vision blurred. He pressed his forehead against hers, his entire body trembling. "You can't leave me. Not you."

Muichiro had fallen to his knees beside her, his hands hovering uselessly over her wounds. He wasn't breathing properly. The cold had nothing to do with the way his chest ached.

He had already lost one family. And now... he was losing another.

Sanemi clenched his fists so hard his nails pierced skin, drawing blood. He wanted to scream. He wanted to destroy everything in sight. But the only thing he could do was watch—watch as the last traces of life faded from her eyes.

The sun had fully risen now, painting the battlefield in soft gold. But there was no warmth. Only the sound of Karma's broken sobs.
Muichiro gripped her hand, squeezing so tightly it should have hurt—but there was nothing. No response. Just cold, lifeless fingers.
Sanemi turned away, biting down so hard on his lip that blood filled his mouth. He had seen death. He had seen too much death. But this—this was unbearable.

And then, Karma screamed.

It wasn't just grief—it was something raw, something that tore through his throat and burned the air around him. It was a sound that didn't belong to a human but to a soul being shattered beyond repair.

The class stood frozen, their bodies numb, their hearts heavy with unspeakable sorrow. She was gone.

But her story wasn't over.

Karma wiped his tears away with a shaky hand. He lifted his head, his eyes burning with something new. Something dark. Something unbreakable.

"We're going to kill him." The Mist Hashira's voice was quiet, but it carried across the battlefield. "We will make him pay."

He lifted his head, his eyes dark with silent fury. Sanemi exhaled sharply, gripping his blade so tightly it trembled in his grasp.

They had lost their brightest star. But they wouldn't let her sacrifice be in vain.

The war wasn't over.

It had only just begun.
