Suddenly—
Zip.
Denim threads shot from the shadows like living snakes. Before the guards could even gasp, the fibers wrapped tight around their mouths and limbs.
“Mmph—!”
In a split second, they were hoisted into the air and pinned silently against the tree trunks. Best Jeanist adjusted his collar, retracting the excess threads with a sharp tug.
“Guards neutralized.”
A crackle came through the earpiece. Hawks’ voice followed, clear and relaxed.
“Nice timing. Perimeter is clear. No heat signatures detected outside.”
Jeanist nodded, turning to the four heroes standing silently behind him—Mirko, Kendo, Komori, and Pony.
“I will monitor the situation from the outside and maintain a direct line with Hawks.”
He straightened his posture, his green eyes steady.
“The inside is up to you. Good luck.”
The four heroes didn't speak. They simply nodded, their eyes sharp and ready in the dark. Mirko cracked her neck lightly, a confident smirk touching her lips. Then, she signaled the team.
They moved toward the door like shadows.
Komori loosened the sprayer at her waist and carefully pulled the trigger.
“Shroom… spore dispersion, start.”
White spores drifted through the air, catching the fluorescent light—shimmering like silver smoke. Moments later, the villains inside began coughing violently.
“Cough— cough! What the hell— why can’t I breathe?!”
“Damn it! Turn on the vents! Get upstairs— hurry!”
As they scrambled toward the elevator—
Pony kicked off the floor with a shout.
“Horn Cannon!”
In an instant, four horns shot out in all directions. Two curved along the walls to block the elevator doors, while the other two speared forward, sealing off the corridor.
“No one’s getting out of here!”
The villains stumbled, tripping over each other—and that was when Kendo’s massive hand swept through the air like a wall.
“Escape blocked!!”
Then Mirko charged in right behind her.
“Luna Ring!”
A flash of white light ripped through the air before anyone could blink. Three villains slammed into the wall at once and collapsed. The metal door rattled. Silence followed.
A crackle came through the comm. Best Jeanist’s voice followed,
“First floor secure. Good work.”
He drew a short breath before continuing.
“But the key members are on the third floor. Resistance will get tougher the higher you climb. Keep every escape route sealed.”
Mirko nodded, tightening her fist.
“Got it. I’ll punch through to the top.”
Komori took a deep breath and pulled the trigger of her sprayer.
“Shroom… spreading now.”
White spores burst into the air, flashing under the lights like silver smoke. One of the villains rubbed at his face with a panicked yell.
“Ugh—what the hell? There’s mushrooms on my face!”
Pony stepped back, thrusting both arms forward.
“Horn Dash Hammer!”
Her horns shot out like lightning—hooking for a split second onto Kendo’s and Mirko’s shoulders, then whipping forward again to the center of the floor, sealing off the corridor.
“Hold the line!” Kendo barked, lowering her stance. “Front and back—clear them both at once!”
Mirko gave a short laugh, stomping the ground.
“Good. Come at me.”
Their rhythm clicked instantly. Kendo’s enormous hand slammed the door shut, and Mirko’s rapid kicks filled every gap. The villains stumbled over each other—and within seconds, the floor was cleared.
Mirko gestured toward Komori.
“Komori! Secure this floor!”
Komori’s mushroom-cap eyes widened; she nodded quickly.
“Shroom… understood.”
Mirko spun on her heel and sprinted toward the stairs.
“I’ll take the third floor and block their escape!”
Kendo started after her but stopped short.
This story has been taken without authorization. Report any sightings.
“Wait—let us go with you!”
Mirko shook her head.
“No time! The bosses are already on the run. I’ll hunt them down—you hit the front!”
Then she launched herself up the stairway. A white streak flashed up the stairs as she vanished into the next floor.
Red emergency lights pulsed, sirens low and distant. The ceiling vents rattled, metal groaning with every rotation. The air trembled—so tense that even a breath echoed.
“Stop her! Whatever it takes!”
The Onishi brothers, clutching a crate of Trigger vials, bolted toward the emergency exit. Behind them, several lieutenants yanked syringes from their belts and jammed them into their arms.
“Forget running! We finish this here!”
Before the door could open—
KRAAANG!
Mirko’s kick smashed through the steel emergency door, crushing it inward. Sparks flew; the metal twisted like paper.
“No exits,” she growled. “The rabbit just sealed the burrow.”
She lunged forward. Her first punch shattered a jaw; her second kick sent another flying into the wall. But the remaining thugs plunged their Trigger ampoules all at once.
“Krrrrr—!”
Their skin flared red as if set ablaze, veins crawling up to their eyes. Their pupils shrank to feral slits. Some screamed as their arms twisted and hardened into metal.
Mirko gritted her teeth and shouted into the comm.
“Kendo! Pony! Komori—get up here, now! I’ll take the Onishi brothers!”
She rolled her shoulders, fist tightening. Muscles surged beneath her skin.
“All right… let’s do this for real.”
She stepped forward. The metal floor split beneath her heel. The elder Onishi lunged, swinging hard—but Mirko slipped past and snapped out a kick.
“Luna Arc!”
Her foot carved a crimson arc through the air, the shockwave rattling the walls as his body folded and crashed to the ground.
“Damn it!”
The younger Onishi lunged—
“Luna Ring!”
Mirko’s kick slammed him into the wall. Metal shrieked as Trigger syringes clattered across the floor.
Breathing hard, she threw both arms up.
“Good. Mission complete.”
A short, cocky smile crossed her lips.
“My body’s back to full—”
Then—
The air warped, faintly twisting as if reality itself had buckled.
"…Be careful…"
The familiar, hollow voice broke apart in the air like dust. Her rabbit ears twitched.
At that instant, a berserk villain lunged from behind. His hair shot out in tendrils, wrapping tight around Mirko’s left arm.
“Kh—!”
The pressure bit into her skin like steel wire. Her bones groaned, screaming under the strain. Then—Shigaraki’s voice echoed again.
“Just like back then… your arm might twist again.”
Mirko’s vision warped. Light flared. A high, piercing shiiiii— flooded her ears. For a heartbeat, her mind went white.
Not this time!
Her breath caught—her eyes flared red. Her right foot slammed down, recoil snapping through her spine as she spun. She twisted with the pull, caught his neck, and slammed him to the ground.
She paused, panting—
Zzzk.
Something wrapped around her right leg. Her body staggered. Fibrous strands, like hair, dug into her calf, and pain ripped through her skin—bones grinding beneath it.
And then—
“If you get hurt that bad again… you’ll have to cut it off.”
Shigaraki’s voice slid into her ear—cold breath grazing her skin. Her pupils blew wide. Her breath locked. For an instant, the world went still.
What flashed through her mind was pain—a pain that refused to fade.
The right leg that had once been skewered by those black tendrils. The sound of tearing flesh ringing in her ears. The smell of hot blood and iron rising from the severed edge.
“It’ll take months before you can run again.”
Yoshida Ryu’s voice echoed inside her skull. And then—that day when she’d given up on rehabilitation and chosen amputation herself.
No time. I have to get back to the front.
That same resolve returned, frozen and unyielding.
“Stop…!”
Her red eyes flared. The air tore open, silence snapping apart around her.
“Luna Rush!!”
The rabbit’s legs cut through the space, leaving white trails like a storm unleashed.
Kendo, Pony, and Komori had just finished subduing the last of the villains, panting hard. Trigger ampoules rolled across the floor, and the spores faded into the still air.
Kendo wiped the sweat from her brow and shouted,
“Mirko! We’re all clear down here!”
A crash thundered nearby.
Mirko was still fighting. Her legs whipped out like lightning—the wall split apart under the impact. Pony’s eyes went wide.
“Still crazy fast! That’s awesome!”
Komori swallowed hard.
“W-wait…”
All three turned toward Mirko at once.
Her gaze—those red, gleaming pupils, the eyes of a beast stripped of reason. Kendo murmured under her breath.
“…Mirko?”
No answer.
Mirko’s leg was still slamming down, again and again. Her expression held no certainty of victory—only a tangle of fear and rage. And at the edge of her ears, the rabbit still trembled at an echo no one else could hear.
The villain’s head slammed into the floor. The air burst with iron and dust, sharp and metallic on her tongue. But Mirko didn’t stop.
Her breath burst out, legs tightening again. Muscles coiled like fire, ready for another leap—this time aimed straight for his skull.
The air itself tensed.
“Luna Fall.”
Just as the air was about to tear—
“Mirko!!”
Kendo’s shout cracked through the room like thunder.
A massive hand caught Mirko’s arm mid-motion. Bone cracked against bone as their forearms collided. At the same time, Komori’s spores burst into a white mist. Vision blurred; the air trembled faintly around them.
“Shroom… please, stop…!”
Pony’s horn shot forward, grazing Mirko’s foot before slamming into the floor. Sparks burst across the narrow room.
“Get out of my way!!” Mirko roared, baring her teeth.
Her eyes were wild—the same eyes that once stared through fire and blood. For a heartbeat, she was pure motion—madness made flesh. Her leg twitched mid-air. One more inch, and the villain’s head would have shattered.
“Mirko-san, stop!”
Kendo’s voice shook. Pony’s face had gone pale, and Komori clung to Mirko’s arm, eyes wet. Only their breathing filled the room.
Mirko’s shoulders rose and fell, heat surging with every inhale, exploding out with every exhale.
Then—slowly—her vision cleared.
Beyond the red haze, the villain was still breathing, faint but alive. The strength drained from her shoulders. The red glow in her eyes began to fade. A long breath slipped out, cooling the heavy air.
For a moment, no one spoke.
Mirko staggered forward a few steps, both hands clutching her head. Her folded rabbit ears trembled.
Kendo stepped forward carefully.
“Are you alr—”
The moment her fingertips brushed Mirko’s left shoulder, the world tore open.
The air buckled; light bent with it. The floor tilted; the walls sagged and melted like wax.
In an instant, the space before her twisted into the underground of Jaku Hospital.
The stench of metal. Blood. The creak of machinery. Somewhere, screams. Breaths thick with pain.
A High-End Nomu reached out its arm. Its hand slowly clenched, and the air itself lurched—bent and shuddering.
And then—
Her left arm twisted. Bone shattered. Muscle ripped. Blood burst out, hot and slick, running down her skin. Her nerves screamed, a surge of fire racing through them like current.
“—!”
Her breath stopped. Light exploded across her vision, painting everything red.
“Let go!!”
Mirko’s scream tore through the silence. Her arm swung on reflex.
“Ah—!”
Kendo staggered back several steps, struck across the wrist. She lost her balance and hit the wall, clutching her arm. Her eyes widened—shock, and a flicker of fear she couldn’t hide.
Pony and Komori froze where they stood, fear flashing through their eyes for a split second. Even the sound of breathing vanished.
The air grew heavy—thick as lead.
Mirko stood frozen.
Her fingertips trembled, breath ragged and uneven. She stared down at her own hand, her eyes clouded with disbelief, fear, and deep confusion. Her ears drooped slowly, hanging limp.
“I’m… sorry.”
Mirko’s voice shook. The violent rhythm of her breathing began to fade, her shoulders sinking little by little. Her voice cracked—what remained inside it was only exhaustion, and guilt.
She lowered her head. hiding her face in the shadow of her hair.
“……”
After a moment, she turned away without a word. Her steps were heavy, measured—as if afraid to stir the air she’d broken. Her metal boots scraped faintly against the floor.
No one stopped her. That silence rang louder than any cry.
At the end of the flickering corridor, her rabbit ears swayed once—and vanished.
Pony opened her mouth to speak, but no sound came out. Komori gripped the brim of her mushroom hat tightly, her head bowed low. Kendo could only steady her breathing, her eyes locked on Mirko’s fading silhouette.
?In the absolute stillness, the remaining spores from the battle began to settle.
?Drifting down through the red emergency light, they fell slowly, silently—like silver snow covering a battlefield, burying the pain in white dust.
