Mash Burnedead has watched his friends die more times than he can count. Finn, betrayed. Lance, broken. Dot, gone. And Lemon—he can't even finish the thought.
The world isn't rewinding time. It's rewriting cause and effect itself, dragging everything toward despair again and again. Every morning, Mash wakes in the Noir Forest with his adoptive father Regro, bakes cream puffs, and walks the same road to Granverdo Magic Academy. Every morning, he straps on a fake birthmark to hide the truth: he's
Mashle Rewrite: Smashing Fate with Muscle - Father, brother, and muscle—a strike against rewritten causality
Before dawn.
The sky was still dark, like spilled ink.
Mash Burnedead walked through the academy's underground passage. His black mushroom-cut hair clung to the damp air. His deep brown eyes stared straight ahead. In his hand, an iron staff. Heavy.
Four sets of footsteps followed behind him.
Finn Ames. A boy with black hair, blond on the left side only. His freckles floated in the faint light. The straight mark beneath his right eye. His face held no hesitation now.
Lance Crown. Pale silver-blue hair. Blue eyes. A pendant with his sister's photo around his neck. He walked expressionless, testing each step.
Dot Barrett. Spiky red hair and a bandana. Fists clenched, gait ready to burst forward at any moment.
And Lemon Irvine. Semi-long blond hair with a red ribbon. Her big red eyes wavered nervously in the dark.
"Mash, are you sure I shouldn't be going to Anna's side?"
Lemon said quietly.
"Yeah. You protect Anna."
Mash didn't turn around.
"But I want to fight alongside everyone too. As your future fiancée, by your side, Mash..."
"Lemon."
Mash stopped.
Slowly, he turned.
His deep brown eyes caught Lemon straight on.
"If you protect Anna, Lance can fight at full strength. Finn too. Dot. And me. So—please."
Lemon's red eyes shook.
"...Mash said 'please' to me."
Lemon clasped her hands in front of her chest.
"Understood. I will protect Anna without fail. So all of you—please come back safely."
"Yeah."
A short reply.
But to Lemon, it sounded like the surest promise in the world.
"Lemon, Anna's in your hands. She's my little sister. Don't let her get a single scratch."
Lance said in a low voice.
"Of course. And Lance—stay safe. Anna is waiting for you."
"...Yeah."
Lance's blue eyes softened, just for a moment.
Lemon bowed deeply to the four, then headed back the way they'd come.
The four watched until her red ribbon vanished into the dark.
"Let's go."
Mash faced forward again.
The passage grew deeper, darker.
The walls reeked of mold. Torch flames flickered, stretching their shadows long.
After a while, Mash's feet stopped dead.
"...Something's off."
"What is it, Mash?"
Finn stepped up beside him.
"This fork. Wasn't here before."
Mash looked at the passage splitting in two.
Right and left. Both equally dark.
"Before...? You've been in this passage before?"
"...Yeah."
Mash said nothing more.
Memories of the future. A world repeated over and over. In all of them, this passage was a single straight line.
But now it forked.
"So the enemy's a step ahead."
Lance said sharply.
"Probably. There are traps. One side, or both."
"Then I'll blast through! The protagonist of this world doesn't stop for a few traps!"
Dot raised his fist.
"Wait, Dot. Stepping on a trap is the dumbest move there is."
"What!?"
"Finn, can you handle it?"
"Huh? Oh—yeah, use position-shift magic to locate the traps."
Finn raised both hands.
"...Secondth."
A pale light radiated from Finn's palms.
The light stretched down the passage, touching walls and floor.
"Found them...! Right passage, three steps ahead, the floor. And the ceiling. Left side... five steps ahead, a magic thread."
Sweat beaded on Finn's forehead.
"Left. The right one collapses the moment you step on it."
"How can you tell!?"
"The stone color on the right floor is slightly different. The seams are new."
Mash tapped the right passage's floor lightly with his iron staff.
Rumble—
The floor caved in.
Below was deep darkness. Fall, and it's over.
"Whoa, seriously...!?"
Finn stumbled back.
"Can your Secondth cut the thread on the left?"
"I'll try."
Finn raised his hands again.
A blade of light sliced through the magic thread.
Snap.
"Good. Let's move."
The four advanced down the left passage.
The passage narrowed, darkened.
The air was cold.
A nasty sensation, like something crawling on the skin.
"...The air's heavy."
Finn murmured.
"The magic density is thick. Proof we're nearing their base."
Lance's blue eyes narrowed.
"Stay sharp. From here on, anything could happen."
Mash regripped his iron staff.
Then it happened.
"I've been waiting, Mash."
A voice.
It echoed quietly from the depths of the passage.
Mash's feet stopped.
A single man stood before the four.
Tall. Black robe.
His features closely resembled Mash's. No—Mash resembled him.
Domina. Mash's biological older brother.
An S-class mage allied with Innocent Zero.
"The more you try to protect your comrades, the more of them die. I taught you that."
Domina walked slowly closer.
"And still you came. Foolish little brother."
"Move, Domina."
Mash readied his iron staff.
"...Why go this far. You know Father's plan. The world will be rewritten. No matter how you struggle, the ending won't change."
"I'll change it."
"Why."
"I don't want to see a future where my comrades die. That's all."
Mash's voice was flat.
But those words carried a weight—like something long buried in his chest had become words for the first time.
Domina's eyes wavered, just slightly.
"...I see. Then show me with force. Whether your muscles can surpass time."
Domina raised his right hand.
"Time-manipulation magic—"
The air around Domina warped.
"—Chrono Freeze."
The world stopped.
Finn. Lance. Dot. None of them moved.
Air. Light. Sound.
Everything stood still.
In the last loop, Mash had lost to this magic without resistance.
He couldn't move a single finger.
But this time.
Mash closed his eyes.
(Time is stopped.)
(But my muscles are alive.)
He could hear his heartbeat.
Thump. Thump. Thump.
Blood flowing.
Muscles heating.
(Magic is made of mana flow.)
(Time-stop magic is the same.)
(Then I just have to sever that flow.)
Mash focused to the absolute limit.
Every muscle in his body screamed.
Bones creaked.
Veins bulged.
(I can see it...)
In Mash's eyes, the structure of Domina's magic came into view.
Countless threads. Threads of cause and effect. Binding this space.
(There.)
Mash clenched his fist.
His muscles swelled.
"—I'll figure it out with muscle."
Mash slammed his fist into the space before him.
Thud.
A dull sound.
The next instant—
Crack. Something shattered.
The air moved.
Light returned.
Sound flooded back.
"What...!?"
Domina's eyes went wide.
The time stop was broken.
"Im-Impossible... breaking time-manipulation magic with physical force...!?"
"Muscle can shatter even the cause and effect of magic."
Mash took a step forward.
"...Why, Mash. Why fight this far. The more you try to protect, the more the world takes from you. And still you—"
Domina's voice trembled.
"I don't want to see a future where my comrades die. That's all."
Mash repeated the same words.
That was all.
Domina stared at Mash for a while.
Complex emotions swirled in his eyes.
"...Go. Father is ahead."
Domina slowly cleared the way.
"Domina..."
"But next time we meet, I won't hold back. Your heart is necessary for Father's plan, after all."
With that, Domina vanished into the darkness.
"Ma-Mash... what just happened...?"
Finn stood stunned.
"I'll explain later. We need to hurry."
Mash started walking.
Finn, Lance, and Dot exchanged looks.
"...Let's go. Don't leave him alone."
Lance followed.
"Yeah! The protagonist of this world can't lose to that muscle idiot!"
Dot followed.
"Wait for me, Mash...!"
Finn broke into a run.
At the end of the passage stood a massive door.
Iron. Heavy. Cold.
Mash pushed it open with both hands.
Creak—
The door swung open with a heavy sound.
Inside was a vast stone chamber.
Countless candelabras lined the walls. Pale blue flames flickered.
And on the throne at the far end—
A man sat.
Black cloak. A mask covering the upper half of his face.
Bottomless magic radiated from him.
The leader of Innocent Zero.
Mash's biological father.
"Well come, Mash."
A low, heavy voice echoed through the space.
"...Dad, huh."
Mash readied his iron staff.
"Father, is it. You call me that. But I don't think of you as a son. You are merely the sixth vessel my plan requires."
The leader rose slowly.
"Six hearts. Five are already gathered. The final vessel is Anna Crown. The heart of the Crown family's youngest daughter."
"...I won't let you touch Anna."
Lance stepped forward.
His blue eyes burned with rage.
"Oh? The heir of the Crown family, renowned for gravity magic. But can your gravity stop my dark magic?"
The leader raised his right hand.
"Dark magic—Abyss Nova."
A black torrent burst from the leader's palm.
Darkness.
A pitch-black torrent that swallows everything.
It bore down on the four.
"Whoa...!"
"Secondth—Position Shift!"
Finn forcibly shifted the four's positions.
The dark torrent swallowed the spot where they'd stood.
The floor was obliterated.
"It's gone...!?"
"Finn, again. Delay that darkness, even for a second!"
"Got it! Secondth—Delay!"
Finn's light tangled around the dark torrent.
The darkness slowed, just slightly.
"Lance!"
"I know. Gravity Crush!"
Lance thrust out both hands.
Gravity within ten meters around them multiplied tenfold.
The dark torrent was pressed to the floor.
"Dot!"
"Been waiting! Taste the explosion magic of this world's protagonist! Controlled Explosion—Burst Spark!"
Dot unleashed explosions from both arms.
The controlled blasts scattered the dark torrent.
The darkness thinned.
"Now."
Mash ran.
Kicking off the floor.
One step. Two. Three.
The distance to the leader shrank.
"Futile. Mere muscle can't touch my dark magic."
The leader released darkness again.
The black torrent tried to swallow Mash.
Mash raised his iron staff.
(I can see it.)
(The mana flow of the dark magic.)
(Same as Domina's time magic.)
(Magic is built from mana structure.)
(Then I just have to crush that structure.)
"—I'll figure it out with muscle."
Mash slammed his iron staff into the dark torrent.
Clang—!!
Metal rang through the chamber.
The dark torrent split clean in two.
"What...!?"
Beneath the mask, the leader's eyes went wide.
"Your magic breaks under muscle."
Mash stepped in further.
The iron staff caught the leader.
"—It's over."
Mash drove the iron staff into the leader.
Thud.
A heavy blow.
The leader's body flew.
Slammed into the throne.
Debris crumbled.
"...Guh...! Insolent...!"
The leader rose from the rubble.
The mask was cracked.
Beneath it, a face closely resembling Mash's showed through.
"...Very well. I'll withdraw this time. But don't forget, Mash."
The leader smiled eerily.
"Of the six hearts, five are already in my hands. And the final vessel... is your own heart, Mash Burnedead."
Mash froze.
"Anna Crown was bait. To lure you here. Your heart is the final piece needed for the immortality ritual. You were born for my plan."
"...What, did you say."
"We'll meet again, son. Next time, I'll take your heart."
The leader's body was wrapped in black mist.
"Wait!"
Mash ran.
But he wasn't in time.
The leader vanished with the black mist.
"...Damn."
Mash slammed his fist into the floor.
The stone floor cracked.
"Mash... was that true? Your heart is the final vessel..."
Finn's voice shook.
"...Yeah. It's true."
Mash rose slowly.
His expression didn't change.
But blood seeped from his fist.
"...Let's go back. To Anna and Rein."
Mash started back the way they'd come.
When they returned to the academy, the eastern sky was beginning to pale.
Morning light faintly lit the trees of Noir Forest.
Lemon was waiting outside the infirmary.
"Mash! Everyone! You're safe!"
Lemon ran toward them.
Tears welled in her big red eyes.
"Yeah. Anna?"
"Yes, I stayed by her side the whole time. Her condition hasn't worsened. She's sleeping now."
"I see."
Mash gave a small nod.
"Lemon, thank you. For protecting Anna."
Lance bowed deeply to Lemon.
"Lance bowing...! No, I only did what was natural."
Lemon waved her hands in a fluster.
Then the infirmary door opened.
