Chapter 1 — The Sky Falls
The forest was burning.
Kohaku ran for her life. Flames roared behind her like a living beast, devouring trees and exploding branches into showers of sparks that rained down around her in violent bursts. Thick, choking smoke clawed down her throat and burned her eyes with every desperate breath she dragged in. It tasted bitter, metallic, suffocating. Her lungs felt raw, like they were tearing open with every inhale. Her legs screamed with exhaustion, muscles shaking, threatening to give out beneath her, but she forced them forward anyway. Harder. Faster. She didn’t slow.
Sweat mixed with ash poured down her face, streaking through the dirt and soot. Her heart pounded so violently it hurt, each beat slamming against her ribs like it was trying to break out.
“She’s there! Don’t let her reach the cliff!”
The Empire’s soldiers screamed through the smoke, their voices sharp, furious, closing in. Gunpowder explosions ripped through the woods. One blast detonated so close that the shockwave slammed into her back like a giant fist, knocking the breath from her lungs and lifting her off the ground for a split second. Dirt, burning leaves, and hot embers tore across her skin. She hit the ground hard, pain shooting up her side, rolled instinctively, and forced herself back up before her body could register the damage. Her legs shook violently but she moved anyway.
She vaulted over a fallen log, her boots slipping on wet moss and loose dirt, nearly sending her crashing again. Her golden hair whipped behind her, tangled, heavy, filthy with smoke and sweat. The dagger strapped to her thigh slammed painfully against her leg with every stride, a sharp reminder she was still alive, still moving.
The roar of the waterfall grew louder ahead, deafening, swallowing everything except the fire and the men hunting her.
Through the haze she finally spotted it.
The hot air balloon.
A fragile silk bubble fighting desperately against the violent winds, swaying, straining, barely holding its shape right above the falls. Too far. Too high. Too unstable.
But Senku was there.
That single thought cut through everything else. It shoved her forward when her body was already failing. It forced her legs to move when they wanted to collapse.
Another explosion tore through the trees right behind her. The force hurled her forward, almost ripping her off her feet. She burst out of the treeline, boots slamming onto jagged rock as the ground shifted beneath her.
The cliff edge crumbled.
There was no stopping.
She leapt with a wild scream into open air and mist.
⸻
High above in the swaying basket, chaos ruled.
“Target vector’s slipping!” Gen shouted, voice high, breaking under pressure, knuckles bone-white as he clung to the burner rope like it was the only thing keeping him alive.
“The updrafts are destroying our lift! We’re getting dragged toward the falls!”
“Hold it steady!” Senku snapped, his voice cutting clean through the panic.
His eyes locked onto the burning forest below.
A flash of gold.
Kohaku.
Everything else disappeared.
He moved instantly.
He ripped an iron brace free from the basket frame with brutal force, metal screeching as bolts tore loose and flew. The entire balloon lurched violently, tilting hard. Chrome stumbled, bracing himself, swearing under his breath as the floor shifted beneath him.
Senku didn’t stop.
His hands tore open against the rough metal, skin splitting as he grabbed a heavy coil of cable. Blood smeared across the iron as he wrapped it fast, tight, twisting it with raw force, locking it in place.
“Chrome, brace it now!”
Senku leaned dangerously far over the edge, half his body outside the basket as the wind tore at his coat, his hair whipping violently across his face.
“KOHAAAKU!”
He threw the iron bar with everything he had.
The makeshift spear cut through smoke and mist, the cable screaming behind it as it unraveled.
⸻
Kohaku was already falling.
The world dropped out beneath her. The roar of the waterfall swallowed everything. The mist slammed into her skin, cold and violent.
The bar shot past her.
She missed it.
Her fingers clawed at empty air.
For one split second, she thought that was it.
Then she caught it.
Both hands.
The cable snapped tight.
Pain exploded through her shoulders and arms like they had been ripped from their sockets. White-hot, blinding, violent. It tore a scream out of her throat before she could stop it. Her body jerked hard, swinging violently, the force nearly ripping her grip away.
But she didn’t let go.
She locked her hands tighter, teeth grinding, muscles screaming, refusing to release.
Her body hung there, suspended over nothing, swinging like a broken thing above the roaring, endless drop.
⸻
The weight hit the balloon.
Hard.
The basket dropped violently, wood groaning, ropes straining, the entire structure tilting at a sickening angle.
“We got her!” Chrome shouted, grabbing the rope with both hands, planting his feet, pulling with everything he had.
Senku locked the cable down, securing it fast. “Hold steady!”
The balloon fought them.
Wind slammed into the silk, warping it, crushing it inward. The burner flame flickered, weakening, struggling to stay alive. Freezing spray from the waterfall blasted up into the basket, soaking everything instantly. The floor turned slick. Their hands slipped, burned, struggled to hold.
The entire basket dropped again.
Feet.
More.
The roar of the water below got louder.
“Kohaku, climb! Now!” Senku shouted.
⸻
She climbed.
Hand over hand.
Each pull tore through her arms like they were shredding apart. Her muscles trembled violently, barely responding. Her boots kicked uselessly at empty air, searching for something that wasn’t there.
The mist hit her face like needles, sharp, cold, relentless. She could barely see.
But she kept climbing.
⸻
“We’re too heavy!” Gen’s voice cracked completely now, fear ripping through it. “The balloon can’t carry all of us! We’re sinking straight toward the falls!”
⸻
Kohaku dragged herself over the rim.
The second her weight shifted into the basket, the silk sagged.
The balloon dropped.
Fast.
The world tilted downward as jagged rocks and raging white water rushed up to meet them.
There was no time.
Kohaku understood instantly.
Her face went pale.
She moved.
She grabbed Senku’s collar with both hands, fingers trembling, pulling him forward hard, forcing him to look at her.
“Senku… thank you. For everything.”
Then she kissed him.
Not soft. Not hesitant.
Desperate. Fierce. Almost violent.
She crushed her lips against his, gripping his coat so tight the fabric twisted and bunched in her fists. Her entire body leaned into it like she was trying to hold onto something that was already slipping away.
Senku’s mind went completely blank.
Everything stopped.
This was Kohaku.
The warrior. The fighter. The girl who stood in battle without fear.
And she was kissing him like the world was ending.
His heart slammed violently against his ribs.
Chrome froze.
Gen froze.
No one moved.
⸻
She pulled back.
Barely.
Their faces inches apart. Her breath unsteady, eyes burning, wet, fierce, alive.
“Take care of Suika. Tell her I said goodbye.”
“Kohaku, don’t—”
She stepped onto the rim.
⸻
Senku moved.
Slow.
Too slow.
His hand reached for her like it was fighting through something heavy, something dragging it back. His fingers shook.
They touched.
Barely.
Her fingertips brushed his.
One heartbeat.
Her golden hair floated around her face, wild in the wind. Her eyes never left his.
Pain.
Love.
Final.
⸻
She let go.
She fell backward into the mist.
Gone.
⸻
“KOHAAAKU!”
Senku launched himself over the edge after her without thinking.
Chrome and Gen slammed into him, grabbing him hard, arms wrapping around his chest and waist, dragging him back with everything they had.
“No! Let me go!” Senku screamed, voice tearing apart, raw, unrestrained. “KOHAAAKU! KOHAAAKU!”
He fought like an animal.
Elbows drove back. His body twisted violently. His boots scraped against the slick floor as he tried to throw himself free.
“She’s still alive down there! I can reach her! LET ME GO!”
Chrome was crying openly now, grip locked, refusing to let go. “Senku, stop! You’ll die too!”
Gen held on, shaking, tears streaming down his face, voice breaking. “It’s too late… it’s too late…”
Senku didn’t stop.
He kept screaming her name.
Again.
Again.
Again.
Until his voice started to break.
Until it turned raw.
Until it started to tear.
⸻
The balloon surged upward.
Freed from her weight.
Violently.
⸻
His hands clawed at empty air.
Grasping for nothing.
The mist swallowed everything below them.
⸻
The roar of the waterfall faded.
Slowly.
Too slowly.
⸻
Only wind.
And the sound of him breaking.
“Kohaku… Kohaku…”
His voice cracked.
Faded.
Died.
“There should have been a way…”
And then there was only sky.
