The arena had gone loud, then quiet, then something in between - the kind of hush that learns to breathe around a heartbeat.
Two figures stood at the edge of a ruined concourse. Raizen rolled his shoulders once, blade low, weight settled. Hikari set her staff across her back like a line drawn on purpose. The floor between them had been a market once - stalls blown open, signs hanging from one bolt, a tram car sunk at a bad angle like it had tried to pretend it was a boat and failed.
The host tried to be himself. The mic cracked. "Final two on deck. If you're holding your breath, please pass it to a friend when you faint." Then he stopped talking like that and let the bowl hear his real voice. "Neoshima… You might want to watch this!"
The scoreboard thinned to two names that glowed brighter for being alone.
Hikari moved first - not big, not fast - a small test to see how the ground wanted to answer. She tapped the staff into her palm, set her stance so narrow it looked like a mistake and wasn't. Raizen eased a half step left, blade angled, eyes on her hands, not her face. The suits at their spines held at yellow for both. No red. Not yet.
They closed in at the same time.
Steel clicked with a sound like someone snapping a bone clean. Raizen cut short and honest, no flourish. Hikari turned the staff down the line and slid his strike into empty. He rode the miss into a guard that caught her return. A second clack. A third. Their hands did more talking than their legs. The first exchange drew a line through two stalls and across the tram's broken step. Raizen cut low. Hikari lifted. The staff hit one of his blades and redirected it by two fingers. He let it go and reclaimed the angle she'd given him. She accepted the loss and stole half of it back. The floor decided to be kind and stayed flat.
A blue filament woke inside Hikari's staff. It crawled the length of the handle and spine like a river given a bed, then brightened to marks that pulsed when she changed grip. The crowd saw it and forgot how to be polite. The host whistled between his teeth. She took a wide but devastating swing. Raizen didn't blink. His blades crossed, parrying with a small, extremely faint golden pulse. Luminite to Luminite - two tempos, two colors, two promises.
Hikari struck again - a step-in that felt too simple until it wasn't. The staff came at his wrist, changed its mind midair, and turned for his throat. He slipped back, let it miss by a breath, then punished the recovery with a cut at her hand. She wasn't fast enough to counter it. He pushed her toward the tram and she turned it into a springboard. One foot on the step, twist, staff low for balance, then she was over his shoulder and past. The blue lines flared, leaving a memory of her angle hanging in the air like a chalk mark.
He pivoted and met her on the return. The blade talked to the staff again - flat to flat, edge to edge, a scrape that made teeth itch. She slid inside his guard, only to cut the space she wanted on the way out. The suits ticked a degree hotter. The host forgot a joke and said the first thing that came to his mind, the most obvious thing there was.
"They're fast."
The arena changed its mind about being still. A panel fell to the ground with a slow, rude sigh. The cords holding it couldn't hold anymore. Dust lifted, got caught in a hole where a roof used to be. Raizen crossed the new gap like he'd known it was arriving. He jumped in the air, and performed a rotating attack, with both his blades like a deadly spinner. She barely managed to save herself, with the staff almost missing the twin blades, that hit with a force that said "Oh, I'm not holding back!". The blue along her staff bled brighter. She smiled - small, quick, real.
He pressed. She yielded and then stole the center from underneath him. The staff traced short circles that became traps if you looked for them. He didn't look. He moved his feet, trusted his hips, let his shoulders be quiet. A cut, a guard, a half beat where her elbow got lazy - he tried to take it. She didn't let him, burned the mistake away with that blue light and made his attempt feel like it belonged to her. Raizen kicked through it and came on with the kind of pressure that convinces a room to be smaller. Hikari let the room shrink and wrote the terms on its walls. Her face didn't change. His tightened with effort and then didn't.
The crowd's sound changed color. Awe and silence sat where laughter had lived.
He felt the old edge of anger knock at his chest and didn't open the door. Something else lived there now, and it made better choices. He drove her into the narrowest part of the concourse - broken beams overhead, a stagger of stairs down to a platform on the right - and tried to make her learn a new rhythm. She let him think it was working for three beats. On the fourth she slid left, hit his guard with the end cap of the staff as if to say "no," and rewrote the whole strategy.
His nose started bleeding a minute later. He didn't notice until a red line found his lip and stung with salt. The suit at his spine chirped once like a friend clearing its throat. He wiped the blood with the back of his wrist and didn't use the back of his hand like a child.
Hikari saw it and didn't weaken. She stepped in, blade end high, and made the air whistle with a cut that turned into a feint that turned into the real strike half a blink later. He had no right to be there when it landed. He was anyway. Blue met golden and refused to lose. The impact cracked the tram window. The rest of the window gave up a second later. Glass fell like bright rain.
The host leaned into a hundred mics and forgot format. "They're breaking the building. They're breaking the - yes - yes, okay. They should be stopped, but MAN, IS THIS INTERESTING TO WATCH!"
They crossed a bridge that used to be a clothesline. Fast blows and hits trading. Hikari's staff rang links and drew lines the color or pure lapis through dust. Raizen's blade took the lines apart and left clean edges where mess had been. He cut a cord, stepped, she cut another, stepped, until the bridge was half a bridge and they had no right to still be on it. They were anyway. He grabbed a pipe and swung. She used the staff like a lever against the frame and flipped past, hair brushing metal, blue bright enough to paint her jaw.
Her suit pulsed dark orange. His held orange. Neither of them looked at the lights. The bowl did that for them.
They hit the ground and didn't stop. The fight found a long corridor made of what once were supposed to be broken storefronts. He shoved a stall into her path - not dirty, not clean, just honest - and she vaulted it with the kind of ease you get after you wear thin your fear of falling. She tapped the staff twice on the way down and the blue flared along carved lines that hadn't been visible before. For a heartbeat it looked more like a conduit than a spear or staff. The next strike sang with it. She met the it with the staff turned flat, on the ground. The block echoed through both his bones and hers. She staggered two steps. He slid and almost missed the landing. The suit at his spine went hot then cooled in a pulse that said - careful.
He exhaled through his nose and the blood came again.
The arena lost another wall. A support beam decided its contract had expired and left its post. The floor on the far side sank two inches and everyone's stomach learned something about gravity. The stands went very quiet for a breath, then remembered how not to panic.
Hikari moved differently. Less human, more perfect. She caught his wrist with the middle of the staff and turned the joint until it remembered where it lived. He let it go to save the elbow, turned his palm, slashed for the ankle, and hit shin instead. The blue took the hit and the staff hummed hard enough to shake dust from rafters. The suit chirped again. Orange held. Dark orange blinked. Their chests worked like bellows that meant it. Sweat cut tracks through dust on both their faces. Her hair stuck to her neck. His shirt stuck to his shoulders. Every cut started from the legs and ended in the floor.
They got even meaner - not cruel, honest. He hooked her staff with the guard, ran it, tried to trap her grip. She let him and used the moment to step inside his balance and try to take the throat. He made those inches a long road and took them back. She tried a sweep that should've bought her time. He kicked it just enough to get it off-trajectory and punished it with a pommel to the ribs that would bruise. She answered with a line down his forearm that'd look like someone had tried to write a curse on his skin.
"Keep your feet."
They did. Barely.
Hikari rolled her shoulders like she was shaking glass off. The blue along the staff steadied. She stepped, attacked, cut. He blocked, tried a swing, dodged. They went into it for real, trading more and more hits. Two different blades versus a staff with two ends. Equally dangerous.
Then, the completely unexpected happened. The floor collapsed as if the stakes would add to the weight. Raizen and Hikari both fell down, their suits flashing again. Not red. Though. Not yet.
They were at the very center again. Like at the start of their duel. Quite far apart, though.
"Finally," he said.
Her mouth twitched. "Show me."
He did.
"Now," Kori would've said.
He didn't hear her voice. He heard the letter instead - keep the world lit - and the way the words had sat between the two cups on the table. He let the thought be his rhythm. He let the gold be his breath.
Despite the considerable distance between them, he stepped back, opened his guard, and let the Luminite in his blade teach his bones how to truly race. The warm light along the spine brightened until color became pressure. The air around him lifted the hair on arms three rows up. The host screamed something that sounded like "oohhh" with too many syllables. It felt like golden lightning itself decided to come down and fuse with luminite. He exhaled. Then, a flash. Gold ripped a line through dust and left a howl where footsteps should've been. The speed was immense... Actually, the dash didn't even look like speed anymore. The world seemed to stretch thinner than you could understand matter itself. Instant, absolute
Then, silence.
After the smoke cleared, everyone could see it.
The tip arrived at the space under Hikari's jaw at the exact moment her staff couldn't be there. He didn't touch her skin. He didn't need to. The line had been drawn.
Her suit finally flashed red.
She looked at him - not down the blade. At him - and for the first time all morning her mouth softened into something like a secret shared.
"You got me," she said.
He let the blade fall a finger. His knees told him the bill for the dash had arrived. His chest burned like rusted air. His nose found more blood. The suit stayed dark orange because it was busy lying for him.
The host found his voice and lost the show. "Hikari - red. Clean. Raizen… WINS!!!"
The bowl didn't roar at once. It breathed out first, like a city that had been holding itself tall and could finally put its shoulders down. Then it erupted. The sound climbed the petals and tried to make a roof out of itself.
His fingers loosened. The blade kissed the ground, then lay, sick of being asked to be more than metal. His legs went the way doors go when the hinges finally get their say. The suit tried to be helpful and wasn't. He went forward and down, curling a shoulder at the last second like Kori had made him practice until he hated her and loved her for it.
The last thing he saw was Hikari stepping in. Maybe to catch him, maybe just close enough that the ground wouldn't be so rude
The lights overhead blurred. The gold in his blade cooled to a coin at the bottom of a well. The host said something that sounded far away.
Raizen's eyes closed.
Everything else kept moving.
