Official Prologue : The Physics of Frictio.
"Water remembers every shape it holds; ice remembers the force that broke it. But when the two collide, the laws of thermodynamics rewrite themselves entirely."
The chlorine in the Aqua Dome didn’t just smell like chemicals; to Ren Shinozuka, it smelled like a courtroom.
At exactly 5:15 AM, the facility was a cathedral of glass and undisturbed blue.
The surface of the Olympic pool was an absolute, flawless sheet of liquid glass.
Ren stood on the edge of Block 4, his toes gripping the textured plastic, his wide swimmer’s shoulders cutting a sharp silhouette against the dawn light filtering through the high rafters.
He adjusted his goggles, exhaled a long, measured breath, and let his mind go completely blank.
Zip.
He parted the water without a splash.
To the untrained eye, Ren’s stroke was art.
To his father, it was a sequence of mathematical data points. Keep the elbow high.
Rotate the torso exactly forty-five degrees.
Kick from the hip, not the knee.
Every stroke was a debt he was paying back to a surname that carried three Olympic gold medals.
He didn’t swim because he loved the water; he swam because the deep end was the only place on earth where nobody could ask him to speak.
Then, the heavy double doors of the Aqua Dome didn't just open—they slammed against the wall with a thunderous, metallic crack.
"Move it, move it, move it!
We’ve only got forty minutes before the ice maintenance crew locks us out of the auxiliary gym!"
The voice was loud, raspy, and thoroughly unbothered by the sacred silence of the morning.
Ren choked on a breath, breaking his rhythm.
He broke the surface, his dark hair plastered to his forehead, his obsidian eyes narrowing as he gripped the lane rope.
A hurricane had just marched into his sanctuary.
Leading the pack was a girl with a high, bouncing ponytail, wearing an oversized, faded black hockey jersey with a jagged "C" stitched onto the chest.
Yuki Nakamura was dragging a massive canvas gear bag that smelled aggressively of old sweat, rubber, and cold synthetic leather.
Behind her, a chaotic trail of muddy sneaker prints defiled the pristine, sterile tile floor.
"Hey! Ponytail!"
Ren’s voice cut through the echo of the dome, deep, rough from the water, and dripping with immediate irritation.
He rested his forearms on the lane line, staring her down. "You’re tracking mud all over the pool deck.
Get those bags back outside.
This is a restricted training zone.
"Yuki stopped dead in her tracks.
She slung a heavy composite hockey stick over her shoulder, turning her amber eyes toward the pool.
She looked at the clear water, then looked at Ren, her expression shifting from rushed panic to absolute, unadulterated skepticism.
"A restricted zone?"
Yuki scoffed, planting her free hand on her hip.
"Listen, Mr Speedo, I don’t care if you’re the prince of the puddle.
The athletic department screwed up the scheduling.
The ice rink's compressor blew out, and Lab 4 assigned us the dry-land floor space in this building for the next two weeks. So unless you want to skate across that pool, I suggest you stay in your lane.
"Ren’s jaw tightened."The sign on the door says Swimming Team Only."
"And the paper in my hand says otherwise,"
Yuki shot back, flashing a crumpled printed schedule like a weapon. "
I’m Yuki Nakamura, captain of the hockey team.
And we don't back down from a fight—especially not with a guy who hides from land."
"Ren Shinozuka," he replied, his voice dropping an octave, carrying the heavy gravity of a name that usually made people apologize..
Yuki didn't even blink. She just cracked a sharp, mocking grin that sent a strange, unexpected spark of friction straight through the humid air of the dome.
"Never heard of you, Shinozuka. Welcome to the ice age.
"One belonged to water.
One belonged to ice.
The temperature in Hanzawa University was about to drop to absolute zero.
