The next day – Shibuya High
The air was different today. Whispers flooded the school hallways about the new transfer student who had single-handedly broken Jin Takeda's arm without breaking a sweat.
"Did you see it?"
"He didn't even stand up from his seat!"
"Jin's gang didn't even retaliate…"
Kaito Arashi walked through the halls, indifferent to the storm he had unknowingly unleashed. His sharp, cold gaze ignored the stares and murmurs. He just wanted a quiet life.
But the beast inside him — the one trained in every martial art imaginable — was already stirring.

Lunchtime – Rooftop
Kaito sat alone on the rooftop, enjoying his meal in peace. That peace didn't last.
"Yo."
Kaito didn't look up. He recognized the voice — Riku.
"You know you just declared war, right?" Riku laughed nervously, sitting next to him. "Jin was just a small fish. The higher-ups are definitely gonna come after you now."
"Doesn't matter." Kaito took another bite.
"…Man, you're crazy." Riku shook his head. "But honestly, I'm glad someone put Jin in his place."
Silence.
"You fight?" Kaito finally asked.
Riku laughed awkwardly. "Nah. I'm just good at running away."
Kaito smirked. Smart.

Meanwhile – Crimson Fangs' Headquarters
Jin sat with his arm in a cast, surrounded by his furious subordinates.
"That bastard broke my arm…! I want his head on a pike!" Jin roared.
"Calm down," a smooth voice interrupted.
The crowd parted as Renji Saito, the true leader of the Crimson Fangs, stepped forward. Unlike Jin, Renji was calm, calculating, and terrifyingly strong.
"He broke your arm without standing up?" Renji chuckled. "Interesting."
Jin gritted his teeth. "You gonna do something about it, Renji?"
Renji smiled coldly. "Of course. I'll break him publicly."

After School – Alleyway Behind Shibuya High
Kaito walked toward the train station when six figures stepped out of the alley. It was the Crimson Fangs — and leading them was Renji Saito.
"So you're the guy who humiliated my second-in-command," Renji said smoothly, cracking his knuckles.
Kaito stopped. His eyes met Renji's, reading him instantly. Dangerous.
"You gonna jump me or something?" Kaito asked.
Renji laughed. "Nah. I don't do gang fights. One-on-one. You win, you walk. You lose… well."
Kaito smirked. "Fine."
The gang backed up, forming a rough ring.
Renji stepped forward, raising his fists — a clean Muay Thai stance. "Let's see if you're as strong as the rumors say."
Kaito exhaled. No choice, huh? He slowly raised his own fists — a stance mixing boxing, wrestling, and kickboxing in perfect balance.
The fight began.

Round 1: Testing the Waters
Renji rushed in with a lightning-fast jab-cross combination. Kaito weaved effortlessly, his footwork honed to perfection. He countered with a brutal body hook — Renji barely blocked it, feeling the force vibrate through his bones.
What the hell… his power's unreal.
Renji retaliated with a Muay Thai clinch, aiming to crush Kaito with knees. Kaito counter-clinched, using wrestling techniques to destabilize Renji before slamming an elbow into his ribs.
"GHAAH!" Renji staggered.
The gang watching fell silent. Kaito wasn't just strong — he was a complete monster.

Round 2: The Awakening
Renji grinned, blood dripping from his mouth. "Alright… I'm done playing."
He lunged, unleashing a devastating barrage of knees, elbows, and leg kicks. Kaito absorbed the hits, his calm never breaking.
I can't lose here, Renji thought desperately.
Kaito suddenly exploded forward — a perfect double-leg takedown. Renji hit the ground hard, and before he could react — hammer fists rained down.
"STOP! YOU'LL KILL HIM!" one of the gang members screamed.
Kaito froze, his fist inches from Renji's unconscious face. His breathing was calm. Too calm.
He stood up. "…Don't bother me again."
And just like that, he walked away.
The Crimson Fangs watched in silence. A beast had been unleashed.
