Gunzo

Heir to a brutal Yakuza clan long thought erased, Ryuji walks the school halls like a ghost—quiet, cold, untouchable. In the underworld, they whisper his name: The Black Vow—a living curse, bound to a promise written in blood.
His target? The syndicate that slaughtered his kin.
His obstacle? Their daughter… the only one who’s ever seen through his silence.

The Boy Of Promise

Ryuji's eyes sharpened. His body shifted like water—fluid, precise.

The guard's legs folded, crashing into the dirt with a guttural cough.

The second was faster, stronger—but predictable. Ryuji met him head-on. A hook, a knee, and a ruthless elbow to the jaw.

He hesitated. Rage boiling beneath humiliation. Then he lunged with a desperate scream.

He caught the punch. Twisted. Slammed Sora against the tree behind them.

"The Kamaguchi? You're nothing. A bunch of suits hiding behind words and money."

"You thought you were playing a game of power and dominance? No. You've just been playing game of kids."

"But now... you're standing in front of Vengeance ."

"You think you're ready for this world? You don't even know what blood smells like."

He shoved him down. Sora collapsed in front of the stunned crowd.

Ryuji's voice cut through the silence like a blade:

"You wanted war. Now you're in it."

The once untouchable student council president—the feared heir of Kamaguchi—shook like a leaf.

"You don't belong in the ring with me, Kamaguchi."

Aika and Kaito saw everyting with their own eyes for the first time they saw the real Ryuji "The Black vow"

The kind of silence that echoes long after it falls.

And in that silence, Sora Kamaguchi felt something he'd never known before.
